Low Resistance, High Voltage and Acrolein - a vaper's experience

[Drozd]

The REAL question is, who told the Brits they could invent this celcius "Thing" and mess w/ all our rational measurements. LMAO

*as he hits his sauce*

lol.....don't you remember.... we were supposed to have changed over to metric ourselves a long time ago now...

Hhmm. Found this while snooping the web(from Wiki):

Historical cases of contamination with diethylene glycol
On May 4, 2007, the US Food and Drug Administration advised all US makers of medicines to test all batches of glycerine for the toxic diethylene glycol.[17] This follows an occurrence of 100 fatal poisonings in Panama resulting from a Chinese factory deliberately falsifying records in order to export the cheaper diethylene glycol as the more expensive glycerol.[18] Glycerine and diethylene glycol are similar in appearance, smell, and taste. The US Federal Food, Drug, and Cosmetic Act was passed following the 1937 "Elixir Sulfanilamide" incident of poisoning caused by diethylene glycol contamination of medicine.

Could be a usefull tool in debating the anti e-cig sentimate of the FDA. It seems that the chinese made glycerin was the problem, not the juice it's self. Facinating.

Imma make a post w/ my metric inept brain in the general e-cig forum. This is usefull info

This makes me wonder about the pressure's relevance to the vaporization temperature of VG. Since you're drawing on the atomizer, the temperature required to boil the VG into vapor is much lower (see vapor pressure). I'm no chemist, but I don't think this affects the decomposition temperature of VG, so it should be vaporizing before it has the chance to decompose as long as you're drawing on it, correct?

Correct! Vaporization SHOULD occur at a much lower temp than decompsition. Good point!

It's also worth pointing out that while no acrolein has ever been found in PV vapour it definitely is in cigarette smoke. It's interesting how terrified people get of these substances once they stop smoking. I bet you'd never even heard of it before, let alone knew you were inhaling it 20 times a day.

So do we have an explanation for the observations in the OP? His 'flushing' symptoms are only present when using LR attys. Maybe his conclusions about why that is are not accurate... but leaves me wondering, why is that?

This is a complex subject and I think we are years away from finding any answers to the odd reactions some people have that seem to be associated with vaping in some way. The trouble is that these cases are so rare.

As regards VG and acrolein, the largest manufacturer of 100% VG eliquids in the West, Intellicig, had their Ecopure brand tested at 300 degrees C for acrolein generation and none was found. If they are happy with the situation then we have to be; they would not allow this type of contamination since it would be game over for them. They issue no warnings about high-power atomizer use, which they would have to do if their product could not be used in all e-cigarette equipment - which by definition includes LR, 5 volt and 6 volt equipment.

Correct, and as I have pointed out before, although I do not trust the FDA, I do trust that they will use any tactic available to them to stop us from vaping. Since they have made no mention of Acrolein(which again, IS present in cigarette smoke), I have to believe that they have failed to produce any w/ a PV.
