Application
Bentonite is a versatile crystalline clay mineral known for its wide range of applications due to its unique properties. It appears as an odorless, fine powder in various off-white to grayish shades and is recognized for its ability to swell when wet, particularly in its sodium form. The primary purpose of bentonite is as a general-purpose additive across various industries. In the food industry, it serves as a clarifier and stabilizer for wine. In papermaking, it acts as an adsorbent, and in iron casting, it is used to bind sand into moulds. Bentonite is also significant in the pharmaceutical and cosmetic industries, where it is employed in formulating suspensions, gels, and emulsifying agents for topical applications. Its strong adsorbing capacity makes it valuable in metallurgy, soap manufacturing, and petroleum refining, where it functions as a decolorizing agent. Additionally, bentonite has been studied for its potential therapeutic applications, such as adsorbing and moderating the release of drugs in oral preparations or being used in diagnostic imaging technologies.
