According to the connection mode between the polyether segment and the siloxane segment, it is further divided into: Si-O-C type and Si-C type. Si-O-C type polyether modified polysiloxane is mostly obtained by the condensation of alkoxy silicone oil and hydrocarbon-terminated polyether. It is prone to hydrolysis and breakage when acid and alkali are present, and it is a hydrolyzed type. It is mainly used as a degradable surfactant. Si-C type is mostly obtained by the hydrosilylation reaction of oxygen-containing silicone oil and allyl polyether. It has good chemical stability, is not easy to hydrolyze, and has good stability. It can be stored for a long time in the air, and is called non-hydrolyzed type.

CHUNG et al. Prepared twelve grafted silicone surfactants by hydrosilylation, and studied the effect of the size of Si-O-Si chain links on their surface properties, and found that Si-O-Si chain links The influence of the size on the surface tension of the grafted silicone surfactant is greatest.

This product has good compatibility with ethanol, stearyl alcohol, and fatty acids. Its foamability is comparable to other non-ionic surfactants. It is compatible with sodium lauryl sulfate (K12) and fatty alcohol polyoxyethylene. Anionic surfactants such as sodium ether sulfate (AES) have a complex coordination effect, which can reduce their irritation to the skin and eyes. Used in shampoos, not only does not affect the shampoo's foam properties, it can even increase and improve the stability of the foam. After shampooing, it can significantly improve the wet and dry combing of the hair, and reduce the flying of the hair due to its antistatic properties. Polysiloxane polyether copolymers with long-chain alkyl groups are very effective W / O emulsifiers not only for polysiloxane liquids but also for mineral oils or vegetable oils with high protein content. It can also produce stable pastes under high temperature or freezing conditions. If it has a suitable HLB value, it can be used as an effective W / O emulsifier with cyclosiloxane to prepare a sweat and deodorant.
