Kaolinite

What is Kaolinite?

Kaolinite is a fine, white, layered silicate mineral primarily composed of aluminum, silicon, and oxygen, formed through the weathering of feldspar in tropical environments. As a key ingredient in cosmetics, it belongs to the category of absorbent clays commonly found in face masks, cleansers, and powders. Its porous, platelet-like structure enables it to adsorb oils, toxins, and dirt from the skin's surface, promoting a smoother texture while delivering a mild mattifying effect. In formulations, kaolinite acts as a bulking agent to improve product consistency, an opacifier for visual appeal, and a protective barrier that soothes minor irritations without harsh abrasion. Dermatological reviews affirm its suitability for frequent use in rinse-off and leave-on products due to its inert nature and minimal reactivity.
