What is Kaolin?

Kaolin (also called china clay or white clay) is the gentlest of the cosmetic clays — a hydrated aluminium silicate with mild oil-absorbing properties. Unlike bentonite, kaolin doesn't swell aggressively on contact with water, which makes it suitable for sensitive and combination skin types that find bentonite over-drying.
