What is polyethylene oxide used for

What is polyethylene oxide?

Polyethylene oxide, abbreviated PEO(poly(ethylene oxide)), is produced by ring-opening polymerization of ethylene oxide (also called ethylene oxide). It is an important water-soluble polymer material. It has a wide range of applications, including paper, electrical appliances, construction, mining, medicine, agriculture, textiles, printing, oil extraction, municipal engineering, washing and personal care products.

Characteristics of Polyethylene oxide

Polyethylene, Oxidized completely soluble in water, soluble in some organic solvents. The solution has high viscosity at low concentration. It is a soft, high strength thermoplastic resin. It can be processed by calendering, extrusion, casting, etc. Resistant to bacterial attack, will not corrupt, in the atmosphere hygroscopicity is usually not large; The high polymer has flocculation; Good compatibility with other resins.

What are the uses of Polyethylene oxide in the daily chemical field?

1. In the shampoo system, the use of high molecular weight polyoxyethylene (PEO) and cationic hydroxyethyl cellulose at the same time can provide excellent conditioning properties. Cleaning hair with a formula containing cationic hydroxyethyl cellulose and high molecular weight PEO results in a 30% improvement in wet combing compared to a formula containing only cationic hydroxyethyl cellulose. Used in combination with PEO. The adsorption capacity of cationic hydroxyethyl cellulose controlled silicone oil and octyl methoxycinnamate increased by 27% and 25%, respectively.

2. Due to the non-toxic and gelatinizing properties of PEO, it is used as one of the components of denture fixation agents, which can play a buffer role between dentures and the mouth, and also help to reduce unpleasant odor and taste.

3.PEO aqueous solution is a pseudoplastic liquid. Due to its viscosity sensitivity to shear rate, it can be used as a contact lens, that is, a contact lens solution, and bacteria are not easy to grow on PEO to maintain contact sterility.

4. The mixture containing PEO can be used as a skin cleanser (such as detergent, hand soap, etc.), which has good foam properties and is easy to be washed off, making the skin soft and smooth.

5.Polyethylene, Oxidized can also be used as a component of teeth whitening solution to obtain good teeth whitening solution. It is also used as a component of shaving cream to form a thin film on the face for non-foaming shaving.

6. The absorbent resin made of PEO after crosslinking can be used in women’s sanitary napkins and baby diapers.

What are the uses of Polyethylene oxide in medicine?

1.The aqueous solution of PEO is coated on the outer layer of the pill to make a controllable slow-release drug, which has been widely used in the pharmaceutical industry to control the diffusion rate of the pill ingredients in the body and improve the efficiency of the pill. The long chain of the PEO polymer and the water molecules it binds to act as a barrier to protect the modified drug from enzymatic degradation, rapid clearance by the kidney, or interaction with cell surface proteins, thereby reducing adverse immune effects. The range of pH and temperature stability of PEO-modified drugs is also extended relative to non-PEO-modified drugs. After PEO modification, the water solubility of polypeptide drugs increased, kidney clearance slowed down, toxicity decreased, so that its pharmacokinetics and pharmacodynamic properties were significantly improved. The study shows that the synthesis of branched polyoxyethylene and modification of cisplatin. The cytotoxicity and acute toxicity of cisplatin modified by linear PEO and dendritic PEO were compared. The half-inhibitory concentration of cisplatin modified by dendritic PEO was lower than that of linear modified products with the same molecular weight, but there was no significant difference in acute toxicity.

2. Due to the non-toxicity and high viscosity of polyethylene, oxidized (PEO) can be used as one of the components of denture fixative, which can play a buffer role between denture and mouth, and also help to reduce unpleasant odor and taste.

3. Polyethylene, Oxidized (PEO) aqueous solution is a pseudoplastic liquid that uses its viscosity as a contact lens solution due to its sensitivity to shear rate, and it is not easy for bacteria to grow on polyoxidized ethylene (PEO) to maintain contact sterilization.

What is SMFP

Brushing teeth is something people do every day, and for the sake of oral health, people have to brush their teeth twice a day in the morning and evening. So how should we choose toothpaste? The main function of toothpaste is to clean teeth. Toothpaste is essentially a cleaning agent, and its basic function is to clean the oral cavity. If it has whitening, cavity prevention, desensitization, hemostasis and other effects, it is only auxiliary. At present, the common toothpaste additive in toothpaste is SMFP. Let’s take a look at SMFP.

clean-teeth

What is SMFP?

SMFP is actually sodium monofluorophosphate, CAS number 10163-15-2. It is a white powdery solid with a melting point of about 626 ℃. It is easily soluble in water and has strong hygroscopicity. SMFP is a dental toothpaste abrasive, anti caries agent, and desensitizer used to protect the source of fluoride toothpaste treatment, with a total cost of 0.8%. It also serves as a raw material for preparing monofluorophosphates for fluoride content in drinking water and metal surface cleaning agents.

SMFP is a widely used toothpaste additive worldwide, used as an anti caries agent and toothpaste desensitizer. In addition, it is also used as a preservative and bactericide. The conventional addition amount in toothpaste is 0.76% by weight.

tooth

Is SMFP safe?

SMFP is an inorganic compound, and sodium monofluorophosphate can play a role in preventing tooth decay and improving tooth sensitivity in toothpaste. For pregnant women, sodium monofluorophosphate toothpaste can be used, but attention should be paid to the amount used to avoid excessive intake. For children, especially those under 6 years old, it is not recommended to use toothpaste containing sodium monofluorophosphate, as children may swallow toothpaste and long-term ingestion may cause fluorosis, leading to tooth deformities, softening, loss of enamel luster, and other problems.

Overall, SMFP toothpaste is beneficial for dental health, but caution should be exercised when using it in moderation, especially for special populations such as children and pregnant women.

What is SMFP used for?

SMFP application in toothpaste

Sodium monofluorophosphate is widely used in fluoride toothpaste, which can promote tooth remineralization and prevent tooth decay. It has good therapeutic effects on people with sensitive teeth and does not irritate teeth after use.

SMFP application in Food

Sodium monofluorophosphate can be used as a food additive in food as a source of fluorine. Some of the chewing gums we are familiar with include sodium monofluorophosphate in the raw materials, which makes these gums have functions such as caries prevention, desensitization, antibacterial and sterilization.

SMFP

SMFP application in medical field

Sodium monofluorophosphate can promote bone cell differentiation and diffusion, leading to an increase in bone mass.

Metal surface protection agent——Octadecanethiol

Octadecanethiol is an organic sulfur compound with the chemical formula C18H38S. Octadecanethiol is liquid clear, transparent and oily at temperatures above 35 degrees Celsius, and solid white wax at temperatures below 35 degrees Celsius.

Octadecanethiol is mainly used in electroplating additives, surfactants, etc., as a protective agent for nickel, copper, tin, gold, silver plating, improving salt spray and functionality. The coating layer is uniform and not easy to yellow, the surface washing ability is good, and the corrosion resistance of sulfide is strong. Octadecanethiol is a master of metal protection and has significant effects in protecting metals. When exposed to air, metals are often vulnerable to oxidation, which leads to corrosion. And octadecanethiol is like a “metal bodyguard”, it can form a protective film with the metal surface, blocking oxygen in the air, so as to effectively resist the damage of corrosion. It is like putting a strong suit of armor on the metal to protect it from the claws of corrosion.

Mercaptan is one of the widely used film forming agents in water-soluble gold and silver protective agents. In fact, research on the protection of silver faces dates back to the 1930s. There are two main protection methods adopted at the earliest. One is to use thiazole, imidazole, mertan and other organic substances to react with silver surface to form an organic film, which covers the silver surface to play a protective role. The other is the use of aluminum chloride, lithium chloride and other salts, using their own hydrolysis reaction, the formation of colloids to fill the silver gap, so as to achieve protection. In recent years, through the study of polymer chemistry, the selection of emulsifiers, and the screening of organic membrane components, the performance of silver surface protectants has reached a good effect.

In many experiments, dodecyl mercaptan, tetradecyl mercaptan, hexadecyl mercaptan and octadecanethiol  have been proved to be more effective mercaptan. Among the mature formulations, hexadecylmercaptan and octadecylmercaptan are more commonly used. UNILONG is a professional manufacturer of mercaptan series products such as octadecanethiol, specializing in the research and development and sales of plating brightener intermediates and plating additives, and independently producing silver plating brightener intermediates. In the application of metal environmental protection agent core materials, we have specially prepared special octadecanethiol  and 1-Docosanethiol according to the performance of protective agent film formation, which has shown excellent performance in new energy silver plating anti-vulcanization test and sulfuric acid boiling test.

The 1-Docosanethiol chemical formula is C22H46S. 1-Docosanethiol is liquid clear, transparent and oily at temperatures above 50 degrees Celsius, and solid white wax at temperatures below 45 degrees Celsius. 1-Docosanethiol can make up for the deficiency of octadecanethiol, the film natural curing fast, good surface washing, strong corrosion resistance. It has good application in coating and mechanical polishing protection of silver jewelry.

Of course, in addition to metal protection can play a vital role, as an important raw material for organic sulfide synthesis, it is also used in industrial production, daily chemical supplies and other fields.

For example, in cosmetics, octadecanethiol can be used as a beauty and skin care ingredient, with multiple effects such as antioxidant, moisturizing and soothing inflammation. At the same time, it is also a natural sunscreen, it has good light absorption properties, can effectively absorb ultraviolet rays, protect the skin from damage. In addition, octadecanethiol can also be used to prepare soft rubber products, so that it has better elasticity and wear resistance.

In addition, as a common organic sulfur compound, octadecanethiol is also widely used in the field of cleaning agents. Due to its strong solubility and decontamination effect, it is widely used in cleaning agents and descaling agents. In industrial production, octadecanethiol cleaners can be used to remove oil stains on machinery and equipment, candle stains and other difficult to clean dirt. In daily life, octadecanethiol cleaners can be used to clean surfaces such as kitchen utensils and bathroom facilities, effectively removing stubborn stains and maintaining cleanliness.

Finally, octadecanethiol is also very important in chemical experiments. Due to its low volatility and extremely low toxicity, it is ideal for many industrial and laboratory applications. In chemical synthesis, octadecanethiol can be used as a solvent to dissolve and catalyze the reaction substance, promote the reaction, accelerate the reaction speed, and improve the efficiency of chemical synthesis. In addition, it can also be used as an extractant to separate and purify organic compounds, thus playing an important role in chemical research and industrial production.

In short, the unique properties of octadecanethiol make it an indispensable and important substance in metal protection, chemical synthesis, industrial production and daily chemical products. With the continuous development of science and technology, we can foresee that the application of octadecanethiol in more fields will continue to expand and deepen.

What is sodium monofluorophosphate

We need to brush our teeth every day, then we need to use toothpaste, toothpaste is a daily necessities that must be used every day, so choose a suitable toothpaste is crucial. There are many kinds of toothpastes on the market with different functions, such as whitening, strengthening teeth and protecting gums, so How to choose the right toothpaste?

Now there are many kinds of toothpaste, usually different toothpaste will have its different effects, in fact, whether it is cheap or expensive toothpaste, the purpose is to help clean teeth, therefore, when we buy toothpaste, do not only look at the price, think that the expensive must be good, expensive out is some additives, such as some anti-allergy, hemostatic, whitening and other ingredients. In fact, the main component of toothpaste is the friction agent, the common friction agent are, calcium hydrogen phosphate, calcium carbonate and calcium pyrophosphate, of which, calcium carbonate friction is relatively strong, generally used to clean teeth of tea and smoke stains.

However, some people like to choose fluoride toothpaste, especially every time the tooth decay tormented sleep. It is an indisputable fact that toothpaste contains a small amount of fluorine, which can play a role in preventing dental caries. So you can use fluoride toothpaste to prevent. When it comes to fluoride toothpaste, the ingredients that have to be mentioned are sodium fluoride and sodium monofluorophosphate.Let me show you the difference between the two.

What is sodium monofluorophosphate?

