Your Guide to Storing Oils
Like any natural substance, essential oils go off over time. Storing your oils sensibly can increase their shelf life and keep them fresh.
Essential oils are sold in dark glass bottles. One reason for this is that they evaporate readily, if they are not sealed tightly you will need up with an empty container. The other very important reason is that the oils are easily damaged by bright light and exposure to high temperatures, which is why dark, not clear, glass is used.
Caring for your essential oils
Choose a dark, cool area to store for oils. You could even place them in the fridge, giving them their own shelf and ensuring they don’t freeze. Oils stored in the fridge may go cloudy, but this does not damage them and they will go clear again after an hour or two at room temperature, take them out at least an hour before you use them. Never store oils in bottles with rubber seals or pipette tips, as some oils react with the rubber and become unusable. Store your oils in a dark and cold place so that they will always be ready to use.
How long do essential oils last?
Theoretically, most types of essential oils should last for several years. You will find in practice however, that this is not always the case and that some of your oils will last for either a much longer or shorter time. Exceptions that you should make a note of when buying or blending your own oils include :
- Citrus oils – Apart form bergamot, all citrus oils begin to deteriorate after six months.
- Base oils – by contrast, some essential oils actually improve with age, especially sandalwood, patchouli and frankincense.
- Blends – You should store your blends in the same environment as the undiluted oils. You will still find that diluting the oil or oils reduces their effective life to about two months, however, after which the small fades and the active ingredients deteriorate.
How often you use a bottle of essential oil, thereby exposing it to oxygen in the air will also reduce its effective life. Apart from the oils mentioned here, a good rule of thumb to keep in mind for an oil’s best before date if between a year and 18 months. Once you have added an oil to a blend, it will only last for two months, so make small quantities at a time.
