Activated Bentonite Clay is natural bentonite clay that has been chemically treated—usually with acid (HCl, H₂SO₄) or sometimes with alkali or thermal activation—to enhance its adsorption, bleaching, and purification abilities.

It is also known as: Activated bleaching earth, Acid-activated bentonite, Activated fuller’s earth.
