HFC-152a has potential as a propellant and its safety and formulation behavior are being investigated.

1,1,-difluoroethane (HFC-152a) has potential as a propellant and its safety and formulation behavior are being investigated. Recently, the University of Manchester carried out a comparative study to assess the carbon footprints of the following: pMDI with HFC-134a propellant, pMDI with HFC-152a propellant and blister-based dry powder inhaler (DPI).
