About

A silicone-polymer hybrid conditioning agent that forms a lightweight film on skin and hair, providing smooth feel without heaviness or greasiness.

This crosspolymer combines hydrolyzed silk proteins with PG-propyl methylsilanediol and trimethylsilyl groups to create a sophisticated conditioning film-former. Not listed in EU Annexes II-VI restrictions under Regulation 1223/2009, it is used in leave-on skin and hair care products for its film-forming and conditioning properties. The silicone component provides water repellency while the silk protein adds nutrition and smoothness to the film.

Skin benefits

  • Film-forming for smooth skin feel
