How we scored it

Monoazo pigment from diazotized nitro-toluidine coupled with acetoacetanilide; no natural fragment or mineral counter-ion present → 0/340 = 0.00
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

Synthetic monoazo pigment manufactured by diazotization of a nitro-toluidine and azo coupling with acetoacetanilide, both derived from petrochemical benzene/toluene. No natural production route.

In plain English
