The Scenario of Clays and Clay Minerals Use in Cosmetics/Dermocosmetics

Abstract

The use of clays in beauty care comes from ancient times, with therapeutic use since prehistory, and it is considerably relevant in the current cosmetic industry worldwide. In our review, we described types of clay and clay minerals used in cosmetics and dermocosmetics, compositions, usages as active compounds and cosmetic ingredients/starting materials, and observations about formulation techniques. From this review, we observed that although much scientific and specialized literature has reported the characterization of clays, only some involved efficacy tests when incorporated into cosmetic products, mainly concerning haircare applications. Our review could be considered and encouraged in the coming years to provide scientific and technical information for the cosmetic industry regarding the multifunctional use of clays and clay minerals.
