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.
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.
Oops yes sorry I sure misread that ......so now I feel worried about glycerine .......oh dear.
i'd say....not really.
that is why we need some lab tests to see what is best for us.
According to the wiki, it only produces this substance when heated over 280c with the presence of "of a dehydrating agent such as KHSO4"
I would only be worried if some other flavoring or the alcohol acted in the same fashion.
"When a fat is heated strongly in the presence of a dehydrating agent such as KHSO4, the glycerol portion of the molecule is dehydrated to form the unsaturated aldehyde, acrolein (CH2=CH-CHO), which has the peculiar odor of burnt grease."
No burning grease odor in my e-cigs!

The size of the heating element determins how much heat it take to heat it to a certain degree. So, how big is the heating element used to make the chart. I don't think I could hold a e-cig in my hands if the heating element got that hot.
Has anyone had any issues using it?
I was thinking of using it to cut my Nic flavored EJ...

I have been doing some research on this and according to what I have found Glycerin would have to be heated for 4 to 4 and a half hours to produce any harmful substances
I've noticed that although VG generally produces less throat than PG, if the atomizer starts to get dry, the VG starts to have a really harsh taste to it that I don't like. This doesn't happen with PG. That's my two cents, though whether there's anything toxic about it or not I cannot say.
Edit: and it's also possible that the VG formula I'm using has some other substance causing the harshness when dry.

I find vg gives me breathing problems. If you are not having problems with PG, why switch? And is acroline worse than the 4000 toxins or the 65 carcinogens you get from smoking? For the sake of a few more whiffs of smoke you get from vg, and the dilute flavor you get from using it, is it worth it to you?
Did any of us stop and analyze the literally hundreds of toxic chemicals in analog cigarettes? I know I didn't, and I burned and inhaled those pieces of crap into my lungs for over 40 years.
