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). It is mainly produced under alkaline conditions, using precipitation process. Uses in in pharmaceutical products, silica aids powder flow when tablets are formed. Silicon Dioxide is an oxide of silicon with the chemical formula SiO2. 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. As a professional Silicon Dioxide supplier, we supply Silicon Dioxide food and pharmaceutical grade.
