How Long Does Vape Juice Last?

How Long Does Vape Juice Last?

You have just purchased a new vape pen, some e-liquid, and you are excited to try it out. The first thing on your mind is how long does vape juice last?

Bear in mind that vape juice is a liquid that comes in many different flavors, nicotine levels, and PG/VG ratios. However, how long does vape juice last? This article will go over the shelf life of e-liquid and what happens to it when it’s left out or in storage for an extended period of time.

Are There Any Rules and Regulations Around E-Liquid Expiration?

There are no legal standards in place for the duration of expiration dates for vendors or e-liquid makers.

Since e-liquid contains a variety of chemical components, the expiration date may vary from one brand to another.

The Food and Drug Administration (FDA) states that all vapor products must have an expiry date on them if they are imported into or manufactured in the USA. They also require that these products feature on their labels information about storage conditions before using it for vaping purposes.

Are There Any Rules and Regulations Around E-Liquid Expiration?

The FDA has not released any specific guidelines for e-liquid expiration, but they recommend that consumers store their vape juice in a cool, dark place and away from children. Unfortunately, there is no definitive answer as to how long vape juice will last. Some users have reported that their e-liquid remained fresh for up to two years when stored properly, while others have experienced a decrease in flavor after just six months.

Also, there is no explicit shelf life mentioned in TRPR (Tobacco and Related Products Regulations) governing rules and regulations. There are non-legally binding e-liquid shelf-life standards that exist. This is a suggested timeline for manufacturers to conduct product stability tests to ensure the shelf life of their products.

However, since e-liquid is deemed “shelf-stable”, this date is rather lengthy. The shelf life of an e-liquid after it has been produced is generally two years. This date may be shorter if the bottle of e-liquid is spilled or opened incorrectly.

The ingredients used in an e-liquid might have an impact on the expiration date. PG and VG, which are commonly utilized as e-liquid diluents, are two key factors to consider [1].

The Bottle Type Matters: Plastics vs. Glass

The type of material that is used to hold an e-liquid can have a major impact on the shelf life.

Plastic bottles are commonly made from polyethylene terephthalate, which allows them to be lightweight and shatterproof.

The Bottle Type Matters: Plastics vs. Glass

However, plastic containers do not protect the contents inside as well against light exposure or oxygen because they are more permeable than glass. This means that colors might fade faster in plastic containers compared with glass bottles. Because it does not provide the same resistance to oxidation while being cheaper to produce (and thus less costly), plastics also tend to impart flavors into other liquids stored within.

Glass tanks allow for better insulation properties when storing/exposing vape juice over extended periods of time.

The color spectrum on the container does not affect its shelf life as much because all colors will fade rather quickly under UV exposure — including darker shades like black or green [2].

How Long Does PG E-liquid Last?

Propylene glycol is a colorless and odorless liquid that is generally used as the base for nicotine levels in vape juices. It is also one of the two main ingredients in e-liquid, alongside vegetable glycerin (VG).

PG has a higher vapor pressure than VG does, meaning it produces more vapor upon exhaling when compared to VG. This makes PG liquids less viscous and thinner than their VG counterparts.

Since propylene glycol dissipates quicker than vegetable glycerin does, PG-based e-liquids have a shorter shelf life. The general consensus is that these types of liquids last around six months before they start to degrade [3].

How to Correctly Store Vape Juice?

How to Correctly Store Vape Juice?

Proper storage for e-liquid is key to maintaining its quality and extending its shelf life.

E-liquids should always be stored in a dark, cool, and dry place. This will help protect the liquid from direct sunlight exposure and oxidation, which can cause it to go bad over time.

It’s also important to keep vape juice bottles tightly capped when not in use. This will minimize the amount of air that can come into contact with the e-liquid, helping to prevent it from going stale.

Signs That Your E-liquid Has Expired:

Improper Storage of Vape Juice

Just like with any other consumable product, improper storage of vape juice can lead to it going bad.

