Bentonite powder is a naturally occurring, highly absorbent clay-like substance derived from volcanic ash. It is composed primarily of montmorillonite, a mineral that is known for its ability to absorb water and other liquids. Bentonite powder is commonly used in a variety of industries, including construction, drilling, and cosmetics, due to its unique properties such as its ability to swell and form a gel-like substance when it comes into contact with water, making it useful as a binding, thickening, and clarifying agent.
