West Australian Diatomaceous Earth 

Diatomaceous Earth (DE) or Diatomite is a sedimentary rock composed of diatoms, that formed in a freshwater lake over thousands of years. Diatoms are opaline silica skeletal remains of microscopic, photosynthetic algae. Compared to other Australian DE deposits, our West Australian DE is unique since it was formed more recently during the Pleistocene to Recent Ages. This results our West Australian DE naturally has a higher amorphous silica content. Amorphous silica is more soluble than crystalline silica and is not a health hazard.


Our West Australian DE’s diatoms are also distinctly “boat shaped”.
