How we scored it

Inorganic mineral salt; Na+ and F- are both mineral-origin ions, no organic or petrochemical fragment present → 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 mineral fluorspar (calcium fluoride) or as a by-product of phosphate mineral processing, combined with sodium. An inorganic mineral salt throughout.

In plain English
