According to Wikipedia

“Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled algae. It is used as a filtration aid, mild abrasive in products including toothpast, mechanical insecticide, absorbent for liquids, matting agent for coatings, reinforcing filler in plastics, and rubber, anti-block in plastic films, porous support for chemical catalysts, cat litter, activator in blood clotting studies, a stabilizing component of dynamite, and a thermal insulator”
