Abstract (EN): The clay minerals have layered crystal structure, they are part of the mineral group called phyllosilicates. They have chemical composition and physical and physico-chemical properties different, such as colloidal size less than 2¿m, high specific surface area, sorption and ion exchange capacities, pleasant sensation when applied to skin, and plastic and thixotropic characteristics. Because of this they are suitable to be used in topical products. In fact, their properties were already known and exploited since prehistoric times with reports of its use in the treatment of wounds and as for cleaning the skin. This review paper emphasizes the importance of these minerals in use in cosmetics, which can perform various functions, both as an excipient or as an active component, and have been included in numerous products, such as skin care emulsions, facial masks, sunscreens, cleansers skin, shampoos and makeup products. The increase over recent years in the use of natural products, associated with a greater awareness of the need to preserve the environment, it has attracted increasing interest in clay minerals. Brazil, as a holder of one of the world¿s largest reserves from clay has the third biggest depository of patents in this area. Considering the wide potential use of clay minerals, it can be stated they are great opportunities for research and development of new cosmetic products.
