How we scored it

NaPO3 repeat unit; sodium and phosphate are both mineral, 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

Sodium metaphosphate is manufactured by heat-condensing mineral phosphate derivatives with sodium carbonate or hydroxide. It is a purely mineral, inorganic salt.

In plain English

Sodium metaphosphate is a mineral salt used to buffer pH, bind trace metals and help clean teeth. It's made from mined phosphate minerals.
