Is Hydroxylamine Sulfate natural?

Mostly. Sulfate counter-ion is mineral-derived; hydroxylamine itself is a manufactured nitrogen compound with no natural/fermentation feedstock, treated like urea's ammonia.

How we scored it

(NH3OH)2SO4, MW 164.14: SO4 (mineral, natural) = 96 Da; 2x hydroxylammonium (synthetic N-compound, treated like non-natural ammonia) = 68 Da → 96/164.14 = 0.59
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 by neutralising synthetic hydroxylamine (made from ammonia oxidation or nitrate reduction) with sulfuric acid. There is no natural-origin production route for hydroxylamine.

In plain English

An antioxidant salt combining synthetic hydroxylamine with sulfate. The sulfate portion is mineral-derived, but the hydroxylamine itself is a manufactured nitrogen compound, not sourced from plants.

CosIng definition: Bis(Hydroxylammonium) sulphate
