Propellent Gas
Also known as: propellant gas, propellent, propellant
Generic 'propellent gas' refers to inert food-grade gases such as nitrogen (E941), nitrous oxide (E942), and carbon dioxide (E290), all GRAS for their intended use. The non-specific label limits ingredient transparency, but at the doses used in food packaging the gases are inhaled briefly with the food and pose minimal health concern.
What it is
A functional class of gases (commonly nitrogen, nitrous oxide, carbon dioxide) used to expel food from pressurized containers.
Propels food (e.g., whipped cream) from aerosol containers; may also aerate.
Why it's flagged
- non-specific labeling
What regulators actually say
"Nitrogen is a colorless, odorless, tasteless, gaseous element that constitutes about 78 percent of the atmosphere by volume."
"Nitrous oxide is a colorless, sweet-tasting, slightly water-soluble gas... used as a propellant."
Regulatory status

Specific propellants (N2, N2O, CO2) are GRAS under 21 CFR 184
European Union — EFSA
Specific E numbers (E290, E941, E942) approved; functional class plus specific name required
