In the pursuit of beauty and skin health, we often see some familiar and unfamiliar names in the ingredients list of skin care products: hyaluronic acid, sodium hyaluronate, hydrolyzed sodium hyaluronate. They frequently appear in a variety of serums, creams, masks, known as the skin moisturizing, anti-aging secret weapon. But what is the difference between the three? Is it a marketing gimmick, or is it really different? Today, let’s uncover their mystery and explore the unique features of these three ingredients.

Hyaluronic acid: the elder statesman of moisturizing

Hyaluronic acid, also known as hyaluronic acid, is a linear macromolecular acid mucopolysaccharide that occurs naturally in human and animal tissues. Its chemical structure is unique. D-glucuronic acid and n-acetylglucosamine are interlinked to form disaccharide units through specific glucoside bonds. Numerous disaccharide units are interlinked to form the molecular chain of hyaluronic acid, making it show a unique column-shaped spiral structure in space. It is this special structure that gives hyaluronic acid its powerful moisturizing ability. Its molecules can carry hundreds of times their own weight of water, which can absorb and lock in a large amount of water, forming a layer of hydrating protective film on the surface of the skin, preventing water loss and keeping the skin hydrated and full at all times.

In the world of skin care, hyaluronic acid is a star ingredient. Whether it is an affordable moisturizing lotion, or a high-end essence cream, you can often see it.

Sodium hyaluronate: The Transformation of hyaluronic acid

Sodium hyaluronate is actually a salt derivative of hyaluronic acid formed by combining with sodium ions. In terms of chemical structure, it introduces sodium ions on the basis of hyaluronic acid, and this small change makes a huge difference. The existence of sodium ion enhances the stability of hyaluronic acid, so that it can maintain a relatively stable state in various environments and is not easy to decompose. At the same time, the solubility of sodium hyaluronate has also been greatly improved, and it can quickly dissolve in water, which makes it easier to be added and mixed in the production process of skin care products and cosmetics, greatly broadening its application range.

In practical application, the advantage of sodium hyaluronate is very obvious. In the field of skin care products, its moisturizing ability is also excellent, can penetrate into the bottom of the skin, firmly lock in moisture, so that the skin always keep hydrated. Moreover, due to its good stability and solubility, sodium hyaluronate can be added to a variety of dosage forms of products, such as lotions, creams, serums, masks, and even some makeup products, it can be found. Sodium hyaluronate moisturizing cream, light and delicate texture, applied on the skin quickly absorbed, skin immediately feel hydrated and nourished. Long-term use can not only improve the dryness of the skin, but also enhance the barrier function of the skin and reduce the damage of the external environment to the skin. In addition to skin care products, sodium hyaluronate has a wide range of applications in the medical field, such as eye surgery, it is often used as eye moisturizer to maintain the moist environment of the surgical site; In joint treatment, it can be used for joint fluid replacement to relieve the pain of arthritis patients.

Hydrolysis of sodium hyaluronate: High energy of small molecules

Hydrolyzed sodium hyaluronate is a product obtained by hydrolysis of high molecular weight sodium hyaluronate. In the hydrolysis process, the large molecular chain of sodium hyaluronate is cut off and decomposed into smaller molecular weight fragments to form hydrolyzed sodium hyaluronate. This small molecule property gives it a unique advantage, making it play an important role in skin care products.

Due to the smaller molecules, hydrolyzed sodium hyaluronate has better permeability, can easily penetrate the cuticle of the skin, deep into the bottom of the skin, and directly transport water to the dermis of the skin to achieve deep moisturizing in the true sense. Moreover, it also has a good transdermal absorption and promotion effect, which can help the skin better absorb other nutrients and improve the efficacy of skin care products. In addition to moisturizing, hydrolyzed sodium hyaluronate also has certain anti-inflammatory, repairing and antioxidant properties. It can inhibit the production of inflammatory factors, reduce the skin inflammatory response, for sensitive skin and acne skin has a good soothing and repairing effect; At the same time, it can also remove free radicals, reduce oxidative damage, and delay skin aging.

In many skin care products, the figure of hydrolyzed sodium hyaluronate is also common. With the addition of hydrolyzed sodium hyaluronate moisturizing serum, the skin can feel refreshed and hydrated quickly after use, and with the increase of use time, the dry and rough skin problem has been significantly improved, becoming more delicate and smooth.

