How we scored it

Entire C18H10Cl2O2S2 chlorinated bis-benzothiophenone core is synthetic aromatic chemistry; no natural fragment or mineral counter-ion present → 0/393 = 0.00
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

Synthetic vat dye manufactured by condensation of chlorinated methylbenzothiophenone intermediates derived from petrochemical aromatics. No natural production route exists.

In plain English

A synthetic chlorinated dye from the thioindigo family, used to colour cosmetic products. It's built entirely from manufactured chemical intermediates.
