    Default So is Vaping glycerin dangerous?

    According to this article, glycerin produces acrolein when heated.
    Acrolein - Wikipedia, the free encyclopedia

    So is VG even more of a risk than PG?

    VG produces Acrolein when the VG is heated to 280 C ..... From what I have read the atomizer does not run at a high enough temperature to convert VG into acrolein

    I wonder if one of those overheating situations you get when there is too much juice floating around (dripping, etc) could get to that temp tho. I think Ill stick with PG, been doing well for me so far.

    So that's a yes then?

    If that's the case then are there any safe vapors?

    It does seem possible that the coil momentarily heats up to temperatures higher than 280 degrees C. Although I know liquid turns to steam at a much lower temperature it may actually need a very high temperature to 'instantly' turn a liquid to steam. Perhaps it is something to worry about...... Only a scientist could really give us an answer to that.

    I have just been looking up the Wikipidea article that this thread relates to and have only just realised that it is talking about glycer 'OL' turning into acrolyn at high temperatures .......we are using glycer 'INE'......and as far as I can tell it is completely different and certainly doesn't turn into acrolyn.

    Unfortunately I have also now studied the ingredients list on my bottle of TW liquid and it does say that it is made of 20% glycer 'OL' ...so I guess it is something to worry about.

    Yes I've seen that, and I believe the Evo got even hotter. Anyway, its more than 280c yes.

    Little chart I found

    Code:
    Color		Approximate	Temperature
    		F	C	K
    Faint Red	930	500	770
    Blood Red	1075	580	855
    Dark Cherry	1175	635	910
    Medium Cherry	1275	690	965
    Cherry		1375	745	1020
    Bright Cherry	1450	790 	1060

    glycerol and glycerine is the same thing with a different name.

    Glycerol - Wikipedia, Glycerol .....second line.
