Trimethylsiloxysilicate

A film-forming silicone resin that creates long-wearing, water-resistant barriers in cosmetics.

Trimethylsiloxysilicate is a cross-linked silicone resin that forms flexible, breathable films on skin and hair. It provides water resistance and long-wear properties to makeup while maintaining a lightweight feel. In skincare, it helps prevent moisture loss and improves product longevity, particularly in sunscreens and long-wear formulations.
