HC-12a is a mixture of hydrocarbons , specifically propane (R-290) and isobutane (R-600a), and is therefore considered nearly non-ozone-depleting.

New cars produced in the early 1990s contained the new refrigerant in their air conditioning systems. Owners of older cars with R-12 systems would either have to invest in an R-12 to R-134a conversion system, buy a new car, or find a qualified technician to recharge their older R-12 system. R-134a has been used in cars for almost 30 years.
