Is CI 42080 natural?

Mostly not. The triphenylmethane dye core and its benzyl/ethylamino groups are synthetic/petrochemical; only sodium and sulfonate groups are mineral-origin.

How we scored it

C37H35N2NaO6S2: Na 23.0 + 2xSO3 160.1 = 183.1 Da mineral; remaining benzylethylamino-triphenylmethane-disulfonate core 507.7 Da petrochemical; 183.1/690.8 = 0.27
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

Made by synthetic organic chemistry from petrochemical aromatic amines and isolated as the sodium sulfonate salt.

In plain English

A synthetic triphenylmethane dye made from petrochemical aromatic building blocks. Used purely to add colour to cosmetic products.
