How we scored it

Aromatic diaminobenzoic acid built entirely on a petrochemical benzene ring → 0/152.15 = 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 nitration and reduction of a petrochemical benzoic-acid derivative to install the two amino groups. Used as an oxidative hair-dye coupler with no natural source.

In plain English
