Hi. How long can i expect to keep a big bottle of nic? Where is best storage for longest shelf life(fridge?)? I dont want to order 250/500ml and have it go bad before i can use 1/4 of it.
Thanks.
Thanks.

Some people store it in a fridge, some just in a dark spot. Some put it in the freezer ... It should last long enough
Best to transfer it to smaller glass bottles, for incremental usage. Best not freeze in some of the hard plastic bottles, as they may crack in the freezer. I transfer my nic liquids to 30-50 mL amber bottles, store them in the freezer, then just take one out at a time, bring to room temp, and dispense as I need it.
madvapes has a study on-going testing the different areas to store nic. they have a test with 4 different areas. fridge, room temp, window sill, and window sill open bottle. i believe they are several months in, with some interesting results. i suggest to check it out.
Nicotine Concentration Over Time / Mad Vapes Blog
There's the latest test I can find, from late July. I'm surprised that open bottle windowsill storage has dropped the nic by only a bit more than ten percent in four months...but I'll still store it in the refrigerator, thanks...

Ill do that then ill get a small refrigerator from Home depot I prefer keeping this stuff away from regular produce refrigeration compartments.
there is a detailed process. theres even an ECF thread that shows you how to do it on your own. sorry but i dont not have the link.
I can understand that! I put mine in the normal, regular refrigerator with all the food--but I put it in a very thick freezer bag to avoid any possible contamination of food in there.
I keep 30 ml out at a time for use. There's no way it'll last anywhere approaching three months, so room temperature storage out of sunlight in my home office is just fine.
thanks for information. i think ill break down into smaller glass bottlers and freeze em.
Much of the issues around storage are more cosmetic, that is, it takes only minute quantities of nicotine-oxide to strongly color a liquid. Depending on the nature of the pure nic used to make the liquid, and the viscosity of the carrier, tobacco flavors may bloom over a long time where they were not present initially. Neither of these will significantly change the nic content unless there is a lot of sustained agitation, with O2 continually being introduced. Thinner liquids will yellow and change flavor faster than VG liquids, and cheap nicotine, which contains other tobacco compounds, will change faster in color and flavor faster than pharm grade nic.
I am a chemist, and so I like to follow procedures that optimize preservation at new condition. My nic is virtually all VG-nic. I have 35 mg VG in the freezer that is almost 3 years old, and shows no coloration at all. Thus the nic content is unchanged, since it takes almost no nic-oxide to yellow a liquid.
On the other hand, some 36 mg PG from totally wicked after being freezer stored for 2 years had turned orange, but it had developed the most wonderful tobacco flavor. Pity I cannot vape PG. It was delicious all on its own...but some would look at it and say YUCK. It was not because PG is thinner, since I also had some Decadent Vapor 54 mg PG (pharm grade nic) that didn't change at all in two years of freezer. Seems to be the nic itself.

Just picked up this fridge from home depot should be good enough.
