How we scored it

Na2HPO4: sodium and phosphate are both mineral counter-ion fragments, natural origin by ISO convention = 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

Made by neutralising phosphoric acid, derived from mined phosphate rock, with a sodium mineral base. No petrochemical route is used.

In plain English

A mineral salt that keeps a formula's acidity steady and helps prevent packaging corrosion. Made from mined phosphate rock combined with sodium.
