Is CI 74160 natural?

Mostly not. Only the chelated copper atom is mineral-derived; the entire phthalocyanine ring system is built from synthetic aromatic petrochemicals.

How we scored it

Copper phthalocyanine C32H16CuN8 (576.1 Da): Cu (63.55 Da, natural mineral) / total 576.1 = 0.11; aromatic macrocycle (512.6 Da) is fully synthetic.
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 74160 (Pigment Blue 15) is manufactured by reacting petrochemical phthalonitrile or phthalic anhydride derivatives with a copper salt under heat. Only the copper atom traces to a mineral feedstock.

In plain English

A bright blue synthetic pigment (copper phthalocyanine) used as a colorant. It's built from petroleum-derived aromatic chemicals locked around a copper atom; the copper is the only naturally-sourced part.

CosIng definition: CI 74160 is classed chemically as a phthalocyanine colour. It conforms to the formula:
