Excerpt from DOW chemical report, on PG

[SteamyTheBear]

"Physical Hazard Information

PG has a low vapor pressure and is not expected to volatilize. PG is stable unless elevated to high temperatures, at which point it can decompose. During a fire, smoke may contain the original material in addition to unidentified toxic and/or irritating compounds. Hazardous combustion products may include and are not limited to: aldehydes and carbon monoxide."

Sorry I can't link the original, my post count is not high enough.

Still, obviously better than cigarettes, but this explains some of my adverse reactions, possibly. That, or I'm just allergic lol

Guessing you're just allergic ... I don't believe the temperatures reached in a pv/eni/ecig are sufficient to trigger decomposition, and I know they are insufficient to produce fire.

If you are having trouble with pg try vg. I've been using it for over a year. Can't use pg at all, but no problems with vg.

Steamy you may just be allergic, or not maybe not getting enough water in your system while vaping with the PG. I haven't seen a thread on this, what are your symptoms?

As to the report, I really don't think the heating element on e-cigarettes are hot enough to cause any kind of decomposition. Posts made by several users say that they measured the temperature of the element in their own equipment at high 90s to low 100s Fahrenheit. Dow is talking fire which, depending on source, can be upwards of 1000 degrees Fahrenheit. A candle flame burns at 1000. As the report stated, the vaporization point of PG is low, and since it is commonly used in fog machines, both commercial and home units, I would say it's safe enough at the temps we use.

"low vapor pressure" refers to the gas pressure of the liquid that would cause PG to vaporize into the air or evaporate. Open a bucket of PG in a room and not much evaporates, well not as much as an open bucket of gasoline. When vapor pressure increases, like due to heat, stuff boils. Burning of most hydrocarbon materials produces compounds of carbon and oxygen.

Ok, thanks guys! I'm currently vaping some AC from tastyvapor, and they don't do 100% vg
