Diatomaceous earth powder is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder. It consists of the fossilized remains of diatoms, a type of microscopic algae with silica-rich cell walls. Diatomaceous earth powder is known for its abrasive and absorbent properties. It is used in various applications, including as a natural insecticide in agriculture and pest control, where its sharp particles damage the exoskeletons of insects, causing dehydration. It also serves as a filtration aid, a mild abrasive in cleaning and personal care products, and a food additive for its anti-caking properties. Additionally, it is used in industrial applications such as paint and rubber manufacturing.
