Mechanism of Action
This inert mineral functions through two primary mechanisms: mechanical exfoliation and absorption. Its unique porous structure, composed of fossilized diatoms, enables it to gently abrade the skin surface, facilitating the removal of dead skin cells for a smoother complexion. Concurrently, its high surface area acts as a powerful absorbent, effectively controlling excess oil and delivering a visible mattifying effect.

The Formula
Formulation
Stability
Solum Diatomeae is an inert and highly stable ingredient that does not require intrinsic preservation. While insoluble in both water and organic solvents, it readily disperses in aqueous formulations to form a suspension. Optimal storage conditions involve a dry environment to prevent moisture absorption.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Solum Diatomeae is safe for use in cosmetic products under current practices. Usage concentrations vary significantly depending on product type, observed up to 2% in rinse-off products (e.g., paste masks) and at a lower concentration of 0.01% in leave-on formulations (e.g., nail polishes).
