100% natural origin · ISO 16128

Is CI 77510 natural?

Yes. CosIng classes this as an inorganic colour; iron, ammonium and ferrocyanide are treated as mineral/inorganic ions under ISO 16128 convention.

How we scored it

Inorganic iron/ammonium/ferrocyanide complex; treated as simple mineral/inorganic ions with no organic carbon skeleton, matching other CI-numbered inorganic pigments → 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

Manufactured by reacting iron salts with a ferrocyanide and ammonium source to precipitate the inorganic pigment. No botanical or petrochemical organic feedstock is used.

In plain English

An inorganic blue-toned pigment made from iron, ammonium and a cyanide-containing compound. Manufactured chemically by combining iron salts with a ferrocyanide source.

CosIng definition: CI 77510 is classed chemically as an inorganic colour (see also INCI: Ferric Ammonium Ferrocyanide).
