How we scored it

1,4-bis(4-methylanilino)anthraquinone, C28H22N2O2: anthraquinone (from anthracene, coal-tar) + 2x p-toluidine (petrochemical aniline derivative), no ionic/mineral fragment → 0/418.5 = 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 condensing anthraquinone (from petroleum/coal-tar anthracene) with p-toluidine (a petrochemical aniline derivative). No natural-origin route exists for this synthetic dye.

In plain English

A synthetic green dye used to colour cosmetic products. It is made entirely from coal-tar-type aromatic chemicals (anthraquinone and toluidine) with no mineral or plant content.

CosIng definition: CI 61565 is classed chemically as an anthraquinone colour. It conforms to the formula:
