Dammit! You're right. It is polyethylene glycol. I'm glad I didn't vape it! I guess I'll take it back. Bummer.
I'm not sure how that would work with the powdered PEG, but I HAVE seen polyethylene glycol eJuice!
A few companies let you choose between a VG, PG or PEG mix in their juices.
PEG is sold by brand name as "Miralax"
PEG works in the intestines by bringing more liquid to your intestines via osmosis. I imagine it could do the same in your lungs, so I'll stick to VG, although I'm not sure to what degree, but it is used! I don't know the percentages, although I'm sure it's floating around here or somewhere on the web. It is water soluble, so I'd used sterile, deionized water to dilute it if you try it...
I would use caution though, as it may bring fluid to the lungs, yet PG & VG may do the same, and if done to a VERY small degree, it might make a good vapor in dry summers & winters?
Heck, with eucalyptus and/or menthol it might even be great for coughs!
Ever used Vapor Rub? Hmmm... This might not be such a bad think, but I would certainly do some homework on this one!
Check out rxlist DOT com for more info. You can google their site and add the word "Miralax" to your search, and it should come right up!
Google PEG eJuice and you'll get over 8,000 hits, so yep! it's being used!
Happy Vaping!
