Vegetable Glycerin Material Safety Data Sheet.....

[Jim Bob]

If reading that concerned ME I would not read it


But seriously most of us (if not all) were smokers and we know the dangers there.

You won't find one for analogs unfortunately, which is why they can combine so many chemicals without getting in trouble. They test the product as a whole as I found out by reading a few huge studies recently. Interestingly enough there is up to 4.8% Glycerin in the tobacco they use to make analogs which helps it keep its moisture levels while they process it.

This is a good MSDS for glycerin though GLYCEROL MSDS

It says that toxic gases and vapors can be produced if brought to above 290*C which are dangerous, or if you just put a flame to it (smoking an analog). To be considered hazardous you would need 15mg per cubic meter of air space in a dust form, even then they don't even recommend a full face mask just a half mask for up to 10 times that level. Keep in mind that is a dry dust form and not even a diluted vapor.

This is the gas produced if you heat Glycerin to its boiling point or expose it to direct flame. Acrolein - Wikipedia, the free encyclopedia

Now the question is does a coil in an atomizer reach 290*C at any point to cause the chemical breakdown and gas formation.

Edit: Keep in mind that this gas created has a horrid smell, would know you were dealing with it instantly. I think the only way that we could produce an environment for this to happen was if the wicking material actually caught on fire and sustained a burn. Anyone with a temp sensor want to go blow up an atomizer for us?
