Application

Bentonite Nanoclay serves multiple purposes across various industries due to its unique properties. As a fine, crystalline, clay-like mineral, it forms a gelatinous suspension when mixed with water, allowing it to be used as an effective adsorbent, particularly in the manufacturing of paper and iron castings. In the pharmaceutical field, Bentonite Nanoclay functions as a suspending agent, helping to stabilize and formulate suspensions, gels, and sols, as well as suspending powders in aqueous preparations and creating cream bases with oil-in-water emulsifying agents. Its strong adsorbing capacity makes it useful in adsorbing cationic drugs to control their release, mask tastes, and as a potential diagnostic agent for imaging applications. Additionally, it finds applications in cosmetics and food products, and is being explored for therapeutic uses, such as adsorbing lithium in cases of poisoning. Bentonite Nanoclay's versatility stems from its composition of hydrated aluminum silicate, enabling its use in diverse fields such as metallurgy, soap manufacturing, and petroleum refining.
