Silica Dimethyl Silylate is a modified form of silica, a mineral, where its surface has been treated with dimethyl silyl groups. This modification makes it hydrophobic (water-repellent) and gives it excellent thickening and gelling properties. It is often used in cosmetics to create stable, non-greasy formulations and to provide a matte finish.