Sodium monofluorophosphate is an inorganic compound, referred to as MFP, CAS number 10163-15-. MFP has the chemical formula Na2PO3F, is a white crystalline powder, soluble in water. Sodium monofluorophosphate is broken down by acid or salivary enzymes in the mouth, releasing fluoride ions, which react with crystals on the surface of tooth enamel to form fluorapatite, thereby enhancing tooth resistance and inhibiting dental caries. Sodium monofluorophosphate is widely used in food additives, toothpaste, metal cleaners, special glass, skin care cosmetics and other fields, especially in toothpaste, it is used as one of the main components of anti-caries toothpaste. It is generally one of the toothpaste formulations, has basically replaced sodium fluoride in some products, and has gained an advantage in competition with tin fluoride.

Sodium monofluorophosphate is an excellent anti-caries agent and tooth desensitization agent, the conventional content of fluoride in toothpaste is 0.10– 0.12%, but also has a strong bond tooth function, sodium fluoride is an anti-caries agent, mainly used as a fluoride toothpaste additive, the conventional content of fluoride in toothpaste is 0.7– 0.8%, Fluoride in toothpaste can be combined with minerals in the mouth to form fluorapatite, strengthen the protective layer of the tooth surface, high fluoride content, better anti-decay effect, monofluorophosphate compared with sodium fluoride, monofluorophosphate contains more fluorine, so sodium monofluorophosphate anti-decay better.

In fact, sodium fluoride and sodium monofluorophosphate are two different compounds, and they have different chemical structures and application fields.

What is sodium fluoride?

Sodium fluoride (NaF) is an inorganic compound with the formula NaF. Its main applications include as phosphating promoters, agricultural pesticides, sealing materials, preservatives and so on. Sodium fluoride is also used in the medical field to prevent cavities and strengthen teeth, but its role is mainly to provide fluoride, rather than through the mechanism of sodium monofluorophosphate.

In summary, although sodium fluoride and sodium monofluorophosphate overlap in some applications, their mechanisms of action and specific applications are different. Sodium monofluorophosphate has a superior effect in dental care, so it is more commonly used in dental care products such as toothpaste.

At present, there are different toothpastes on the market, the common ones are: fluoride toothpaste, anti-inflammatory toothpaste and anti-allergy toothpaste, you can choose according to your own needs, maintain oral health, as long as you choose the toothpaste on the line. Here I believe that everyone knows how to choose toothpaste.

Preparation method

  1. Add a certain amount of water to a 1000mL beaker, add solid soda ash at room temperature, stir for 30 minutes to fully dissolve it, and then add chloroacetic acid for neutralization. The neutralization reaction of chloroacetic acid is exothermic, accompanied by the release of a large amount of carbon dioxide gas, the reaction is relatively drastic, in order to control the temperature of the neutralization reaction (the temperature is too high, the temperature is too high, the temperature is too high, the temperature is too high. Chloroacetic acid will undergo hydrolysis reaction to produce hydroxyl carboxylic acid) and prevent foam overflow during the reaction, the addition rate of chloroacetic acid is slow, and its dosage depends on the pH value of the solution; After the solution becomes clear, pour it into a three-port flask and put it into an electric heating water bath for heating reaction. When it reaches a certain temperature, add sodium thiosulfate crystal, stir and heat up to 85℃, and react at this temperature for 40 minutes to obtain salt. After the temperature continues to rise to 95℃, the strong alkali thioglycolating agent solution is added, the reaction is about 40min, the heating and stirring are stopped, the natural cooling is done, and the transparent sodium thioglycolate product can be obtained after purification.
  2. Add 185g sodium chloroacetate,29g isopropyl xanthoxanthate and appropriate amount of water into a 500ml four-mouth flask, react at 75℃ for 2h, then drop to room temperature, and slowly add 5% excess monoethylamine into the four-mouth flask with stirring. After the addition, the temperature is raised to 70℃ and the lh is kept warm. At this time, the reaction system changes from transparent to yellow cloudy, and finally becomes brown cloudy liquid. Stop stirring, stand stratification, the upper layer is yellow transparent liquid, which is ethylthiamine vinegar, said the mass is 77.1g, the purity is greater than 96%, the isopropyl alcohol mass fraction is less than 3.0%; The lower layer is dark red alkaline waste liquid, containing sodium leucyl acetate, sodium chloride, etc., which can be directly used as flotation agents.

Application

1. Application in the separation of copper and lead Sodium thioglycolate, as a non-toxic, small molecule inhibitor, has a good inhibition effect on chalcopyrite, and can be applied in the separation process of copper-lead mixed concentrate to achieve the separation of copper and lead. Factors such as the dedrug effect, the type and dosage of the collector, the pulp p and H value, and the amount of sodium thioglycolate during separation have important effects on the separation effect of copper and lead, but the amount of sodium thioglycolate is the most important influencing factor. When the amount is appropriate, the separation of copper and lead can be better achieved. When the amount is too large, sodium thioglycolate can inhibit both of them. Inhibition mechanism: The infrared spectral curves of sodium thioglycolate after the interaction with chalcopyrite and galena were bifurcated. After washing, the absorption valley of these characteristic groups became weak but did not disappear completely, which proved that sodium thioglycolate coexisted with physical adsorption and chemisorption on chalcopyrite and galena surface.

2. Activated sphalerite with copper sulfate in high pH slurry, lime as an inhibitor of pyrrhotite and pyrite, supplemented by sodium thioglycolate, can effectively achieve zinc-sulfur separation, industrial production test obtained grade 45.10% zinc concentrate, operation recovery of 94.39%. Sodium thioglycoacetate is a medium toxic agent, which has a good inhibition effect on pyrite and pyrrhotite, and can completely replace highly toxic cyanide to achieve cyanide-free separation process of zinc and sulfur, which not only ensures the production index of zinc concentrate grade and recovery rate, but also can meet the national environmental protection requirements. Sodium thioglycolate has little inhibitory effect on sphalerite, and has maintained good production index since the use of sodium thioglycolate.

At present, according to the needs of customers, we have opened a new production line, all using high-purity imported raw materials production, sodium thioglycolate widely used in hair removal (such as leather, human body), hair ironing and dyeing agent, solid and liquid media preparation.

Fluorine exists widely in nature and is one of the essential trace elements for human body, mainly accumulated in teeth and bones. Proper fluoride is necessary for the human body to maintain the normal development and calcification of teeth. The discovery that fluoride can prevent dental caries is arguably one of the greatest contributions of preventive oral medicine to mankind in the 20th century.

In short, fluoride ions can inhibit tooth demineralization, promote tooth mineralization, and enhance tooth resistance to acid; Fluoride also reduces the incidence of dental caries by affecting the metabolic activity of caries-causing bacteria. Therefore, moderate use of fluoride can effectively prevent tooth decay, which is the result of hundreds of clinical studies over decades. The commonly used fluoride in the mouth is sodium fluoride, sodium monofluorophosphate, stannous fluoride, etc., such as fluoride toothpaste, fluoride mouthwash, fluoride foam, etc.

The easiest and most common way to protect your teeth with fluoride is to brush your teeth twice a day with fluoride toothpaste. Many domestic and foreign authorities, such as the World Health Organization (WHO), the Chinese Dental Association have affirmed the role of fluoride toothpaste to prevent dental caries, but also clearly pointed out the safety and effectiveness of fluoride toothpaste.

What is the function of sodium monofluorophosphate?

Sodium Monofluorophosphate is widely used as toothpaste additive, concrete corrosion inhibitor, food, medical and so on.

1. Application in toothpaste

SMFP is the most widely used toothpaste additive in the world, and is an excellent anti-caries agent and tooth desensitization agent, with a mass fraction of 0.7% to 0.8% in toothpaste. There are two main categories according to the ingredients: care toothpaste and biological toothpaste.

Nursing toothpaste: nursing toothpaste has the functions of preventing caries, desensitizing, anti-inflammatory and preventing tooth stones, etc. The grass coral total effect nursing toothpaste developed has this multi-effect function. The most important thing for the effective prevention and treatment of dental and periodontal diseases is to eliminate bacteria harmful to dental health in the mouth, and herbal extracts have been widely recognized in preventing and eliminating general inflammation of the gum and oral mucosa. The fluoride in Grass coral Total effect care toothpaste has the function of antibacterial and bactericidal. According to relevant studies, low concentration of fluoride ions (0.8% sodium monofluorophosphate in grass coral) has a better antibacterial effect. Fluoride is used as an additive to prevent caries. It not only has a health care effect on acid-resistant desensitization of teeth, but also acts with tooth enamel to form fluorapatite on the surface of tooth enamel, which improves the hardness of tooth enamel.

2) Biological toothpaste: Biological toothpaste is the addition of toothpaste to the biological body has a specific active function of the substance, the current biological toothpaste mainly contains enzyme preparations, antibody preparations and other biological active preparations. The toothpaste containing enzyme preparation mainly contains protease and glucanase. Proteolytic enzyme toothpaste can promote the rapid hydrolysis and break of the long chain of protein polypeptides, make the food residue attached to the tooth surface soft, easy to clean the mouth, and has the function of softening blood vessels, can make the inflammation and edema of the gum subside, and the phenomenon of tooth bleeding has been significantly improved or eliminated.

Glucanase helps remove tartar. Toothpaste containing antibody preparation is generally divided into: toothpaste containing milk antibody and toothpaste containing genetically modified preparation. Milk antibody toothpaste is to extract antibodies from milk, and it is added to the toothpaste to fight against a certain disease. The toothpaste containing transgenic antibody preparation is to add the product of human oral disease vaccine gene in the transgenic horse bell tuber into the toothpaste, which can produce the corresponding effect of preventing oral diseases. The fluorine in sodium monofluorophosphate is stable, and the fluorine in one year is maintained at 84.4%, which effectively ensures the caries prevention effect. Its pH value is 5.5 ~ 6.5, which is neutral. And good compatibility with abrasives, these advantages determine that sodium monofluorophosphate is very suitable for toothpaste additives, has been in mass production in China. The anti-caries effect of fluoride toothpaste was observed in Beijing Stomatology Science Center for two and a half years, and the caries decreased by 42.95%.

2. Application in food

1) SMFP used as a food additive: From long-term clinical trials, it is known that sodium monofluorophosphate is better than other common fluoride raw materials (such as sodium fluoride) as a source of fluorine. Sodium monofluorophosphate can be used as a food additive to increase food nutrition, but if it exceeds the standard, it is unsafe. Sodium monofluorophosphate is added to foods, and 0.25 to 5mg of fluorine can be added every day, which is equivalent to the intake of 2.5 to 16mg sodium monofluorophosphate. According to the data, it is not safe to consume sodium fluoride (1.7 to 14mg) and phosphate (1.1 to 8.8mg) every day. In Europe, the amount of additives in food is generally below the maximum limit. For adults, eating 2mg of fluorine-containing food per day will not exceed the standard. Therefore, we should pay attention to the safety of sodium monofluorophosphate while enhancing the nutritional value of food.

2) SMFP used as chewing gum material: Chewing gum has always been favored by the public. But the current chewing gum does not have caries prevention, desensitization, bacteriostasis, anti-cold and other health functions. Although the average medicated toothpaste has one or more effects, it cannot replace the chewing function and taste of chewing gum. In 1998, Li Guohua developed a chewing gum with multiple effects, which added 0.5% sodium monofluorophosphate, so it has a good anti-caries effect.

3. Medical applications

1) SMFP used to regulate menopause: female lipid and lipoprotein metabolism Sodium monofluorophosphate can be used to regulate lipid and lipoprotein metabolism in postmenopausal women.

2) SMFP used to increase bone mass and alleviate osteoporosis: Sodium monofluorophosphate promotes osteoblast differentiation and diffusion while promoting bone mass increase, which is caused by fluorine inhibiting growth factors in acid phosphatase. MFP can perform its function through other signaling mechanisms. Although sodium fluoride also has the function of increasing bone mass, MFP increases bone mass more when consuming equal amounts of MFP and NaF. Sodium monofluorophosphate can increase bone mass and relieve osteoporosis, but it does not change the mineralization of bone tissue.

