I'm thinking about buying 1000ml of 100mg nicotine. How long can you store it? Do you keep it in the freezer or at room temp? Thanks.

How long can you store 100mg nicotine?

I'll just tell you what I have done from advice from our "resident chemist" Kurt. I have my nic base stored in 1 litre Boston Amber Glass bottles with PE caps (polyethylene or PE lined caps) in a freezer. Other caps can react to VG/PG/nic, esp. rubber or rubber droppers which shouldn't be used. You can leave some space at the top.
Mine is a AG (VG + H20 83:17 + nic) nic base and it doesn't expand in cold but may expand at room temperature some. Before the freezer, I had VG and PG based nic stored in cool, dark, dry place for two years where there was no deteriorization in vapor production or any noticeable reduction in nic although it wasn't tested. Dow Chemical rates storage of PG and VG at 18 to 24 months in cool, dark, dry place, but in many cases manufacturers will understate the storage for legal considerations. Freezer will extend that period according to Kurt and his own experience.
Diluents - pure PG and VG or AG (VG+H20) can also be stored in the freezer to extend storage times. But Kurt advises against storing pure flavoring in the freezer.

Great info. I'm about to start storing nic base and this helps.
I have some amber glass bottles with poly-cone seal caps. Also have some glass droppers but I'm not planning on using them for storage. No mention of PE designation by the supplier. By leaving space at the top of the bottle, as you recommend, will that reduce the risk of the caps reacting to the stored liquid? In other words, avoiding contact between cap and liquid is the objective?
I wasn't sure if PG/VG could also be stored in the freezer - good to know that they can. I would assume it's a good idea to use amber bottles for these liquids as well.
The space was for the possible expansion. I can't validate anything other than polyethylene caps. You can buy those caps at various bottle places but you'd have to get the right size obviously. Yes, I'd use the boston amber for the pg/vg as well. I also have my flavorings in them but just not in the freezer.
I have juice stored with no flavoring that is over three years old and it's as good today as it was the day I bought it. I just kept it stored in a cool spot.
One other consideration is opening nicotine exposes it to air and light. breaking large quantities into smaller bottles will reduce the need to expose the entire bottle to air and light. Air and light aids the oxidation process. I separate NIc into smaller bottles for storage. Then, when needed I will remove only a small bottle for use and leave the others unopened. MY

I purchased some nicotine and the bottles I bought to store it in I got on amazon and said they were the polycone caps but were not and I stored it in the freezer in those bottles but I have the correct caps now, do I need to let it get to room temperature before switching the caps out or just try to switch them real fast without removing from the freezer at all?
I broke down 1.75L of 100mg today. I have to make juice for 2 and will probably end up supplying friends so I sat down and did the math. 120ml of 100mg = 660ml +/- of juice @ 18 strength. I figured that would be the average for everybody. I like 12 but apparently I'm a lightweight compared to my circle. lol.
Based on what me and my wife go through and what I plan on making for friends a 120ml bottle will be out of the freezer and on the shelf no longer than 2 months. This seemed like a good way to go for me so I broke it down in 120ml bottles. Used blue bottles and polycone caps. I even vacuum sealed each bottle although I'm not sure that is necessary. Seemed like a worthwhile step though.
From what I've read from the very helpful resident chemists, I should be good for years. I really appreciate the passion and willingness to share that members have here. It's made a huge difference in my learning curve. I felt totally confident doing what I did this morning and I have this board to thank for it.
Right now I have a 2.5 year supply sealed and ready. I'll probably double down if the FDA looks to drop the hammer.

Answer: as long as you want! We are under the general consensus that 2-3 years with proper storage (very little air in the bottles and poly-cone caps in glass bottles, cold environment) should be no problem and the nicotine should suffer very little degradation. Many of us store it in the freezer, some in the fridge, some are brave and leave it in a cool cabinet.
