The Autofrost web site (http://www.refrigerantsales.com/autofrost.html) has
the MSDS available. The stuff is only 4% isobutane. The other two
components are chloro-difluoroethane (CH3-CClF2 41%) and
chloro-difluoromethane (CHClF2 55%). Neither of these is a substance
which is "environmentally undesirable". We know that to be the case not
because they have been proven to be non-problematic but because the study
has never been done. IMO, that sux but who am I to gainsay the
authorities? A similar comment fits for R134. :-(
