Is CI 40215 natural?

Mostly not. Stilbene and azobenzene rings are benzene-derived petrochemical fragments; sulfonate and sodium groups are mineral-origin natural fragments.

How we scored it

Supplied formula (C12H10N3NaO3S, 299 Da) is far smaller than the described stilbene-disulfonate/azobenzenesulfonate condensation dye - likely a data mismatch; trusting the description. Estimating from a typical multi-sulfonate azo/stilbene dye structure, sulfonate+Na fragments natural, aromatic rings petrochemical, giving roughly 0.25.
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 40215 is a synthetic stilbene/azo dye made by condensing petrochemical aromatic sulfonic-acid intermediates. No natural extraction route exists for this dye class.

In plain English

A synthetic stilbene dye used to add colour to cosmetic products.

CosIng definition: CI 40215 is classed chemically as a stilbene color. It is the condensation product of 4,4'-dinitro-2,2'-stilbenedisulfonic acid with 4-[(4-aminophenyl)azo]benzenesulfonic acid.
