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.

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.

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.

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.

的 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.

应用

1. Application in the separation of copper and lead 巯基乙酸钠, 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.

氟磷酸钠 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. MMT, decomposed into active manganese oxide particles under combustion conditions, due to its surface effect,(destroy the peroxides already generated in the automobile engine, resulting in a reduction in the concentration of peroxides in the pre-flame reaction, while selectively interrupting a part of the chain reaction, thereby preventing automatic ignition, reducing the speed of energy release, so that the antiknock of the fuel is improved.

在这一点上，我们首先想到的是冰箱存储。 然而，有许多种类的食品和饮料存储在冰箱，其中有许多食物，"注入的细菌"到冰箱，例如鸡蛋可能带有沙门氏菌和原肉、水果和蔬菜，可进行致病性大肠埃希氏菌、病原的金黄色葡萄球菌和寄生虫。 和冰箱里还有一个保存期保存。 一般来说，食物，需要2-3天必须要吃掉，否则会腐烂在冰箱里随时间。 同时，冰箱里还有一定量的存储空间，这是只有用于家庭使用。 如果这是一个大型超市，我们如何保持新鲜的食物从源的商人，我们购买的?

与经济全球化的发展，进口和出口水果和蔬菜，已经成为常态。 面对这种情况下，我们要研究一种新型的防腐剂-1-MCP水果和蔬菜的防腐剂。 一旦产品的开发，它收到了一个高反应。 因为这是一个无毒的，非常安全的，明显有效的防腐剂。 接下来，让我们来谈谈成分1-MCP水果和蔬菜的防腐剂。

什么是1-甲基环丙烯?

1-甲基环丙烯缩写为1-MCP在英国， CAS3100-04-7 化学式是C4H6. 在正常的温度和压力，外观是无色的天然气、无毒无味，与密度的0.838g/cm3。 它是一个非常活跃的环丙烯的化合物。 1-甲基环丙烯的主要用作一种植物生长调节剂，被广泛使用在该领域植物保存。 它具有优势的低消耗、良好的保效果和高安全性。

特征的1-MCP

1-MCP 可以抑制释放的乙烯的工厂本身，并且也块结合的乙烯相关受植物细胞，从而抑制的成熟作用的乙烯。 因此，应用的1-Methylcyclopene可以有效地延长的成熟和老化过程的植物，从而延长他们的货架寿命，减少了腐败和废物在运输和储存，以及延长寿命物品。

应用的1-MCP

1-MCP 可以适用于保存水果、蔬菜和鲜花，以防止植物凋萎. 例如，当应用于水果和蔬菜，如苹果、梨、李子、猕猴桃、和西红柿，它可以延迟他们的成熟，减少水的蒸发和维护他们的硬度、口味和营养组成；在条款花的保护，它可以维持的颜色和香气的花朵。 此外，1-Methylcyclopene还可以提高植物疾病的抵抗。 1-Methylcyclopene是一个新的里程碑，在水果和蔬菜保存经修改的气氛中保存。

之后的流行病，经济恢复和发展的全球贸易逐渐扩大。 每年，每个国家都会产生大量的新鲜水果和蔬菜。 由于发育不完善的农产品冷链的物流，大约85％的水果和蔬菜用普通的物流、导致大量的衰减损失，其中还提供了一个广阔的市场空间为促进和应用的1-甲基环丙烯. 因此，可以看出， 1-MCP 有广阔的发展前景的，不仅对各种呼吸更年期的水果和蔬菜，但是还可以有效地延长收获后的储存和货架寿命，特别是用于乙烯敏感的水果和蔬菜，和可以保持原有品质水果和蔬菜很长一段时间。

5. 改善黄褐斑

与增长时代，许多妇女有黄褐斑在他们的面孔。 的护肤产品中含有的鲨可以使用的，因为鲨鱼的模式已降低的效果黄褐斑。

有什么特点的鲨?

鲨是一种稳定的、皮肤友好，柔和，温和的和活跃的高端自然油。 它的外观是无色的透明的液体具有很高的化学稳定性。 鲨丰富的纹理和不油腻后分散的应用程序。 鲨是一种类的石油与优秀的意义上使用。 由于其良好的渗透性和清洁的影响皮肤的，它被广泛用在化妆品行业。

鲨 是一个自然组成部分的皮脂，这可以被认为是仿皮和可以帮助其他活性成分的渗透;鲨发挥至关重要的作用，在皮肤屏障修复。

鲨是非常温和，因为它的稳定性和纯度高，少杂质的产品，并且它是一部分皮肤。 它可以适用于敏感的皮肤和皮肤的宝宝而不会导致粉刺。 它没有粘性的感觉期间和之后应用程序，并有一个柔软的垫子在吸收后，提高柔软的感觉和滋润的皮肤。

