Solum Diatomeae ●
TL;DR. This ingredient is used mainly as an absorbent, mild abrasive, anti-caking agent, and texture modifier in powders, masks, scrubs, and some cleansing products.
What does Solum Diatomeae do in a cosmetic formula?
This ingredient is used mainly as an absorbent, mild abrasive, anti-caking agent, and texture modifier in powders, masks, scrubs, and some cleansing products.
Is Solum Diatomeae clean?
Clean-beauty frameworks generally treat it as low concern for topical use, with the main caveat being physical irritation from gritty particles or fine airborne dust. Particle size, purification, and dust control matter more than systemic safety concerns.
Is Solum Diatomeae sustainable?
This material is sourced from naturally occurring sedimentary mineral deposits, so it is non-renewable but typically requires relatively simple physical processing. It is inorganic and does not biodegrade, but it is chemically inert and not associated with bioaccumulation.
Is Solum Diatomeae COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic formulations when sourced and processed according to the standard’s rules for mineral ingredients. Its Green Chemistry profile is strongest on simple processing and low reactivity, weaker on renewable sourcing and biodegradability because it is a mined inorganic material.
How does Solum Diatomeae work chemically?
The molecule is not a single defined molecule, but a porous amorphous mineral matrix with high surface area, giving it strong oil, water, and odor adsorption. It is stable across normal cosmetic pH ranges, insoluble in water and oils, and usually used where opacity, absorbency, slip, or gentle mechanical polishing is needed.