There are many different ways to store vape juice. The most important thing for users is to remember that keeping their e-liquids in a cool, dark place is crucial when it comes to extending their shelf life. For best results, consider storing your e-liquid collection away from the following:

  • Direct sunlight;
  • Heat sources;
  • Moisture;
  • Dust or dirt particles;
  • Chemicals they might react with (alcohols/solvents);
If there is any sign of degradation upon opening an e-liquid bottle – such as discoloration or noticeable changes in flavor – do not use it anymore and discard the liquid.

Improper Storage of Vape Juice

Separation of E-liquid Components

If a VG or PG-based e-liquid has been left sitting for too long, there might be some separation of the components. This can happen as a result of the liquid being exposed to extreme heat or cold, which may cause some parts to evaporate faster than others.

If VG and PG have separated from each other in the bottle, there is no need to worry because it will still work normally once combined again. It just needs a bit of shaking before use!

In order to avoid this from happening, users should rotate their products so they spend equal time in storage and at room temperature. This will help maintain the quality of vape juice over its shelf life by avoiding both heat exposure and condensation forming on cold surfaces — especially important when storing liquids in attic space!

Smell and Taste Test

Though not a foolproof method, performing a smell and taste test on the vape juice is another way to tell if it has gone bad. If the liquid smells strange, like vinegar or ammonia, it’s likely past its expiration date. The same goes for any unpleasant flavors that might be detected when vaping.

If an e-liquid doesn’t pass the smell and taste test, then it should be discarded immediately. Just like with any other consumable item, users should never consume anything that doesn’t look or smell right!

Vape Juice Consumption

Vape juice is made up of two main ingredients: glycerin and propylene glycol. Both are considered safe for consumption, but it’s their use in food that makes them so popular with vape companies.

The FDA has deemed both as “generally recognized as safe” (GRAS) to eat by humans, which means they’re very unlikely to cause health problems when consumed orally – not even over a long period of time. Vape juice flavors tend to be more potent than those used for cooking or confectionery purposes, though the latter can make up part of some e-liquids too!

If you vape at high temperatures, you may burn through 60 mL each week in a matter of days. Every week, 30 mL of juice may be burned by vaping between 50 and 100 W with an average amount of use. Wattage is not the only factor that influences consumption; temperature also plays a role [4].

Vape Juice Consumption

DTL vs. MTL Juice Consumption

The lifespan of your vape juice will depend on how you consume it. Direct to lung (DTL) vaping results in a quicker nicotine hit and uses more juice, while mouth to lung (MTL) offers a slower release and lasts longer.

If you’re looking for the most efficient use of your juice, MTL is the way to go. However, DTL provides a more intense flavor experience, so it’s up to you to decide what’s best for you [5].

No matter which method you choose, make sure to keep track of how much juice you’re using and buy more when needed. Vape juices can last anywhere from a few days to several weeks, depending on the brand, flavor, and amount you use. As always, it’s important to keep your vape juice in a cool dry place for maximum lifespan.

How Long Should You Leave Juice in Your Vaporizer Tank?

It’s also important to note how long you should leave your juice in your vaporizer tank. Most tanks can hold around .25-.35ml of e-juice, so be sure to refill when necessary. If you don’t use your vape for a few days, the juice will start to evaporate and the flavor will begin to change. Once the juice has been exposed to air for too long, it can cause oxidation and create a sour taste.

To avoid these problems, make sure to keep an eye on your tank level and refill as needed. Vape juices typically last anywhere from 24-48 hours before starting to lose their flavor.

It’s not advised to leave e-juice in your tank for an extended length of time. If you keep unused e-liquid in your tank for up to 7 days, nothing will happen. But if you wait 14 days or longer, some terrible things may start to occur to your remaining vape juice [6].

What Happens When E-Liquid Goes Bad?

If you’ve ever left your vape juice in the sun or stored it somewhere warm, then smelled a rancid odor when taking off the top, that means oxidation has occurred. This is when the flavoring and nicotine dissolve into each other over time.

What Happens When E-Liquid Goes Bad?

When this happens to an e-liquid, it creates a gas called acrolein (the same chemical used in “smoke machines”) [7]. This gas is not only smelly, but it’s also toxic.

E-cigarettes are not 100% risk-free products; however, they are 95% safer than traditional cigarettes. If you want to avoid these harmful chemicals altogether, make sure to use fresh e-liquids every few weeks and store them at room temperature for maximum lifespan.

