Question 1

What does Diatomaceous Earth/Solum Diatomeae/Terre De Diatomées do in a cosmetic formula?

Accepted Answer

This ingredient is used as an absorbent, mild abrasive, opacifier, and anti-caking powder in products such as masks, cleansers, toothpastes, deodorants, and dry shampoos.

Question 2

Is Diatomaceous Earth/Solum Diatomeae/Terre De Diatomées clean?

Accepted Answer

Clean-beauty frameworks generally view it as a low-reactivity mineral material, with the main caveat being airborne dust and possible crystalline mineral impurities in poorly controlled grades. Cosmetic-grade material is expected to be refined and specified for low respirable crystalline content.

Question 3

Is Diatomaceous Earth/Solum Diatomeae/Terre De Diatomées sustainable?

Accepted Answer

This material is mineral-derived and obtained by mining, so its footprint depends on quarry practices, processing energy, and dust controls. It is not biodegradable in the organic sense, but it is inert and not associated with bioaccumulation in normal cosmetic use.

Question 4

Is Diatomaceous Earth/Solum Diatomeae/Terre De Diatomées COSMOS-approved?

Accepted Answer

It is generally compatible with COSMOS when sourced as an approved mineral and processed only by permitted physical methods, though it cannot contribute organic content. From a Green Chemistry view, it scores well for inertness and simple processing, but less well on renewability because it is mined rather than grown.

Question 5

How does Diatomaceous Earth/Solum Diatomeae/Terre De Diatomées work chemically?

Accepted Answer

The material is a porous, fossil-derived mineral powder composed mainly of amorphous hydrated silicon dioxide with a high surface area, which explains its oil absorption and gentle scrubbing behavior. It is chemically stable across typical cosmetic pH ranges and is usually formulated as an insoluble powder, with inhalation exposure and particle-size control being the key formulation considerations.
