How and Where to Store Essential Oils
For the storage of essential oils, they should be kept in the dark-colored (usually amber or cobalt blue) glass bottles that you buy them in (see Buying Essential Oils). Store all essential oils in a cool, dry, dark place. Keeping them tucked away in a covered box or cabinet where they are in the dark and out of direct sunlight is highly recommended; just use caution to be certain they are stored out of reach of children and animals.
Make sure that the lids are always on tightly; cover immediately after use. Note that essential oils are flammable, so care must be taken.
As a general rule, essential oils when stored properly have a shelf life of about two years. Citrus oils, such as lime, sweet orange, grapefruit, and lemon, are exceptions as they have a shelf life of about six months. An expiration date included on the bottle, if there is one, can be your guide.
