Silicon Dioxide, E551, CAS no.7631-86-9, white powder. Silicon dioxide (SiO2), also known as silica, is a natural compound made of two of the earth’s most abundant materials: silicon (Si) and oxygen (O2). Silicon Dioxide is a common additive in the production of foods, where it is used primarily as a flow agent in powdered foods, or to absorb water in hygroscopic applications used in silica gel, control moisture levels to avoid prevent certain goods from going bad. It is often used in cheese, fat spreads, confectionery, dried vegetables, etc.
