Silicon Dioxide
Silicon Dioxide
Silicon dioxide (silica) is an inorganic mineral used in cosmetics primarily as an absorbent, anti-caking, bulking, matte-finish, and texture-improving powder. It can help reduce shine, improve flow in pressed powders, and enhance slip and feel in makeup and skincare formulas. In cosmetic safety reviews, amorphous silica is generally considered safe when used as intended and formulated to be non-irritating.

Risks & Warnings
Main concern is inhalation of fine airborne powders during manufacturing or use of loose powders; crystalline silica is a known respiratory hazard, but cosmetic uses are typically amorphous silica. Can be drying in very high-powder systems or on already-dehydrated skin. ([pubchem.ncbi.nlm.nih.gov](https://pubchem.ncbi.nlm.nih.gov/compound/Silica?utm_source=openai))
