How we scored it

Anthraquinone core synthesised from anthracene (coal-tar/petroleum aromatic); amino groups added synthetically. 0/238 natural mass = 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

Synthesised from anthracene, a petroleum/coal-tar aromatic hydrocarbon, via oxidation to anthraquinone then amination. There is no natural-origin production route.

In plain English

A synthetic dye used to colour hair or cosmetics. It's built entirely from petroleum-derived aromatic chemicals. No natural version exists.