4. Used as a corrosion inhibitor:

When steel bars corrode, a series of protection and repair methods can strengthen the structure of concrete, and corrosion inhibitors are the most attractive alternatives. MFP as a rust inhibitor can slow down the corrosion of rebar.

Is sodium monofluorophosphate good for your teeth

In the past, due to the backward medical knowledge and limited conditions, people had little awareness of tooth protection, and many people did not understand why teeth should be protected. Teeth are the hardest organ in the human body. They are used to bite, bite and grind food, and help with pronunciation. The human front teeth have the effect of tearing food, and the back teeth have the effect of grinding food, and the food is conducive to the digestion and absorption of the stomach after being fully chewed. Therefore, if the teeth are not good, it is very likely to affect our gastrointestinal problems.

In addition, the teeth are not good, but also cause pain, as the saying goes: “toothache is not a disease, it really hurts”, because our teeth are densely covered with roots of the same dental nerves, pain through these dense small dental nerves transmission. Another point can not be ignored, bad teeth will also bring bad breath, serious people will affect interpersonal communication, so it is very important to protect teeth!

How can I keep my teeth and gums healthy?

It’s not hard to keep your mouth clean, healthy and consistent. Following a simple daily routine can help prevent most dental problems: use fluoride toothpaste, brush your teeth last thing at night and at least once during the day; Maintain a good diet, reduce the number of sugary foods and drinks you eat, and visit your dentist regularly.

Although most people brush their teeth regularly, some people do not go to the dentist for regular check-ups. A few small changes in your daily habits can make a big difference over time. A dental team can remove accumulated tartar and calculus from the teeth and treat existing gum disease. However, daily dental care is up to you, and the main weapons are your toothbrush and toothpaste.

How to choose the right toothpaste? Among anti-caries toothpastes, sodium fluoride and sodium monofluorophosphate are representative ingredients. There are also stannous fluoride and so on, which are used in fluoride toothpaste. As long as the fluoride content in the anti-caries toothpaste reaches 1/1000, it can effectively prevent caries. In the case of the same fluoride content, the anti-caries effect of the two components is theoretically similar, so from the point of view of caries prevention to choose, the two choices are the same. Judging from the whitening effect. Phosphate components can be combined with calcium ions in dental stones, which can effectively reduce the formation of dental stones, so as to achieve the effect of teeth whitening. Sodium monofluorophosphate is a little stronger at whitening teeth.

At present, in some supermarkets, most of the varieties of toothpaste are labeled as fluoride toothpaste or sodium monofluorophosphate in the active ingredient. So, is sodium monofluorophosphate good for your teeth?

Sodium monofluorophosphate (SMFP) is a chemical substance, white powder or white crystal, easily soluble in water, strong hygroscopic, at 25° water dissolution is no side effects and no corrosion. Sodium monofluorophosphate for toothpaste industry is used as an anti-caries agent, desensitization additive, and also used as a bactericide and preservative in toothpaste processing. The conventional content in toothpaste is 0.7-0.8%, and the conventional fluorine content in drinking water is 1.0mg/L. The aqueous solution of sodium monofluorophosphate has obvious bactericidal effect. It has obvious inhibitory effect on melanosomin, staphylococcus aureus, salmonella and so on.

Fluoride can be applied in a variety of ways in dentistry. In addition to fluorinated products for daily oral hygiene, such as toothpaste and mouthwash, there are special dental treatments available in the form of gels and varnishes, among others, at the dentist’s office. The most common way is to apply fluoride topically by brushing your teeth daily with fluoride toothpaste, which protects the enamel from bacteria in your mouth. It is important to use fluoride toothpaste in your daily brushing from childhood. In this way, teeth enjoy better health and protection throughout their lives, reducing the risk of tooth decay and other oral diseases.、

Over the years, the world has studied the anti-caries effect of sodium monofluorophosphate used in toothpaste and its toxicity to the human body, although after repeated research and many debates, the final conclusion is that sodium monofluorophosphate is safe for the human body in the anti-caries aspect and can be used with peace of mind.

What are the uses of hydrogenated rosin?

Hydrogenated rosin is often used as a plasticizer in the adhesive industry for hot melt, pressure sensitive, and rubber type adhesives

In the paint industry, such as automotive coatings prepared from deeply hydrogenated rosin as raw material

In the food industry, it can be used as a chewing gum matrix to ensure long-term storage without discoloration; Hydrogenated rosin can also be used to make fruit protective coatings.

In papermaking, hydrogenated rosin can be used to make high-grade paper with good water resistance and light resistance. In the pharmaceutical industry, hydrogenated rosin can be used as a tackifier for ointments.

In the cosmetics industry, hydrogenated rosin can be used as liquid lipstick; In shampoo, containing hydrogenated rosin can increase hair shine.

We are not unfamiliar with rosin, so what is the difference between hydrogenated rosin and rosin? How should we choose these two products? First, let’s take a look at the differences between them.

Differences in properties between hydrogenated rosin and rosin

Hydrogenated rosin, also known as demethylated rosin, is a product obtained by hydrogenation reaction of rosin after partial removal of methyl groups. Due to the increase of C-H bonds in hydrogenated rosin, this substance has better stability and high temperature resistance, and its melting point is also relatively higher. In contrast, ordinary rosin contains more methyl groups, making it prone to volatilization and producing irritating odors. Hydrogenated rosin has relatively no such problem.

Differences in the Use of Hydrogenated Rosin and Rosin

Due to its excellent properties and stability, hydrogenated rosin is widely used in fields such as inks, coatings, adhesives, and rubber. Rosin is mainly used in the production of daily necessities such as aromatherapy and pixels, as well as in the fields of traditional Chinese medicine and capsules in the pharmaceutical industry.

Differences in production methods between hydrogenated rosin and rosin

The production process of hydrogenated rosin requires the removal of methyl groups and hydrogenation reactions, while rosin production is obtained through steps such as extraction, distillation, and cooling of liquid rosin. Therefore, the production process of hydrogenated rosin is relatively complex.

In summary, although hydrogenated rosin and rosin are both products derived from pine resin, there are significant differences in their properties, uses, and production methods. In practical applications, people need to choose suitable products based on different needs.

Unilong is a high-quality manufacturer in China. Our hydrogenated rosin is one of the rosin modified products. While ensuring product quality, we are also committed to product innovation and providing you with the best products. Our service philosophy is that we are not only a manufacturer, but also your production partner.

Sodium Monofluorophosphate In Tooth Paste

Sodium Monofluorophosphate, also named as SMFP with CAS number 10163-15-2, is a fluorine-containing inorganic fine chemical, an excellent anti-caries agent and tooth desensitization agent. It is a kind of white odorless powder free from signs of impurity. It is easily soluble in water and highly hygroscopic. The purity of SMFP can reach 99%. The molecular formula is Na2PO3F and molecular weight is about 143.95. As a source of fluorine, it is safer than other fluoride raw materials (such as sodium fluoride).

Sodium monofluorophosphate is widely used in food additives, toothpaste, metal cleaners, special glass, skin care cosmetics and other fields. In the field of toothpaste, sodium monofluorophosphate is mainly used in the production of fluoride toothpaste. As a covalent fluoride, sodium monofluorophosphate aqueous solution has obvious bactericidal effect, and it has obvious inhibitory effect on Staphylococcus aureus, Salmonella, Aspergillus niger, etc. Sodium monofluorophosphate will be decomposed by acids or salivary enzymes in the oral cavity, releasing fluoride ions, which react with crystals on the surface of tooth enamel to form fluoroapatite, thereby enhancing tooth resistance and inhibiting caries.

Sodium monofluorophosphate is an excellent substitute for sodium fluoride. At present, sodium monofluorophosphate has basically replaced sodium fluoride in some toothpaste formulations. At the same time, sodium monofluorophosphate also has certain advantages in the competition with stannous fluoride.

Sodium Monofluorophosphate in Tooth paste

In recent years, as residents pay more attention to dental health, the market demand for fluoride-containing anti-caries toothpastes has increased, and the market demand for sodium monofluorophosphate has been released.

What is potassium iodide

Potassium iodide, a feed additive, is an ionic compound in which iodine ions can form a dark yellow precipitate of silver iodide with silver ions (see photo decomposition, which can be used to make high-speed photographic films). Therefore, silver nitrate can be used to test the presence of iodine ions. Iodine, as a component of thyroxine, is closely related to the basic metabolism of livestock and poultry, participating in almost all material metabolism processes. Iodine deficiency in livestock can cause thyroid hyperplasia and hypertrophy, decrease the basic metabolic rate, and affect growth and development. Iodine needs to be added to the feed of young livestock and livestock in iodine deficient areas. High yielding dairy cows and laying hens also require an increase in iodine, and iodine needs to be added to their feed.

What is the application of potassium iodide

Anti radiation effects: Various countries will distribute or reserve iodine tablets to residents around nuclear power plants, the main component of which is potassium iodide. In the event of radiation leakage from nuclear power plants due to disasters, allowing surrounding residents to take iodine tablets can saturate iodine in the thyroid and reduce the absorption of radioactive Chemicalbook iodine 131 by the thyroid. However, it is necessary to take it within 4 hours when exposed to free iodine radiation to have an effect, and it cannot prevent free radiation and isotopes other than iodine-131. Improper use by ordinary people without instructions can cause symptoms of hyperthyroidism.

What is Potassium Iodide

Potassium iodide is a raw material for manufacturing iodides and dyes. Used as a photosensitive emulsifier for photography. In medicine, it is used as an expectorant, diuretic, goiter prevention and treatment agent, as well as a pre operative medication for hyperthyroidism. It is also used in the production of rheumatic painkillers with analgesic and blood activating effects. It is a co solvent for iodine and certain insoluble metal iodides.

What are UV absorbers

Ultraviolet absorber is a light stabilizer that can absorb the ultraviolet part of sunlight and fluorescent light sources without changing itself. Ultraviolet absorber is mostly white crystalline powder, good thermal stability, good chemical stability, colorless, non-toxic, odorless, generally used in polymers (plastics, etc.), coatings and so on.

Most colorants, especially inorganic pigment colorants, can play a certain degree of light stabilization when used alone in plastic products. For colored plastic products for long-term outdoor use, the light stability of the product cannot be improved by the colorant alone. Only the use of light stabilizer can effectively inhibit or slow down the light aging rate of colored plastic products for a long time. Significantly improve the light stability of colored plastic products. Hindered amine light stabilizer (HALS) is a class of organic amine compounds with steric hindrance effect. Due to its functions of decomposing hydroperoxide, quenching radical oxygen, trapping free radicals, and recycling of effective groups, HALS is the plastic light stabilizer with high anti-photoaging efficiency and the largest amount at home and abroad. The data show that the appropriate light stabilizer or the appropriate combination system of antioxidant and light stabilizer can improve the light and oxygen stability of outdoor colored plastic products several times. For plastic products colored by photoactive and photosensitive colorants (such as cadmium yellow, uncored rutile, etc.), considering the catalytic photoaging effect of the colorant, the amount of light stabilizer should be increased accordingly.

uv-absorbers

Uv absorbers can generally be classified according to chemical structure, action fraction and use, which are described below:

1.Classification according to chemical structure: ultraviolet absorbers can be divided into organic ultraviolet absorbers and inorganic ultraviolet absorbers. Organic ultraviolet absorbers mainly include benzoates, benzotriazole, cyanoacrylate, etc., while inorganic ultraviolet absorbers mainly include zinc oxide, iron oxide, titanium dioxide and so on.

2.Classification according to the mode of action: ultraviolet absorber can be divided into shielding type and absorption type. Shielding UV absorbers are able to reflect UV light and thus prevent it from entering the body, while absorbing UV absorbers are able to absorb UV light and convert it into heat or visible light.

3.Classification according to use: ultraviolet absorbent can be divided into cosmetic grade, food grade, pharmaceutical grade, etc. Cosmetic grade UV absorbers are mainly used in sunscreen, skin care products and other cosmetics, food grade UV absorbers are mainly used in food packaging materials, and pharmaceutical grade UV absorbers are mainly used in drugs.

