Perlite ●
TL;DR. This ingredient is used as a physical exfoliant, absorbent, and texture modifier. Its porous mineral particles can add gentle scrubbing, reduce greasiness, and improve slip in cleansers, masks, and powders.
What does Perlite do in a cosmetic formula?
This ingredient is used as a physical exfoliant, absorbent, and texture modifier. Its porous mineral particles can add gentle scrubbing, reduce greasiness, and improve slip in cleansers, masks, and powders.
Is Perlite clean?
From a clean-beauty perspective, it is generally low concern because it is inert, non-sensitizing, and not a common allergen. Raw airborne dust is the main handling issue for manufacturers, not a typical finished-product concern.
Is Perlite sustainable?
This material is mined, so it is nonrenewable, but it is abundant and mineral-based. It is not biodegradable in the organic sense, yet it is environmentally inert and is often used as a plastic microbead replacement.
Is Perlite COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic frameworks when sourced and processed as an allowed mineral ingredient. Its Green Chemistry profile is strongest on low reactivity and physical processing, with the main caveat being mining and the energy used for expansion.
How does Perlite work chemically?
The molecule is an amorphous hydrated aluminosilicate mineral that becomes highly porous when thermally expanded, which gives it absorbency and a lightweight abrasive feel. Typical use levels vary by format, often around 0.5% to 5% for oil control or texture and higher in rinse-off exfoliating products, and it is insoluble and stable across normal cosmetic pH ranges.