To visualize the differences between hyaluronic acid, sodium hyaluronate, and hydrolyzed sodium hyaluronate, we use the following table to summarize the comparison:

Although hyaluronic acid, sodium hyaluronate and hydrolyzed sodium hyaluronate are closely related to moisturizing and skin beauty, they have obvious differences in chemical structure, molecular weight, moisturizing ability, permeability and efficacy, and each plays a unique role in skin care products and other fields. In the pursuit of beauty on the road, we should look at these ingredients rationally, according to their skin type and needs, scientifically choose their own skin care products. At the same time, we should also pay attention to the quality and safety of the product, and avoid being misled by some exaggerated propaganda. I hope everyone can find their own beauty code through scientific skin care, and make the skin glow healthy and charming.

What is potassium myristate CAS 13429-27-1？

Potassium myristate, alias potassiumtetradecanoate, CAS number is 13429-27-1, molecular formula is C14H29KO2, molecular weight reached 268.48. From the point of view of chemical structure, it is an organic salt produced by the reaction of myristic acid and potassium hydroxide. Myristic acid is a saturated fatty acid commonly found in vegetable oils such as coconut oil and palm oil, as well as some animal fats. When myristic acid and potassium hydroxide meet in an acid-base neutralization reaction, the carboxyl group (-COOH) in myristic acid combines with the hydroxide group (OH) in potassium hydroxide to form water, while potassium ion (K +) combines with the myristic ion (C14H27COO⁻) to form potassium myristic acid.

Potassium myristate CAS 13429-27-1 at room temperature and pressure is usually presented as a white to light yellow powder substance, delicate texture, giving a relatively dry intuitive feeling. It has certain solubility characteristics, can show good solubility in water, and can be evenly dispersed in water to form a solution, which makes it play a good role in some water-based system products. However, when it encounters organic solvents, such as common ethanol, ether, etc., the solubility will be greatly reduced and almost insoluble. This is because the molecular structure of potassium myristate determines that it is more inclined to interact with water molecules, and the interaction between organic solvent molecules is weak.

From the point of view of chemical properties, potassium myristate is a strong base and weak acid salt. When it is dissolved in water, a hydrolysis reaction occurs. The myristate ion (C14H27COO⁻) binds to hydrogen ions emitted by hydro electricity (H +). This causes a relative increase in the concentration of the hydroxide ion (OH⁻) in solution which causes the alkaline appearance of the solution. Under general storage conditions, potassium myristate has good stability and can keep its chemical structure and properties unchanged for a long time. However, if it is exposed to high temperature, high humidity or strong acid and alkali environment, its stability will be challenged. The decomposition reaction of potassium myristate may occur in high temperature environment, resulting in the decrease of its active component content. Under strong acid-base conditions, it will chemically react with acid or base to form other substances, thus losing its original properties.

Potassium myristate plays an important role in cleaning

On the big stage of cleaning products, potassium myristate CAS 13429-27-1 plays a key cleaning role. Its cleaning principle is based on its unique chemical structure and surface active properties. The potassium myristate molecule consists of a hydrophilic head (the carboxylate part) and a hydrophobic tail (the long-chain fatty acid part), a special structure that allows it to form micelles in water. When potassium myristicate comes into contact with dirt and oil on the skin surface, its hydrophobic tail is inserted into the oil molecules, while the hydrophilic head is oriented towards the water phase. In this way, potassium myristate can wrap the oil, forming tiny micelles, which can be evenly dispersed in the water and washed away with the water flow, so as to achieve a clean effect.

Potassium myristate is widely used in facial cleansers. Potassium myristate works in concert with other soap-based ingredients to penetrate deep into pores and strongly cleanse the skin of oil, dirt and aged keratin. For people with oily skin, use a facial cleanser containing potassium myristate, which can effectively remove excessive oil from the face and keep the skin fresh and clean. However, due to its strong cleaning power, it may be irritating for people with dry and sensitive skin, and the frequency of use should not be too high.

In body wash products, potassium myristate can quickly combine with dirt, sweat and oil on the surface of the body, by producing a rich foam, these dirty things away from the skin, so that we can feel fresh and clean skin after bathing. At the same time, the shower gel also adds some spice ingredients, while cleaning, to bring users a pleasant fragrance experience.

While potassium myristate is excellent at cleansing, it is not “friendly” to all skin types. For dry skin, due to less skin oil secretion, the moisturizing ability of the skin is relatively weak, and the water content of the stratum corneum is low. While the strong cleaning power of potassium mystate removes the dirt and oil on the skin surface, it will excessively clean the oil secreted by the skin itself, causing the skin’s moisturizing barrier to be damaged to a certain extent, resulting in more dry skin and water shortage, tightness, peeling and other uncomfortable symptoms. For example, some people with dry skin who use a facial cleanser containing potassium myristate can feel as if their face is wrapped in a tight film, and in severe cases, there will be fine dandruff.

