A while back there was discussion about using Envirosafe ES12 as a subistitute for R12. Discussion was fairly heated over if Envirosafe ES12 was an approved refregrent. That thead is here: http://corvetteactioncenter.com/forums/showthread.php?s=&threadid=14042
To get to the facts I sent an e-mail to the EPA asking. Just received the response. Here is what it said:
Under U.S. law, only those substitutes approved by EPA may legally be used to replace ODSs {ozone-depleting
substances} , such as CFC-12 ("freon") in automobiles and other applications that farmers have used ODSs in the past.
Envirosafe ES-12 has never been submitted to the EPA for review, and therefore it is illegal to use this chemical as a substitute for any ODS, such as CFC-12 in automobiles. For a list of those substitutes that have been approved, please refer to http://www.epa.gov/ozone/snap/lists/index.html. Although I do not have specific information on ES-12, others have indicated that it is a mixture of flammable hydrocarbon substances. As you may be aware, the EPA has specifically found all flammable refrigerants unacceptable as substitutes for CFC-12 in automobiles.
