How we scored it

MW 576.6, O7S2/1Na: 1x SO3Na (natural, 103 Da) + 1x additional sulfonate/sulfonic group (natural, ~80 Da) ≈ 183/576.6 ≈ 0.32; dimethylaminophenyl/naphthalenol 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 dye built from petrochemical dimethylaniline and naphtholsulfonic acid intermediates, condensed and oxidised to the coloured cation, isolated as the sodium salt. No natural route exists.

In plain English

A synthetic green/blue triphenylmethane-type dye used to colour cosmetic products. Its coloured aromatic core comes from coal-tar-type synthesis; only the attached sodium sulfonate groups are mineral-derived.

CosIng definition: CI 44090 is classed chemically as a triphenylmethane colour. It conforms to the formula:
