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

HC Red No. 10 is manufactured from petrochemical aniline via nitration, chlorination and alkylation with a propanediol side chain. No natural production route exists.
