How we scored it

C8H12N2O (petrochemical diaminophenoxyethanol) 168.19 Da + H2SO4 (natural sulfate) 98.08 Da → 98.08/266.27 = 0.37.
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

Synthesized from petrochemical aminophenol/nitrophenol intermediates reacted with ethylene oxide, then salted with mineral sulfuric acid for permanent hair-dye use. No alternative route exists.

In plain English

A synthetic aromatic dye intermediate, sold as its sulfate salt, used in permanent hair-colour formulas to help build colour shades.
