Mainly polyether silicone surfactants, the combined structure of polysiloxane segment (A) and polyether segment (B) includes block AB type, block ABA or BAB type, and block (AB) 5 types including n-type, branch-chain type and side-chain type. There are two ways to connect the polyether segment and the silicone segment, namely the si-o-c type and the s-c type. The former is unstable and belongs to the hydrolysis type, while the latter is stable to water and is called non-hydrolyzed type.

Using polyether silicone oil with both water solubility, emulsification, surface activity and physiological inertness, it can be formulated into personal protection products to produce colorless, odorless, non-irritating human body, and does not affect the normal breathing and sweating of skin Product. It can also reduce the surface tension of cosmetics, which is conducive to spread on the skin and hair. It has moisturizing and retention properties, makes the hair shiny, antistatic, and has good antibacterial activity. It is an excellent cosmetic additive.
