Chapter 11: Cosmeceutical Applications of Clay Minerals

Clay is a crucial cosmetic product that has been used in products such as hair products, commercial face masks, toothpaste, personal lubricants, sunscreens, various makeup products, and nail polish. The major effect of these clay minerals is in protection against the sun’s radiation, which increases their usage in cosmeceutical products. Various literature studies have reported potential biological activities, i.e., anti-aging, cleaning, preventing wrinkles, and sun protection. Some of the major clays, such as talc, kaolinite, mica, and some smectites, are routinely used in cosmetic products. In addition to these, various other phyllosilicates and modified or synthetic forms are used. For centuries, these clay minerals have been used as a natural remedy against various health conditions. Protection against radiation from the sun by clay particles and decorative effects complete the possibilities of clays in cosmetics. The present chapter specifically covers the historical and present-day uses of clays and also the marketed products that use clays in their product formulations.
