How we scored it

Synthetic monoazo dye from dichlorophenyl-diazonium coupled to a dimethoxyphenyl-naphthalene-carboxamide, all petrochemical aromatics; 0/496 = 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

Manufactured by diazotizing a chlorinated aniline and coupling it to a naphthol-carboxanilide, both derived from petrochemical aromatics. No natural alternative route exists for this colorant.

In plain English

A synthetic azo colorant used to add colour to cosmetic products. It's manufactured entirely from petrochemical aromatic chemicals and has no natural source.

CosIng definition: CI 12480 is classed chemically as a monoazo colour. It conforms to the formula:
