How we scored it

ZnSO4: Zn2+ and sulfate both mineral-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

Produced from mined zinc ores or as a by-product of zinc refining, combined with sulfate. This is the standard commercial source.

In plain English

A mineral salt used in oral care and antimicrobial products, and as an astringent. Derived from mined zinc ore and sulfate minerals rather than synthesised from petrochemicals.
