How To Preserve E- Juice

In this brief guide, we are going to answer the question “How to preserve e-juice?”, and discuss the different methods of preserving e-juice and the potential implications of preserving e-juice.

How To Preserve E Juice 

Short Term E-Liquid Storage

The ideal place for short-term storage is a high cupboard. The reason is this not only keeps it out of reach, but it’s also nice and dark. It will probably be away from any sources of heat.  The cupboard must be out of direct sunlight that is not over a radiator or next to your oven, that would be an ideal storage spot.

One can also use a storage box, and if it’s lockable. There is nothing to worry too much about keeping it somewhere high up, either but I can do that anyway, to be as safe as possible.

To minimize the amount of air it’s exposed to, one should ensure that the cap is firmly screwed on. One can even squeeze plastic bottles before screwing on the cap to remove most of the air. If a large bottle of juice that’s half-empty is there, then one can also fill up several smaller bottles with it so that most of the e-liquid is in full bottles with little room for air above it.

Long-term storage of e-juice

Can e-liquid be stored in the fridge or freezer?

For long-term storage, there are a few extra considerations, but the message is largely the same. Minimizing the amount of air in the bottle is even more important, and you should switch to glass bottles.

The same basic rules apply, but storing e-liquid for the long-term does bring with it some potential issues. They can be as follows:

Firstly, while plastic bottles are absolutely fine for shorter-term storage, they aren’t the ideal solution over the long-term (more than a couple of months): thus, using glass bottles instead is preferred.

The reason behind this is that the plastic can interact with the e-liquid, with reference to heat if said – any chemical changes will alter how the e- juice tastes. Additionally, although plastics prevent most things from passing through them, some air can get thorough or as said they’re “permeable” to some gases. Also, it is known that air degrades e-liquid, which isn’t a good thing.

The amount of air can get through depends on the type of plastic – generally speaking, higher-quality plastics are less permeable to air – but glass is a way better approach for both removing the air permeability and minimizing any interactions with the container.

Additionally, for long-term storage, using the fridge is said to be ideal. This is for the same reasons why refrigeration or freezing of most foods is less likely to happen because the molecules have less energy, and bacteria don’t like cold temperatures (although PG is anti-bacterial anyway).

Freezing or refrigerating e-liquid is absolutely fine. Chances are that e-liquid won’t actually freeze, but when experimented with one e-liquid there seemed to be some loss of flavor.

The only thing to keep in mind is that having the e-liquid in a fridge or freezer will make it thicken up, so one should allow it to warm to room temperature before trying to fill up with it and vape. 

The e-liquid won’t freeze, since both PG and VG are known to have low freezing points. (While pure VG would freeze at normal freezer temperatures, this would only happen if your juice was over 80 percent VG.)

Finally, keeping the juice in the fridge or (ideally) the freezer will maximize its lifespan. The only problem is that it’s harder to keep kids away from a fridge or freezer, so you’ll either need a lockable box, a high shelf or some vigilant parenting.

Keep e-juice away from kids and pets

The other set of considerations is when one is storing e-liquid related to keeping it away from curious kids and pets. Nicotine (like many other household goods) is poisonous and there can be tragedies if one ain’t careful with the e-liquid.

“Child-proof” actually means “child-resistant,”  and it’s far from a fool-proof solution. A cap can be termed as child-resistant if most children can’t open it if left for a short period of time.

To elaborate, if one leaves their kid with something in a child-resistant bottle for more than about five minutes – medicines and e-liquids alike – he or she will stand a good chance of being able to open it, and some kids will open it in a much shorter time. One should never rely on a child-resistant cap to keep the kids safe.

The solution is keeping the e-liquid somewhere children or pets can’t get to it. A high cupboard, a lockable box, a high shelf, or anywhere out of reach is absolutely fine.
