Calcium Carbonate ●
TL;DR. This ingredient is used mainly as an abrasive, opacifier, absorbent, and bulking powder, especially in toothpaste, powders, masks, and color cosmetics. It can also help adjust texture and reduce shine in anhydrous or powder-based formulas.
What does Calcium Carbonate do in a cosmetic formula?
This ingredient is used mainly as an abrasive, opacifier, absorbent, and bulking powder, especially in toothpaste, powders, masks, and color cosmetics. It can also help adjust texture and reduce shine in anhydrous or powder-based formulas.
Is Calcium Carbonate clean?
From a clean-beauty perspective, it is generally well-tolerated and not a common sensitizer. The main quality considerations are particle size, purity, and dust control in loose powders.
Is Calcium Carbonate sustainable?
This material is typically mineral-derived and abundant, with processing that usually involves mining, milling, and purification rather than complex synthesis. It is not biodegradable in the usual organic sense, but it is an inert mineral with low persistence concern when responsibly sourced.
Is Calcium Carbonate COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic products when it meets the standard’s mineral-origin and processing requirements, though it does not contribute to organic content. Its Green Chemistry profile is favorable because it is abundant, stable, and typically processed with relatively simple physical methods.
How does Calcium Carbonate work chemically?
This compound is an inorganic ionic mineral made of divalent calcium cations and planar carbon-oxygen anions arranged in a crystalline lattice. In toothpaste it is often used at high solid levels as a polishing agent, while in cosmetics its performance depends strongly on particle size, surface treatment, and dispersion quality.
