VGF Base vs. PG Base

[junkman]

I just put 500ml of VG base eliquid into 60ml bottles and into the deep freeze.

I ordered the VG base because I understood that VG will freeze or come close to freezing while PG won't freeze - and therefore VG should be more stable.

Is that a correct assumption?

However, after dealing with the VG base, I feel like PG would probably be much easier to work with as the VG is so thick that pouring it is slow and tedious, and leaves behind liquid in containers, etc.

What is the wisdom of the ecf on this?

Should I just use PG base going forward? Will frozen VG base keep longer than PG in the deep freeze?

 

[ninfreak]

neither will freeze at the temps our freezers go to....and both should last many years "frozen".

OK - I thought I read that VG would freeze?

If not then I guess PG is a better solution, at least for me. Handling that VG is a pain.

nope doesn't freeze just turns to sludge thicker than molasses

OK, then I will order PG base from now on.

Neither will freeze in our home freezers.

The main consideration for which one you purchase/use should be based upon your PG/VG ratio. If your ratio is more PG than VG, i.e. 75PG/25VG, then get the PG based nic.

I freeze my 25 mg VG base in glass bottles. I figure it can't hurt and may keep a little better than not. At any rate, VG base is not 100% Glycerin USP. It's been mixed with nicotine exposing it oxygen and moisture in the process. I expose my base to further oxygen and moisture when I cut and mix it down from the 100 mg I buy. I don't keep much more base on hand than I can use during the next 18 months.

My Glycerin USP from CVS has a batch number and an expiration date of 9/2017. Oh yes, it will store that long in the dark at cool room temperature so long as the seal on the bottle is not broken.

The 100 mg nicotine base I get from Xtreme vaping is made with Glycerin USP but has an expiration date of 12-18 months after I buy it, as it should.

Yeah, I usually buy 80PG/20VG.

I figured I could dilute the 100mg VG 5x to 20mg with PG, and I assume I could dilute 100mg PG to the same level, so not sure why that would make a difference?

I just split my 100mg base into 60ml bottles and froze them at full 100mg strength. I figure that if they are good for 12-18mos outside a freezer, they have to last longer at freezer temps. Plus, expiration dates tend to be very very conservative. I figure I could eat 2 year old cheerios if I was hungry enough.

LOL. I tried a single serving box of Trix that was on my boat for two years once. Only one nasty mouthful was enough.

Maybe if you were having Trix withdrawl, you would have finished it?

 

[yzer]

Sometimes I'll eat just about anything I can find on the boat. I keep a good store of canned food on hand for that reason. But, those Trix were just nasty. They took on the taste of a musty cardboard box and were a little chewy.

LOL probably being on a boat is a humid environment though. In the desert, they may have been fine!

 

[yzer]

Yep, even with dehumidifiers on all winter fighting the effects of humidity on a boat is a constant battle.

 

[Iffy]

... so not sure why that would make a difference?

It's easier to arrive at your desired PG/VG/nic level ratio. Just play around with a joose calculator and insert diff values/ratios, you'll see.

 

[junkman]

Well, help me figure it out. 100mg nic is 100mg.

If I am going to 20mg it is 1 part base to 4 parts additive.

What difference could it make which is the base and which is the additive?

I guess since I am using 80pg 20vg it works?

If I go to a pg base, then I will need to add both pg and vg to get the ratio. That would argue for using VG base. But since i find PG easier to work with due to viscosity, I probably won't mind the extra step of adding pg.

 

[yzer]

It's pretty easy to make 20 mg base from 100 mg VG base. Say you want 80/20 PG/VG.

For a 100 ml batch use 20 ml of the 100 mg VG base. Add 80 ml of PG and mix it up. Any flavoring you add to this later will reduce the 20 mg nicotine by the amount of flavoring by volume. This online calculator is easy to use and will help you with that.

Just skip to the second paragraph...TMI follows. I don't have nearly the experience that you guys in this thread do, actually none. I have gone bat ..... crazy on researching which base liquid I am going to buy. I have no problems with a 50/50 or 60/40 mix, PG gives me no problems so far. Suppliers are having a hard time these days keeping up with demand and all that, the one's that can provide anything right now are the types that provide a choice of 100/0 or 0/100. If my fridge had not chosen to go insane today, I was going to place an order for 500 ml of 100mg (PG or VG undetermined) when I woke up, 3/22/2013. Should have been 2 years worth, now I have nowhere to store it properly. I have priorities, all money goes into fixing the all-mighty, life providing fridge ASAP. I think I need a new PCB for it, not that it matters to this discussion or anyone reading this babble.

Junkman, do you thaw the 100% VG base (100mg?) before trying to poor it and mix? Only asking for obvious reasons, I understand the viscosity differences of PG and VG at room temp. Yzer seems to likes his stuff PG free, so I get the pre-diluting before freezing, if that is a reason. 50/50 and 60/40 treat me well, so far. I would prefer to freeze the 100mg by itself (once I have a working freezer again, lol), but you have me wondering which base is worth my time messing with. I was so close to going with a VG base for the 100mg, now I have more considerations to make. Sounds like I might want a PG base. Thanks for starting this thread, it was one of many questions in the back of my mind (which vendor???) ...

I find the VG at room temp is very sticky and thick. Using it with pipettes or graduated cylinders is pretty frustrating. I think from ease of use standpoint a PG base would be better.

I guess the VG may thin a bit if warmed above room temp but not sure how much it will thin and if that can damage the nicotine or not.
