How we scored it

MW 452.4: 2xSO3Na=206.12 mineral-natural; remaining phenyl-diazo-naphthol backbone 246.28 petrochemical -> 206.12/452.4=0.46.
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

Made by diazotising aniline (petrochemical) and coupling with a naphthol disulfonic acid. No natural production route exists.

In plain English

A synthetic azo dye used to colour cosmetic products, built from petrochemical aniline and naphthol chemicals bearing sulfonate salt groups. Not naturally sourced.
