Taking care of eliquid

[Hardpack]

I'm also curious if freezing would be o.k. I'm leaning towards yes but would rather wait for a chemists point of view. Actually I'm not aware of anything that freezing will ruin. There could be times during the shipping that our liquid could freeze.

just depends on what time of year it is i guess

Anything suspended in PG_a bridge for specified polar/non poloar molecules_ refrigeration should be fine(PG is an alcohol with OH bonds). If anything solid comes out of solution then just take the juice to room temp and mix until all solids have redissolved. I have only seen sugar type solids and some solid extracts come out of PG under refrigeration and if this is the case the safety of vaping those liquids rich in sugar might be in question.....

I refrigerate my juice and no solids have yet to come out

Just talked with Beci Chen from Bestecig.com and he told me they store there e-liquid in a fridge but also a cool dry place works also and shelf life is about 2 years according to him .

Cool and dry works well.

I guess it dosn't help that I keep mine in my pocket all day.

I would think simply due to the fact that you are inhaling something into your lungs that you would want that product to be clean, sterile if possible. For example, if your hands are not washed properly before handling things that come into contact with the liquid you could transfer all kinds of bacteria etc to the liquid, and of course then you would be inhaling that. For the same reasons I would think it would be wise to keep it tightly covered, both to keep contaminates out and to keep the liquid from evaporating.

I had been thinking maybe I could mix up one batch of liquid and not have to mess with it for....x months. I am rethinking that in light of this discussion. I think I can probably be bothered to do the mixing once a week. And I will sterilize my containers as part of the recipe. This is one of those things that may not be necessary, but it is also something that cannot hurt, and may well keep you out of a heep of trouble.

No loss of strength noticed here with e-liquid stored at room temperature in a closed bottle for 6 weeks....I agree with the general consensus on this thread that the liquid seems to be pretty stable. Though to be a little safer, my spare 30-ml bottle is in the fridge.

As for freezing, I'd think it'd probably work, but obviously you don't want to commit a huge stash to any risk. Maybe a smal-scale experiment would help - try freezing a small amount in a suitably small, sealed container (plastic, not glass, or it might crack). The problem might be getting the container - you could wait till a bottle of e-liquid is nearly empty and just freeze that, or maybe use a contact lens fluid container (wash it out well first). Generally, it's the freeze-thaw cycle that does the damage to most things, rather than the prolonged duration in the cold, though you never know. It'd be interesting to see whether the stuff will freeze at all, using normal domestic freezer temperatures (around -20 degrees centigrade).

One confounding factor could be oxygen - a small amount of liquid in a relatively large container is exposed to a relatively large amount of air, and therefore oxygen, which might conceivably oxidise some ingredients. But you're not going to freeze your main stash in that fashion, you'd be freezing filled bottles which contain a lot less air - so if you can't find a really tiny container for your experiment, then if the experiment shows no degradation, your stash will be safe, but if the experiment shows it goes off, it doesn't really prove anything.

It's probably fine to just store it well-sealed in a cool, dark place, rather than take any risks by sailing into uncharted waters.

Cartridge stability may be another matter - Gamucci recommend consuming within 2 weeks after opening. That might be just to sell more carts, though my own experiences suggest they may well deteriorate. Presumably there's more scope for oxygen to attack the liquid in a cartridge. That applies to the ones you refill yourself as well.

But it's difficult to be sure - somebody's mentioned that the brain can adjust to the flavour of your favourite e-liquid over time, and make it seem like your stash is losing its strength. And rather like cigarettes, I find the first one of the day can taste stronger than after I've had a few. I'm seriously considering abstinence just to heighten the pleasure when I start again.

If anyone is interested in professional advice about eliquid then this thread should be of interest - e-liquid manufacturer - supply over 90% of the e-liquid on the market

Dekang have been answering questions about their eliquid there.

They say that a cool dark place with the lid firmly sealed is the way to store. It doesn't seem to matter if you put eliquid in the fridge/freezer or not. (I might have misread so double check for yourself if you want to be sure.) This might only apply to their formula which I think is based on propylene glycol.

Thanks for the info Kate. That thread was an eye opener. It's nice to have contact with the largest player in the market.
