How we scored it
Copper-substituted chlorophyllin: botanical chlorophyll pigment (natural) plus copper replacing magnesium (natural mineral ion) → 1.00.
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
Made by extracting chlorophyll from green plant material and replacing the natural magnesium centre with copper. No petrochemical feedstock is used.
In plain English
A blue-green colorant made from chlorophyll, the green pigment in plants, with copper replacing its natural magnesium atom. Derived from green plant material.
CosIng definition: CI 75810 is a copper derivative of a botanically derived color obtained from green plants.
