Diatomaceous Earth, often referred to as DE, is a naturally occurring, porous sedimentary rock composed of the fossilized remains of diatoms, a type of microscopic algae. Its chemical formula is primarily SiO2 (silicon dioxide), with traces of other minerals. In cosmetics, Diatomaceous Earth is used for its gentle exfoliating properties and absorbent qualities. It appears as a fine, soft, chalky powder and serves as an effective yet non-abrasive exfoliant, aiding in the removal of dead skin cells, impurities, and excess oil. Additionally, Diatomaceous Earth can be found in products like facial masks and scrubs, contributing to smoother and revitalized skin.
Origin
Diatomaceous Earth is formed over millions of years from the accumulation of the silica-rich cell walls of diatoms, tiny aquatic algae. These diatoms die, sink to the ocean or lake floor, and their remains fossilize. The deposits are then mined, crushed, and milled to produce the fine, powdery substance used in cosmetics.
Safety profile
Diatomaceous Earth has a favorable safety profile when used in personal care and cosmetic products. It is non-toxic when applied topically and generally well-tolerated by most skin types. However, as with any cosmetic ingredient, individuals with specific sensitivities or allergies should exercise caution and conduct a patch test.
