Can tea tree oil go bad?

In this short article, we will provide an answer to the question “Can tea tree oil go bad?” and the information on storing tea tree oil.

Can tea tree oil go bad?

Yes, tea tree oil can go bad but without causing harm to the user. Since essential oils do not contain any moisture that could cause them to expire, tea tree oil, like other essential oils, does not have an expiration date.

Tea tree oil, on the other hand, does not have an indefinite shelf life. Tea tree oil that has expired or gone bad has a different aroma and consistency than fresh tea tree oil, which are both indications that it has passed its expiration date.

How to Preserve the Safety of Tea Tree Oil?

It is believed that the high temperature is one of the primary reasons tea tree oil spoils more quickly than usual. Therefore, the best approach to ensure that it remains fresh for as long as possible is to store it in a cold, dark location.

You’ll also want to limit the amount of time it is exposed to the air. Because oxygen in the air is what causes the product to oxidize, the less air that the oil is exposed to, the less probable it is that the oil will oxidize. As a result, be cautious to properly close the bottle after each use and to avoid opening it unnecessarily. Always double-check that the lid is securely closed and that it is not broken or otherwise damaged.

Is it necessary to store tea tree oil in a refrigerator?

Even though tea tree oil does not require to be kept exceedingly cold, it can be stored in the refrigerator if desired. The oxidation and expiration processes will be slowed as a result of the chilly temperature and lack of light. Keep in mind that tea tree oil is quite potent and may harm other foods stored in the refrigerator. Other goods in the fridge may begin to smell and taste like tea tree oil, and food that has been exposed to it may begin to taste like tea tree oil (yuck).

When you remove the oil from the container, the shock of the lower temperature and the change in storage conditions may cause the oil to expire sooner than expected. Consequently, it’s best to store the oil in your extra “drink” refrigerator, if you have one, and only when you won’t be using it for an extended time. I recommend simply placing it in a medicine cabinet or cupboard where it will not be subjected to direct sunlight.

What Factors influence the shelf life of tea tree oil?

Factors that influence the shelf life of tea tree oil include:

  • The shelf life of all essential oils, including tea tree oil, is influenced by a variety of factors, including temperature and humidity. Because of how it is stored and used, the shelf life might be either shortened or prolonged. The most significant influence, however, is provided by appropriate storage.
  • The longer essential oils are exposed to air, the more oxidation occurs. This is an indication that the oil is degrading and losing its medicinal properties. However, there are strategies for preventing or decreasing the process of oxidation.
  • Keep the oil in an opaque or dark-colored container to avoid it from being exposed to sunlight, which will heat it and speed up the oxidation of the oil. The majority of oils are sold in amber glass bottles, which should be kept in a cool, dark place to prevent them from going bad. Indeed, the dark glass protects the oil from being exposed to light, which could cause the oil’s therapeutic characteristics to diminish over time.

How to detect spoiled tea tree oil?

As you might anticipate, the aroma of tea tree oil varies as the oil degrades. After a while, it starts to smell bad or harsh, or even medicinal rather than pleasant, like a tea tree.

There are other things to be careful of as well, in addition to the aroma. Also possible is a change in the texture of the oil, particularly close to the cap and at the top. As it oxidizes, it becomes thicker and stickier, making it more difficult to work with and apply. The oil that smells off is thick, or is sticky around the cap or neck of the container is most likely spoiled and should be discarded. Simply toss out the old bottle and replace it with a fresh one to complete the task.

What Happens If You Use Tea Tree Oil That Has Expired? 

In contrast to freshly extracted tea tree oil, expired tea tree oil will not provide any of the health benefits associated with fresh tea tree oil, and may even be harmful. Because of the bad smell and strange texture, it will be unpleasant to use for scent diffusing or disinfecting, and its anti-fungal properties will be diminished or altogether lost.
