How we scored it

K4P2O7, inorganic mineral salt; phosphate and potassium 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

Manufactured by neutralizing pyrophosphoric acid (from mineral phosphate rock) with potassium base. It is a fully inorganic mineral salt.

In plain English

A mineral salt made from phosphate and potassium. Used in toothpaste to buffer pH and bind trace metals, and in oral care to help control tartar.