Is It Safe to Use Expired Vape Juice?

The answer to this question is a little tricky. Technically, it’s safe to vape expired e-liquid, but we don’t necessarily recommend it. The reason for this is that the flavor and nicotine may have diminished over time, causing you to smoke more in order to get the same effect. Additionally, that gas mentioned earlier (acrolein) becomes even more harmful when it’s oxidized.

So, if you can help it, try not to use expired vape juice – especially if it’s been sitting around for a while. If you do end up using an old liquid, just be prepared for a less pleasant experience overall.

FAQ

1. Can an expired vape juice hurt you?

No, it can’t. It may appear bland or underwhelming in flavor, but if the expiration date is exceeded by a few months, there is no risk. If the date has been out of reach for years, however, it’s not a good idea to eat it [8].

2. How long do vape liquids last once opened?

E-liquids are typically durable for up to two years if properly stored. The vacuum seal on the bottle is broken once you open it, allowing air to reach the e-juice. In 2-3 months, prepare to finish purchasing vape juice [9].

3. Is 2-year-old vape juice still good?

If you keep your vape juice in a cool, dark place and don’t open it for months at a time, then yes. Once opened though, the flavor may begin to fade over time.

4. Can I use old vape juice?

If you’re vaping solely for the nicotine, then it’s okay to use vape juice that is months or even years old. If you enjoy the taste of e-liquids though, try not to wait too long before replacing them.

5. How long does a 10ml bottle of vape juice last?

A 10ml bottle of vape juice is equivalent to 100 conventional cigarettes on average. So, if you smoked a pack of 20 cigarettes each day, a 10ml bottle should keep you smoke-free for around five days.

A 100ml container should last up to 50 days [10].

This question is difficult to answer because it depends on how often you vape and the nicotine strength of the juice. A general estimate would be one week, but it could last anywhere from a day to a month.

6. How long does vape juice last unopened?

When vape juice is not opened, it can last up to two years. However, when you open the bottle for the first time, use your e-liquid within six months. If you leave the vape juice out of its container, it will oxidize and change color. Through oxidation, e-liquid loses flavor and strength.

Once you open a bottle for the first time, use it within three months to avoid consuming flavors that have changed or lost their potency. You may even notice that your vape tastes burnt if you don’t use it up in time (burnt taste = oxidation). To prevent this from happening, store your vape juice away from heat and sunlight. This is why many manufacturers recommend storing bottles inside their original packaging until they are ready to be used.

7. Can I leave e-juice in my vape overnight?

No, you should never leave your vape juice in a tank overnight. Leaving e-liquid inside the wick of an atomizer or cartomizer can cause it to burn and ruin your device. E-juice is designed for use with specific vaporizers only. The oils found in some e-liquid may clog up an atomizer if used outside its intended purpose.

The bottom line is that you’re free to leave e-liquid in a tank for as long as you want. There may not be any issues at all. However, if you don’t want to chance it, try vaping with all of the e-juice in your tank the next time you put your e-cigarette away [11].

8. Does vape juice need to be shaken?

E-liquid can last for a long time without needing to be shaken. However, some oils will separate over time. This is why it’s recommended to shake your e-juice before each use.

Some people believe that shaking the e-liquid helps mix the ingredients and creates a more consistent flavor. Others think that shaking the bottle just redistributes the nicotine in the juice. No matter what the reason, it won’t hurt anything to shake up your vape juice before using it.

9. Why does the vape juice turn brown?

The color of vape juice can change over time for a few reasons. The most common reason is oxidation, which occurs when the e-liquid is exposed to air. This will cause the juice to darken and lose flavor.

Another reason for discoloration could be steeping. When nicotine absorbs into the vegetable glycerin or propylene glycol, it can turn brown over time.

If you’re not happy with the color of your juice, there are a few things that you can do:

  • Store your e-liquid in a cool, dark place;
  • Shake up the bottle before each use;
  • Remove as much air from the container as possible before sealing it shut;
  • Avoid exposing your juice to light or heat;
  • Steep your vape for between two weeks and a month;
