Is Ammonium Phosphate natural?

Mostly. Phosphate is a natural mineral anion; ammonium is made from natural-gas-derived ammonia, treated as non-natural by this site's convention.

INCI nameAmmonium Phosphate
CAS7722-76-1
FormulaH9N2O4P · 132.06 Da
FunctionBuffering · Oral Care
FeedstockAmmonium Phosphate is made by neutralising phosphoric acid…

How we scored it

2 NH4+ (36.1 Da, Haber-Bosch natural-gas ammonia, this site's convention non-natural) + HPO4^2- (96.0 Da, mineral phosphate, natural) = 132.1 Da; 96.0/132.1 = 0.73
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

Ammonium Phosphate is made by neutralising phosphoric acid (mineral-derived) with ammonia produced from natural gas via the Haber-Bosch process. No bio-based ammonia route is commercially used.

In plain English

A buffering mineral salt combining naturally occurring phosphate with ammonia made from natural gas.