Do you know about photoinitiator

What are photoinitiators and how much do you know about photoinitiators? Photoinitiators are a type of compound that can absorb energy at a certain wavelength in the ultraviolet (250-420nm) or visible (400-800nm) region, generate free radicals, cations, etc., and thus initiate monomer polymerization, crosslinking, and curing. However, the wavelengths absorbed by different photoinitiators are different.

The classification of photoinitiators can be mainly divided into two categories: free radicals and ionic types. Free radicals can be divided into Type I and Type II; Ionic types can be divided into cationic and anionic types. The photoinitiator is the starting point of the formulation, and its final use is influenced by performance requirements and the formulation system. There is only the most suitable photoinitiator, there is no best photoinitiator.

Photoinitiators are located upstream in the industrial chain. The raw materials in the UV curing industry chain are mainly basic chemical materials and specialized chemicals, with photoinitiators located upstream of the industry chain. The series of thiol compounds can be used as raw materials for photoinitiators, and are mainly used in the fields of medicine and pesticide manufacturing; Photoinitiators are applied in various fields such as photoresists and supporting chemicals, UV coatings, UV inks, etc., with terminal applications spanning electronic products, home decoration and building materials, medicine and medical treatment, etc.

There are various types of photoinitiators with a wide range of uses, so how should we choose them? Next, let me tell you how to choose several commonly encountered products.

Firstly, I would like to introduce photoinitiator 819, which can be used for colored UV cured plastic coatings. UV coatings, due to their excellent performance and efficient production, have been widely used on plastic shells of various electronic and household appliances products. However, the deep solidification of UV coatings after coloring is not good, resulting in poor film adhesion and poor dispersion and arrangement of pigments by UV resins, seriously affecting the appearance of the coatings, Therefore, the traditional construction process is to first apply solvent based colored primer for coloring, then apply UV varnish after baking to improve the various physical properties of the paint film surface.

Photoinitiator 184 is an efficient and yellowing resistant free radical (I) type solid photoinitiator with the advantages of long storage time, high initiation efficiency, and wide UV absorption range. It is mainly used for UV curing of unsaturated prepolymers (such as acrylic esters) together with single or multi functional vinyl monomers and oligomers, and is particularly suitable for coatings and inks that require high yellowing degree.

Photoinitiator TPO-L is a kind of liquid photoinitiator, which is used in the formulation system with low yellowness and low odor. It is commonly used in silk screen printing ink, Planographic printing printing ink, flexographic printing ink, photoresist, varnish, printing plate and other fields.

The photoinitiator TPO is mostly used in white systems, and can be used in UV curing coatings, printing inks, UV curing adhesives, Optical fiber coatings, photoresists, photopolymerization plates, stereolithographic resins, composites, tooth fillers, etc.

Photoinitiator 2959 is an efficient non yellowing photoinitiator with high activity, low odor, non yellowing, low volatility, insensitivity to oxygen polymerization, and high surface curing efficiency. Unique hydroxyl groups that are easily soluble in water-based coatings. Especially suitable for water-based acrylic esters and unsaturated polyesters. Photoinitiator 2959 is also an adhesive approved by the FDA certification system for non direct contact with food.

Benzophenone is a free radical photoinitiator mainly used in free radical UV curing systems such as coatings, inks, adhesives, etc. It is also an intermediate in organic pigments, pharmaceuticals, spices, and insecticides. This product is also a styrene polymerization inhibitor and fragrance fixative, which can give fragrance a sweet flavor, and is widely used in perfume and soap essence.

Products similar to photoinitiators are ultraviolet absorbers. Sometimes, people often cannot distinguish between the two. UV absorbers can replace photoinitiators. Because UV absorbers are the most widely used type of light stabilizer and can be compatible with or replace photoinitiators for use, and their effectiveness is also very good. Photoinitiators are specifically used for photocuring, for inks, coatings, and can also be used in industrial and electronic fields. UV absorbers have a relatively large range of uses, mainly used in cosmetics with high quality requirements. Meanwhile, the price of ultraviolet absorbers is relatively high, while photoinitiators are relatively low. You can choose corresponding products based on your own needs.

We are a professional initiator manufacturer. In addition to the products mentioned above, we also have the following similar products:

What Is Polyvinylpyrrolidone (PVP)

Polyvinylpyrrolidone is also called PVP, CAS number is 9003-39-8. PVP is a completely synthetic water-soluble polymer compound that is polymerized from N-vinylpyrrolidone (NVP) under certain conditions. At the same time, PVP has excellent solubility, chemical stability, film-forming ability, low toxicity, physiological inertness, water absorption and moisturizing ability, bonding ability, and protective adhesive effect. It can combine with many inorganic and organic compounds as additives, additives, auxiliary materials, etc.

Polyvinylpyrrolidone (PVP) has traditionally been used in various fields such as medicine, cosmetics, food and beverage, brewing, textiles, separation membranes, etc. With the development of new scientific and technological products, PVP has been applied in such high-tech fields as photo curing resins, Optical fiber, laser discs, drag reducing materials, etc. PVP with different purities can be divided into four grades: pharmaceutical grade, daily chemical grade, food grade, and industrial grade.

The main reason why PVP can be used as a co precipitant is that the ligands in PVP molecules can combine with the active hydrogen in insoluble molecules. On the one hand, relatively small molecules become amorphous and enter PVP macromolecules. On the other hand, hydrogen bonding does not change the water solubility of PVP, so the result is that insoluble molecules are dispersed in pVp macromolecules through hydrogen bonding, making them easy to dissolve. There are many types of PVP, How do we choose that model when choosing. When the amount (mass) of PVP is the same, the increase in solubility decreases in the order of PVP K15>PVP K30>PVP K90. This is because the solubilization effect of PVP itself changes in the order of PVP K15>PVP K30>PVP K90. Generally, pVp K 15 is more commonly used.

About the generation of PVP: only NVP, a monomer, participates in the polymerization, and its product is Polyvinylpyrrolidone (PVP). The NVP monomer undergoes self crosslinking reaction or the NVP monomer undergoes cross-linking copolymerization reaction with the crosslinking agent (containing multiple unsaturated group compounds), and its product is Polyvinylpyrrolidone (PVPP). It can be seen that various polymerization products can be produced by controlling different polymerization process conditions.

We understand the process flow of PVP:

Application of industrial grade PVP: PVP-K series can be used as film agent, thickener, lubricant and adhesive in daily chemical industry, and can be used for eruption, Moss, hair fixative gel, hair fixative, etc. Adding PVP to hair dyes and modifiers for skin care, foam stabilizers for shampoos, dispersants and affinity agents for wave styling agents, and to cream and sunscreen can enhance the wetting and lubricating effect. Secondly, adding PVP to the detergent has a good anti color effect and can enhance the cleaning ability.

Application of PVP in industrial and high-tech fields: PVP can be used as a surface coating agent, dispersant, thickener, and adhesive in pigments, printing inks, textiles, printing and dyeing, and color picture tubes. PVP can improve the bonding performance of the adhesive to metal, glass, plastic and other materials. In addition, PVP is increasingly widely used in separation membranes, ultrafiltration membranes, microfiltration membranes, nanofiltration membranes, oil exploration, photo curing resins, paints and coatings, Optical fiber, laser discs and other emerging high-tech fields.

Application of medicinal grade PVP: Among the PVP-K series, k30 is one of the synthetic excipients used, mainly for production agents, adhesive agents for granules, sustained-release agents, adjuvants and stabilizers for injections, flow aids, dispersants for liquid formulations and chromophores, stabilizers for enzymes and thermosensitive drugs, co precipitants for difficult to tolerate drugs, extenders for ophthalmic lubricants, and coating film-forming agents.

Polyvinylpyrrolidone and its polymers, as new fine chemical materials, are widely used in medicine, food, daily chemicals, printing and dyeing, pigment coatings, biological materials, water treatment materials and other fields, with broad market application prospects. After years of continuous exploration, we have developed various aggregation products, including the following:

Product Name CAS No.

In short, the PVP series of products have excellent performance and are widely used as polymer additives in medicine, coatings, pigments, resins, fiber inks, adhesives, detergents, textile printing and dyeing. PVP, as a polymer surfactant, can be used as a dispersant, emulsifier, thickener, leveling agent, viscosity regulator, anti reproduction liquid agent, coagulant, cosolvent, and detergent in different dispersion systems.

Do You Know About Biodegradable Materials PLA

“Low carbon living” has become a mainstream topic in the new era. In recent years, green environmental protection, energy conservation, and emission reduction have gradually entered the public’s vision, and have also become a new trend advocated and increasingly popular in society. In the green and low-carbon era, the use of biodegradable products is considered an important symbol of low-carbon life, and is widely respected and disseminated.

With the acceleration of the pace of life, disposable foam plastic lunch boxes, plastic bags, chopsticks, water cups and other items have become ubiquitous in life. Different from paper, cloth and other materials, plastic products are discarded in nature and difficult to be degraded. While bringing convenience to people’s lives, excessive use can also cause “white pollution”. In this context, biodegradable biomaterials have emerged. Biodegradable materials are an emerging material that has significant advantages in terms of environmental performance compared to traditional disposable plastic products. Products manufactured using biodegradable biomaterials as raw materials have a huge market space and become an important carrier of the fashionable low-carbon lifestyle concept.

Do You Know About Biodegradable Materials PLA

There are many types of biodegradable materials, including PCL, PBS, PBAT, PBSA, PHA, PLGA, PLA, etc. Today we will focus on the emerging biodegradable material PLA.

What is PLA?

PLA, also known as polylactic acid, is a starch raw material that is fermented to produce lactic acid, which is then converted into polylactic acid through chemical synthesis and has good biodegradability. After use, it can be completely degraded by microorganisms in nature, ultimately producing carbon dioxide and water without polluting the environment. The environment is very favorable, and PLA is recognized as an environmentally friendly material with excellent biological properties.

The main raw materials of PLA are renewable plant fibers, corn and other agricultural and sideline products, and PLA is an important branch of biodegradable emerging materials. PLA has unique properties in terms of hardness and transparency. It has strong biocompatibility, wide application range, strong physical and mechanical properties, and meets various usage requirements. It can be used in various methods for large-scale production, with an antibacterial rate of 99.9%, making it the most promising degradable material.

Application of PLA

Polylactic acid (PLA) is a new environmentally friendly and green biodegradable material produced from lactic acid as raw material; In recent years, PLA has been applied to products and fields such as straws, tableware, film packaging materials, fibers, fabrics, 3D printing materials, etc. It also has great development potential in fields such as medical auxiliary equipment, automotive parts, agriculture, forestry, and environmental protection.

Do you know that 1-Methylcyclopene can keep fresh

July is the peak of summer, and during hot and humid summers, food can become a fertile medium for bacteria at any time. Especially fruits and vegetables, if newly purchased fruits and vegetables are not stored in the refrigerator, they can only be stored for one day. And every summer, there are many cases of diarrhea caused by “eating poorly”, both adults and children, often mistaken for eating too “cold”. In fact, low-temperature food or beverages do indeed cause some friends to have faster intestinal peristalsis, but generally do not cause people to run to the restroom several times a day. So at this point, the first thing to consider is the intestinal infection caused by food hygiene. Is the food that is consumed rotting and spoiling? So how can we eat fresh fruits and vegetables in the hot summer?

Do you know that 1-Methylcyclopene can keep fresh

At this point, the first thing we think of is refrigerator storage. However, there are many kinds of food and drinks stored in refrigerators, among which there are many foods that “inject bacteria” into refrigerators, such as eggs that may carry salmonella, and raw meat, fruits and vegetables that may carry pathogenic Escherichia coli, pathogenic Staphylococcus aureus and parasites. And the refrigerator also has a shelf life for preservation. Generally, food that takes 2-3 days must be eaten, otherwise it will rot in the refrigerator over time. At the same time, the refrigerator also has a certain amount of storage space, which is only used for household use. If it is a large supermarket, how do we keep the food fresh from the source merchants we purchase?

