can you freeze e-liquid?

[zoomie61]

Kinda curious, can you preserve e-liquid in the freezer? Just wondering in case we have to stock up... (sorry I posted in the wrong place before)

stock up as in if the FDA says something

I don't see why not, I don't know if nicotine or the flavorings are that perishable to have to though

Any compound can be turned into a solid (freezing); however, the standard temperature of a freezer is not cold enough to freeze e-juice; however, it will thicken in the freezer.

good point mwahle1...I never thought about the freezing point> Is it the PG? I was only thinking of the H2O

 

[mwahle1]

I am almost positive it is the PG (without actually looking it up).

isn't pg used in the 'pet-safe' antifreeze? if so, i'd figure it was the pg, too. i'd be interested to know if the liquid suffered any other ill effects from being at that low of a temp tho... if not, i might relocate my juice stash to the back porch freezer. (yes, i live in the boonies and have a freezer on my back porch. )

Yes, propylene glycol is used as antifreeze coolant for cars. It is gradually replacing ethylene glycol (the green stuff) because it is less toxic. By itself, it freezes at -59 C, or -74 F.

There are some pretty long threads on storage on these forums. The general idea seems to be that while excessive heat is bad, normal room temperatures seem fine. The bigger concerns are oxidation and contamination.
