Light Kaolin BP
Abstract
Kaolin is Kaolinite is a clay mineral, part of the group of industrial minerals, with the chemical composition Al2Si2O5 (OH)4. It is a layered silicate mineral, with one tetrahedral sheet of silica (SiO4) linked through oxygen atoms to one octahedral sheet of alumina (AlO6) octahedral. Rocks that are rich in kaolinite are known as kaolin or china clay.
Use/Application
Kaolin is widely used cosmetics. Also used as a toothpaste ingredient.