The epidermal layer of sensitive skin is thin, the barrier function of the skin is fragile, and the resistance to external stimulation is poor. The alkaline properties of potassium myristate may upset the original acid-base balance on the skin surface, stimulate nerve endings in the skin, and trigger allergic reactions in the skin. For people with sensitive skin, after using cleaning products containing potassium myristate, the skin may quickly appear redness, itching, tingling and other symptoms, seriously affecting the health and comfort of the skin.

If after the use of products containing potassium myristate, the skin appears redness, itching, stinging and other uncomfortable symptoms, this is likely to be the skin has an adverse reaction to the product, at this time should immediately stop using. At the same time, do not scratch the skin with your hands at will, so as not to increase the risk of skin damage and infection. You can gently rinse the skin with water to remove the residual product components on the skin, and then observe the skin condition. If the symptoms continue to not relieve or worsen, be sure to go to the hospital dermatology treatment in time, let a professional doctor for diagnosis and treatment.

When choosing products containing potassium myristate, be sure to maintain a rational and scientific attitude. Know your skin and make decisions based on your needs. If you have oily skin, moderate use of cleansing products containing potassium myristate can help you effectively cleanse your skin and keep it fresh. But if you have dry or sensitive skin, you need to choose carefully or look for other, gentler cleansing ingredients instead. At the same time, in the process of use, strictly follow the use recommendations and precautions to avoid damage to the skin due to improper use. I hope everyone can keep the skin healthy and beautiful through scientific choice and correct use.

Cocoyl chloride CAS 68187-89-3, From the appearance, coconut chloride is a colorless or light yellow transparent oily liquid. This visual feature makes it recognizable among many chemical raw materials. It has a strong pungent smell, which is not only very pungent, but also highly volatile. Once it spreads in the air, it will quickly irritate people’s respiratory tract and eyes, causing discomfort.

In terms of density, the density of coconut chloride is about 0.91g/mL (25°C), which means that it is different from the density of water. In scenarios involving mixing with water, stratification and other phenomena will occur due to the density difference. Its boiling point is 193°C (4mmHg). The relatively high boiling point indicates that it can maintain a relatively stable liquid state at room temperature and pressure. The flash point is greater than 230°F, which reflects that coconut oil chloride is relatively difficult to ignite when encountering fire sources such as open flames and high temperatures, and has a certain degree of fire safety. However, it can be dissolved in organic solvents such as ether, and this solubility makes it possible for it to be mixed with other organic compounds in the chemical synthesis process.

PVP polyvinylpyrrolidone with CAS 9003-39-8, is a linear polymer polymerized from N-vinylpyrrolidone (‌NVP)‌. ‌Its molecular formula is (C6H9NO)n, ‌where n represents the degree of polymerization, ‌that is, the molecular weight of the polymer. ‌PVP has specific chemical structure and physical properties, ‌making it widely used in many fields.

With the increasing severity of global environmental problems, reducing plastic pollution and promoting sustainable development have become urgent issues to be solved. Biodegradable plastics are of great significance to environmental protection because of their ability to degrade in the natural environment and reduce long-term plastic waste. Such materials can be broken down by microorganisms under certain conditions and eventually converted into carbon dioxide, water and biomass, reducing the damage to the ecosystem. However, biodegradable plastics still need to be further optimized in terms of mechanical properties and degradation rate.

‌ The application of polivinilpirrolidone  in biodegradable plastics is mainly reflected in its application as a modifier, which significantly improves the mechanical properties and degradation rate of the material by combining with other biodegradable materials. ‌

PVP is a synthetic water-soluble polymer with high solubility, adhesion and chemical stability. Due to its good film formation and chemical stability, PVP can be used as a modifier to combine with other biodegradable materials such as polyvinyl alcohol (PVA) to significantly improve the overall environmental performance of the material. For example, studies have shown that PVP can increase the hydrolysis rate of PVA, thus accelerating the biodegradation process of plastics‌. In addition, the introduction of PVP can also increase the toughness and elasticity of the material, making it more durable and reliable in practical applications‌.

PVP is used as a catalyst to accelerate the degradation of plastics. Compared with traditional plastic degradation technology, PVP catalytic degradation technology has the following advantages:

(1) Low cost: PVP, as a common and cheap polymer, has a relatively low cost of degradation reaction, which is convenient for large-scale application;
(2) Efficient degradation: PVP catalyst can effectively decompose plastics, accelerate the degradation process, so that the degradation rate can be improved, and the degradation effect is more significant;
(3) Environmental protection and sustainable: PVP catalytic degradation technology can achieve efficient degradation of plastics, and will not produce toxic and harmful substances, more friendly to the environment.

