Is CI 60730 natural?

Mostly not. Only the sulfonate/sodium salt portion counts as natural-origin mineral mass; the anthraquinone chromophore and toluidine ring are synthetic.

How we scored it

SO3Na fragment (S32+O3(48)+Na23=103) counted natural per counter-ion convention; anthraquinone-amino-toluene core (~328) synthetic; total 431 → 103/431=0.24.
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 60730 is a synthetic sodium sulfonate anthraquinone dye. Its aromatic dye core is built from petrochemical anthraquinone and toluidine; only the sodium sulfonate salt group is natural-origin.

In plain English

A synthetic green dye from the anthraquinone family, made as a sodium salt. Manufactured mostly from petrochemical aromatic chemicals and used to colour cosmetic products.

CosIng definition: CI 60730 is classed chemically as an anthraquinone colour. It conforms to the formula:
