Quick help on nic
Hi
I'm going to be buying in stock of 72mg nic to freeze and have a quick question.
I intend to make ejuice with an 8mg nicotine strength, how many bottles of 30mg juice will 1 litre make?
The reason for asking is to Ensure that I buy enough to last 4 to 5 years, based on a daily consumption f say 15mg of juice.
Thanks guys, I really need to get the amount I order right.

RE: Quick help on nic
1 litre of 72mg nic is 72000mg of nic. So 30mg juice is 72000/30=2400ml

At 15ml of 8mg juice a day, you are consuming 120mg of nicotine a day, roughly 3600mg a month or 43830mg a year.

3 litres should (just) see you through 5 years.

RE: Quick help on nic
Its not going to freeze is it ? if you buying it in PG(Antifreeze) or VG :0

Enemy
1)     Oxygen     2)     UV Light     3)     Heat

Split the 1L liquid up into smaller brown bottles to store, then you wont expose the other bottles to air each time you open for use.

Freezing point -79°C.
This means Nicotine won't freeze unless you can get it to -80°C or below.

However the medium in which the Nicotine is contained will freeze at it's respective temperature.
PG -60°C
VG +17°C

Rate of degradation.
Nicotine in PG solution is noted to be stable at room temperature (20°C) when exposed to air and (indirect) sunlight for up to 2 months with only a 2.1% drop in concentration.

This indicates that an open container of Nic/PG base at 54mg would degrade to approximately 52.8mg.

An open container of PG e-liquid at 18mg would degrade to approximately 17.5mg.

Hi Kingjohn,
I am planning on freezing it as I thought lower temperatures would slow down the degradation of the Nic?

RE: Quick help on nic
It does - but it is best to keep oxygen away from it. The rate of any chemical reaction (Which nic degradation is) will halve for each 10C difference in temperature. So keeping it at -20 in a freezer will reduce the rate of oxidation by a factor of 16.

Keeping it in brim full bottles with no air space at the top in the dark and at low temperatures will dramatically increase its life.

RE: Quick help on nic
Oh yes, definitely lower temperature will help stop the degrading problems, but it dosnt freeze sold if you know what I mean unless you can get it to -80°C or less ha ha

I don't think anyone has had it 5 years to say :0 I just keep mine in a fridge, dark brown 100ml bottles, label came with it saying it would be fine for 2 years.. but thats just being safe, if 72mg dropped to 71mg after 3 years it wouldn't be a big problem.

Yours should come with a label, or you could ask them.. they might know :0

Sorry Don posted before I hit reply

RE: Quick help on nic
I was looking at Creme de Vapes storage package, bloody expensive but it comes in brim full bottles and sealed in a Mylar bag with an oxygen scavenger in it. 
As I said it is expensive but if it will last 5 years + that's got to be a good thing isn't it? Is the extra money worth the added protection? What do you guys think?

RE: Quick help on nic
It certainly won't hurt. CDV have a good reputation - I bought my first ecig from them. Smaller bottles are likely better than larger ones as otherwise you are decanting to working stock all the time. I tend to keep 50-100ml as working stock and just defrost more if I've a big batch of juice to make.

RE: Quick help on nic
In my experience VG base lasts better. However, others vehemently disagree with me and insist that nic in PG lasts better in the freezer. Nic in VG straight from the freezer is not usable as you can almost cut it with a knife. PG can be used straight from the freezer though it is pretty gloopy.

In general, the base is not really an issue once you are below 12mg/ml nic.

When I buy a gallon next month it will be in VG for what that is worth.
