How we scored it

Trifluoromethyl-nitroaniline ethanol dye; fluorine chemistry is inherently synthetic. 0/250.17=0.00.
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

Manufactured from petrochemical trifluoromethylaniline via nitration and hydroxyethylamination. No natural route exists for organofluorine dyes.

In plain English

A synthetic dye used in hair coloring products. It contains a petrochemical trifluoromethyl-nitroaniline structure and is entirely synthetic.
