PG nic is better than VG nic. Use PG if you can, or 50:50 if you have to.

thats why i was wondering about the pg nic, and rather go with vgIntresting that you would use pg at that ratio. So pg based nic and pg based flavourings. That would be most of the 30%. At high nic mixes you will not be able to make the ratio for complex mixes.
Just asking?
No no, don't stress man, I'm not that sensitive
You're 100% right. The factors for stability put very simply - are concentration, VGG ratio and other ingredients.
For example the ingredients that go into my Custa Nise (Sorry if advertising, speaking about experience here) cause nic to start oxidising almost instantaneously. No matter what I do, I get around 1 week of oxidation in a day or less. Then another example would be comparing 18mg and 3mg. Of course there's more nic to oxidise in the 18mg, but it's also happier to react with the VG and oxygen in the bottle.
I can show you mixes that I've prevented from oxidation - 18mg bottles that are lighter than whiskey coloured after a month. There's a slight gradiation from the surface of the juice where it is exposed to some oxygen, but besides that, my methods slow down oxidation by a huge amount.
You can put juice in a cupboard for a year, and it'll be fine BUT the nicotine will degrade, the TH will decrease and there will be a hint of cat piss to your juice (especially at higher strengths). When customers approach me about this, I always explain that if my juice seems a bit strong, it's because the nic has been kept in excellent condition - that way you can vape a slightly lower strength while getting a satisfying TH etc.
Again, this is relatively anecdotal, but it is my experience and I'm quite serious about how I deal with these things.
My understanding is that the higher the PG content the longer your juice will last - PG being a good preservative. I can see it with my older juices - the very high VG ones are starting to slightly deteriorate.Thanks @Mike
But just a question and im not trying to debunk your testing, I am nowhere near as experienced as you at working with these ingredients
But if you say nic is more stable in PG, surely when you mix it with VG to make a juice, then it will go "unstable".
And if mixed juices can be kept for say a year in a dark cupboard without much problem (as i understand), then surely the VG Nic should also hold out for about that long in a dark cupboard?
Or am I missing something?
