How we scored it

Synthetic disazo pigment; bis-dichlorophenyl-diazo-acetoacetanilide, entirely petrochemical aromatics. 0/726 = 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 20040 is a synthetic bis-azo pigment made from petrochemical dichloroaniline and an acetoacetanilide coupler, both derived from crude-oil aromatics.

In plain English

A synthetic colour additive used to tint cosmetic products. Made entirely in a lab from petroleum-derived chemicals.

CosIng definition: CI 20040 is classed chemically as a disazo colour. It conforms to the formula:
