Heat, light, air, and moisture can all shorten their shelf life and strip away their natural aroma and effectiveness. The good news is that with the right storage methods, you can keep your oils pure and potent for years!
In this article, we’ll share simple yet effective tips to store essential oils properly, covering both general rules and oil-specific advice so that you can enjoy their full benefits in the long run.
What is the Durability of Essential Oils?
Essential oils are chemical compounds that are extracted from plants via distillation or pressing. Environmental conditions, extraction methods, and different plants all affect their chemical composition. Terpenes and phenylpropanoids are among the many constituents of these oils. Because of the interactions between molecules, every oil has distinct qualities.
Essential oils are volatile and reactive, therefore their quality may change based on the environment. Poor handling or storage might lead to property loss. Maintaining the right storage conditions—which include dark bottles, lower temps, and sealed containers—is crucial.
The shelf life will probably depend on the type of oil, but generally fits within one of these ranges:
- Citrus oils (lemon, orange, grapefruit) for one to two years,
- herb oils (peppermint, eucalyptus, tea tree) for two to three years,
- base note oils (patchouli, sandalwood, vetiver), six to ten years.
- carrier oils six months – two years (can go rancid).
Light, heat, oxygen, and moisture are the main things that will decrease shelf life.

Key Factors That Affect Shelf Life of Essential Oils
1. Light Exposure
Photodegradation occurs when essential oil is exposed to sunlight or strong lighting in the house. The potency decreases through the chemical process of degradation, and the oil’s color may change. Essential oils are usually sold in amber or cobalt glass bottles because this minimizes their exposure to UV rays.
2. Heat and Temperature
Like food sitting out in the sun, essential oils will “spoil” faster when exposed to heat. Heat will accelerate evaporation and breakdown of the oil’s composition. In an ideal world, essential oils would be kept at a temperature of between 15 and 25° C (59 and 77° F): a cool cupboard works!
3. Oxygen Exposure
Opening an essential oil container causes the oil to oxidize as it reacts with the oxygen in the surrounding air. They may become irritating to your skin and lose their medicinal properties the longer they oxidize! Always cap tightly, and consider putting essential oils into smaller bottles as they decrease, to avoid air space.
4. Moisture and Contamination
Water is a second consideration as it can introduce bacteria or cause hydrolysis. Just one drop (within the main bottle) of water can ruin the entire bottle. Always use clean and dry tools to handle oils. Do not open bottles in dank places, like bathrooms.

Check Out the Best Practices for Storing Essential Oils
- Use of Proper Containers
The container you choose is as critical as the decision of where to finally store your oils. Dark Glass Bottles: Amber and cobalt glass are ideal colors. They block UV rays and are non-reactive with oils.
- Stainless Steel: A good alternative for bulk storage, especially in industrial settings.
- Aluminum: Can work if it is lined for food-grade storage, but is less popular for home use.
- Plastic Is Out: Essential oils are highly concentrated and can break down plastic, causing leaks and contaminating the oils.
Additionally, opt for caps that form an airtight seal. Screw-on caps with liners, Euro droppers, or crimp caps for larger bottles work well.
- Cool, Dark Storage Locations
You can simply store all of the oils above in a closet, drawer, or container that is closed. For oils that may not last as long (citrus), you may want to store them in the refrigerator; however, you will need to let the oil come to room temperature before using it, as you do not want to make condensation inside the bottle.
- Minimizing Air Contact
Try not to leave essential oils open for long periods. A quick open-pour-close method is best. For frequent use, transfer a portion into a smaller “daily use” bottle so the main stock remains untouched.
- Proper Labeling
It’s easy to forget when you purchased or opened a bottle. Write the date of purchase and the date opened on each bottle. Following the “First In, First Out” (FIFO) method ensures you use older oils before newer ones.
Special Storage Tips by Oil Type
1. Citrus Oils
Because of their monoterpene content, oils that are high in oxidation (like lime) are best refrigerated to slow degradation. For any of your oils that come in a small airtight container or that you can transfer into a small airtight container, the less exposure to any air, the better.
2. Floral Oils
Certain oils – those with a high level of delicacy and light, such as rose, jasmine, neroli, etc. – are sensitive to both air and light. Use dark glass, store upright, and you can use natural antioxidants to lengthen the oil’s life.
3. Carrier Oils
Finally, carrier oils are different from essential oils; they are fatty oils that spoil more easily. The refrigerator is also the best place for storing carrier oils to inhibit spoilage. With carrier oils, like with essential oils, always check for spoilage before use, like any sour scent or discoloration.

