Kaolinite is a type of clay mineral that is primarily composed of aluminum silicate. It is formed through the weathering of rocks, particularly feldspar, and is known for its fine particle size and white color. Kaolinite is commonly used in various industries, including ceramics, paper, and cosmetics, due to its plasticity and ability to retain shape when molded. This mineral is also an important component in the production of porcelain and is valued for its non-toxic properties. Kaolinite can absorb moisture and is often used in products like face masks and toothpaste for its gentle texture and beneficial qualities.
