How we scored it

Synthetic halogenated thioindigoid pigment built from benzothiophene chemistry; no natural fragment. 0/393 = 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 organic synthesis from petrochemical benzothiophene precursors, chlorinated and condensed to form the thioindigoid chromophore. No natural-origin production route exists.

In plain English

A synthetic red-violet pigment used to colour cosmetics. It is manufactured entirely through organic chemistry from petroleum-derived starting materials.
