How we scored it
Mineral salt K2HPO4; potassium and phosphate are both natural-origin, so 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
Produced from phosphate rock and potassium salts, both mined mineral feedstocks. It is a straightforward inorganic salt with no organic component.
In plain English
A mineral salt used to buffer a formula's acidity and help prevent corrosion. It's made from naturally mined phosphate and potassium minerals.
Structure
dipotassium;hydrogen phosphate
