Origin
Free silica or silicon dioxide is very abundant in nature, in various forms. However, the silica used in cosmetic formulations is almost all of synthetic origin. Synthetic silicas are made of high purity silicon dioxide. Pyrogenic silicas like silica silylate and silica dimethyl silylate are produced by a combustion process, which leads to spherical particles of nanometric size. They are formed by pyrolysis from SiCl4 to 1000°C.
