How we scored it

MW 808.9, O10S3/2Na: ~2x SO3Na (natural, ~206 Da) + 1 additional SO3(H) group (natural, ~80 Da) ≈ 286/808.9 ≈ 0.35; triphenylmethane core petrochemical
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

A synthetic triphenylmethane dye made by condensing petrochemical aromatic amines with benzaldehyde-sulfonic acid derivatives, then oxidising. No natural-extraction route exists.

In plain English

A synthetic blue-green triphenylmethane dye used to colour cosmetic products. Its aromatic core is built from coal-tar-type chemicals; only the sodium sulfonate groups attached to it are mineral-derived.

CosIng definition: CI 42053 is classed chemically as a triphenylmethane colour. It conforms to the formula:
