How we scored it

Synthetic monoazo pigment; methoxy-nitrophenyl-diazo-acetoacetanilide, entirely petrochemical aromatics. 0/370 = 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 11725 is a synthetic azo pigment made from petrochemical aromatic amine and anilide coupler precursors, both derived from crude-oil aromatics.

In plain English

A synthetic colour additive used to tint cosmetics. Manufactured in a lab from petroleum-derived chemicals rather than a natural pigment source.

CosIng definition: CI 11725 is classed chemically as a monoazo colour. It conforms to the formula:
