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.

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%.

What is Sodium Monofluorophosphate？

Sodium Monofluorophosphate is referred to as “SMFP” is a chemical substance, CAS 10163-15-2 white powder or white crystal, easily soluble in water, strong hygroscopic, at 25 degrees water dissolution is no side effects and no corrosion. Sodium monofluorophosphate contained in toothpaste is an excellent anti-caries agent and tooth desensitization agent. The conventional content of Sodium Monofluorophosphate in toothpaste is 0.7-0.8%, and the conventional content of fluorine in drinking water is 1.0mg/L. Sodium monofluorophosphate in aqueous solution has obvious bactericidal effect, and has obvious inhibitory effect on melanomycin, staphylococcus aureus, salmonella and so on. Sodium monofluorophosphate is widely used in toothpaste additives, concrete corrosion inhibitors, food, medical and other aspects.

Is sodium monofluorophosphate good for your teeth?

Sodium Monofluorophosphate is an inorganic compound used in toothpaste to prevent tooth decay and improve tooth sensitivity. The specific analysis is as follows:

Sodium Monofluorophosphate is widely used in fluoride toothpastes, which can promote tooth remineralization and prevent tooth decay. It has a good effect on people with sensitive teeth and will not irritate teeth after use. However, sodium monofluorophosphate has a certain toxicity, the content of sodium monofluorophosphate in toothpaste is 0.7%-0.8%, and generally a small amount of ingestion will not have any effect. If swallowed for a long time, it may lead to fluorosis, and may also cause tooth deformity, softening, loss of luster, etc., resulting in dental hypoplasia.

What are the risks of sodium monofluorophosphate?

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.

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.

Hydrogenated rosin is one of the rosin modified products. The conjugated double bonds of abietic resin acids in rosin are partially or completely saturated with hydrogen gas under a catalyst, certain temperature, and pressure.

Hydrogenated rosin is an important rosin modified product with good oxygen resistance, low brittleness, high thermal stability, and light color. Hydrogenated rosin is widely used in industries such as adhesives, synthetic rubber, coatings, inks, papermaking, electronics, and food. Mainly used in rubber, food, medicine, electronics, paper making, building materials, etc.

Unilong offers various grades of hydrogenated rosin, including premium and first grade. Level 2, can be selected according to your needs.

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, 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.

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. Unilong is the leader in the sodium monofluorophosphate industry and one of the professional manufacturers of sodium monofluorophosphate for toothpaste industry. With high-quality products, Unilong has established long-term cooperation with many daily chemical companies such as Colgate, Unilever, LG, etc. In terms of overseas markets, our sodium monofluorophosphate product has been exported to Thailand, Malaysia, Lebanon, India and other regions, and we has the strength to compete with international companies in the same field.

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.

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.

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?

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.

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.

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.

2. Make the skin soft

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

3. 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.

4. Delaying skin aging

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

5. 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.

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?
