Fully synthetic anthraquinone dye; no natural fragment present; 0/340 = 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

Disperse Blue 377 is manufactured by chemical synthesis from anthraquinone (coal-tar/petrochemical aromatic) via amination steps. No commercially significant natural-origin route exists for this synthetic dye.

In plain English

A synthetic blue dye used to colour hair in dye products. It's made entirely from man-made chemical building blocks in a factory, not from plants or minerals.