With the development of economic globalization, the import and export of fruits and vegetables has become the norm. In the face of this situation, we have to study a new type of preservative- -1-MCP fruit and vegetable preservative. Once the product was developed, it received a high response. Because this is a non-toxic, highly safe, and significantly effective preservative. Next, let’s talk about the ingredients of 1-MCP fruit and vegetable preservative.

Do you know that 1-Methylcyclopene can keep fresh

What is 1-Methylcyclopropene?

1-Methylcyclopropene, abbreviated as 1-MCP in English, CAS 3100-04-7 chemical formula is C4H6. Under normal temperature and pressure, the appearance is colorless gas, non-toxic and tasteless, with a density of 0.838g/cm3. It is a very active Cyclopropene compound. 1-Methyl Cyclopropene is mainly used as a plant growth regulator and is widely used in the field of plant preservation. It has the advantages of low consumption, good preservation effect and high safety.

Characteristics of 1-MCP

1-MCP can inhibit the release of ethylene by plants themselves, and also block the binding of ethylene to related receptors in plant cells, thereby inhibiting the ripening effect of ethylene. Therefore, the application of 1-Methylcyclopene can effectively prolong the maturation and aging process of plants, thereby prolonging their shelf life, reducing corruption and waste during transportation and storage, and extending the shelf life of goods.

Applications of 1-MCP

1-MCP can be applied to the preservation of fruits, vegetables, and flowers to prevent plant wilting. For example, when applied to fruits and vegetables such as apples, pears, plums, kiwifruit, and tomatoes, it can delay their ripening, reduce water evaporation, and maintain their hardness, taste, and nutritional composition; In terms of flower preservation, it can maintain the color and fragrance of the flowers. In addition, 1-Methylcyclopene can also improve plant disease resistance. 1-Methylcyclopene is a new milestone in fruit and vegetable preservation after modified atmosphere preservation.

After the epidemic, the economy recovered, and the development of global trade was gradually expanding. Every year, each country would produce a large number of local fresh fruits and vegetables. Due to the imperfect development of agricultural cold chain logistics, about 85% of fruits and vegetables used ordinary logistics, resulting in a large number of decay losses, which also provided a broad market space for the promotion and application of 1-methyl Cyclopropene. Therefore, it can be seen that 1-MCP has broad development prospects, not only for various respiratory climacteric fruits and vegetables, but also can effectively extend post harvest storage and shelf life, especially for ethylene sensitive fruits and vegetables, and can maintain the original quality of fruits and vegetables for a long time.

What Is Squalane?

Many beauty enthusiasts spend a lot of time and energy on skin management, but the effect is minimal, and there are still various skin problems, deeply troubled by problematic muscles. Especially for girls, regardless of age, it is human nature to love beauty. Why do you do enough hydration work for your skin every day, or do you get dry and shaky? Why is the skin constantly prone to acne, which persists for a long time? Why do oil and long spots often accompany skin travel? Next, I would like to share —Squalane, a common ingredient in skin care products, and I hope it will be helpful to you.

What is Squalane?

Squalane CAS 111-01-3 is a colorless liquid. Most of them are found in shark Cod liver oil, which is made from squalene through hydrogenation, and a few of them are from olive oil and human fat. The predecessor of Squalane is squalene, but it does not have the antioxidant capacity of squalene, nor can it be converted into squalene on the skin, which does not stimulate and sensitize the skin. Squalane is a stable, well absorbed oil that can moisturize the skin and has good affinity for the skin. It is a very safe cosmetic raw material.

Squalane is a component in many skin care products, which has the function of beauty and skin care, such as relieving dry skin, softening skin, protecting skin, delaying skin aging, and improving Melasma.

  1. Relieve dry skin

Squalane is an inherent ingredient in the skin, which can alleviate dry skin, nourish skin, and have a good moisturizing effect.

  1. Make the skin soft

Squalane has good permeability and can enter into the skin, becoming softer, more tender and younger.

  1. Protecting the skin

Squalane will form a protective film on the skin surface, which has the effect of water locking. Especially suitable in dry and windy seasons to avoid skin damage from the external environment.

  1. Delaying skin aging

Squalane can inhibit skin Lipid peroxidation, promote the proliferation of skin basal cells, and alleviate skin aging.

  1. Improve Melasma

With the growth of age, many women have Melasma on their faces. Skin care products containing Squalane can be used, because the shark pattern has the effect of reducing melasma.

What are the characteristics of Squalane?

Squalane is a kind of stable, skin friendly, soft, mild and active high-end natural oil. Its appearance is colorless transparent liquid with high chemical stability. Squalane is rich in texture and non greasy after dispersed application. Squalane is a kind of oil with excellent sense of use. Due to its good permeability and cleansing effect on the skin, it is widely used in the cosmetics industry.

Squalane is a natural component of sebum, which can be considered as bionic sebum and can help other active ingredients penetrate; Squalane plays a crucial role in skin barrier repair.

Squalane is extremely mild because of its stability and high purity, less impurities in the product, and it is a part of the skin. It can be applied to sensitive skin and baby skin without causing acne. It has no sticky feeling during and after application, and has a soft cushion after absorption, improving the softness and moisturizing feeling of the skin.

Squalane is a saturated alkane. Under high temperature and ultraviolet radiation, it will not be rancid like vegetable oil. It is stable at -30 ℃ -200 ℃ and can be used in thermoplastic products such as lipstick. Squalane can be used in hair care products to increase brightness and alienation; Not irritating to the skin, not allergenic, very safe, especially suitable for baby care products.

Although there is only one word difference between Squalane and squalene, Squalane has more advantages, with good skin affinity, permeability and moisturizing effect. But don’t blindly deify the efficacy of Squalane. When buying skin care products containing Squalane, you should consider the cost performance ratio. Squalane is not recommended to buy products with inflated prices.

What is EDTA?

Ethylenediaminetetraacetic acid (EDTA) is an important complexing agent. It is a hexadentate ligand that can chelate various metal ions. Its four acid and two amine parts can be used as the teeth of ligand to form Chelation with manganese (II), copper (II), iron (III), cobalt (II) and other metal ions.

EDTA has extensive coordination properties and can form stable Chelation with almost all metal ions. EDTA is a large family that includes EDTA acid, Ca, Fe, Mg, Na, Zn, etc. It can be seen that the EDTA series has a wide range of uses, and EDTA can be applied to compounds widely used in personal care, skin care, processed foods, cosmetics, and cleaning products. EDTA also has a wide range of medical, engineering, agricultural, and industrial applications. Below, let me give you a specific explanation about the application of EDTA in various fields.

Application of EDTA in the field of daily chemicals

In cosmetics, personal care, and skin care products, EDTA is the main chelating agent (binding free metal ions), preservative, stabilizer, and purifying agent, which can maintain the formula free of metal ions and residues from tap water. It helps to reduce the hardness (mineral content) of tap water, so that other active ingredients in the formula, such as shampoo or shower gel, can function more effectively. EDTA also contributes to the local penetration of Active ingredient in skin care, thereby increasing the serum level of beneficial chemicals.

The Application of EDTA in the Food Industry

EDTA is commonly used as a preservative, stabilizer, and protection against discoloration and oxidation in food and beverages. Please note that the purity of food grade EDTA must be above 99%. It is a widely approved food additive (such as the FDA in the United States), an antioxidant and quality improver, and has functions such as preventing oil oxidation, food browning, and emulsified food.

EDTA Application
The Application of EDTA in the Medical Field

EDTA is used to treat mercury and other heavy metal poisoning through chelation therapy. Similarly, it can remove excess iron and calcium from the body. In medical applications related to blood, EDTA optimizes repeated blood transfusion and is an effective Anticoagulant, which can prevent blood samples from clotting and cell samples from caking. This is particularly important in clinical blood testing and cell analysis. EDTA is also used as a preservative for eye drops, as a decalcifying agent and preparation agent in oral surgery and dentistry, and as an anti plaque agent in arteries.

The Application of EDTA in the Industrial Field

EDTA is the main chelating agent for removing free metal ions. Almost all of its uses for human beings come from this single attribute. In the laundry industry, this means removing impurities from hard water. In the Textile manufacturing, EDTA can prevent free metal ions and impurities from fading dyed fabrics. In the paper industry, EDTA contributes to the effectiveness of pulp bleaching and purification processes. EDTA can also remove residual residue and scale on industrial equipment such as broilers that operate at high temperatures. In laundry products and cleaning agents, EDTA can soften hard water and improve the bleaching and cleaning performance of non chlorine cleaning agents.

The Application of EDTA in Agriculture

As is well known, fertilizer is an indispensable nutrient in the cultivation of crops. And many fertilizers indicate that they are “chelating Hefei”. So what are the advantages of chelating Hefei? Chelated fertilizers have been proven through experiments to effectively enhance crops’ resistance to drought, high temperature, low temperature, and salt alkali, as well as their lodging resistance. At the same time, chelated trace element fertilizers are not easily fixed in soil, soluble in water, and do not dissociate, and can be well absorbed and utilized by plants. EDTA is a chelating agent. As a trace element nutrient, EDTA is used in agriculture, forestry, animal husbandry or other cash crop.

We are a company that integrates research, development, production, and sales. We produce a series of EDTA products, with the main products as follows:

Production Name CAS No.
EDTA ACID 60-00-4

HEDTA-Fe 17084-02-5
EDDHA-FeNa 16455-61-1

Overall, EDTA is widely used and plays a crucial role in the development of various fields. I believe that there will be better and more favorable chelating agents to replace EDTA in the future, but currently, EDTA is irreplaceable.

What is PLA

In recent years, with the increasing awareness of environmental protection, people’s pursuit of goals has also changed. Nowadays, most people prefer to use safe, green, and pollution-free renewable bio based materials to replace traditional petroleum based materials. Among them, polylactic acid is widely used, which is basically ubiquitous. In our daily lives, shopping bags, paper cups, lunch boxes, straws, and so on in supermarkets. Below, let’s talk about the knowledge of polylactic acid.

What is PLA?

PLA, also known as Polyactive Acid, is a polymer material synthesized from lactic acid produced by corn fermentation. It has excellent biodegradability and is suitable for products and fields such as straws, tableware, film packaging materials, fibers, fabrics, 3D printing materials, etc. It also has great development potential in fields such as medical auxiliary materials, automotive parts, agriculture, forestry, and environmental protection. Due to its biodegradability, it also has a profound impact on environmental protection.

what is pla

The traditional methods of plastic disposal mainly include recycling, landfill, and incineration. Among them, repeated recycling leads to a decrease in the performance of plastics, while landfill and incineration inevitably lead to various long-term and deep-seated environmental problems. After being discarded, polylactic acid products can not only undergo composting and degradation treatment, but also be suitable for other traditional solid waste treatment methods. Composting refers to the process of organic decomposition of garbage under artificially controlled conditions through the biochemical action of microorganisms. Compared to other methods of garbage treatment, composting has the advantages of green and environmental protection. After the disposal of our sound field’s polylactic acid products, they can be 100% degraded by microorganisms, generating carbon dioxide and water to return to nature.

However, the biodegradability of PLA is not unconditional. The biodegradation of PLA requires two basic conditions: a humidity of 50% -60% and a temperature of 50-70 degrees Celsius. Under these conditions, microorganisms are likely to undergo months or even longer to gradually decompose PLA.

In addition to PLA, we can also provide biodegradable PBAT PBS PBSA PBST

what is PLA

Polylactic acid originates from the natural and fully soluble properties, driving the formation of a regeneration cycle system for biomass resources; From the perspective of raw materials, PLA’s raw materials are lactic acid fermented from sugar extracted from crops such as corn, sugarcane, and sugar beets through deep processing; From the perspective of product disposal. PLA products can be degraded into carbon dioxide and water, and participate in biological regeneration and cycling processes again through crop photosynthesis. The entire process from production to degradation of PLA fully demonstrates that PLA originates from nature and belongs to nature.

At the same time, polylactic acid has good biocompatibility and degradability, making it a crystalline thermoplastic material with relatively high thermal stability. Suitable for injection molding, extrusion, spinning and other processing processes, the processed products can be widely used in various fields such as home furnishings, tableware, packaging, clothing, agriculture, electronic products, etc. It can be seen that PLA degradable plastics will be a development trend in the future. If you would like to learn more information, please contact us.

