AMODIMETHICONE/SILSESQUIOXANE COPOLYMER.

Valuable CAS 67923-07-3 / FILM FORMING, HAIR CONDITIONING, HAIR FIXING

A hybrid silicone polymer that combines amino-modified silicone with three-dimensional resin technology to create durable, breathable films on skin. This advanced copolymer delivers superior conditioning properties while maintaining excellent sensory characteristics across diverse formulation types.

Summary

emollient film former skin conditioning texture enhancer

Science

Mechanism of Action

Creates a cationic charge affinity for keratin surfaces through its amodimethicone component, while the silsesquioxane structure forms a three-dimensional network that produces breathable, non-tacky films that smooth texture and enhance moisture retention
