How we scored it

Estimated monoazo disulfonate dye: 2xSO3Na (206Da, natural) vs aromatic azo core (approx 274Da, petrochemical) approx 206/480 approx 0.43. Exact formula not supplied, structure estimated from dye class.
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

A synthetic monoazo dye manufactured from petrochemical aromatic amines via diazotization and coupling, then neutralized to its sodium sulfonate salt. No natural production route exists.

In plain English

A synthetic red azo dye used to color cosmetics. Manufactured from petrochemical aromatic compounds, with sodium and sulfonate groups contributing a mineral-derived portion of its mass.

CosIng definition: CI 14700 is classed chemically as a monoazo colour. It conforms to the formula:
