Details of a number of refrigerants are provided below for you information.

R11 (OPD=1.0 / GWP=4000)
A single chlorofluorocarbon (CFC) compound. A high chlorine content ensures high ODP & GWP. Non toxic. Exhibits no glide or fractionation. Can be charged in gas form. OUTLAWED
 
R22 (OPD=0.05 / GWP=1700)
A single hydrochlorofluorocarbon (HCFC) compound. A low chlorine content ensures modest ODP & GWP. Non toxic. Exhibits no glide or fractionation. Can be charged in gas form
 
R134a (OPD=0.0 / GWP=1300)
A single hydrofluorocarbon (HFC) compound. A zero chlorine content ensures no ODP & modest GWP. Non toxic. Exhibits no glide or fractionation. Can be charged in gas form
 
R404a (OPD=0.0 / GWP=3750)
A ternary blend of hydrofluorocarbon (HFC) compounds (R143a/R134a/R125). A zero chlorine content ensures no ODP but high GWP. Non toxic. Exhibits modest glide and fractionation. Can be charged in gas form, but liquid form is recommended
 
R407c (OPD=0.0 / GWP=1610)
A ternary blend of hydrofluorocarbon (HFC) compounds (R32/R134a/R125). A zero chlorine content ensures no ODP but modest GWP. Non toxic. Exhibits high glide and significant fractionation. Must be charged in liquid form, leakage is best treated with recovery and full recharge
 
R410a (OPD=0.0 / GWP=1890)
A binary blend of hydrofluorocarbon (HFC) compounds (R32/R125).
A zero chlorine content ensures no ODP but modest GWP. Non toxic. Exhibits minimal glide and fractionation. Can be charged in gas form, but liquid form is recommended
 
Notes:-
 
'Fractionation' occurs as each seperate compound in a blend 'boils' at a different temperature, thus leakage can result in the loss of only one compound within the blend.
'ODP' is Ozone Depletion Potential. The ODP factor applies to refrigerant gas and it's potential to damage the ozone layer. The ODP is always quoted relative to that of R11 which is taken to have a factor of 1.0
'GWP' is Global Warming Potential. This figures takes into account more overall installation performance. As well as ODP the factor allows for plant energy consumption resulting in 'relocated' pollution.
