Clay Minerals
What is Clay Minerals?
Clay minerals encompass a group of naturally occurring hydrated aluminum silicates, including kaolin, bentonite, and montmorillonite, formed from weathered rocks or volcanic activity. Mined from deposits around the world, they are milled into fine powders for cosmetic use. Primarily featured in face masks, cleansers, and exfoliants, these ingredients function as absorbents by drawing out excess sebum and surface debris through adsorption. Their platelet structure swells with water, enhancing viscosity and providing a creamy texture. Additionally, they act as opacifying agents to improve product appearance and bulking agents for formulation stability. Purified to remove impurities, clay minerals offer a gentle mechanical cleansing action suitable for topical applications.
