6 Tips to store essential oils last longer at home
Make sure your oils are stored in dark-colored glass bottles. Please notes that the amber glass bottles are standard, adding “dark-colored glass bottles are preferred as they provide protection against ultraviolet light.”
Store your oils in dark glass bottles. Exposure to light can cause essential oils to oxidize rather quickly. As this happens, they typically lose their fragrance and any therapeutic qualities they may have had. Because of this, clear glass and plastic bottles should be avoided at all costs.
Amber and cobalt-blue glass bottles are fairly common. Green and violet glass is also somewhat common.
These dark glasses will help reduce the risk of oxidation, but they will not eliminate that risk.
Plastic, no matter what color it is, should generally be avoided. PET and HDPE plastics will not deteriorate from oil storage, but most other plastics are easily broken down by oil.
2. Make sure the caps are airtight. Exposure to air can cause oils to oxidize just as much as exposure to sunlight. Because of this, it’s important to ensure that your bottles have an airtight seal. Most screw-on caps will have a good seal, but any bottle that uses decorative plug-in stoppers should be checked to make sure air cannot get in and oil cannot get out.
3. Storing Oils in a Stable Environment
Definitely don’t keep them anywhere with sunlight or moisture. it accelerates the oxidation process including bathroom or bedroom shelves. Sunlight can cause oils to oxidize in just a few months. You can store them in a closet or inside a drawer, though there’s no way to regulate the temperature in a storage spot like this. The best place to store essential oil is in a cool, dry place with a well-regulated temperature.
4. Because a little goes a long way, oils will last a long time. As such, it’s better to use smaller glass bottles to store them (15 ml or smaller). Less oil in the bottle means less oil that could potentially be wasted. Remember to always tightly close the bottle after each use.
5. It’s worthwhile to limit the time the cap is off the bottle at all. The less oxygen, the better. Use solid screw caps instead of rubber bulb-capped lids. Many oil bottles come with a rubber bulb built into the cap. This is to facilitate easier application of the oils inside. These lids may be convenient, but the rubber will deteriorate over time. Even after a relatively short period of storage, the rubber inside the bulb can disintegrate and may even leak down into your oil.
6. Don’t remove the plastic orifice reducer over the mouth of the bottle. It helps the oil flow one drop at a time—but also limits the amount of air that gets into the bottle.
