Is 2-Amino-4-Hydroxyethylaminoanisole Sulfate natural?

Mostly not. Sulfate counter-ion is mineral-derived; the anisole/aromatic-amine dye backbone is a wholly synthetic petrochemical structure.

How we scored it

H2SO4 (98.1 Da, mineral, natural) + methoxy-phenylenediamine free base (182.2 Da, petrochemical aromatic amine) = 280.3 Da; 98.1/280.3=0.35.
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

The aromatic amine free base is synthesised from petrochemical aniline and anisole derivatives, then salified with sulfuric acid. Only the sulfate portion counts as natural, mineral-derived mass.

In plain English

A hair-dye intermediate that reacts with other dye components to build colour inside the hair shaft. Its colour-forming backbone is fully synthetic; only the sulfate salt portion is mineral-derived.
