How long is the shelfing life of e-liquid?

[pimpe]

hi,

I was wondering how long can i keep a e-liquid before it turns bad or non-vapable?
And how long if i put it in the freezer?

I am look at getting some pure nicotine (990mg/ml) for mixing becasue it is so pure i will need like a year+ to finish just 25 ml ( can mix up to 1liter+ of e juice @ 18mg/ml) of it. And it gets cheaper as the size goes up.

If i get 100ml of it will last me for 5years.... only if i can keep it for that long and not turning bad.

so do anyone have any idea??


Thx

If you plan on keeping it, don't mix it. Tranfer it into sterile (or as close as you can get) amber/cobalt glass bottles with euro droppers then freeze it. Take one bottle at a time out and mix it when you're needing to make juice. As far as how long it lasts, that is still to be determined...no one really knows.

am I reading what your saying right 990mg man thats dangerous be carefull, I vape nothing but DIY and I'd be scaird to mess with anything that high without a gas mask and a hazmat suit.

I have read that just a few drops of that pure nicotine on your skin can do serious damage or maybe even kill you.

I'd stick to something much weaker if I were you.

Agreed, Nic is one of the most dangerous poisons out there in the world. It should not be taken lightly.

Unless you are a chemist, trained in proper lab technique and own the proper safety equipment I HIGHLY advise you to stick with lower concentrations of nicotine. It's just not worth the risk.

2 years is the accepted shelf life of mixed ejuices, provided they are kept in a dark, cool place. Some refrigerate.

My unflavored in freezer has passed two year mark and still seems good as new.

990 mg/mL is just a bad idea for home use. For the purpose of e-cigs and DIY mixing, you should get 100 mg/mL. You can safely mix the 100 mg/mL without needing extra ventilation and special lab equipment and without worrying about poisoning yourself.

Yeah, 990mg? There is saving money, and then there's your health.

...or your life.

I'm a field service rep & I go where they make the nicotine patches. They mix the juice for the patches there, i.e the nicotine that the OP is talking about. Even when it's mixed with the other ingredients in their kettles, it is so dangerous. Please, please, please if you handle this, be more than careful. Much better yet, don't handle it. They say at the place I go to that if you get 1 drop of their DILUTED (still pretty concentrated) nicotine on you, your heart will start beating so fast there is no saving you.

Evening on the 60 mg or 100 mg, best advise is to wear gloves. Higher don't touch.

Wondering if you got the pure stuff? I agree with the other posters that it's too dangerous to be worth it. I use the 100 mg/ml and dilute it with equal pg to 50 mg and work with that. 100 mg is probably ok, I think people are really over-worried about reasonably diluted nic bases. That being said when I dilute the 100 mg, I'm sure to be careful and put glasses on.

Pure nic is not worth the risk. I'm suprised you can even buy that!

For what it's worth, I'm pretty sure it's better for long term storage to have your nic base be in PG.

Cut and Pasted from Wiki

The LD50 of nicotine is 50 mg/kg for rats and 3 mg/kg for mice. 40–60 mg (0.5-1.0 mg/kg) can be a lethal dosage for adult humans.[56][57] Nicotine therefore has a high toxicity in comparison to many other alkaloids such as ......., which has an LD50 of 95.1 mg/kg when administered to mice. It is unlikely that a person would overdose on nicotine through smoking alone, although overdose can occur through combined use of nicotine patches or nicotine gum and cigarettes at the same time.[58] Spilling a high concentration of nicotine onto the skin can cause intoxication or even death, since nicotine readily passes into the bloodstream following dermal contact.[59]

Notice that it says 40-60 mg can be fatal for adult HUMANS. So if it's 20 drops per ml (lets just say that) then that's 50 mg in one drop, and that may kill you. If it's 30 drops per ml then it's 33 mg, which could send you to the emergency room and possibly kill you. Just get 100 mg/ml, that would be 5 to 3.33 mg per drop (which should then be diluted further fora working bottle.)

Imagine if you just got splashed somehow, you would be DEAD with pure nic.
