How we scored it

Inorganic mineral salt (KH2PO4); potassium and phosphate ions both 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

Manufactured from mined phosphate rock reacted with a potassium source. Used as a pH buffer in cosmetic formulas.

In plain English

A mineral salt used to buffer pH in cosmetic formulas. It's produced from mined phosphate rock combined with potassium.
