Namely
Kaolin is a white clay composed of aluminum silicates. It goes into the manufacture of paper or porcelain. The clay can be used in cosmetics as an active ingredient or as a white dye (CI 77004). Kaolin is used to relieve sensitive skin, keep white teeth, absorb and regulate excess sebum or fight against perspiration. Kaolin is allowed in organic.
Note that the CIR (American) has opened a new consultation (re-evaluation) of kaolin in May 2018.
