How we scored it

Mineral copper sulfate (copper and sulfate both natural-origin ions) = 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 produced from natural copper ore and sulfuric acid mineral processing. No petrochemical route is used; both ions are mineral in origin.

In plain English

A mineral salt used in small amounts for skin conditioning. It's derived from copper ore, a naturally occurring mineral source.
