How we scored it

Synthetic monoazo dye: 4-ethoxyphenyl-diazonium coupled to naphthol, both aromatic fragments from benzene/naphthalene petrochemicals; no natural fragment present.
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 12010 is a synthetic monoazo pigment made by diazotizing petrochemical-derived ethoxyaniline and coupling it to naphthol, both aromatic intermediates from benzene/naphthalene. There is no natural-origin production route for this dye class.

In plain English

A synthetic orange-red pigment used to colour cosmetics like lipstick. It is built in a factory from petroleum-derived chemical building blocks - there is no natural source.

CosIng definition: CI 12010 is classed chemically as a monoazo color. It conforms to the formula:
