Cosmetic silica is a type of processed silica with unique forms and properties. Its particle morphology is an irregular polyhedron or fiber like shape, with particle sizes mostly ranging from 0.1 to 10 microns. This form of silica has higher reflectivity and covering power. In the field of cosmetics and other fields, cosmetic silica is used as an efficient optical whitening agent and covering agent, which can effectively improve the color and texture of products.

The spherical, small particle size, and porous properties of silica make it an anti caking agent and thickener in the cosmetics field, which can improve storage stability and dispersion of powdered products, and is widely used.