What is a biodegradable material

In daily life, plastic products are almost everywhere, including shopping bags in supermarkets, disposable tableware, straws, and disposable ordinary plastic cups, all of which are closely related to us. With the increasing awareness of environmental protection among people, plastic products made from materials such as polyethylene or polypropylene are not easily decomposed and have a significant impact on the environment. Therefore, a biodegradable material product has been studied to replace them. So, what is biodegradable material? Which products are biodegradable materials? Let’s talk about specific issues related to biodegradable materials.

What is a biodegradable material?

Biodegradable materials are actually easy to understand. Biodegradable materials belong to polymer materials, which generally refer to a type of material that can degrade itself in a short period of time under natural conditions, which is commonly referred to as biodegradable materials. The key point to note is that the production materials of biodegradable materials come from natural plants, do not contain chemical components, and are harmless to the human body and environment.

What is a Carbomer

How much do you know about Carbomer?

Through the above description, we understand that carbomer has a wide range of uses, not only in the field of cosmetics, but also plays an important role in the field of medicine and epidemic prevention

As is well known, since 2020, antivirus and bactericidal products have been widely used, especially for hand cleaning, which has led to a significant increase in the demand for hand sanitizers. As one of the main components of free hand sanitizers, carbomer also caused a stir at that time, and even ran out of stock.

Carbomer

How much do you know about the different types and applications of Carbomer?

In addition to being able to apply to hand sanitizers for sterilization and disinfection, what other fields can Carbomer be applied to?

1.Thickening. It can generate a wide range of viscosity and fluidity.
2.Suspension. Capable of permanently suspending insoluble components in the system;
3.Emulsification. It can play an emulsifying and stabilizing role in the oil or water phase.

According to the different functions of carbomer, carbomer is divided into several main models. For example, the carbomer 940 model is characterized by its ability to produce high viscosity permanent emulsions and colloids produced by suspensions, good transparency, and short flowability; The characteristics of the carbomer 934 type are good thickening effect, strong shear resistance, permanent stability at high viscosity, and long-term fluidity in aqueous solution, making it very suitable for use in cream cosmetics; carbomer 941 has an efficient thickening effect and can be used to try clear and transparent water or alcohol. There are various types of Carbomer models, and we won’t list them here.

At present, our factory has upgraded carbomer 940 to carbomer 980.

In order to be safer, we use cyclohexane to make Carbomer 980, so that our product ingredients will be safer and the effect will be better.

Of course, Carbomer 980 is the same as Carbomer 940 in terms of viscosity and light transmittance.

If you have no special requirements on light transmittance and viscosity, we also recommend Carbomer 680, the price will be cheaper.

Next, we will understand the medicinal uses of carbomer: firstly, it is used as a controlled release drug made of sustained-release materials for application; Second, it can be used as a topical drug formula and carrier matrix to make ointment, suppository, cream, gel, lotion, etc; Third, the bioadhesive patch made of its gel, adhesiveness and film-forming properties is used as the carrier matrix and drug in the bioadhesive, which improves the bioavailability of the drug due to its long retention time in the tissue mucosa; Fourthly, by utilizing its suspension ability, it can effectively suspend insoluble components to form a uniformly dispersed system. When applied to oral suspensions, it is safe and effective, odorless, stable, and improves bioavailability.

How to Protect Skin in Summer

With the arrival of summer, more and more people are paying attention to their skin, especially female friends. Due to excessive sweating and strong oil secretion in summer, combined with strong ultraviolet rays from the sun, it is easy for the skin to sunburn, accelerate skin aging and pigment deposition, and in severe cases, even develop spots. Therefore, summer skincare is particularly important. This article starts from three aspects: sun protection, cleaning, and moisturizing, and introduces how we should take care of our skin in summer?

Sunscreen

Sunscreen is one of the essential steps in summer. Generally speaking, it is widely believed that sunscreen is to prevent sunburn. In fact, preventing sunburn is only a superficial phenomenon, and it is to help us prevent skin aging, pigmentation, skin diseases, etc. Therefore, using sunscreen skincare products in summer is essential. When choosing sunscreen products, it is best to choose sunscreen with an SPF value greater than 30. During use, attention should be paid to the completeness and uniformity of the application to achieve better results.

Cleaning

In summer, everyone knows that sweat and oil are secreted vigorously, and the body is prone to sweating and acne. Therefore, the cleaning steps in summer are also crucial, especially after applying sunscreen products, it is important to clean and repair before going to bed.

The correct method is: 1. Before cleaning the face, you need to wash your hands to remove bacteria. 2. When cleaning, you need to wash your face with warm water, as the temperature of the water can affect the skin’s water and oil balance. 3. If you are applying makeup. Make up removal must not be omitted, and after cleaning, use toner facial mask to repair. 4. According to different skin types, choose your own cleaning products. Mild facial cleanser is more suitable for summer.

Moisture

The high temperature in summer will lead to water evaporation, and the skin is more prone to water shortage. Proper hydration can help the skin maintain water oil balance. It is recommended to use spray moisturizing or moisturizing facial mask. To choose a moisturizer that is suitable for oneself, it is necessary to identify the skin type and issues, as well as the skin needs after cleansing, in order to be more effective in moisturizing.

However, how to choose cosmetics that are suitable for oneself has become a challenge for most girls. In stores, we often see many girls feeling distressed, and there are also many sales guides promoting their products. What ingredients of cosmetics do we choose that are beneficial for our skin? We all know that herbaceous plants are pure natural and non irritating Faced with increasingly healthy lifestyle habits, experts have developed the application of corresponding ingredients extracted from herbaceous plants in whitening and anti-aging cosmetics. The ingredients of plant extracts are more gentle and efficient than those synthesized by chemical synthesis. Below, we will introduce what plant extracts are.

What is a plant extract?

Plant extracts refer to substances extracted or processed from plants (all or a part of them) using appropriate solvents or methods, and can be used in the pharmaceutical, food, daily chemical, and other industries.

Why choose plant extracts?

With the improvement of living standards, people are increasingly resistant to chemically synthesized products, and more people are pursuing more gentle and efficient skincare. Therefore, plant active substances have become increasingly important. Experts have conducted experiments on some plant extracts. They are not only powerful in basic functions (whitening, anti-aging, anti-oxidation), but also may have additional functions such as soothing and repairing. As long as they are well purified, formula stability and other processes, they are really no inferior to chemical components! One of the most typical examples is the glabridin from liquorice.

In recent years, with the increasing attention paid to natural plant extraction, the market demand for plant extracts may experience significant growth. In response to this phenomenon, our company’s R&D department has developed a series of functional plant extract products:

As long as mild and non irritating herbal skincare products are used regularly, and attention is paid to daily care and diet, the optimal skin condition can be guaranteed.

How ECO Friendly Is PLA?

The environment provides necessary resources and conditions for our livelihood and development. With the development of society and the improvement of people’s awareness, protecting the environment has become a common goal for everyone.

In recent years, issues such as “white pollution” and “microplastics” have received widespread attention from society, and the main reason for this problem is mainly due to the widespread use of plastic products. Most of the plastic products used in daily life are petroleum based plastics that are difficult to degrade. Due to their non degradable materials, they have brought a burden to our natural environment, and their pollution control is also a global problem!

However, plastic products are ubiquitous in our lives, and therefore, biodegradable plastics are gradually becoming a new trend. Scientists have proposed a new concept of ‘originating from nature and returning to nature’. Developed biodegradable polylactic acid (PLA) through the conversion of corn and other grains This plastic, which is converted from plant starch, has excellent biodegradability and is environmentally friendly due to its preparation process that eliminates environmentally friendly petrochemical raw materials.

What is polylactic acid?

Polylactic acid, abbreviated as PLA, also known as polylactide, CAS number (26023-30-3/26100-51-6), is mainly produced by plant fermentation. Its main components include renewable resources such as corn and wheat, so polylactic acid has good biocompatibility and biodegradability. Waste polylactic acid can be decomposed into CO2 and H20 under microbial action or composting conditions. There is no pollution to the air and soil, and it is also beneficial for promoting the light and function of plants. Polylactic acid (PLA), as a biodegradable material, is mainly used in food packaging and pharmaceuticals. The application of polylactic acid not only promotes the development of various fields, but also meets the requirements of building a green and environmentally friendly society.

Specifications of biodegradable materials:

Biodegradable plastics Melting point ℃ Tensile strength MPa Elongation% Degradation rate Oxygen barrier Water vapor barrier Application direction
PLA 130-180 60 6 Moderate Ordinary Ordinary Hard packaging, disposable tableware, film bags, fiber fabrics, 3D printing
PBS 120 40 400 Fast Unknown Unknown Tableware, straw, modified by blending with PLA
PBAT 120 18 750 Moderate Poor Poor Soft packaging with film bags
PPC 13 650 Moderate Higher Higher Thin film class
PCL 60 20 300 Slow Ordinary Ordinary Surgery and medical field, film industry, other fields
PHA 145 30 10 Fast Higher Higher Thin film class
PGA 225 80 10 Ultrafast High High Medical field, rapid degradation products

Application and Development of PLA

PLA is actually not unfamiliar, and you may encounter it in various aspects of your life.

From the perspective of food, with the rapid development of the delivery, express delivery, and catering industries in recent years, the commercialization of PLA products has made great strides forward. In addition to paper straws, PLA straws are also commonly used when drinking milk tea in our daily lives.

From a clothing perspective, PLA clothing made by blending PLA with antibacterial agents is favored by consumers.

From the perspective of daily use, PLA, which has been plasticized and toughened, can be applied to daily necessities and children’s toys to effectively prevent children from ingesting harmful plastic particles.

From a medical perspective, by improving the hydrophilicity and biocompatibility of PLA and strengthening the control of PLA degradation time, biomedical polymers such as PLA vascular stents, absorbable materials, and surgical sutures have gradually been put into use.

In addition, materials such as PLA plastic film and sand barrier have a broad market, which is of great significance for environmental governance and has a very large application market.

The popularization of PLA can effectively reduce the use of non degradable plastics, which is of great significance for the treatment of plastic pollution.

How to choose the right toothpaste?

Summer is coming, in the face of hot weather, ice cones, ice cream, ice cream, ice drinks will also be loved by everyone. However, let go of the consequences of eating, but also give caries a chance, many people after eating cold food, there may be a toothache problem.

Toothache is a very painful thing, so it is also very important to protect dental health and oral hygiene. For example: eat less sugary, sticky and acidic foods, rinse your mouth after meals and snacks, brush your teeth and floss properly every day, etc. However, a lot of people clearly attach great importance to the protection of teeth, can still appear caries, this is why?

The problem is likely to be toothpaste, with the wrong toothpaste! Is it a choice of fluoride toothpaste or non-fluoride toothpaste? From the point of view of preventing caries, fluoride toothpaste has been fully recognized by the dental community, using fluoride toothpaste to brush teeth is recognized as a safe and effective measure to prevent caries.

Among anti-caries toothpastes, sodium fluoride and sodium monofluorophosphate are representative ingredients. In comparison with the same fluoride content, the caries prevention effect of these two components is theoretically similar, so from the point of view of caries prevention, the two choices are the same. In terms of the whitening effect. Phosphate components can be combined with calcium ions in dental stones, can effectively reduce the formation of dental stones, so as to achieve the effect of teeth whitening. Sodium monofluorophosphate is a little stronger for tooth whitening.

How to choose the right toothpaste

How to choose the right toothpaste?

Adults can choose fluoride toothpaste; People with sensitive teeth can choose anti-acid toothpaste; Children are advised to use special children’s toothpaste; Pregnant women can choose salt toothpaste; Love inverted teeth can be desensitized toothpaste; Patients with periodontal disease may consider herbal toothpaste.

Fluoride content

2 to 5 years old can use 0.05% fluoride toothpaste, 6 to 11 years old can use 0.1% fluoride toothpaste, over 12 years old can use 0.15% fluoride toothpaste.

