Australian White Kaolin Clay is a finely textured cosmetic clay composed of kaolin and quartz, commonly used as a base ingredient in clay masks and other skincare formulations. Unlike bentonite clay, kaolin does not swell or thicken in water, so it’s typically suspended in a water-based product using a thickening gel or emulsifier. It provides good coverage and drying capacity, making it a suitable base for layering with more active clays. Typical use levels range from 0.5% to 50%, depending on the formulation. As it’s a dry ingredient added to water-containing products, formulators should re-evaluate preservative efficacy once this clay is incorporated.
