How we scored it

Calcium + sulfate, both mineral-derived, 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

Calcium sulfate is derived from natural gypsum rock, or recovered as a byproduct of mineral processing. Both the calcium and sulfate portions are mineral-derived.
