Essential oils are powerful tools for a wide range of purposes, from stress relief to pain management. They are also highly concentrated, and their active compounds can deteriorate over time. This can cause the oil to lose its potency and make it less effective in your cleaning routine. In addition, using an expired essential oil could be dangerous to your health.
The shelf life of essential oils depends on a variety of factors, such as temperature, light, and oxygen. When the oil is exposed to heat or light, it can accelerate the oxidation process and shorten its shelf life. Storing the oil in a dark, cool place can extend its shelf life. Essential oils can also be stored in the refrigerator, which is especially helpful for citrus oils that tend to oxidize quickly.
When deciding whether an essential oil is still good, keep in mind that it may not look as appealing or smell as fresh as it did when you first purchased it. The color of the oil can change as it ages, and you may notice that the aroma has changed as well. However, an essential oil that has not been used or abused can be safe to use for as long as it hasn’t changed color or smells bad.
How long an essential oil lasts will depend on the oil’s chemical makeup and distillation methods. Oils with high levels of monoterpenes will oxidize within one to two years, while oils that contain mainly sesquiterpenols can last up to twenty years. Oils that are steam distilled will have longer shelf lives than those that are cold-pressed or solvent extracted.
While the shelf life of essential oils varies, most will last for up to five years when properly stored. This includes storing the oils in a dark, cool place and not leaving the cap off for extended periods of time. It is also important to note that certain oils, like cinnamon bark and peppermint, contain phenols that are toxic when ingested in large amounts. Expired peppermint or cinnamon bark oil could have higher concentrations of these compounds than what is considered safe to consume.
The best way to keep your essential oil shelf clean and organized is to invest in a dedicated shelf or cabinet that will be specifically designed for storing essential oils. This will protect the oils from sunlight, heat, and moisture, which can all affect their shelf life. A solid wood shelf is an excellent choice because it will last longer than a cheaper, plastic storage unit. To build a simple wooden essential oil shelf, start by measuring your space and cutting the boards to size. Then, nail them together and screw in the Perfect Hang hooks to hold the oil bottles. Once the shelf is complete, find a good spot to hang it and enjoy your new essential oil storage!
