How we scored it
Elemental carbon (graphite); formula C matches CosIng description. The supplied iupac field 'methane' contradicts the description and is a data error, ignored per instruction to trust the description.
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
Cosmetic-grade graphite is typically natural mined and purified mineral flake. A synthetic, petroleum-coke-derived graphite also exists but is not typical for cosmetic colorant use.
In plain English
A natural mineral form of carbon used as a dark colorant in makeup like eyeliner. Mined, purified graphite rock.
CosIng definition: Graphite is a crystallized form of carbon.
Structure
methane
