Is Zinc Carbonate natural? NOI 1.00

Q: Is Zinc Carbonate natural?

Zinc Carbonate has a Natural Origin Index (NOI) of 1.00 (scale 0–1) per ISO 16128. Zinc and carbonate are both explicitly natural-origin mineral fragments under ISO 16128. An NOI of 1.00 means 100% of its molecular mass is traceable to a natural, renewable source.

How we scored it

Mineral zinc carbonate; Zn metal ion and carbonate are both natural-origin = 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

Mined or precipitated from mineral zinc sources as zinc carbonate. A straightforward mineral-origin ingredient with no petrochemical route.

In plain English

A mineral zinc compound used to opacify (whiten) formulas. Comes from mined or manufactured mineral zinc sources.
