One of the many advantages to vaping over smoking is that you can get your nicotine fix in a wide variety of fun flavors. When your favorite flavor starts to get boring, you can easily switch it up.
If you’re one who likes to switch up your flavors a bit, you’ve probably found that you have several partially used bottles of e-juice lying around. If you’ve ever gone back to an old flavor after a while, you may have realized that the taste is no longer as good as you remembered it. It’s not a memory issue; storing e-liquids improperly can cause them to lose their flavor.
The effect might be that it’s slightly blander than you remembered, or it might even taste completely disgusting. That’s because to get the flavors just right, requires quite a bit of complex chemistry and those chemical compounds can break down over time—especially when you’re not taking care to store your e-juice properly—resulting in diminished flavor.
The following tips can help you store your vape juice safely and in such a way that you can go back to them days, or even weeks later and enjoy the same great taste that you remember.
Three Factors that can Compromise your e-juice flavors
The three things you want to be mindful of concerning the flavors of your e-juice during storage, are heat, sunlight, and oxygen.
When a liquid reaches higher temperatures the molecules that make up the liquid have more energy and can react and interact with other molecules in different way leading to a breakdown of chemical compounds into smaller components which can in turn affect the flavor.
Keeping oxygen out of your e-juice completely is impossible. Even a full bottle has some air in the top and as you use up your e-juice, the ratio of oxygen to e-juice in the bottle goes up. The problem is when your vape juice is exposed to sunlight. The sun’s UV rays energize oxygen molecules causing them to interact with the nicotine in your e-juice. When nicotine loses two hydrogen atoms and gains one oxygen atom, it becomes cotinine. This isn’t harmful but in the long term can result in a lower nicotine content that your body will sense. In short, your body won’t be getting enough nicotine to satisfy your craving.
Glass vs. plastic
If you’re going to be storing e-juices at all, make sure you’re using higher grade plastics—or even better—glass. The lower the grade of plastic the more permeable it is meaning more exposure to outside air and more flavor loss. Plastics can also interact with chemicals in your e-juice affecting the flavor. Glass is less permeable than even the highest grade plastics which makes it superior to any other bottle for the storage of e-juice.
Short vs. Long Term Storage
For short term storage (think several days rather than weeks), keeping your e-liquids in a dark, cool place like a cupboard should be fine and you won’t notice much if any difference in flavor when you come back to it.
If you want to set aside particular flavors for longer periods of time, like weeks or months, then you’ll have to store them in the fridge where the molecules will have much less energy and won’t react with each other and break down nearly as fast.
Keep out of Reach of Children
e-Liquids are for adults only. Nicotine is an addictive substance and should be kept out of the hands of any children who may be in your home. In concentrated amounts (which is what children would get if they drink e-juice right from the bottle), nicotine is even more dangerous. As vaping becomes more popular, accidental nicotine poisonings do as well. In 2015 alone, poison control centers reported more than 2,500 cases of accidental nicotine exposure involving children. Wherever you’re storing e-juice, make sure children can’t gain access to it. The child-resistant caps aren’t completely child proof and given enough time, children can get them open.
