Gypsum ●
TL;DR. This ingredient is used mainly as an absorbent, opacifying mineral, and bulking agent in powders, masks, color cosmetics, and some cleansing or dental formats. It can also add mild abrasion and help adjust product texture.
What does Gypsum do in a cosmetic formula?
This ingredient is used mainly as an absorbent, opacifying mineral, and bulking agent in powders, masks, color cosmetics, and some cleansing or dental formats. It can also add mild abrasion and help adjust product texture.
Is Gypsum clean?
This ingredient is generally low-irritation and is not a common cosmetic allergen or a typical clean-standard restricted-list material. In loose powders, the main practical concern is mechanical dust irritation from inhalable particles rather than skin sensitization.
Is Gypsum sustainable?
This material is an abundant mined mineral, so its footprint is tied mostly to quarrying, transport, and particle processing. It is inorganic, not meaningfully biodegradable, but it is not expected to bioaccumulate and is environmentally familiar as a naturally occurring mineral salt.
Is Gypsum COSMOS-approved?
It is permitted in COSMOS-natural and COSMOS-organic products when it meets the standard’s mineral-ingredient requirements and processing limits, with no organic content contribution. From a Green Chemistry view, it scores well for low chemical processing and inertness, though it is non-renewable and not assessed like biodegradable organic ingredients.
How does Gypsum work chemically?
The material is an inorganic hydrated salt lattice made of calcium cations, sulfate anions, and bound water in a fixed crystalline structure. It is only sparingly soluble in water, roughly a few grams per liter at room temperature, is generally stable across normal cosmetic pH ranges, and can change hydration state under significant heat.
