Silicone surfactants are a large amount of surfactants in the daily chemical industry and can be used in various cosmetics. They are used as emulsifiers in flavors and shampoos and have the functions of emulsification, foaming, dispersion and solubilization. It can make shampoo foam rich, fine and stable, and have antistatic effect. Silicone surfactants have no side effects on the human body and can form a protective film of fat layer on the skin surface to prevent skin dryness. They are excellent skin lubricants and moisturizers and are especially suitable for formulating emulsifiers and emulsion stabilizers for facial and eye cosmetics. . At present, polyether silicone is widely used. Utilizing polyether silicone oil that has the characteristics of water solubility, emulsification, surface activity and physiological inertness, it can be mixed into personal protective equipment to produce colorless, odorless, non-irritating to the human body, and does not affect the normal breathing and normal breathing of the skin. Sweating skin care products can also reduce the surface tension of cosmetics, which is beneficial to diffusion on the skin and hair. It has moisturizing and retention properties, gives hair luster, is antistatic, and has good antibacterial properties. It is an excellent cosmetic aid. agent, and its role is becoming more and more prominent, it has become a type of product that is developing rapidly and deserves attention.
The surface activity of modified polysiloxane in the water phase or oil phase depends on the type and number of modifying groups. Oil-soluble polysiloxane can improve the diffusion ability of oil and paraffin, and can be directly applied to cosmetics and skin care product formulations; modified hydrophilic polysiloxane can mainly be used in the formulation of shampoos and foam solutions. 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 type of product that is developing rapidly and deserves attention. Cationic, anionic or nonionic silicone emulsions can be used in the production of cosmetics.
