How we scored it
Cu3(CO3)2(OH)2: Cu2+ (natural metal ion) + carbonate + hydroxide (both natural mineral anions) — every fragment natural origin → 1.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Mined copper carbonate hydroxide mineral, ground for cosmetic colorant/conditioning use. No synthetic route is used commercially; sourced by mining.
In plain English
A natural deep-blue copper carbonate mineral, ground for use as a colorant in cosmetics. Mined directly from rock, not made in a lab.
CosIng definition: Azurite is a mineral consisting chiefly of basic copper carbonate
