Anionic silicone surfactants include carboxylic acid type, sulfonic acid type, sulfate ester type and phosphate ester type, which can be obtained by the hydrosilylation reaction of corresponding esters with unsaturated bonds and hydrogen-containing silicone oils, or by epoxy Base intermediate conversion. Phosphate silicone surfactants are the most common. The product is made by phosphorylation of siloxanol, and then neutralized and refined as needed. Polysiloxane phosphate ester not only has the emulsification, foaming, and mild washing properties of phosphoric acid group, but also has non-ionic properties such as the cloud point of polyether, and also has the affinity of polysiloxane for skin and hair. It can be used as a high-efficiency W/O emulsifier, solubilizer, water-soluble foaming agent, detergent, emollient and hair conditioner in cosmetics. Polysiloxane phosphate ester surfactants have emulsifying properties and also have moisturizing functions. They are mainly used in moisturizing skin care products and conditioning hair care products. In hair care products, phosphate ester can delay the accumulation of static electricity and accelerate the discharge. Polysiloxane has a good affinity and conditioning for the skin and hair, so it can improve the dry and wet combability of the hair.
