Is Magnesium Hydrogen Phosphate natural? NOI 1.00

Q: Is Magnesium Hydrogen Phosphate natural?

Magnesium Hydrogen Phosphate has a Natural Origin Index (NOI) of 1.00 (scale 0–1) per ISO 16128. Magnesium and phosphate are mineral-derived and count as natural origin under ISO 16128. An NOI of 1.00 means 100% of its molecular mass is traceable to a natural, renewable source.

How we scored it

MgHPO4 is an inorganic salt: Mg and hydrogen phosphate are both mineral; 120.3 / 120.3 = 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 reacting magnesium oxide or hydroxide with phosphoric acid from phosphate rock. No organic or petrochemical fragment is present.

In plain English

A mineral salt of magnesium and phosphate used to keep powders from caking. It is made from magnesium minerals and phosphoric acid derived from phosphate rock.
