Silica for toothpaste is white powder. It is a porous substance. Its composition can be expressed as SiO2·nH2O, where nH2O exists in the form of surface hydroxyl groups. It is soluble in caustic alkali and hydrofluoric acid, but insoluble in water, solvents and acids (except hydrofluoric acid). It is resistant to high temperatures, non-flammable, tasteless, odorless, and has good electrical insulation.