The effect of different kinds of fluoride toothpastes on preventing caries was the same whether they contained mono – or difluoride. So we must do a good job of teeth cleaning, oral care, brushing teeth, as far as possible to avoid bacteria breeding in the mouth.

What is O-Cymen-5-OL?

It’s time for the spring and summer seasons to change again. What’s the most painful thing about each season change? “I think most people take their clothes out of the wardrobe, and there is a damp and moldy smell on them, even if they are seriously affected by moisture, there are mold spots.”. Especially when faced with clothes that you particularly like, you can’t even wash them off, and a good piece of clothing is just wasted.

Especially in areas with continuous rain, a layer of water vapor can be scraped off the walls in some places. We also have no way to deal with this natural weather. Therefore, in order to prevent clothing from becoming damp and moldy, many families use camphor pills. But when you think of camphor balls, you will remember their pungent smell, and clothes contaminated with camphor balls will also emit a strong camphor smell. If you buy some inferior products, the ingredients contained in them can also cause great harm to the human body. In order to solve such problems, I would like to share with you about the use of O-Cymen-5-OL.

What is O-Cymen-5-OL

O-cymen-5-ol also known as 4-isopropyl-3-methylphenol, or IPMP for short, is an acicular crystalline solid with a CAS number of 3228-02-2.

What is polyvinylpyrrolidone used for?

What is Polyvinylpyrrolidone?

Polyvinylpyrrolidone is abbreviated as PVP, with the molecular formula of C10H15NO and the CAS number of 9003-39-8. It is also known as Poly-1-vinyl-2-pyrrolidon, polyvinyl pyrrolidone. PVP is a non ionic polymer compound that can be divided into two forms, commonly known as powder and aqueous solution.General PVP products can be divided into three grades: industrial grade, pharmaceutical grade, cosmetic grade, and food grade. Therefore, PVP is widely used in many fields such as medicine, textiles, chemicals, beverages, and daily chemicals. So how much do you know about PVP? Let’s take you through the degradation process briefly.

Generally, we often see pvp K 15/K 30/K 60, etc. What does the K value determine? Let’s explain in detail what the K value is. The K value is an important factor determining the performance of PVP. “K value” refers to the value calculated from the viscosity measurement value of a dilute polymer solution, which is related to the degree of polymerization or molecular size. In general, the higher the K value, the greater the molecular weight, the greater the viscosity, and the stronger the adhesion. According to the specification and molecular weight of the product, it can be divided into viscosity levels of K15, K30, K60, and K90.

To facilitate your understanding, let me share with you the molecular weight corresponding to the K value of the PVP product:

PVP K value and molecular weight
Model K-value Molecular weight
PVP K12 10.2-13.8 3000-7000
PVP K15 12.75-17.25 8000-12000
PVP K17 15.3-18.36 10000-16000
PVP K25 22.5-27.0 30000-40000
PVP K30 27.0-32.4 45000-58000
PVP K60 54.0-64.8 270000-400000
PVP K90 81.0-97.2 1000000-1500000

Therefore, when purchasing products, everyone can choose the K value of PVP based on their actual needs, because different K values may have different uses for the product, and of course, the price is also different.

What does azelaic acid do for your skin?

Everyone has a love of beauty. Everyone has the right to pursue beauty, but everyone’s skin characteristics are not the same. Some people’s skin is easy to blow and break, while some people have oily skin, which is prone to acne, wrinkles, yellow spots, etc. Therefore, in order to solve skin problems, the cosmetics industry has a continuous upward trend in many industries.

In recent years, studies have shown that among many skin problems, acne skin has become the main skin problem, so consumers’ attention to acne products has been increasing. According to big data, men’s preference for acne removal is far higher than that of women. Generally, men use acne removal, oil control and facial cleaning most; In terms of age, 21-year-old teenagers have more obvious preference for acne removal. At the same time, people with oily skin have stronger preference for acne removal in terms of skin quality.

At present, more than 80% of consumers hope that acne products can achieve the effect of eliminating acne without recurrence, and 70% of consumers hope that acne products can achieve the effect of reducing acne marks. As for product prices, only 32.8% of consumers will pay more attention, and this proportion has shown a downward trend in recent years. According to the analysis of comments based on the top three categories of sales, consumers are most concerned about the functional effects of acne products, followed by the use experience and cost performance ratio.

Products with anti-acne function are basically salicylic acid, nicotinamide, arbutin, astaxanthin, lactic acid and azelaic acid. For many years, azelaic acid has been playing an important role in the field of skin care — it is most often used as a chemical exfoliator to help remove rough, dark and dead skin, without manual sanding and abrasion. If you keep an eye on the trend of skin care — you may have heard a lot about a-hydroxy acids (such as glycolic acid) and β- Information about hydroxy acids (such as salicylic acid). However, in recent years, azelaic acid is not the above two kinds of acid, but the acid that has shown great splendor.

What is azelaic acid?

Azelaic acid is a kind of skin disease prevention and treatment drug, mainly used to treat acne, chloasma and skin melanin deposition. The molecular formula of azelaic acid is C9H16O4, which is a natural dicarboxylic acid produced by Malassezia furfur. It exists in cereal, rye, barley and other products, and can also be formed by chemical synthesis, cracking and fermentation.

What is the effect of azelaic acid?

Antibacterial — directly inhibit and kill the bacteria on the skin surface and hair follicles, and eliminate pathogens.

Anti-inflammatory – inhibit the production and action of reactive oxygen free radicals, and reduce inflammation.

Anti-keratinization – reduce the synthesis of filamentous keratin and prevent excessive keratinization of hair follicles.

Whiten and lighten spots — destroy mitochondrial respiration of melanocytes, inhibit cell DNA synthesis, and thus inhibit cell proliferation.

Oil control — competitively inhibit the enzyme process that produces dihydrotestosterone, and reduce excessive skin oil induced by dihydrotestosterone.

Prevention of hair loss — it can inhibit the activity of 5a reductase, reduce the production of dihydrotestosterone (DHT), and alleviate hair loss.

Azelaic acid anti-acne texture:

Azelaic acid can solve many pathophysiological characteristics of acne, such as inflammation, proliferation of Propionibacterium acnes and hyperkeratosis of hair follicles, so it is a valuable choice for local treatment of mild to moderate acne. The anti-inflammatory effect of azelaic acid is based on inhibiting the expression of proin inflammatory cytokines. The ability to clear ROS and inhibit the production of ROS by granulocytes further support this effect. Azelaic acid inhibits the proliferation of a series of gram-positive and gram-negative microorganisms, in addition, azelaic acid affects.

Application of azelaic acid formula:

Formula category: Acne removing face cream, essence, whitening and spot removing products

Addition amount: 1% – 20%

Suggestion for use: try to keep the PH of the formula at about 4.9, which can ensure that the higher concentration of azelaic acid remains in the epidermis/dermis and the whole skin.

Acne is the most troublesome problem for teenagers. How to choose the right acne products is particularly important. Azelaic acid is a good choice. I hope this article can help you who are worried about acne.

What is hydroxypropyl methylcellulose used for?

Hydroxypropyl methyl cellulose is also called HPMC. Hydroxypropyl methyl cellulose HPMC is a non-ionic cellulose ether prepared by a series of complex chemical processes with natural polymer material refined cotton as the main raw material.

HPMC is widely used, which is widely used in chemical industry, construction, building materials, coatings, food, cosmetics, agriculture, national defense and military industry and other fields.

The following is a detailed introduction to the use of HPMC in various aspects:

1. Application of HPMC in concrete

Hydroxypropylmethylcellulose has good thickening effect and is often used as a concrete anti-dispersant. In the past, Hydroxypropylmethylcellulose is a relatively scarce fine chemical product in China, and its cost is relatively high. With the continuous development and progress of external wall thermal insulation technology in recent years, and the excellent characteristics of Hydroxypropylmethylcellulose itself, It has been widely used in the construction industry.

2.Application of HPMC in daily chemical skin care products

In the application of HPMC for daily chemical washing, HPMC is mainly used to improve the thickening, foaming, stable emulsification, dispersion, adhesion, film formation and water retention of cosmetics, and in low-viscosity products, it is mainly used for suspension dispersion and film formation.

The viscosity of the daily chemical industry mainly includes 100000, 150000 and 200000. You can choose the amount of additives in the product according to your own formula, usually about 3 to 5 ‰. Hydroxypropyl methyl cellulose is widely used in daily chemical skin care products, such as facial cleanser, lotion, shampoo, bath liquid, cream, gel, toner, hair conditioner, styling products, toothpaste, mouthwash, toy bubble water, etc.

3. Application of HPMC in putty powder

After the hydroxypropyl methyl cellulose is dissolved in the putty powder, the methoxy and hydroxypropyl groups on its molecular chain act with the aluminum ions and calcium ions in the putty powder, and then generate viscous gel, which is filled in the gaps of the putty powder, thus greatly improving the compactness of the putty powder, playing the role of reinforcement and flexible filling. However, when the composite matrix is pressed, the polymer can not play a rigid support role, thus reducing the strength and compression ratio of putty powder.

4. Application of HPMC in daily chemical washing

HPMC is a surface-treated product, which can be quickly dispersed in water and will not agglomerate. HPMC has the advantages of good thickening effect and high transparency, and is especially suitable for thickening products such as daily chemical products. The solution system has good stability, and can be non-layered, non-thinning and anti-mildew for a long time. Daily chemical grade instant HPMC is usually used in daily chemical washing products, such as hand sanitizer, laundry detergent, car wash, etc.

5. Application of HPMC in textile printing and dyeing

It is mainly used as thickener, dispersant, binder, excipient, oil-resistant coating, filler, emulsifier and stabilizer in textile printing and dyeing industry. It is also widely used in synthetic resin, leather, medicine, food, petrochemical, ceramics, paper and cosmetics industries.

6. Application of HPMC in building materials

Hydroxypropylmethylcellulose is a common building material additive, which is widely used in building materials and can be divided into many types. Hydroxypropylmethylcellulose can be divided into hot-soluble and cold-water quick-soluble types.

Hot-soluble HPMC is often used in dry powder products, directly mixed with dry powder for uniform use, such as in putty powder and mortar, while cold-water quick-soluble HPMC is often used in liquid glue, mortar, putty powder In liquid coatings and daily chemical products, HPMC can be widely used to transmit the performance of gypsum, cement and other hydrate building materials, especially in cement-based mortar, which can improve its water retention, thus extending the correction time and opening time, and reducing the problem of flow suspension.

Is hydroxypropyl methyl cellulose safe?

Health has always been a major concern. Generally, chemical raw materials are used in the construction industry. We need to carry out relevant tests for their radiation, toxic and side effects when they are used to prevent their impact on our health. The safety advantages of hydroxypropyl methyl cellulose and other raw materials are in good agreement with our use standards, so the application of such raw materials is also quite common.

HPMC is the leading product of our company, which is widely used in chemical industry, construction, building materials, coatings, food, cosmetics, agriculture, national defense and military industry and other fields.

How to quickly turn white in this winter?

Since ancient times, it has always been the unremitting pursuit of most girls to have fair and delicate skin. In ancient times, women used rice washing water to wash their faces every day in order to turn white, and even more used lead powder to cover their faces.

I believe that we have found that the dark and yellow complexion of the face often makes people feel listless and pale. Indeed, the yellow color always makes people feel less delicate and beautiful, which is why many stars pursue extreme whitening.

Yellow will affect the mental outlook of the whole person, and the heavy yellow gas will make people more haggard. Many people like to wear a white base makeup, which is also to correct the skin yellow gas. As the saying goes, “one white covers one hundred ugliness.” Although most of our Asians have warm skin tones, proper skin care and yellowing can also make our skin glow.

How is the skin dark yellow to return a responsibility? How can people with dark yellow skin turn white?

Our skin secretes melanin to protect its internal structures from UV radiation. When the skin is exposed to a large amount of ultraviolet light, the melanin production is significantly increased. The skin absorbs more ultraviolet light energy, and the skin color will be significantly darkened in other places.

