How we scored it

Monoazo pigment from aromatic amine + naphthol diazo coupling; entire carbon skeleton is petrochemical (benzene/naphthalene derivatives). 0/total = 0.0.
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

CI 12085 is manufactured by diazotising a synthetic aromatic amine and coupling it with a naphthol, both derived from petrochemical aromatics. There is no commercial natural-origin route to this pigment.

In plain English

A synthetic red colorant used to tint cosmetics like lipstick and nail polish. It is manufactured entirely from petroleum-derived chemicals through a dye-making reaction and is not extracted from nature.

CosIng definition: CI 12085 is classed chemically as a monoazo colour. It conforms to the formula:
