Silicone surfactant is a large amount of surfactant in the daily chemical industry. It can be used in various cosmetics. It is used as an emulsifier in essence and shampoo. It has the characteristics of emulsifying, foaming, dispersing and solubilizing. It can make the shampoo foam rich, fine and stable, and has an antistatic effect. Silicone surfactants have no side effects on the human body, and can form a protective film of the fat layer on the skin surface to prevent skin drying. It is an excellent skin lubricant and moisturizing agent, especially suitable for the preparation of facial and eye cosmetics. . At present, the most widely used is polyether silicone. Using polyether silicone oil with the characteristics of water solubility, emulsification, surface activity and physiological inertness, it can be formulated into personal protection products to make it colorless, odorless, non-irritating to the human body, and does not affect the normal breathing of the skin. Sweaty skin care products, it can also reduce the surface tension of cosmetics, which is conducive to spreading on the skin and hair, has moisturizing and retention properties, imparts luster to the hair, antistatic, and has good antibacterial properties. It is an excellent cosmetic aid. It has become a fast-growing and highly valued product.

The surface activity of modified polysiloxane in water or oil phase depends on the type and number of modified groups. Oil-soluble polysiloxane can improve the diffusion ability of oil and paraffin, and can be directly applied to the formulation of cosmetics and skin care products; modified hydrophilic polysiloxane can be mainly used in the formulation of shampoo and foam solution. In addition to the above-mentioned silicone surfactants, long-chain alkyl-modified polysiloxanes, polysiloxane sulfonates, polysiloxane thiosulfates, and aminosiloxanes have also been used in cosmetics. The role of polysiloxane surfactants in daily cosmetics is becoming more and more prominent, and it has become a class of product
