1. Can you keep essential oils in the fridge?
Some essential oil lovers swear by putting their oils in the fridge. It isn’t so much the lower temperature that matters—oils do not need to be kept that cold—but the consistent climate. Your fridge stays the same temperature day and night, which helps preserve the oil. If you don’t want your oil to be cold when you use it, be sure to remove it about 1–2 hours before you’ll need it so the oil can return to room temperature. Once you’re finished using the oil, put it back in the fridge so it can return to a consistent temperature.
2. Is it okay to freeze essential oils?
Putting essential oils in the freezer is perfectly safe. The consistent temperature and lack of light will help to preserve your oils. There are some oils—like Rose, Thyme, and others—that may have natural components that solidify or crystallize in the freezer. If your oils do this, simply allow them to thaw before you use them by keeping them at room temperature. Once you’re finished with them, return them to your freezer to store.
