Fuller's earth is a term for various clays used as an absorbent, filter, or bleaching agent. Products labeled fuller's earth typically consist of palygorskite (also known as attapulgite) or bentonite.[1] Primary modern uses include as absorbents for oil, grease, and animal waste (cat litter), and as a carrier for pesticides and fertilizers. Minor uses include filtering, clarifying, and decolorizing;[1][2] as an active and inactive ingredient in beauty products; and as a filler in paint, plaster, adhesives, and pharmaceuticals.[1] It also has a number of uses in the film industry and on stage.
