What is DE?

DE is an abbreviation of the words "Diatomaceous Earth," which is a fossilized deposit of microscopic shells created by one celled plants called Diatoms. These plants inhabit all the waters of the earth, and serve as the basic food for aquatic life, just as grass is the basic food for land animals.

Some of these deposits, shifted to dry land, are extremely important to humans. PERMA-GUARD, INC., markets the material as an animal food additive, and, with the addition of Pyrethrum, as a line of environmentally safe insecticides.

What is Codex or "Food Grade" Diatomaceous Earth?

For D.E. to be called "Codex," it must meet the following requirements:

Item Requirement Perma-Guard Results
Arsenic (ppm) not more than 10 ppm
Lead (ppm) not more than 10 ppm
Non-Siliceous Substance % not more than 25% on dried basis
