Think this stuff will never go away!!!!! Nothing new here...been here....been tested.....

This info from msds:
Material: CAS Number Typical Wt. %
Chlorodifluoromethane (HCFC-22) 75-45-6 50% ................(not good in a R12 system....causes all sorts of problems...esp with rubber lined hoses)
2-Chloro-1,1,1,2-tetrafluoroethane (HCFC-124) 2837-89-0 39%
1-Chloro-1,1-difluoroethane (HCFC-142b) 75-68-3 9.5%
Isobutane (HC-600a) 75-28-5 1.5% .......(carrier for mineral lube)
*Regulated as a Toxic Chemical under Section 313 of Title III of the Superfund Amendments and Reauthorization

When retro fitting.....if this is the desired path....simply use 134a...works good.....can be recycled ....used more than one...the stuff above...use only once....has to be charged as a liquid....not Diy'er friendly......simply question....WHY???
Oh, yes..it is not a drop in replacement for R12....some advertisements lead one to think this can be added in with existing R12....ahhh...so....not so....only refrigerant that can top off an r12 system is r12.....all others have a specific retro fitting procedure and require the complete removal of r12 and the use of dedicated service port fittings....

To mention, unique fittings for the particular blended refrigerant. Not R134a or R12 fittings. Also, an AC shop probably won't even hook up their equipment to your car if it doesn't have an recyclable refrigerant such as R134a or R12.

I'm sure the HCFC refrigerant would probably work fine... but those refrigerants were only transitional to help get away from using R12, and are scheduled to be banned if not already.

In addition to what iceman said this is from the EPA website


Misleading Use of "Drop-in" to Describe Refrigerants

Many companies use the term "drop-in" to mean that a substitute refrigerant will perform identically to CFC-12, that no modifications need to be made to the system, and that the alternative can be used alone or mixed with CFC-12. However, EPA believes the term confuses and obscures several important regulatory and technical points. First, charging one refrigerant into a system before extracting the old refrigerant is a violation of the SNAP use conditions and is, therefore, illegal. Second, certain components may be required by law, such as hoses and compressor shutoff switches. If these components are not present, they must be installed. See the section below on use conditions for more information on these points. Third, it is impossible to test a refrigerant in the thousands of air conditioning systems in existence to demonstrate identical performance. In addition, system performance is strongly affected by outside temperature, humidity, driving conditions, etc., and it is impossible to ensure equal performance under all of these conditions. Finally, it is very difficult to demonstrate that system components will last as long as they would have if CFC-12 were used. For all of these reasons, EPA does not use the term "drop-in" to describe any alternative refrigerant.

It's also rather expensive and likely to go higher in the future since the R-142b and I think also R-124 components are under production ban status like R-12.
