Is Hydroxyethylaminomethyl-p-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

Hydroxyethylaminomethyl-p-aminophenol dihydrochloride C9H16Cl2N2O2 255.1 Da: 2×HCl 72.9 Da is mineral-derived (natural); the aminophenol 182.2 Da is petrochemical → 72.9/255.1 = 0.29.
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 man-made aromatic chemicals in a factory. It has no plant or natural source.
