How we scored it

Synthetic monoazo pigment with chlorodimethoxyphenyl, diethylsulfamoyl-methoxyphenyl and hydroxynaphthalene-carboxamide fragments; all aromatic rings and the sulfonamide group are petrochemical.
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 12490 is a synthetic monoazo pigment (a chloro-dimethoxyphenyl azo naphthol carboxamide with a diethylsulfamoyl group) manufactured from petrochemical aromatic intermediates. No natural-origin production route exists for this dye class.

In plain English

A synthetic red-orange pigment used as a cosmetic colorant. Built from petroleum-derived aromatic chemicals in a multi-step factory synthesis, with no natural equivalent.

CosIng definition: CI 12490 is classed chemically as a monoazo colour. It conforms to the formula:
