Application of cationic silicone surfactants in daily chemicals 1-Cosmetic silicone oil manufacturer

When the hydrophilic group contains structural units such as quaternary ammonium salt, imidazole salt, pyrrole salt, and pyridinium salt, it is a cationic silicone surfactant. In particular, quaternized polysiloxane is the best conditioner for hair care. Generally, the addition reaction of epoxy silane and tertiary amine, the substitution reaction of hydrocarbyl silane and tertiary amine, the quaternization reaction of aminosilane and the ring-opening reaction of aminosilane and epoxy compound are used to prepare the quaternary ammonium salt type silicone surface. active agent. MEHTA and others use the quaternary ammonium salt type silicone surfactant prepared by the above method. This product has excellent performance.

BAUER et al. synthesized a cationic trisiloxane surfactant, studied its surface activity, and found that this type of cationic silicone surfactant can reduce the surface tension of water to 21 mN/m at 1.0% (mass fraction) , and it is believed that cationic silicone surfactants have good bactericidal properties and metal anti-corrosion properties.
