Nicotine storage temperature?

[Rickajho]

I have been searching this issue in DIY and can't seem to find what I'm looking for.

I thought at one point there was a very lengthy quote from Wizard Labs regarding long term nic storage but I can't find it. On their web site it doesn't say much more about this than:

Nicotine solutions may be safely stored at room temperature. Optimal storage temperature is 34-41 degrees Fahrenheit. Nicotine solutions may be safely used for up to 18 months with proper storage.

But we're all freezing this stuff for long term storage, right?

My question is (was?) if stored in a freezer how low do you need to go? I will be storing in a small freezer dedicated to nic storage, so I can specifically optimize the temperature for this. At the same time I don't want to spend more on electricity than necessary keeping the freezer colder than needed.

Now reading the WL recommendation of between 34-41 degrees I'm wondering if I could have got by with a much less expensive refrigerator that can reach those temperatures instead.

As you have already stated this has been discussed numerous times but what I took from all the discussions about long term was VG as the carrier, dark glass bottles topped off with very little head-space (air) and stored in the freezer. Light and oxygen are your two enemies and the thickness of VG at low temps helps to keeps the nic molecules inactive with any oxygen that may be present.

Ok, that one led me to a couple things I had already found. But it also led me to this post by Roly which I couldn't find again because it's in general e-liquid, not DIY: http://www.e-cigarette-forum.com/fo...-refrigerating-e-liquid-ok-2.html#post6774084

That helped, thanks.

Yeah, that's one I already found but thanks.

In the last year-ish someone had posted a lengthy e-mail reply they received from Wizard Labs about this topic but I can't find it again. It was very long and technically detailed. But try searching for anything on ECF using key words "Wizard Labs" - lol. Good luck. I had to give it a rest after a couple hours of searching.

Thanks for the link AZPlumber! That was quite informative.

Yes great info but there is one statement that could be confusing for some folks. They state that nicotine oxidizes quicker in VG, this is only true when not stored in freezer. At room temp. the VG base will darken (oxidize) quicker than PG but when stored in the freezer the thicker VG will inhibit the nic's reaction with oxygen.
