Diatomaceous Earth, also known as "DE" or "DE powder", or diatomite and kieselguhr consists of the tiny micrscopic biogenic skeletons of millions of the unicellular plants known as diatoms. Over 5 million years massive deposits were left in freshwater lakes which covered much of what is now Nevada and eastern Oregon.
Today DE has so many varied uses. It's a filtration media to filter liquids such as wine, beer, water, and specialty chemicals. It's also a useful functional additive in products such as soaps, paint, plastics, rubber, and even insecticides. It is used as a natural absorbent for cat litter and floor dry, and as a source of silica in calcium and other silicates.
Our DE powder is not food grade. It is suitable as an additive in many applications and products.
