Hydrolyzed Keratin Pg-Propyl Methylsilanediol

What is Hydrolyzed Keratin Pg-Propyl Methylsilanediol?

Hydrolyzed Keratin PG-Propyl Methylsilanediol is a cosmetic ingredient derived from keratin proteins, typically sourced from animal wool or feathers, broken down into smaller peptides through hydrolysis. It is then chemically modified by attaching a PG-propyl methylsilanediol group, a water-soluble silicone derivative, to improve its stability and incorporation into formulations. Primarily used in hair care products like shampoos and conditioners, it belongs to the protein-silicone hybrid category. In formulations, it functions by depositing a lightweight film on hair shafts and skin surfaces, reducing friction, enhancing slip, and promoting a smoother texture without heavy buildup. This modification enhances its substantivity, allowing it to adhere better during rinsing processes, making it suitable for rinse-off and leave-on products targeting conditioning effects.
