How we scored it
Elemental N2 gas separated from air by cryogenic distillation; no synthesis, all 28.01 Da is natural-origin.
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 by cryogenic fractional distillation of ordinary air. It is a purely physical separation process with no chemical synthesis involved.
In plain English
An inert gas used to push product out of pressurised containers, keeping the formula from contacting oxygen. It's simply separated from ordinary air, not chemically made.
Structure
molecular nitrogen
