From Wikipedia "In early 2008, true MAPP gas production ended in North America when production was discontinued at the only remaining plant in North America that still manufactured it. However, many current products labeled "MAPP" are, in fact, MAPP substitutes. These versions are composed almost entirely of propylene with minuscule impurities of propane (<0.5%).[1]"

It often yellows or browns when I hit it with a hot torch. I can bubble it if I have the mix too rich. I'll always lean out the mix to try to reduce this issue and most of the time it's fine. But you have to be careful about your mix.
