How we scored it

Diamine C6H7N3O2 153.14 Da (petrochemical nitroaniline isomer, n=0) + H2SO4 98.08 Da (mineral sulfate, n=1); 98.08/251.22 = 0.39
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 from benzene-derived nitroaniline intermediates and combined with sulfuric acid to form the sulfate salt; used as an oxidative hair-dye coupler. No natural-extraction route exists.

In plain English

A synthetic hair-dye ingredient that helps develop colour during permanent hair colouring. It is manufactured from petroleum-derived chemicals and does not occur naturally.
