Essential Oil Storage

Essential Oil Storage

It seems that just as there are many essential oils there are just as many opinions on how to store them properly. We will follow up with a few suggestions and observations we have picked up over the years but here is a quick list of some basic do’s and don’ts regarding storage for essential oils:


  1. Always store essential oils in dark colored glass. We chose cobalt blue bottles because it has great UV protection and it also looks nice!
  2. Always store bottles of essential oils away from direct sunlight and excessive heat to preserve the life of the oil.
  3. Always put the top back on when you are finished with the bottle to avoid oxidation.


  1. Never store a pure essential oil in a plastic bottle. At the very least you can have the plastic leach into the oil. In some cases like with Oregano essential oil, it will eat away at the bottle in a very short time
  2. Never store in a bottle that has a rubber dropper top. These are great for temporary caps while measuring you oils but can lead to everything from evaporation to the dropper top melting.
  3. Never let the oils go through heat/cool cycles. Consistently cool storage is beneficial for a longer life of a high quality essential oil.

Tips, Tricks and Myths

Now that we have the basics out of the way, there are a few things we have done over the years to help prolong the life of our essential oils:


The first being to store in the refrigerator if you have the room. This is especially true for citrus oils but is beneficial for all essential oils as well as carrier oils. This also eliminates any light from coming in contact with the oils during storage.

Reduce Oxidation

To avoid oxidation in larger bottles we like to transfer them to a smaller bottle once the original bottle is half full. One thing we also recommend to our clients is to purchase a smaller sized bottle of the oil they want, such as a 10ml or 15ml. This will not only give you an opportunity to try the oil out but also serves as a future bottle to transport your larger bottles into once they are partially used. All of our bottles are recyclable but it’s always better to reuse something when possible!

Clear Glass

There has been an ongoing debate about using clear glass to store essential oils. While we do not supply any of our oils in clear glass bottles it is not always a bad thing as long as it is done under a watchful eye. As we mentioned earlier, essential oils are best kept in a cool, dark environment. This can be easy to do once in your possession but the problem lies in the time it took the oil to get from production and in to your hands. Who knows how they were handled or stored before you received them?

Over the years I have seen countless instances of essential oils being sold in clear glass bottles. This is not necessarily a problem if the bottles were not out for display in direct light and in some instances they were even in a store front window! The only time I would suggest clear glass bottles is if you are making blends in your own home and can guarantee they will never be exposed to direct sunlight.

Relax and Enjoy!

If you are able to store your oils in glass bottles with no soft rubber, keep them out of sunlight and heat and make sure they do not get needlessly exposed to oxygen, you are on the right path to protecting your investment in essential oils!
