How we scored it
Bone black: carbon, calcium phosphate and calcium carbonate from calcined animal bone, all natural or mineral: 1.00.
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
Dominant route is calcining animal bones in the absence of air to give bone char. The pigment is animal-derived, which matters to vegan users.
In plain English
A black pigment (bone black) made by heating animal bones until they char. It is mostly carbon with calcium phosphate and calcium carbonate, and is used as a colourant in make-up.
CosIng definition: CI 77267 is classed chemically as an inorganic color. It consists primarily of a mixture of carbon, calcium phosphate and calcium carbonate.
