Tea tree oil is one of the most popular essential oils on the market, and it’s easy to see why: It has a fresh, woodsy scent that can add an energizing boost to your favorite DIY beauty products.
But how long does tea tree oil last?
And more importantly, how do you know if your bottle has gone bad?
Here are some answers to common questions about this essential oil.
How Long Does It Take for Tea Tree Oil to Expire?
Tea tree oil can last up to three years if stored properly.
The shelf life of this essential oil depends on a few factors including how you store it and the type of tea tree used.
While there is no guarantee that your tea tree oil will last as long as it should, there are ways to extend its lifespan by keeping it in a cool, dark place and avoiding excessive heat or sunlight.
How Do You Know When Tea Tree Oil Goes Bad?
The best way to know whether or not your tea tree oil is still good to use is by checking its smell.
If it has gone rancid, you’ll smell a strong odor of sourness or vinegar.
Another sign that your tea tree oil may be bad is if it turns cloudy in color, even after shaking it thoroughly.
The same goes for losing its clarity and starting to look hazy or yellowish instead of clear; this can mean that your bottle has expired and the ingredients have separated from one another in the container.
Another indicator that your tea tree oil has gone bad is when it starts separating into layers inside the bottle:
You’ll see an oily layer floating above a watery solution at the bottom of the container—these two layers shouldn’t be mixed together!
Finally, if you notice stickiness after using some of your essential oils (like clogging up a sprayer), this could be another sign that they’ve lost their potency over time
How Do You Store Tea Tree Oil?
When it comes to storing your tea tree oil, there are a few things you need to keep in mind.
First and foremost, you should always keep your tea tree oil in a cool, dark place because heat will cause the oil’s potency to diminish over time.
You can store the bottle in any cabinet or closet as long as it’s out of reach of children who might mistake it for something edible (and yes, we’ve seen firsthand how fast kids can scarf down an entire bottle of household cleaner).
If space is limited, we recommend keeping your tea tree oil on the top shelf of your refrigerator so that it’s easy to access when needed and keeps out of harm’s way while also maintaining its effectiveness.
You’ll want to make sure that whatever storage container you use has an airtight seal—since tea tree oil is highly volatile and flammable at room temperature (not unlike gasoline), leaving even just one drop exposed can lead directly into disaster if not properly handled!
What Happens if You Use Expired Essential Oils?
As with any other product, expired essential oils can be harmful.
If you use them and your skin breaks out in a rash or you experience some kind of allergic reaction, the oil may not have been effective.
It’s also possible that the scent of your tea tree oil will be less potent than usual if it has expired.
In addition to any potential health risks associated with using expired products, there is also a chance that your essential oil won’t be as effective as it was before it expired.
This could happen because essential oils go bad after their shelf life has ended, which means that many of their properties have been lost during this time period—including those responsible for making them effective on certain types of ingredients!
This is why we recommend buying only small quantities at once–so you don’t end up wasting money on something ineffective (or worse yet…damaging).
Which Essential Oils Last the Longest?
There are many factors that influence the lifespan of an essential oil.
First and foremost, the type of oil plays a large role in how long it will retain its natural properties.
Aromatherapy uses essential oils derived from plants in their most concentrated form.
These can be applied directly to the skin or inhaled through steam or mist inhalation devices such as diffusers.
The bottom line is that tea tree oil doesn’t expire, but it does lose its potency over time.
If you’ve had a bottle of tea tree oil for over two years and aren’t sure if it’s still good or not, just give it a sniff!
You’ll notice right away if your oil has gone bad because it will smell rancid instead of fresh.
If this happens, throw out the old bottle and buy some new stuff from your local health food store or online retailer like Amazon.
