The surface activity of modified polysiloxane in water phase or oil phase depends on the type and quantity of modifying 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 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 category of products that develop rapidly and deserve attention. Cationic, anionic or nonionic silicone emulsions can be used in the production of cosmetics.
