Is Basic Violet 1 natural?

Mostly not. Synthetic triarylmethane hair dye supplied as a salt. Only the chloride counter-ion counts as natural origin under the site's mineral counter-ion convention; every carbon in the coloured cation is petrochemical.

How we scored it

Basic Violet 1 (methyl violet, modelled as the pentamethyl component) C24H28ClN3 394.0 Da: chloride counter-ion Cl 35.5 Da is mineral-derived (natural); the triarylmethane dye cation 358.5 Da is built entirely from petrochemical aromatic intermediates → 35.5/394.0 = 0.09.
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 amines and couplers assembled into the dye cation, isolated as its salt.

In plain English

A synthetic purple dye (commonly called methyl violet) used in hair colouring products. It's produced entirely from petrochemical raw materials.
