  • Other solvents
  • CAS 68476-85-7

Hydrocarbon Propellant (Propane/Butane/Isobutane Blend) (CAS 68476-85-7) appears in 3 of the 1,812 car-care products CarCareTruth tracks (as of June 2026). It is classified as a VOC.

Extremely flammable (H222/H229). Simple asphyxiant at high concentrations. Huffing causes sudden cardiac arrest — a real risk for the propellant component itself when misused, not the product as designed.

Hydrocarbon propellant is a generic designation for blends of propane, butane, and isobutane used as the pressurizing gas in aerosol cans. It is the most common propellant class in consumer aerosols and contributes both to flammability and VOC content.
