Cosmetic surfactants are newly developed in recent years. They have higher and stricter requirements for products, such as anti-aging, skin moisturizing, wrinkle removing, whitening and so on. The active ingredients of cosmetics affect the metabolism of the body after being absorbed by the skin to achieve real beauty. The effect should be felt or seen. Sodium pyrrolidone carboxylate (PCA) is a natural moisturizing factor of cosmetics, which has the effects of anti-aging and wrinkle removal. Therefore, PCA is widely used in high-grade cosmetics. Surfactants as emulsifiers are very important in the emulsion application of cosmetics, mainly focusing on non-ionic surfactants and polymer emulsifiers. Cosmetic emulsions include double emulsions; W / O, O / W, liquid crystal phase, multiple emulsion; W / O / W, O / w / O, microemulsion, etc. The main products are facial cleanser, moisturizer, cleaning milk, etc. There will be new products coming out in this field.

Surfactants are a large class of substances. According to statistics, there are more than 1000 kinds. In the future, new varieties will be developed, and more than 150 kinds are commonly used. They are closely related to our lives, affecting and changing our lives.

The classification code of sodium tripolyphosphate is gbl5.003, ins451 (I). Chemical structure: This product is a kind of amorphous water-soluble linear polyphosphate, terminated with na2po4 at both ends, chemical formula na5p3 O10, relative molecular weight 367.86. It is commonly used in food as water retention agent, quality improver, pH regulator and metal chelator.

Surfactant not only brings great convenience to people's life and industrial and agricultural production, but also pollutes our environment. This is a worldwide problem, especially in China. The solution is related to whether China can take the road of sustainable development. According to relevant reports, water pollution in China's rivers and lakes, such as Huaihe River, Liaohe River, Songhua River, Chaohu Lake, Taihu Lake and Dianchi Lake, has directly affected people's lives. Among them, the pollution of Dianchi Lake has been proved to be caused by the extensive use of phosphorus containing detergent by residents, the water quality is seriously eutrophic, and the clear and transparent lake water becomes black and smelly. Sodium tripolyphosphate (na5p3o10) is a common detergent aid. It can form water-soluble complexes with calcium, magnesium and iron plasma to soften water. It can also have a strong buffer effect in the range of pH = 4.3 ~ 14, adjust pH value and ensure washing effect. If it is not for pollution, it is an ideal detergent. In order to change this situation, the environmental protection department has taken measures to limit the production and sales of phosphorus containing detergents.
