Petroleum Gases, Liquefied (Sweetened)

  • Aliphatic solvents
  • CAS 68476-86-8
  • IUPAC: Petroleum gases, liquefied, sweetened

Petroleum Gases, Liquefied (Sweetened) (CAS 68476-86-8) appears in 7 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).

Simple asphyxiant at very high concentrations (displaces oxygen). H280 (gas under pressure, may explode if heated). No specific organ toxicity or carcinogenicity. Primary hazard is fire — petroleum gases are extremely flammable. OSHA PEL: 500 ppm TWA.

Petroleum gases, liquefied (sweetened) is a refinery-derived mixture of C3–C4 hydrocarbons (propane, butane, isobutane) with hydrogen sulfide removed ("sweetened"). Used as an aerosol propellant in products where propane/butane alone would be labeled but the CAS 68476-86-8 blend notation is preferred.

The GHS classification is H280 (gas under pressure) for the compressed state. No inhalation toxicity H-codes beyond simple asphyxiation at extremely high concentrations — the main hazard is fire and explosion. Because it's used as an aerosol propellant, it's classified as VOC-exempt under US EPA and CARB regulations, which is why it doesn't count toward regulated VOC in aerosol products.

"Sweetened" (as opposed to "sour") means H2S has been removed by an amine treating process — this is standard for consumer-grade propellants to eliminate odor and corrosion concerns.