Sunshine – the most easily discovered cause of skin dullness

Our skin secretes melanin to protect its internal structures from UV radiation. When the skin is exposed to a large amount of ultraviolet light, the melanin production is significantly increased. The skin absorbs more ultraviolet light energy, and the skin color will be significantly darkened in other places.

The skin is dark and yellow due to ultraviolet radiation, usually in a large range, while the facial manifestations are often spotted.

Staying up late, irregular work and rest – the most easily overlooked cause of skin dullness
Night is the golden time for our skin metabolism, especially between 11:00 and 3:00, when we don’t have a good rest, the skin metabolism is very slow, and it is also easy to cause the accumulation of melanin, making our skin look more dark and lusterless. Now many people have dark yellow skin and look listless. A large part of the reason is lack of sleep and often stay up late.

Saccharification – the most secret cause of skin dullness

The concept of skin glycosylation is a new phenomenon that has been discovered recently. Glycosylation reaction and its products will have a relatively serious impact on our body and skin.

The skin saccharification will lead to a very obvious yellow complexion and aggravate the skin aging problem. The saccharification reaction is not only affected by external factors, but also happens in our body all the time.

How to make our skin white

1. To improve this kind of skin yellow gas, prevention is more important than solution. The damage of ultraviolet rays to the skin is not only tanning and sunburn, but also the damage to the dermal structure of the skin. The luster, texture and elasticity of the skin are obviously reduced.

Therefore, the daily sun protection should not be ignored. According to the changes of the external environment, the sun protection measures should be adjusted in time to avoid excessive contact between the skin and ultraviolet rays.

2. Sleep is also very important to the skin, especially our sleep, even if you just shut your eyes for 10 minutes. Only when the human body is free of oxygen and water, can our skin shine.

3. To improve this kind of skin yellow gas, on the one hand, we need to pay more attention to daily life and eating habits, and avoid excessive sugar intake. On the other hand, for daily skin care, anti-oxidation skincare products should be used.

If the budget allows, anti saccharification skincare products should be used to prevent the occurrence of peroxidation and saccharification reaction in the skin.

These are just simple precautions. What should we do if the skin is already dark and yellow? The simplest and most effective way is to use whitening skin care products to reduce the dark and yellow skin and whiten the skin with the help of external forces.

The main ingredients of this product are nicotinamide, magnolia grandiflora extract, 3-o-ethyl ascorbic acid (transparent vitamin C) and arbutin, which can penetrate into the skin bottom layer by layer, disintegrate melanin from the root, inhibit melanin regeneration, and make the skin tender, transparent, clean and white from the inside out.

In addition, some repairing and soothing ingredients, such as squalane, crape myrtle extract, red myrrh alcohol, are also added, which can not only soothe the skin, strengthen the bottom of the muscle, but also greatly reduce the discomfort caused by the high concentration of whitening ingredients. It is very friendly for sensitive muscles!

There are also moisturizing ingredients such as sodium hyaluronate and avocado extract, which can penetrate into the skin to replenish water, and have a powerful water locking effect, making your skin more moist and plump in this dry and cold winter. It can be said that it is very suitable for this cold and dry winter. The price is also very cheap, and it is not painful to use it.

It is more suitable for skin whitening at this stage to mainly prevent melanin transmission and select products with nicotinamide, hyaluronic acid and other components as the core.

If we know the reason why the skin is dark and yellow, we just need to focus on it. In winter, there is no strong ultraviolet interference, and we are also very smooth in the whitening process.

However, the skin is dry and fragile in winter, which is also something we should pay attention to. In addition, it must not be ignored in moisturizing and stabilizing the skin. If you do a good job in these skin care tasks, whitening will become much easier.

Application of polyglyceride

What is polyglyceride?
Polyglyceride generally refers to polyglycerol fatty acid ester. Polyglyceryl ester of fat acid is the general name of a series of products, also known as PGFE. Polyglyceride fatty acid ester is a new type, high efficiency and excellent performance polyhydroxy ester non-ionic surfactant, which is used in food, daily chemical, petroleum, textile, coating, plastic, pesticide, rubber, medicine and other fields.
The appearance of polyglycerol ester can be powder, solid, mucus, etc., and the color is white to yellow. Polyglyceride has both hydrophilic and lipophilic properties, with good emulsification, dispersion, wetting, stability, foaming and other multiple properties. It has good thermal stability and good acid and salt resistance. The higher the degree of polymerization of polyglycerol in polyglycerol ester, the shorter the chain length of fatty acid, the lower the degree of esterification, and the better the hydrophilicity, on the contrary, the stronger the lipophilicity. Generally, the HLB value of polyglycerol ester is 2-20.

Application field of polyglyceride
Application of polyglyceride in food
Polyglycerides with HLB value above 7 can be used as emulsifiers. Under neutral conditions, their emulsifying capacity is significantly stronger than monoglycerides, propylene glycol esters, etc. Under acidic conditions, especially when the pH value is below 5, the emulsification and stability are obviously better than sucrose esters, and they are commonly used in the field of dairy products dominated by water. Polyglycerides with HLB less than 6 can be used as emulsifiers, either alone or in combination with other emulsifiers, and are commonly used in the fields of cream, shortening, etc.
In addition to the emulsifying capacity of other emulsifiers, polyglycerol ester also has the functions of aeration, crystallization, viscosity regulation, quality improvement, etc. It is widely used in the fields of cream, baked food, ice cream, beverages, chocolate, candy and other food fields.
Application of polyglyceride in daily chemical industry
Polyglyceride is not only safe for human body, but also has the advantages of no irritation to skin, good water dispersion resistance, good stability of lotion, etc. This kind of emulsifier is widely used in daily chemicals, especially in washing and skin care products, shampoo, hair cream and emulsified essence products.
(1) Detergent
Compared with PEG surfactants, polyglycerol ester has a slightly worse decontamination ability, but is better than sucrose ester. The detergent composed of polyglycerol ester is a safe detergent, which is harmless to human body even if it remains. For example, polyglycerol esters (polyglycerol laurate, etc.) with high HLB value are suitable for detergents such as dishes, vegetables, melons and fruits, and are safer than general synthetic detergents.
(2) Cosmetics
Polyglyceride can be used in various cosmetics as emulsifier, solubilizer, stabilizer, humectant, etc., which can significantly improve product quality. Polyglyceride is less irritating to skin and hair, and has high safety. It can be used in advanced cosmetics and children’s skin care products.

The triglyceride diisostearate can be used in ordinary lotion, as well as eye shadow and lipstick products. In addition, as a co emulsifier, triglyceride monolaurate has a good effect in hand cream. Polyglycerides with high HLB value such as polyglycerol laurate can be used as solubilizers to solubilize essence and fragrances in aqueous systems. Polyglycerides with low HLB esters, such as polyglycerol decanooleate, are suitable as solvents for making anhydrous cosmetics.
Application of polyglyceride in pharmaceutical industry
Polyglyceride can be used as emulsifier, solubilizer, dispersant and penetrant in medicine due to its good safety, acid resistance, hydrolysis resistance and drug compatibility. For example, some polyglycerol stearate can regulate the dissolution of some drugs, which can effectively control the release of drugs.
Application of polyglyceride in rubber and plastics
Polyglyceride has excellent heat resistance. It can be used as internal lubricant, plasticizer, emulsifier, antistatic agent and anti fogging agent in polyethylene, polypropylene and other resins. In addition, polyglycerol ester can also be used as an improver of natural rubber and synthetic rubber.
Application of polyglyceride in textile industry
In the textile printing and dyeing industry, polyglycerol ester can be used as a fiber softener, antistatic agent, fabric evener, etc. to improve the wettability and softness of textile products, effectively reduce friction, and prevent the accumulation of static electricity.
Applications in other fields
In addition to the above fields, polyglycerol ester can also be used in the pesticide field as an emulsifier to improve the dispersion of drugs.
In addition, we also provide relevant glyceride products, the list is as follows:

The Ultimate Guide for Beginners of Skin Care

When creating your first skin care program, please keep it simple, put a simple daily life together – and stick to it.

The most important skin care advice is to keep it simple, start with your basic knowledge, and then expand as needed. The basic knowledge should always include the following three steps in the following order:

Step 1: Cleaning

The general rule of thumb here is: clean your skin twice a day, once in the morning and once in the evening. Cleaning in the morning will help remove sweat or grease left on the pillow and hair during beauty sleep.

There is a common exception to the rule of twice a day: dry skin. If your skin tends to be dry, use plain boiled water in the morning.

However, cleaning your skin at night should not be compromised or skipped. At the end of the day, it is important to clean, not only to remove the skin care products and cosmetics applied in the morning, but also to remove the excess oil, sweat, dead skin cells, pollutants and other debris accumulated on the skin all day long.

When choosing facial cleansers, beginners should choose mild and moisturizing facial cleansers. Any skin type can tolerate moisturizing facial cleansers. In addition, look for a fragrance free product with the least ingredients (to avoid irritation) and containing ceramide and glycerin to restore and maintain the skin barrier.

Step 2: Moisturizing

Next, use a moisturizer or moisturizing product. We generally recommend oil-free, fragrance free moisturizers because they are well tolerated in all skin types, from acne prone to sensitive.

In addition to these parameters, you can also look for a moisturizer containing other ingredients for specific needs, while solving specific skin problems. The general list of skin care ingredients is a very long and changing list, so for the purpose of this article, the following are some top ingredients related to moisturizers:

Hyaluronic acid: make skin plump and restore lost moisture.

Ceramide: critical to skin barrier strength and overall health (important for patients with dry skin and eczema).

Vitamin C: Provides antioxidant protection and overall skin whitening.

If you have oily or acne prone skin, don’t think you can (or should) bypass the use of daily moisturizers. Excessive washing without proper use of moisturizing cream can actually lead to excessive production of oil on the skin.

No matter how greasy your skin feels or is prone to acne, it will become dry without moisturizing. Dry skin is irritated skin. Those with oily skin should look for non acne moisturizers.

Step 3: Protection

Sunscreen is your first line of defense and protective measure against skin cancer. If you don’t do anything else to your skin, sunscreen is the most important.

Select SPF 30 or higher sunscreen and apply it every day (even if it is cloudy), always as the last step in the skin care program.

There are two ways to choose which type of sunscreen to use: chemical or mineral based. Mineral sunscreen acts as a shield, blocking the sun’s rays from penetrating the skin, thanks to ingredients such as zinc oxide or titanium dioxide.

Once you have a basic routine, you can start adding additional steps here and there as needed.

A good starting point is to exfoliate, add additional steps once or twice a week, and use α- Hydroxy acid (AHA) or β- Hydroxy acids (BHA), which remove excess accumulations on the skin surface in different ways.

You can also choose two different exfoliation methods: physical and chemical. Chemical exfoliators are very suitable for inducing cell renewal, increasing collagen formation and improving darkness. Physical exfoliation is to manually remove dead skin cells, excess oil and accumulations through facial scrub.

Sensitive skin types may want to avoid physical exfoliators because they can irritate the skin and cause blood vessel rupture.

You can rotate other daily additional steps including essence and facial mask as needed. Facial essence is an efficient and lightweight skin care product for external use, which is formulated with higher concentrations of active ingredients (such as vitamin C and hyaluronic acid) to address more specific skin problems.

Remember these important tips:

Less is more

Reducing your skin care plan and sticking to the key and important active ingredients will serve you better than doing too many things. Insist on using products with few ingredients and no spices, and try new products one by one, so that you can see the skin reaction.

Patient

If a new skin care program does not seem to work immediately, you should know that patience is necessary when it comes to skin care (please note if any product promises immediate results). Don’t do too many experiments. Before the conversion, give your skin a chance to get used to the product or active agent for at least two to three months.

 

Of course, the exception here is that if skin care products cause any type of irritation or allergic reaction, in this case, please stop using them immediately.

Consistency is key

Be consistent, it has to do with the patience part. Like many things in life, keeping consistent and going through the same skin care procedures every morning and evening is the key to producing and maintaining practical effects. Bottom line: Believe in the process (and your own skin) and stick to any plans you make for yourself.
