What Affects the Shelf Life of Essential Oils?
Heat and light can damage essential oils. It is also important to remember that they are flammable, and each has its own temperature at which it may ignite. Make sure to store your essential oils away from any heat sources like the oven or stovetop and make sure they are kept at room temperature.
Never place them in direct sunlight either because doing so can affect the color and properties of the essential oil. In the same respect, oxygen and moisture should also be kept away because these elements can end up evaporating the essential oil. If you are unsure if any oxygen or moisture was introduced to your bottle of essential oil, check for any cloudiness and see if you can spot any beads of water at the bottom of the container.
If you found that your essential oils were affected, you may still be able to use in some cleaning product DIYs or even in your diffuser.
Choose the Right Container
Essential oils should be in an amber or cobalt glass bottle. The darker color helps keep light out and maintains the integrity of your oil. Never store the oil in a plastic container of any kind because essential oils are corrosive and will eat through the plastic. You should only use glass containers.
Always store the essential oils with their lids tightly in place to help avoid any danger of oxidation and moisture.
Shelf Life for Essential Oils
As already mentioned, when you properly store your essential oils as we suggested, you can extend their shelf life much longer. For example, a lot of citrus essential oils have a shelf life of between one and two years. Most other essential oils have a shelf life of four to eight years while oils from the wood and root family can last a decade or more when properly kept and stored.
Some essential oils even increase in their potency as time goes on. An example of this would be patchouli and sandalwood. So not only are you extending their shelf life, but you are also effectively increasing the oil’s potency.
Meta: When properly kept and stored, your essential oil collection can last you for several years, if not longer than that.
