How we scored it

Synthetic disazo colorant; aromatic diazo/coupler rings from petrochemical aniline/phenol precursors, no natural fragment. 0/669 = 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 21230 is made by diazotising a petrochemical aromatic amine and coupling it to a cyclohexylphenol derivative; both precursors originate from crude-oil aromatics. No alternative natural route exists for this synthetic colorant.

In plain English

A synthetic dye used to add colour to cosmetic products. It's manufactured in a lab from petroleum-derived building blocks rather than extracted from a plant or mineral.

CosIng definition: CI 21230 is classed chemically as a disazo colour. It conforms to the formula:
