About

A protein-silicone hybrid that binds to damaged hair and skin, reducing protein loss and improving structural integrity.

Hydrolyzed keratin PG-propyl silanetriol is a silanized hydrolyzate of keratin (derived from feathers or wool) coupled with propylsilane triol groups. The silanetriol moiety allows covalent binding to keratin in hair and skin, improving substantivity. Keratin hydrolyzates are listed in CosIng without EU restrictions and are considered safe. They are widely used in hair care for film-forming and conditioning benefits.
