NEED HELP! Quick question about VG nic base!!

[fourthrok]

I normally use PG nicotine base..usually 48mg. I've had really good success with it...I mix for 4mg. nicotine in my DIY juice. Anyway, awhile back I ordered a nicotine base from another vendor because they had a really good sale, and I'd bought hardware from that company before so I thought it'd be okay. While I requested PG (preferred) they sent 50% nicotine in a VG base. Rather than make a fuss about it (after all..I do use a little VG in my recipe, so what's the harm if some of it is in the nic base?) I put the stuff in a brown glass bottle and put it in the 'fridge where it's been since last August.

I want to try playing with it now...got my recipe set and ready to go. BUT..here I need your help. That VG nic base has been in the 'fridge awhile and is really cold. Can't shake it, obviously too thick. Can I just let it sit out a bit until closer to room temp, then shake, measure what I need and return the bottle to the 'fridge? Or is that a waste of time and I can go ahead and measure out while it's cold and not worry about shaking it? I'm just really used to a PG based nic base....and wonder how to treat the VG stuff. Will it hurt the nic quality for the temp to go from cold to room temp to cold again?

Any guidance here is much appreciated!!!!!!

I use 100% VG nic base. I take it out of the fridge, and let it sit till it warms up so I can shake it up and so it'll feed into my syringes. I haven't noticed any degradation in the nic content, but I don't really have a way to tell.

Thanks Slumberland! At least SOMEone answered. 62 views and you are the only one to respond! Anyway, I think I'll just take your word for it and let it warm up a bit then mix and put it back in the fridge. Should be okay, since it works for you!

you can also sit the jar in hot water to make it more fluid and easier to work with. Depending on the size of the jar, you can leave it out if you're going to do more DIY, or put it back in the fridge.
I use 100mg VG nic and don't have any problem with it.
I think all the viewers don't know the answer to your question since most people use nic juice in PG, and thay don't want to give you a wrong answer.
I wouldn't trust myself to measure nic when it is cold, viscous and extremely hard to measure.

One of those at least is me. I'm just learnin' To be honest, I was digging around for hints on how to handle VG myself - even when warmed and well shaken, I find it tricky to measure. Sticks to *everything*, and cannot get to feed into an 18 gauge syringe without a ton of patience.

You have the patience of Job to use an 18 gauge needle with VG. At least remove the plunger and pour the VG into the syringe! You need to get a 14 gauge needle (Green--http://www.onestopdiyshop.com/products/Blunt-Tip-Needle.html) and/or a graduated cylinder.
Also be sure to warm the VG before you use it. AQ little hot water will work wonders.

fourthrock, to try and make amends for piggy-backing on your thread, I did a bit of digging. Likely too late for now, but maybe useful for next time.

I had a difficult time finding much of anything on the effect of heat on nicotine, but I did find one journal article on the decay of nicotine in soaps (used as an insecticide). I don't have access, so I couldn't read the entire thing. You can read the first page here:

Deterioration of Soap-Nicotine Preparations

Abstract:
"Commercial soap-nicotine preparation decrease in nicotine content on storage. This loss is shown to be due to volatilization of nicotine and, in the case of soaps made from drying oils such as fish oil, to oxidation which results in a condensation product between the nicotine and the fatty acids. The work here reported shows that this decomposition can be prevented by packing the soaps so that they are completely protected from the air and that such products can be produced and marketed so as to retain their nicotine content for at least two years."

Obviously, a substance other than VG is being used to carry the nicotine, so I'm not sure how applicable it is. I thought it was interesting to note that the only two things that were mentioned as reducing nicotine content were volatilization (vaporising) and exposure to oxygen. In fact, as part of their testing process, they heated the soap to just under 100C, so I would assume that heating wouldn't cause the nicotine to break down in and of itself, or that would have messed up their results.

The other thing that I thought might affect measurement would be contraction of VG at lower temperatures. With a bit of googling I found this:
Coefficients of Cubical Expansion of Liquids

which (if I'm reading it correctly) says that glycerol (VG) will change volume by 0.05% per degree celsius of temperature change. Which all things considered should be within the usual margin of error for measuring. At least the way I measure

TL;DR sounds to me like storing in the fridge, heating and cooling, shouldn't affect anything, but keep tightly sealed.
Caveat: Even though we have google now, back in the day I did terrible in chemistry.

I don't know about patience, but determination, yes.

And apparently little forethought - never even occurred to me to use the syringe from the other side!

And thanks, myxomatosis, for the links. I will acquire some more appropriate devices
