Is Diammonium EDTA natural?

No. The EDTA backbone is built from petrochemical formaldehyde, cyanide and ethylenediamine; the ammonium counter-ions are natural-gas ammonia by this site's convention.

How we scored it

EDTA acid core C10H16N2O8 292.2 Da (synthetic, formaldehyde/cyanide/ethylenediamine route) + 2 NH3 34.1 Da (natural-gas ammonia) = 326.30 Da; both fragments non-natural. 0.0.
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

EDTA is synthesised from ethylenediamine, formaldehyde and sodium cyanide, then partially neutralised with ammonia. No natural-feedstock route exists for any fragment.

In plain English

Diammonium EDTA is a chelating ingredient that binds trace metals to protect a formula from degradation. It's built entirely from synthetic industrial chemicals.
