Does E-Liquid Expire?
You may have noticed that some e-liquid manufacturers have begun adding expiration or best by dates to their products. The truth is that there is very little evidence that e-liquid products actually go bad. They do not grow fungus or mold like the food in your fridge. Rather, if left sitting for too long, you may find that the ingredients start to separate out, which causes a shift in the flavor. If left sitting for too long without being remixed, it may be impossible to ever get the right flavor back.
What we do know is that vegetable glycerin and propylene glycol are generally stable for up to two years in storage. In addition, we know that liquid nicotine begins to oxidize over time if it is not in a tightly sealed container. This means that even though the liquid isn’t going “bad”, it will become far less effective over time.
The best thing you can do is purchase only enough e-liquid that you can use within a two to three month period. If you plan on storing your e-liquid for extended periods of time, it is recommended that you store it in a cool, dry place and in tightly sealed glass bottles. This will help your e-liquid stay good for longer. Plastic bottles tend to let in more air and light in which can react with the ingredients and cause oxidation. Do not freeze your liquids as it will change the consistency of the liquid.
How Long Does 10 ml & 30 ml of E-Liquid Last?
Many people want to know how long a bottle of e-liquid will last. Depending on where you are, you may be purchasing bottles of liquid in 10 or 30 ml quantities. The answer is that this depends on how much vaping you do. If you are vaping at the proper nicotine level and taking average vaping breaks, you can expect to vape two to three ml of liquid per day. For many people, a 10 ml bottle can stretch for a whole week, and a 30 ml bottle can last 14 to 18 days.
It is important to note that if you are using a lower nicotine strength than you are used to, you may find that you are vaping significantly more than normal. This will cause you to burn through a lot more liquid than the average vaper. That’s why it’s important to find the correct nicotine rating to get started with up front. The type of vaping device, such as a vape pen or mod, you are using can also have an impact on how much liquid you are going through. The vaporizer brand can make a difference too.
Hopefully, this guide has helped answer any questions you may have about how long e-liquid lasts. If you are concerned about your e-liquids expiring, the good news is that the liquid itself is probably still safe for use, but won’t deliver as strong of a punch. If you notice the flavor has changed drastically, you may want to throw it out and buy a fresh bottle. If you’re trying to meter your e-liquid usage over the course of time, plan on buying a 30 ml bottle of liquid every other week or so.
