Is Chlorophyllin-Copper Complex natural?

Yes. Entire ring carbon skeleton derives from plant chlorophyll; the copper and sodium introduced are mineral-origin per ISO convention.

How we scored it

Chlorophyll ring system (natural pigment) + Cu replacing Mg (mineral, natural) + Na carboxylate from ester hydrolysis (natural) → 1.0.
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

Made from plant chlorophyll (e.g. alfalfa or nettle) by alkaline hydrolysis of its methyl/phytyl esters and exchange of magnesium for copper. Neither step introduces petrochemical carbon.

In plain English

A green-blue colorant made from plant chlorophyll by swapping its natural magnesium for copper. Used to tint products and to help fight odour or oxidation.

CosIng definition: Chlorophyllin-Copper Complex is obtained from chlorophyll by replacing the methyl and phytyl ester groups with alkali and replacing the magnesium with copper. To identify the colorant meeting the requirements for labeling purposes in the US, the INCI Name Chlorophyllin-Copper Complex must be used. To identify the colorant allowed for use in the European Union (EU), the INCI Name CI 75810 must be used.
