Diatomaceous earth is generally formed from silicate remains after the death of single-cell algae collectively known as diatoms, whose essence is aqueous amorphous SiO2. Diatoms can survive in fresh water and salt water. There are many kinds of diatoms, which can be generally divided into "central order" diatoms and "feathery order" diatoms. In each order, there are many "genera", which are quite complex.

The main component of natural diatomaceous earth is SiO2. The high-quality ones are white in color, and the SiO2 content often exceeds 70%. Monomer diatoms are colorless and transparent. The color of diatomite depends on clay minerals and organic matter. Diatomite from different mineral sources has different components. Diatomite is a fossil diatom deposit formed after the death of a single-cell plant called diatom and the accumulation period of about 10000 to 20000 years. Diatoms are one of the first protozoa to appear on the earth, living in sea water or lake water.

Diatomite is used in cosmetics and skin care products (beauty and skin care)

Diatomite can be used as the main material of cosmetics and skin care products such as facial mask. Diatomite facial mask mainly uses the adsorption property of diatomite to adsorb substances in the skin and play a role in caring for the skin.
