Is Tetrasodium Pyrophosphate natural?

Yes. Sodium and phosphate are explicitly mineral-origin ions; pyrophosphate is two phosphates condensed with water loss.

How we scored it

Fully inorganic condensed-phosphate salt: 4 Na+ and pyrophosphate (P2O7^4-), both mineral-origin → 1.00.
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 dehydrating sodium phosphate, itself sourced from mined phosphate rock, into the condensed pyrophosphate salt. No organic or petrochemical feedstock is used.

In plain English

A mineral salt of sodium and phosphate used in toothpaste to help prevent tartar buildup and to bind trace metals in formulas. Made from mined phosphate rock.

CosIng definition: Tetrasodium Pyrophosphate is the inorganic salt that conforms to the formula
