I see,what do you feel is any benefit to having PG in it, would it reduce the production of acrolenin(spelling?) if the atty passed the point of overheating the VG it would be reduced since it is making PG vapor at the same time?
I might not understand more than about 20% of what you folks are talking about, but the 20% I do understand is quite interesting, I read every post
Do you have any recommendations for long term storage of flavorless eliquid? I've read of freezing it, refrigerating it(which for most home users is the same anyways, since it won't freeze at the temperatures we can provide) Not freezing it because freezing it will wreck it, adding dessicants to the storage area, not adding dessicants to the storage area etc.
I also read in one thread that citric acid was a good additive for long term storage, but in this thread it was recommended against.
Would PG or VG be better for unflavored liquid for long term storage?, I could go either way and mix down to 15mg at a 75/25 split, while keeping fresh base liquid around.
With the discussion of overheating VG, do you think that the thread about battery voltage would have any influence on the matter, with KR808 batteries providing even power and 510 batteries being pulsed?
EDIT: Wanted also to ask, with eliquid being basic instead of acidic, would more nicotine be absorbed through mucus membranes in mouth/nose, or in the lungs? I think that was answered, but I can't find it and wanted to verify. Trying to figure out if I can still get nicotine with a new vaping pattern(I was a suck a mouthful of smoke than inhale mixing with cool air smoker) I'm wondering, if I can get the same effect by sucking a mouthful of smoke and either blowing it out my nose or mouth, then taking a deep breath. I'm mimicking my smoking pattern but without getting much vapor in my lungs.
PG seems to have better germicidal properties than VG, as for acrolein, it's a potential with VG, but so far with vaping, the anecdotal evidence seems to put it down to more a theoretical problem than actual.
For flavorless liquids, cool and dark is probably enough. A touch of citric acid might help, it might not. My only objection to citric acid is from it's breakdown at high temperature, again more a theoretical than actually observed problem.
VG or PG as a storage base? I dunno, unless someone else knows a compelling reason for one or the other, I'd call it a pick'em.
As far as absorption, that's pretty much a current hot topic, and there are a lot of principles that can be applied to make educated guesses about what's going on... but I'm hesitant anymore to try to over-apply these principles since it's a fairly complex system. I do firmly believe that since nicotine users become unconsciously "expert" at regulating their nicotine uptake (self-titration), that aware of it or not, we figure out what works for us.
