Trimethylsiloxy Silicate
What is Trimethylsiloxy Silicate?
Trimethylsiloxy Silicate is a silicone-based polymer formed from trimethylsiloxysilicate and volatile siloxanes, widely used in cosmetics as a film-forming agent. It creates a flexible, breathable film on the skin that enhances product longevity, provides water resistance, and imparts a smooth, matte finish. This ingredient is valued in makeup products like foundations and primers for its ability to adhere pigments without feeling heavy.