How to know when essential oils have expired?
Despite having them in safe storage, oils will degrade over time. Signs of degradation include:
- Change in smell (foul, sour, or just worse than usual).
- A change in color (lighter or more cloudy).
- Changes in consistency (thicker or gummier).
- Irritating the skin, even on skin used previously with no reaction.
After identifying expired oils, do not just pour oils down the sink; oils can clog your pipes. Throw oil in the garbage (if it was just a small amount) or if it was a kilo of oil, you take the used oil to hazardous waste. Some expired oils can still be useful for cleaning surfaces, polishing wood, or using them in crafting.
Common Mistakes to Avoid
1. Organization Tips
Organize oils by type or purpose, maintain an inventory list, and rotate oils such that old oils are used first (first in first-in-first-out). You may use storage boxes, boxes with racks and shelving, to keep everything organized and accessible while minimizing exposure to light and air.
2. DIY Storage
Additionally, you may reuse items like muffin pans, spice racks, cardboard or wooden boxes, etc. These examples can all be excellent substitutes for storage. For further protection, you can use foam inserts or dividers.
3. Commercial Sources
For those who prefer a commercial option, cases made for carrying or storage, acrylic stand options, and wall cantilever racks are common. Many options are specifically designed for essential oils and will help you protect your collection while also making it easy to get to.
4. Flying with Essential Oils
Start by adhering to TSA’s 3-1-1 rule for carry-on items. In essence, you may take liquids in your carry-on that are under 3.4 oz each and must fit in resealable bags.
We recommend padded travel cases or roll-up organizers so you can avoid leaks and potentially get damaged by heat. For checked luggage, you will want to buffer the bottles well and consider insulated pouches in case of temperature fluctuations.

FAQs
- What is the best way to store essential oils?
Essential oils need to be stored in small amber or cobalt glass bottles with airtight lids to optimize their potential and shelf life. Essential oils should also be stored away from direct sunlight, heat and kept cool, dry, and dark. A drawer, secured cabinet, or even a special storage box will suffice. Refrigeration may also help when storing fragile oils.
- Are you aware of the fact that essential oils expire?
Yes, but not in the same way that foods spoil. The oils can lose some of their potency, aroma, and therapeutic benefits as time goes on; however, oxygen, light, and heat will speed up this process by changing the essential oil’s chemical makeup. Shelf life can vary for essential oils; some citrus oils will only last 1-2 years, while heavier oils like patchouli or sandalwood can last upwards of 8-10 years if stored properly.
- Should essential oils be refrigerated?
Refrigeration will delay the predicted life span of one or more oils, chiefly citrus oils, which degrade faster than others, but it is not necessary. If you choose to store the oil in a refrigerator, make sure to allow it to come to room temperature before using. Carrier oils can degrade over time, so it will not hurt anything to keep them in a cold environment.
- Are essential oils damaged by sunlight?
Direct sunlight is one of the natural enemies of essential oils. This is why essential oils are marketed in opaque glass bottles. When exposed to UV radiation, the chemical composition of essential oils breaks down quickly. This reduces light exposure and keeps the oil stable.
- Which temperature is ideal for storing essential oils?
The chilly, steady temperature range of 15–25°C (59–77°F) is good for essential oils. Keep them away from windows, stoves, heaters, and other places where the temperature fluctuates a lot. A cabinet or drawer is frequently the safest choice.
- Why are there bottles that are black instead of transparent?
Bottles made of cobalt or dark amber prevent oxidation. They also protect oils from harmful UV rays. Bottles constructed of plastic or clear glass can let light in. This, in turn, lowers the oil’s clarity and shortens its shelf life.
- For how long do essential oils last when properly stored?
Its shelf life is influenced by the variety of oils and storage circumstances.
As a bro Oils of citrus: 1-2 years
Two to three years for herbal oils like peppermint and eucalyptus
Base-note or woody oils (vetiver, sandalwood, and patchouli): 6–10 years
Oil carriers last anywhere from six months to two years.
These durations can occasionally be extended by using good storage procedures.
- Can essential oils be stored in plastic bottles?
No. Essential oils can break down plastic over time. Why? It is because of their high concentration, which might contaminate the oil or result in leaks. Hence, one must always use glass bottles, preferably amber or cobalt.
- Do certain oils have a longer shelf life than citrus oils?
Indeed. Compared to other oils, citrus oils are often more volatile. These are the same oils that are present in grapefruits, oranges, lemons, and limes. They oxidize considerably more quickly. These oils usually only last one to two years. However, a variety of essential oils may last three to five years. It is only if stored properly. They can also be kept in the refrigerator or in an airtight bag. By doing this, their shelf life will be extended.
