Brown kaolin clay or Chinese clay owes its name to its place of origin, the Kao-ling mountain. The place from where it is extracted, crushed and dried, resulting in a fine powder. Its main composition is kaolinite, rich in silica, which gives it moisturizing, antibacterial and purifying properties. Brown kaolin clay is considered an excellent natural preservative, which makes it a great ingredient in natural cosmetics, as it accumulates water, preventing the formation of microorganisms.