The combination of PVP and PVA is a typical successful case. PVA/PVP hydrogels prepared by γ-ray irradiation have demonstrated excellent biodegradability and antimicrobial properties, which makes them have wide application potential in medical and agricultural fields. Specific case studies have shown that the degradation rate of PVA/PVP hydrogels in soil is significantly increased, helping to reduce the environmental impact of agricultural waste‌.

The advantages of PVP as a modifier lie in its high solubility, excellent film formation and chemical stability, which enable it to enhance the mechanical properties and degradation rate of biodegradable plastics. However, PVP is not a fully biodegradable material on its own, so it needs to be combined with other biodegradable materials when used. In addition, PVP is heavily used in aquaculture as a polymer that is difficult to biodegrade and may cause long-term pollution to the environment.

In summary, the application of PVP in biodegradable plastics is mainly through combining with other biodegradable materials to significantly improve the performance and environmental adaptability of materials.‌

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.

Il 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.

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？

Sodio monofluorofosfato 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.

Sodio monofluorofosfato 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.

Applicazione

1. Application in the separation of copper and lead Tioglicolato di sodio, 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.

What is Sodium Monofluorophosphate？

Sodio Monofluorofosfato 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.

Methylcyclopentadienyl manganese tricarbonyl, abbreviated as MMT, has been widely used in the world’s oil refining enterprises mainly as a good antiknock agent for gasoline since its advent.

In passato, grazie all'indietro conoscenza medica e di condizioni limitate, la gente era poca consapevolezza di protezione del dente, e molte persone non capiscono perché i denti devono essere protetti. I denti sono i più difficili organo del corpo umano. Sono abituato a mordere, mordere e macinare il cibo, e aiutare con la pronuncia. Umana denti anteriori hanno l'effetto di strappare il cibo, e la parte posteriore dei denti hanno l'effetto di macinare il cibo, e il cibo favorisce la digestione e l'assorbimento di stomaco dopo essere stato completamente masticato. Pertanto, se i denti non sono buone, è molto probabile che interessano i nostri problemi gastrointestinali.

Inoltre, i denti non sono buone, ma anche causare dolore, come dice il proverbio: “mal di denti non è una malattia, fa davvero male”, perché i nostri denti sono ricoperti di radici dello stesso nervo, il dolore attraverso queste dense piccolo nervo trasmissione. Un altro punto che non può essere ignorato, bad denti porterà anche l'alito cattivo, la gente seria influenzano la comunicazione interpersonale, quindi è molto importante per proteggere i denti!

Come posso mantenere i miei denti e gengive sani?

Non è difficile tenere la bocca pulita, sana e coerente. A seguito di una semplice routine quotidiana può aiutare a prevenire la maggior parte dei problemi dentali: utilizzare un dentifricio al fluoro, lavarsi i denti ultima cosa di notte e almeno una volta durante il giorno; Mantenere una buona dieta, ridurre il numero di alimenti zuccherati e bevande che mangiamo, e visitare il vostro dentista regolarmente.

Anche se la maggior parte delle persone lavarsi i denti regolarmente, alcune persone non andare dal dentista per controlli regolari. Alcuni piccoli cambiamenti nelle vostre abitudini quotidiane possono fare una grande differenza nel tempo. Un dentista può rimuovere i depositi di tartaro e il tartaro dai denti e trattamento esistente malattia di gomma. Tuttavia, quotidiana di cura dentale è fino a voi, e le armi principali sono il vostro spazzolino da denti e dentifricio.

Come scegliere il dentifricio? Tra anti-carie dentifrici, fluoruro di sodio e sodio monofluorofosfato sono rappresentante ingredienti. Ci sono anche fluoruro stannoso e così via, che sono utilizzati in un dentifricio al fluoro. Come lungo come il fluoro contenuto nell'anti-carie dentifricio raggiunge 1/1000, può efficacemente prevenire la carie. In caso di stesso il contenuto di fluoro, l'anti-carie effetto dei due componenti, in teoria, è simile, dal punto di vista della prevenzione della carie scegliere, le due scelte sono le stesse. A giudicare dall'effetto sbiancante. Fosfato componenti possono essere combinati con gli ioni calcio nei denti pietre, che può efficacemente ridurre la formazione di dentale pietre, in modo da raggiungere l'effetto di sbiancamento dei denti. Sodio monofluorofosfato è un po ' più forte a sbiancare i denti.

