How we scored it

C20H12N2O2 312.3 Da: quinacridone skeleton built from petrochemical aniline and succinylsuccinate; 0 / 312.3 = 0.
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

Dialkyl succinylsuccinate is condensed with aniline, then ring-closed and oxidised to quinacridone. The route is fully petrochemical with no natural alternative.

In plain English

A synthetic violet-magenta organic pigment (quinacridone), listed here for hair colouring. It is made by chemical synthesis from petrochemical aromatic raw materials.