鲨 为饱和的烷烃。 在高温下和紫外线辐射，它将不会被腐臭的像植物油。 它是稳定在-30℃-200℃并且可以使用在热塑性塑料制品（如口红。 鲨可以使用护发产品来提高亮度和疏远；没有对皮肤刺激性，不过敏的,十分安全，特别是适用于婴儿护理的产品。

虽然只有一个字的差别角鲨和鲨烯、鲨更具有优势，具有很好的皮肤的亲和性、渗透率和滋润的效果。 但是不要盲目神化的效力的角鲨烷。 购买时的护肤产品中含有的鲨，你应该考虑成本效率。 鲨不建议购买的产品价格膨胀。

随着夏季的到来，更多的人注意到他们的皮肤，尤其是女性朋友。 由于大量出汗的和强大的石油分泌在夏天，结合强的紫外线的太阳，这是很容易的皮肤晒伤，加速皮肤老化和色素沉积，以及在严重的情况下，即使开发的斑点。 因此，夏天的护肤是特别重要的。 本文首先从三个方面：太阳保护、清洁和保湿和引入了我们应该如何照顾我们的皮肤在夏天？

防晒霜

防晒霜是一个重要步骤，在夏季。 一般来说，它被广泛认为，防晒霜是防晒伤。 事实上，预防晒伤仅仅是一种表面现象，它是帮助我们防止皮老化、色素沉着、皮肤病等。 因此，使用防晒霜的护肤产品在夏季，是必不可少的。 当选择的防晒用品,这是最好的选择防晒霜用防晒指数值大于30。 在使用过程中，应注意到完整性和统一性的应用以实现更好的结果。

清洁

在夏天，每个人都知道汗和石油分泌力和身体很容易出汗以及痤疮。 因此，清洗步骤在夏天也是至关重要的，尤其是在涂防晒霜的产品，重要的是要清理和维修在上床之前。

正确的方法是：1. 之前清洁的脸，你需要洗手去除菌。 2. 当清洁，你需要洗洗你的脸上有温暖的水，因为水的温度可以影响皮肤的水和石油平衡。 3. 如果你化妆。 弥补去除不可省略，并清洗之后，利用色粉面膜修复。 4. 根据不同类型的皮肤，选择自己的清洁产品。 温和的洁面更适合于夏季。

湿气

夏季高温将导致水的蒸发、以及皮肤更容易发生供水短缺。 适当的水分可以帮助的皮肤维持水石油平衡。 它建议使用喷润或者保湿面罩。 选择一的润肤霜的是适合于自己，它是必要的，以确定皮肤类型和问题，以及皮肤需要经过清洗，以便能够更有效地保湿。

然而，如何选择的化妆品都适合于自己已经成为一个挑战，对大多数女孩。 在商店里，我们经常看到许多女孩感到苦恼，也有许多销售的指导，促进他们的产品。 什么成分的化妆品么我们选择有益于我们的皮肤? 我们都知道，草本植物是纯天然的和非刺激性面临着越来越健康的生活习惯，专家们已经开发出应用程序的相应的成分提取的草本植物在白化和抗衰老化妆品。 成分的植物的提取更温和的效率比，这些合成化学合成。 下面，我们将介绍什么样的植物提取物。

什么是一种植物提取物？

植物提取物是指物质提取的或处理从植物(如全部或它们的一部分)采用适当的溶剂或方法，可以用在医药、食品、日用化学品和其他产业。

为什么选择的植物提取物?

与改善生活标准，人们越来越耐化学合成品和更多的人正在采取更温和的和有效的护肤品。 因此，植物活性物质已经变得越来越重要。 专家们进行实验，对一些植物提取物。 他们不仅强大的基本职能(白，抗老化、抗氧化)，而且还可以有额外的功能，例如舒缓和修复。 只要他们是纯化，公式的稳定性和其他进程，他们是真的不逊色于化学成分! 一个最典型的例子是光甘草定从甘草。

近年来，越来越多的关注，支付给天然植物的提取，市场需求为植物提取物可能经历的显着增长。 在响应这种现象，我们公司的R&D部门已经开发了一系列功能的植物提取的产品：

在短暂的，有时我们可能会忽视它，因为它的名字(诸如各种植物提取物)，但真正的白的功能、安全性和可靠性，因此，仍然依赖于各种数据来证明。 夏天的护肤品是一个基于任务的前提下，炎热的天气并不稳定的温度。 只要温和的和不刺激草产品使用期，并注意到日常照顾和饮食，最佳的皮肤条件能够得到保证。
