kaolin Kaolin (China-clay) is a hydrated aluminum silicate crystalline mineral (kaolinite) formed over many millions of years by the hydrothermal decomposition of granite rocks. Hydrous kaolin is characterized by its fine particle size, similar to that of a plate (lamellar particle) and chemical inertness.
The mineral Kaolin has an ancient use as a skincare product. Like other clays, kaolin is very absorbent, and it can pull oils and dirt out of the skin. It is commonly used in clay masks or as an additive to baths to sooth the skin, and it is also included in numerous cosmetics.
