PG vs VG Nic eJuice - PG has better shelf life, why purchase VG?

[MagicMike]

Hello,

After doing a lot of reading I purchased my 100mg NIC in PG as I heard it has a much better shelf life than the VG. I see quite a few post where folks purchased their NIC juice in VG. You can easily get to 50/50 vg/pg even with higher nic concentrates with 100% PG nic juice.

Is there any reason you would want to order NIC juice in VG?

I recently purchased a bottle of VG nic to make 100% VG e-liquids just for my own experiment, but some people are very sensitive to PG and want little to no PG in their liquids. Generally I buy PG nic, I'm not sensitive to either one, it's just easier to work with viscosity-wise.

Yes.

Some people are allergic to PG or sensitive to PG.

Personally since I use a lower amount of VG (30-40% total volume) I find it more economical to buy my nicotine base in VG. Also unless you're buying in really really large quantities shelf-life should not be a problem. If you're storing it because you're afraid of the FDA you can always store either in the freezer for a good long time in glass bottles (amber is preferred).

Neither PG or VG will freeze into a soild at deep freezer temperatures but they will become gel-like and react with oxygen less.

I find keeping no more than 120ml of nicotine base out (in a cool dark place--I don't have kids so a box in my chest of drawers is great) can keep me in juice for nearly four months (far shorter than the opened shelf life at room temperature for both VG and PG nicotine base). Of course I also mix frequently in small batches.

VG nic last longer in the freezer due to it turning into a rubber cement like consistency (I can turn my bottle upside down and all the vg stays where it was) according to a few people on here. PG just turns into a viscosity similar to VG at room temp when you put it in the freezer.

If shelf life is the only factor you're using to determine whether to use PG or VG you may be confused. There are differences in PG and VG, not the least of which is that many people have a PG sensitivity.
