Trimethylsiloxysilicate/Dimethicone Crosspolymer
What is Trimethylsiloxysilicate/Dimethicone Crosspolymer?
Trimethylsiloxysilicate/Dimethicone Crosspolymer is a synthetic hybrid polymer formed by crosslinking trimethylsiloxysilicate, a rigid silicone resin, with dimethicone, a soft emollient silicone. Derived from siloxane chemistry, it appears as a clear gel or powder in cosmetic formulations, commonly found in makeup primers, foundations, and powders. It functions by creating a flexible, breathable film on the skin that adheres well, blurs imperfections, and absorbs excess sebum for a matte appearance. As an antifoaming agent, it suppresses foam during manufacturing, aiding efficient mixing and filling. In products, it enhances wear time, improves spreadability, and provides a soft-focus effect without heaviness, making it ideal for long-lasting, comfortable application in oil-control cosmetics.
