Freezing?

[w1ngz]

I can't seem to find a thread on this.

Do VP/PG based liquids freeze? Winter is coming and I'm wondering what might happen to any liquid I order that could end up sitting in my mailbox until I get home from work.

Check out post # 17 in this thread http://www.e-cigarette-forum.com/forum/general-e-liquid-discussion/118956-can-you-freeze-juice.html

Thanks! Good info, post 23 actually went right to the point.

My juice stock pile has been in freezer over one year with no problems.

I dare you to try freezing it! (liquid nitrogen would probably do it - lol ). It does get thicker tho.

in a word..."NO"....separation of chemicals during freezing..unfreezing causes a collection of water/condensation as well, which is not good for the atomizer....

e-juice does not freeze at normal freezer temps - and thus I would not worry about leaving is mailbox - but it is a good idea if you are storing unflavored nic-juice for a long time to do so in a freezer - see post #9 in the thread below

I'd just like to redirect the topic of this thread a little bit... like most any forums, I guess there are people who jump to conclusions based solely on the subject, and not reading the first post.

My question was not about whether I should choose to freeze my juice.

My question is whether or not it would degrade the liquid when an order is left in the mailbox all day, beyond my control, in freezing temperatures. That can sometimes mean -20C/0F, or colder, which is a lot lower than it is in a freezer.

It seems it's not bad for it, so I won't worry it. Thanks all!

It is stated in the thread what freezing temps are for vg, pg, and nic....

I think we all read it (I did). The point is, you can't freeze pure PG even at -38C. Probably no effect, except it gets a little thicker. Warm it, shake.

This, of course, could vary depending on the recipe. rockyroad is correct, check the thread for the freezing points.
NM, I checked a wiki. Here's % of PG to water and freezing points up to 60%PG/40% water.

Percent Propylene Glycol (wt. %) Freezing Point (°F) Freezing Point (°C)
0 32 0
10 26 -3
20 20 -7
30 10 -12
36 0 -18
40 -5 -20
43 -10 -23
48 -20 -29
52 -30 -34
55 -40 -40
58 -50 -46
60 -60 -51

The lowest temperature ever recorded in Montreal was −37.8 °C (−36 °F) on January 15, 1957. So now you can decide on what mixture you wish to order. Looks like you're safe even with some added water. Note VG has a higher freezing point but I think that it is still very cold.

Now, I dare you to try and freeze your juice! lol.

Have fun!

Good to know.
I looked up the same information on VG and it's minimum temp is specifically at a 70% mixed with 30% water where it freezes at about -36. From there anything higher, it actually shoots back up and freezes well ABOVE the freezing point of water when it is 100% glycerol. Interesting! It would seem that a pure VG e-juice with a low nic content could well freeze solid, depending on the recipe and outside temperature. Higher nic content will help, but I'm not near well versed enough to calculate what the freezing point of a 18mg VG nic solution would freeze at compared to a 12mg or 24mg.

Now, I dare you to try and freeze your juice! lol.

I may well take that dare when January/February comes and it hits -30 something for 2 weeks.

LOL.. You're On! Bet ya a nickel! But ... you have to have 50% PG in it too..... Also, I hope you don't leave juice sitting in the mailbox over 24 hrs. Good luck!!!!

Well that's hardly fair. Do you have any idea how much farther north I'd have to move to win that?? lol

If all goes well, I hope to have figured out my preferred PG/VG ratio and favourite flavours, and be mixing my own by then so it shouldn't even be an issue

Good luck with the diy wingz and don't forget the crystals...
