What It Does
Kaolin is a naturally occurring soft white clay mineral composed primarily of kaolinite (hydrated aluminum silicate), mined from deposits formed by the weathering of feldspar-rich rocks. Prized in cosmetics for its exceptional oil-absorbing properties and gentle nature, it's particularly valued in face masks, dry shampoos, and powder formulations where it provides a silky texture while drawing out impurities and excess sebum without over-drying. Its fine particle size and neutral white color make it ideal for creating smooth, non-irritating formulations suitable even for sensitive skin types.
