CarCareTruth tracks 1,1-Difluoroethane (HFC-152a) (CAS 75-37-6) as a car-care ingredient. It is classified as a VOC.
Simple asphyxiant at high concentrations. Inhaled deliberately (huffing) causes sudden cardiac arrest from sensitization of the myocardium — a real and documented risk for the propellant itself, not the product as intended-used. Aerosol use as designed presents minimal health risk.
1,1-Difluoroethane (HFC-152a) is a hydrofluorocarbon refrigerant and aerosol propellant. It replaced ozone-depleting CFC and HCFC propellants in consumer aerosols. Its main drawback is a non-trivial greenhouse gas warming potential, though it is short-lived in the atmosphere relative to other HFCs.
