Is CI 44045 natural?

Mostly not. Synthetic hair-dye triarylmethane dye cation 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

CI 44045 (the colorant listing of Basic Blue 26) C33H32ClN3 506.1 Da: 1×chloride 35.5 Da is mineral-derived (natural); the triarylmethane dye cation 470.6 Da is petrochemical → 35.5/506.1 = 0.07.
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 blue dye used to colour hair, built entirely from petrochemical aromatic amine compounds.
