Diatomaceous earth /ˌdaɪ.ətəˌmeɪʃəs ˈɜrθ/, also known as D.E., diatomite, or kieselgur/kieselguhr, is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder. It has a particle size ranging from less than 3 micrometres to more than 1 millimetre, but typically 10 to 200 micrometres. Depending on the granularity, this powder can have an abrasive feel, similar to pumicepowder, and has a low density as a result of its high porosity. The typical chemical composition of oven-dried diatomaceous earth is 80 to 90% silica, with 2 to 4% alumina (attributed mostly to clay minerals) and 0.5 to 2%iron oxide.

Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled algae. It is used as afiltration aid, mild abrasive in products including metal polishes and toothpaste, mechanical insecticide, absorbentfor 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.

 

Is Diatomaceous Earth Harmful To Pets?

Diatomaceous Earth is 100% Natural Fresh water Siliceous Fossil Flour. Siliceous fossil flour as it’s known, was used very effectively for about one hundred years before chemical pesticides were introduced. Since chemical pesticides tend to leave residue in our food supply and poison the heck out of mammals, bees, fish and any wildlife they come in contact with, Siliceous fossil Flour is back in fashion in agricultural circles as it does not contain any toxic chemical.

Diatomaceous Earth is a completely organic product, derived from the fossilized remains of Diatoms, a type of hard-shelled algae. Diatoms are phytoplankton, a food source for freshwater and marine animals. When they die, their skeletons settle to the ocean or lake floor and over time become thickly fossilized deposits. These deposits are mined and milled and sold as various grades for industrial and agricultural applications.

Diatomaceous Earth is very dusty and can cause lung problems if breathed heavily, so when applying it dry always wear a good dust mask. Also wash your hands with water after application as it can leave hand dry.
