Cutting 100mg Nic in half to 50mg, then storing. Good or Bad?

[smacuser]

I really couldn't find much on this.

I bought a liter of 100mg and a liter of PG. My plan is to mix it together, then fill up 3 500ml and 3 125 ml amber glass bottles. The rest, I'll put in 2 60ml bottles and put it all in the deep freezer. I'll mix my first bottle with what's left over with some VG.

I feel that cutting it first will make mixing easier in the long run.

1) Is it okay to cut 100mg nic before storing?
2) If so, can I mix it in a large pyrex pitcher?
3) If so, should I stir it together with a wisk, or use an electric mixer?

Any advise on this would be appreciated.

Mix 50/50 in containers and shake to mix.
Mixing in the open with a whip or mixer introduces more oxygen into the liquid which causes it to degrade quicker.
shake the 100 mg nic well before pouring into bottles to ensure that it is mixed well.

I figured if I poured both bottles into the pitcher first, then I'd know it would be 50/50 right away without having to measure it.

In order to shake the container, I feel that I'd have to leave some headroom. I read I'm suppose to leave as little headroom as possible.

Leave just a little headroom. Shake and keep turning upside down and right side up.
Besides it will have plenty of time to mix won't it?
If it is PG based nic and PG you are mixing it will mix well.
Just be sure the 100 mg nic is mixed well before you ix it with the PG so you get a consistent nic level.

I read in one of Kurts posts that it is best to freeze at the higher strength and not cut it down before freezing/ storing. That post is somewhere on this forum. You could probably find it with a search.

Now that I posted this question, all of a sudden I am finding a lot of folks mix with 100mg for the easy math.

Though, I read somewhere 100mg degrades faster than lesser strengths.

Nope. Most everyone just pops 100 mg into the freezer or distributes it out to glass and puts in freezer.

In his 2016 sticky about freezing he makes no mention that the mg/ml ratio has any impact on long term freezer storage:

My nic came in a plastic bottle, so it will definately go into glass. I'll just have a couple of extras when they arrive.

Maybe I read it wrong...

"Few last points to cover – shelf-life varies largely by nicotine strength, as well as PG/VG ratio. Higher nicotine strengths will possess more nicotine molecules, less likely to be completely solvated by their carrier (PG/VG). Put simply – 100mg/mL formulations will keep for less time than a 24mg/mL formulation. PG is also a much better solvent for this purpose – it has an extremely low viscosity, will dissipate dispersed oxygen bubbles quickly (say that 4 times fast!), and has a longer shelf-life chemically (2 years from DOM, vs. VG – 1 year). Thus some may only see a short shelf-life for a 100mg/mL solution kept on a shelf compared to a 24mg/mL solution kept in multiple frozen aliquots. Remember, nicotine solution solvated in wither PG or VG WILL NOT FREEZE!"

They are resellers, they do not really know their stuff.
For storage it is a little bit better to have a more concentrated solution. To save space in a freezer it is much better to have concentrated solution. I do not see any real reason to dilute nicotine before freezing.

That alone is so convoluted I have no idea what they are getting at. It seems to imply that lower mg/ml solutions when frozen do better than higher mg/ml that isn't frozen.

So.... what's their point?

I was under the impression that nudenicotine is a highly regarded supplier. Though, I bought my nic from Vapers Tek.

cutting in 1/2 with PG or VG is fine ... if you are more comfortable working with 50mg, go for it.

nice choice on the Vapers Tek.

Thanks Willy, I was hoping you'd show up.

Do you mix with straight 100mg?

Now, I'm thinking about saving 100mg in a 500ml bottle and cutting the rest as I am learning.

yes, I mix using 100mg ... your thinking is good though, stash 500ml of 100mg away and cut 500ml into a liter of 50mg.

They are and it's where I purchase from. I have read that entire blog post at their site before and it's a bit non-sensical if not confusing. The simplest explanation is most likely because they are in the business of making product and moving product, and not in the long term storage business.

If I were going to cut a large quantity of 100mg I would acquire a 1 gallon container of distilled water as typically sold in a plastic milk container, mix and shake. They are only a buck or so and have the advantage of not being contaminated. You could do the same with an emptied 1 gal milk container but you have to make sure it's totally clean. Better to start with a clean container. Glass would be better but I can't think of many suitable 1 gal size glass containers commonly available .

Like others I would NOT cut the nic and I would ignore nudenic's advice to store it cut.

I think this is being way over-thunked. The bottom line:

Freezing is good. This isn't in dispute.

Exposure to oxygen is bad. So if you are doing any mixing, stirring - whatevs prior to freezing - use the method that is least likely to introduce oxygen. Stirring or slowly tilting a bottle back and forth to mix is good. Rapidly shaking the bejeezers out of it - not good.

Exposure to oxygen is bad #2. Follow Kurt's advice on filling bottles going into the freezer. Allow a small amount of air space at the top - which will be important when thawing - but don't pull an OCD fit about it. As he said - we're only talking about a few CC's of air at the top of a bottle confined to a very small surface area of exposure to the nic. (Assuming you are using something like Boston rounds and not canning jars.) It's not like 5 cc's of air at the top of a bottle is going to "eat through" an entire bottle of nic. It's doesn't work that way once it hits the temperature drop in the freezer.

As Kurt has been following and researching this topic since at least 2009 that I've seen, and his most recent conclusions have been put up as a sticky, if he saw any pertinent reason to qualify that the mg/ml concentration makes a difference to the quality of long term storage I'm sure he would have mentioned it - but he didn't.

No exposure to UV light, in glass, minimal air at the neck of the bottle, in the freezer. That's the short list of important stuff.

VG versus PG, nic level concentrations... Make yourself nuts obsessing over those last two points - but that won't get it in the freezer any faster either. IMO PG versus VG as "better" for freezing is still controversial. Myself and many others can't do PG so for many of us that's an irrelevant point. And if you just don't want to deal with high concentrations of nic - and some people don't - not seeing the critical mass problem there - once it's in the freezer.

P.S. You can get large glass jugs for mixing, from some of the same places you buy any bottles at. They are many times called "Growlers" as used for beer making. On-line they are expensive to ship so if you have a nearby shop that sells beer brewing & wine making supplies check them out.

Just my experience:
Every 8-9 months I'll thaw out a 125ml, 100mg/ml, mix it down to 14 bottles of my 7mg base.
Re-freeze, then thaw and use a bottle of base about every 20-30 days.
Also have some 3yr old, 48mg/ml nic, that I do the same.
I don't experience any issues mixing/using, this way.
Although the 7mg base is only stored about a year.
