There are definitely a lot of interesting questions that are asked everyday in regards to vaping and everything else involved with vaping. One of the main components to vaping is E-Liquid, and a question that is asked very often is whether E-Liquids expire or not. The answer to this question is YES.
As of right now there are no studies showing if expired E-Liquid is harmful or not, but we still recommend to follow the expiration date listed on each bottle to be safe.
It can get expensive continually purchasing E-Liquids, so we want to make sure you get the most out of each bottle you purchase! Below you will find more information in regards on how to know whether you E-Liquid has gone bad, and how to keep your E-Liquid good for as long as possible.
How Do I Know If My E-Liquid Is Expired?
Now there is no official expiration of E-Liquid established as of now, but you are safe to base the life of E-Liquid off of the PG, VG and Nicotine, which if stored correctly, you can expect to last for 1-2 years.
Many factors can change whether or not different E-Liquids will expire quicker than one another, such as the different flavorings used. We put a 1 year expiration on all of our liquids to be safe, but that is just our general recommendation.
There are many signs that will help you know if your E-Liquid has gone bad. Always keep an eye out for each of the following before vaping on ANY E-Liquid.
Is Your E-Liquid Changing Colors?
There are times where E-Liquid will change colors slightly, in this case this is not something unusual and you are most likely safe to vape it. BUT if you E-Liquid color changes significantly, then you should be weary that your E-Liquid has gone bad. We recommend that if a big change in color does happen, that you dispose of it and do not vape it.*
E-Liquids will change colors due to the common chemical reaction known as oxidation. Nicotine itself is a very reactive substance, and can cause your liquid to change color when it reacts to other ingredients, or if exposed to air, light, or heat. Oxidation is a natural chemical reaction which does not alter the taste or overall vaping experience, which is why your e-liquid is still okay to vape after a slight change.
Is Your E-Liquid No Longer As Thick As It Used To Be?
The thickness of each juice will vary based of the company it came from, and the whether there’s more VG or PG in the mixture. The more VG your E-Liquid has the thicker the juice will be, whereas more PG results in less thickness.
If you notice that your juice has sediment (matter that settles on a bottom of a liquid) on the bottom of your bottle after a short period of time, don’t worry this is common. All you need to do is shake the juice and everything should blend together again.
If you find that after shaking the bottle that the sediment does not blend all together again, then you will need to dispose of this juice, it is no longer vape-able. This E-Liquid was most likely exposed to air or heat, and is not recommended to vape, even if the expiration date shows that the product is within its limits.
You will notice that your juice will be a thinner type of liquid, verse the thick liquid you purchased. The juice will most likely be runny and pour straight out of your bottle rather than dripping slowly out, as it normally would.
Does Your Juice Smell Funny?
If for any reason you somehow keep a bottle of E-Liquid around for 1-2 years, one of the first things you should do is smell it. You most likely already know what the smell of this juice should smell like, but if you notice it has a different, funny smell, then it is recommended that you throw it away. Just like food, if you notice something drastically different than when originally purchased, it is always a safe call to dispose of it.
How Do I Properly Store My E-Liquid?
Properly storing your juice will lead to a longer shelf life. Liquid can get very expensive when you are continuously purchasing different flavors and brands, we all want to get the most out of all the juice we buy!
Here are some steps you can follow to store your E-Liquids:
Keep Away From High Temperatures And Light
Making your own liquids? Aim to use tinted glass bottles to avoid contamination and help preserve the shelf life. Even if you don’t make your own juice, try to look for companies that offer tinted glass bottles to help prevent the light and heat from getting to your juice.
Hopefully you have a refrigerator around, because the best spot to store your E-Liquid is in a dark, cold and dry place. If for any reason you don’t have a refrigerator to use, you can always put your juice in a box, and put that box inside a drawer. Make sure that if you don’t put your juice in a refrigerator that the storage place remains cool and dry.
Always Keep Your E-Liquids Sealed
High temperatures and light aren’t the only factors that affect the shelf life of your juice, you want to eliminate the amount of air that is constantly being exposed to your e-liquid.
Oxygen reacts with nicotine to produce cotinine, which is the oxidation process of losing two hydrogen atoms and gaining one oxygen atom. This results in a loss of nicotine in your E-Liquid.
You won’t be able to completely avoid oxygen getting into your bottle, but proper storing will help prevent this as much as possible.
Conclusion To E-Liquid Safety
It is very unlikely that vaping expired E-Liquid will do any serious harm, but due to the fact that there are no actual studies done on this subject, we recommend to always make the judgement call. It is always better to be safer than sorry.
We will always recommend 1 year on our juices, but once again there are different factors that come into place that can change the length of shelf life.
Juice can get expensive over time, but is getting sick really worth the $5-10 (most likely got some use out of it before expired).
