Polymethylsilsesquioxane/Silica Crosspolymer
What is Polymethylsilsesquioxane/Silica Crosspolymer?
Polymethylsilsesquioxane/Silica Crosspolymer is a lab-made hybrid ingredient blending silica, an inorganic silicon dioxide, with polymethylsilsesquioxane, a flexible organosilicon polymer, through a crosslinking process. This creates porous, microspherical particles commonly found in makeup primers, foundations, powders, and select skincare items like mattifying gels. In products, it works by trapping excess oils within its structure for shine control, scattering light to visually smooth skin texture, and providing a silky glide that improves blendability. Its solid, non-melting form ensures stability across various formulas, contributing to a lightweight, velvety sensory experience without greasiness.
