How we scored it

This name and CI 74260 are two listings of the same colorant, so it carries that entry's value: 0.06.
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

Copper phthalocyanine made from petrochemical phthalic anhydride and urea with copper, then chlorinated.

In plain English

A green pigment used to colour hair products. It is a copper-containing ring molecule with chlorine atoms attached, made industrially from petrochemical building blocks, copper salts and chlorine from salt.
