Bad Nicotine

I use 14-16mg in my nic base, so I stored 14.5ml in 15ml bottles. I take that out of the freezer and let it thaw (it is in PG) and then make my 70%PG/30%VG base, works for me - and yes I shake it.

In another experience, several of the 125ml bottles, still sealed to this minute, have somehow been 'filled to the top' or have absorbed water vapor through the sealed lid and wrap. I opened one to have it dribble out. Now there is no majic bean man that teleported into the bottle and added liquid of some sort. /satire However the bottle is more full than it was when it was sealed and sent. This can only mean the seal is no longer of value, and the VG is absorbing oxygenated water molecules through water vapor in the ambient.
We did not freeze nic as some do now. fyi

I'm guessing the bottles where filled during a time when it was colder than now, and then when the temp gets hotter, then the vg will fill more in the bottle(opposite of water)...

@All

I always shake my nic when I first get it and only that one time. I do it as a precaution, since I do not know if the vendor have bothered investing in proper mixing equipment, and/or bothered to leave it in the mixer long enough for obtaining a fully homogenious solution. If the nicbase was fully mixed from vendor(which it probably is 99% of the time?), then there where obviously no reason to remix(shake) it, but we simply don't know that for sure and that's why I do it...

I've never seen any reports of nic properly stored, cold and well filled in glass bottles, degrading badly. Based on user titration tests. Regardless of shaking. So I shake as I think might be warranted. I work out of small bottles (30ml) so the frequent opening only affects that small amount. The rest is in the freezer.

My own titration tests are in range.
