Polyphenylsilsesquioxane

What Polyphenylsilsesquioxane is & what it does

Polyphenylsilsesquioxane is a silicone-based polymer with a cage- or network-like structure carrying phenyl groups. In cosmetics it acts as a film-forming and skin-conditioning agent that leaves a smooth, even surface and can improve the wear of a product. Its phenyl content gives it a higher refractive index than many silicones, which can lend a soft sheen.
