  • IUPAC: Dinitrogen

Nitrogen (CAS 7727-37-9) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).

Simple asphyxiant at very high concentrations. H280 (gas under pressure, may explode if heated). At ambient atmospheric levels, no inhalation hazard. No organ toxicity, carcinogenicity, sensitization, or reproductive concern. OSHA PEL 8h TWA not established (inert gas).

Nitrogen is used as an inert aerosol propellant in pressure-can products, particularly where hydrocarbon propellants (propane, butane, isobutane) would introduce flammability concerns. It is non-reactive and compatible with silicone grease, dielectric compounds, and electrical contact products.

The H280 classification (gas under pressure) is the only GHS hazard — the can may rupture if heated above 50°C (120°F), common to all pressurized aerosols. At room temperature and brief spray durations, nitrogen exposure is indistinguishable from ordinary breathing air (78% N2). No ozone-depleting potential, no VOC contribution.

They describe the ingredient itself; whether a hazard applies to a finished product depends on its concentration and how it's used.
