Diatomaceous Earth is not earth or dirt. It is the fossilized remains of Melosira Preicelanica, microscopic one-celled aquatic plants. As these diatoms fossilized they retained their tubular shape and holes. Their shape and hardness produces DE that is extremely pure and consistent.
This is amorphous silica in its naturally occurring state. It is from one of the four out of 600 DE deposits rated Chemical Codex Food Grade by FDA standards.
Ingredients: 100% Pure fresh water Diatomaceous Earth, mined naturally milled ad bagged in the United States. It is unheated amorphous (non-crystalline) silicon dioxide.
