Do essential oils expire?
Essential oils do not expire. They do not grow mold. They also do not grow mildew or even yeast. But that does not mean they will last forever. Why not? Oxidation—a chemical reaction where electrons are lost that can change the constituents of the oil. Oxygen, heat and light all contribute to oxidation.
To prevent oxidation and improve the shelf life of your essential oil collection:
- Recap your bottles tightly and quickly.
- Store in a cool place.
- Reduce light exposure and store oils in a dark colored bottle.
Check out our recommended shelf life chart below. Because our essential oils are bottled at a state of the art facility in the USA, it gives us confidence that the shelf life of your oil will not start until you open it for the first time. Watch for our new bottle labels that include the period after opening symbol for each different essential oil to help you identify the useful lifetime in months.
