Is m-Aminophenol HCl natural?

Mostly not. Synthetic hair-dye aminophenol supplied as its salt. Only the mineral counter-ion counts as natural, as on the site's other hair-dye salts; every carbon is petrochemical.

How we scored it

m-Aminophenol hydrochloride C6H8ClNO 145.6 Da: 1×HCl 36.5 Da is mineral-derived (natural); the aminophenol 109.1 Da is petrochemical → 36.5/145.6 = 0.25.
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

Petrochemical aromatic amine or dye base isolated as its mineral-acid salt.

In plain English

A synthetic hair-dye ingredient made from petrochemical aromatic chemicals. It acts as a colour coupler, helping develop shade in permanent hair dyes.
