Bentonite is a type of clay formed from volcanic ash that has unique properties, making it useful in various applications. It is primarily composed of the mineral montmorillonite, which gives it the ability to absorb water and swell. This characteristic allows bentonite to be used in products like cat litter, drilling mud, and as a sealant in construction. In addition to its industrial uses, bentonite is also found in some personal care products, such as face masks and creams, due to its ability to absorb oils and impurities. Its natural origin and versatility make it a popular choice in both commercial and household applications.
