How we scored it

Synthetic monoazo dye: 2-methoxyphenyl-diazonium coupled to naphthol, aromatic petrochemical fragments; no natural-origin mass.
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

CI 12150 is a synthetic monoazo pigment made by diazotizing petrochemical-derived methoxyaniline and coupling it to naphthol. Both aromatic building blocks originate from benzene/naphthalene petrochemical streams; there is no natural production route.

In plain English

A synthetic orange-red colorant used in cosmetics. Made entirely from petroleum-derived aromatic chemicals in a factory process - it has no natural source.