Attualmente, in alcuni supermercati, la maggior parte delle varietà di dentifricio sono etichettati come dentifricio al fluoro o di sodio monofluorofosfato di principio attivo. Così, è il sodio monofluorofosfato di buono per i vostri denti?

Sodio monofluorofosfato (SMFP) è una sostanza chimica, bianco o polvere di cristallo bianca, facilmente solubile in acqua, forte igroscopicità, al 25° l'acqua di scioglimento è privo di effetti collaterali e di corrosione. Sodio monofluorofosfato di dentifricio industria è usato come un anti-carie, l'agente di desensibilizzazione additivo, e utilizzato anche come conservante, battericida e dentifricio trattamento. Convenzionale contenuto nel dentifricio è di 0,7-0,8% e il convenzionale, il fluoro contenuto nell'acqua potabile è di 1.0 mg/L. La soluzione acquosa di sodio monofluorofosfato, come è ovvio, l'effetto battericida. È evidente effetto inibitorio sulla melanosomin, staphylococcus aureus, salmonella e così via.

Fluoro può essere applicato in una varietà di modi in odontoiatria. Oltre ai gas fluorurati prodotti per l'igiene orale quotidiana, come dentifricio e colluttorio, ci sono speciali trattamenti dentali disponibili in forma di gel e vernici, tra gli altri, presso l'ufficio del dentista. Il modo più comune è quello di applicare fluoro per via topica da lavarsi i denti ogni giorno con un dentifricio al fluoro, che protegge lo smalto da batteri in bocca. È importante utilizzare un dentifricio al fluoro nella vostra spazzolatura quotidiana fin dall'infanzia. In questo modo, i denti godere di una migliore salute e la protezione per tutta la loro vita, riducendo il rischio di carie e altre patologie del cavo orale.、

Negli anni, il mondo ha studiato l'anti-carie effetto di sodio monofluorofosfato utilizzato nei dentifrici e la sua tossicità per l'organismo umano, anche se dopo aver ripetuto di ricerca e di molti dibattiti, la conclusione finale è che il sodio monofluorofosfato è sicuro per il corpo umano in anti-carie aspetto e può essere utilizzato con la pace della mente.

Ioduro di potassioun additivo alimentare, è un composto ionico in cui ioni di iodio può formarsi un precipitato di colore giallo scuro di ioduro d'argento con ioni d'argento (vedi foto di decomposizione, che può essere utilizzato per fare l'alta velocità, pellicole fotografiche). Pertanto, il nitrato di argento può essere utilizzato per verificare la presenza di iodio ioni. Iodio, come componente della tiroxina, è strettamente correlato al metabolismo di base del bestiame e del pollame, partecipando a quasi tutto il materiale processi del metabolismo. La carenza di iodio in allevamento può causare iperplasia della tiroide e ipertrofia, diminuire il tasso metabolico di base, e di influenzare la crescita e lo sviluppo. Lo iodio è necessario aggiungere il feed della giovane bestiame e bestiame in aree a deficit di iodio. Ad alto rendimento vacche da latte e galline ovaiole richiedere anche un aumento di iodio, iodio e deve essere aggiunto alla loro alimentazione.

Che cosa è l'applicazione di ioduro di potassio

Anti radiazioni effetti: Vari paesi potranno distribuire o riserva compresse di iodio per i residenti intorno alle centrali nucleari, la cui componente principale è di ioduro di potassio. In caso di fuoriuscita di radiazioni dalle centrali nucleari a causa di disastri, permettendo dintorni residenti a prendere compresse di iodio può saturare lo iodio nella tiroide e ridurre l'assorbimento di sostanze radioattive Chemicalbook iodio 131 dalla tiroide. Tuttavia, è necessario prendere entro le 4 ore, quando esposti ad iodio libero di radiazione per avere un effetto, e non può impedire la connessione di radiazione e di altri isotopi di iodio-131. L'uso improprio da parte di persone comuni, senza istruzioni, può causare sintomi di ipertiroidismo.

Ioduro di potassio è una materia prima per la produzione di ioduri e coloranti. Utilizzato come fotosensibile emulsionante per la fotografia. In medicina, è usato come espettorante, diuretico, gozzo la prevenzione e il trattamento dell'agente, così come pre-operatoria farmaco per l'ipertiroidismo. Esso è utilizzato anche nella produzione di reumatiche antidolorifici con analgesici e sangue effetti di attivazione. Si tratta di una co solvente di iodio e di certo insolubile ioduri metallici.
