Do Essential Oils Expire?

Essential oils continue to gain popularity among people seeking alternative remedies to treat various health conditions. With the increased use of essential oils, many people wonder if these potent oils have an expiry date or if they last forever.

The shelf life of essential oils can vary depending on various factors such as the type of oil, quality, and storage conditions. Essential oils are extracted from plant materials, which means they are highly concentrated and volatile. These traits make them susceptible to degradation, oxidation, and deterioration.

It’s crucial to store essential oils in dark glass bottles, away from direct sunlight and heat, to extend their shelf life. But how long do they last before they lose their potency and effectiveness? In this article, we will dive into the shelf life of essential oils, how to determine if they have expired, and tips to make them last longer.

What are essential oils?


Essential oils are concentrated extracts of volatile aromatic compounds from plants, which are obtained through steam distillation or mechanical expression. They are highly fragrant and contain the natural essence of the plant in a powerful and concentrated form.


Essential oils have been used for thousands of years in various cultures for their therapeutic, medicinal, and cosmetic properties. They are commonly used in aromatherapy, massage therapy, skincare, cleaning products, and as natural remedies for a range of health conditions.


There are hundreds of different essential oils, each with their own unique chemical composition and therapeutic benefits. Some of the most popular essential oils include lavender, tea tree, peppermint, eucalyptus, and lemon. Each oil has its own specific uses and properties.


Although essential oils are natural and derived from plants, they are highly concentrated and potent, and should be used with caution. Some oils can be irritating to the skin or toxic if ingested. It is important to use essential oils safely and to always dilute them properly before use.

The shelf life of essential oils

Factors that affect the shelf life

The shelf life of essential oils can vary depending on several factors. The quality of the oil, storage conditions, and chemical composition all play a role in determining how long the oil will last. Essential oils that are pure and properly stored can last for several years, while oils that have been diluted or exposed to heat and light may expire much faster.

Typical shelf life of essential oils

The shelf life of essential oils can vary greatly depending on the specific oil. Some oils, like patchouli and sandalwood, can last for up to 8 years if stored under the proper conditions. Other oils, like citrus oils, have a shorter shelf life and may expire within a year. It’s important to note that even though an oil may be past its expiration date, it can still be used. However, it may not be as effective as a fresher oil.

Tip: Store your essential oils in a cool, dark place with airtight caps to maximize their shelf life.

Signs that an essential oil has expired

If you’re unsure whether an essential oil has expired, there are a few signs to look out for. A stale or rancid smell is a clear indicator that the oil is no longer effective. Similarly, if the oil has become cloudy or thick, it’s likely that it has passed its shelf life. Essential oils that have been exposed to air or light for too long may also lose their potency.

  • Cloudy or thick oil: If the oil appears cloudy or has thickened, it may be past its shelf life.
  • Off or rancid smell: If the oil smells stale or rancid, it may be expired.
  • Decreased potency: An expired oil may not be as effective as a fresh oil, even if it still smells fine.

Knowing the typical shelf life of essential oils can help you make informed decisions when purchasing and storing your oils. By keeping them stored properly and regularly checking for signs of expiration, you can ensure that your essential oils stay fresh and effective for as long as possible.

Factors that affect the shelf life

1. Quality of raw materials

The quality of the raw materials used to make essential oils affects their shelf life. High-quality raw materials contain less impurities and contaminants that can promote bacterial growth, which can lead to spoilage. To ensure that essential oils have a longer shelf life, choose products that are made from high-quality raw materials.

2. Storage conditions

Storage conditions play a significant role in the shelf life of essential oils. They should be stored in a cool, dry, and dark environment, away from direct sunlight and heat sources. Exposure to light and heat can cause essential oils to oxidize, which can lead to rancidity. Additionally, exposure to moisture or air can cause essential oils to degrade, leading to spoilage.

3. Chemical composition

The chemical composition of essential oils affects their shelf life. Essential oils that are high in monoterpene compounds are more susceptible to oxidation than those high in sesquiterpenes. Therefore, the composition of an essential oil affects its susceptibility to spoilage.

4. Age of the essential oil

Essential oils have a shelf life, and after a certain period, they start to degrade and lose their potency. The age of the essential oil affects its shelf life, and it is recommended to use essential oils within two years of purchase. Older essential oils have a higher risk of spoilage, and their therapeutic benefits may be less potent.

5. Contamination

Contamination is a significant factor that affects the shelf life of essential oils. When essential oils come into contact with bacteria or other contaminants, this can lead to spoilage. To prevent contamination, use clean and sterile containers when storing and handling essential oils. Additionally, avoid using oils that have been contaminated or show signs of spoilage, such as a foul odor or discoloration.

How to store essential oils properly

Keep them in a cool, dry place

Keep them in a cool, dry place

Essential oils are vulnerable to heat, light, and humidity. When storing your essential oils, you should keep them away from direct sunlight, moisture, and heat sources such as radiators or stoves. Ideally, store them in a cool, dry place like a medicine cabinet, drawer, or cupboard.

Use dark-colored glass bottles

Dark-colored glass bottles, especially amber or cobalt blue, help protect essential oils from light and UV rays. When essential oils are exposed to light, their chemical composition can break down, altering their potency and aroma. So it’s always best to store your essential oils in dark-colored glass bottles.

Label and date your essential oils

To help you keep track of the shelf-life of your essential oils, it’s important to label and date them. When you purchase a new essential oil, label it with the date it was purchased and the date you opened it. Essential oils have varying shelf-lives depending on their chemical composition, so make sure to do your research and know when to replace oils that have expired.

Avoid plastic containers

Plastic containers are not suitable for storing essential oils. Some essential oils, like citrus oils, can dissolve plastic, creating a hazardous situation. Also, plastics are often chemically reactive, which can lead to contamination of essential oils. Always choose glass or metal containers for storing your essential oils.

Keep them out of reach of children and pets

Essential oils are potent and contain high concentrations of active compounds, which can be harmful if ingested. Keep them out of reach of children and pets, and make sure to tightly seal the bottles after each use. If ingested, contact poison control immediately.

How to tell if an essential oil is expired

1. Check the expiration date

Most essential oils have a shelf life of 2-3 years from the date of production. Check the expiration date on the bottle to determine if the oil has expired.

2. Look for changes in color and scent

If the oil has gone bad, it may have a different color or scent than when you first bought it. For example, it may have a cloudy appearance or a strong unpleasant smell.

3. Test the oil on your skin

If you are unsure whether the oil has expired, you can test it on your skin to see if it causes any irritation or discomfort. If you experience any adverse reactions, the oil may have gone bad.

4. Store the oil properly

Proper storage can help extend the shelf life of your essential oils. Keep them in a cool, dry place away from direct sunlight and heat.

Remember to always follow the manufacturer’s instructions and guidelines when using essential oils. Expired oils may not have the same therapeutic benefits and could potentially cause harm if used on the skin.

Is it safe to use expired essential oils?

What happens to essential oils when they expire

Essential oils are highly concentrated plant extracts that have therapeutic benefits. However, like all natural products, essential oils have a limited shelf life. Over time, essential oils can oxidize, degrade, and lose their potency. As a result, they may not work as effectively and may even cause skin irritation or allergies.

When essential oils expire, their chemical profiles change, which can alter their therapeutic properties and safety levels. They may become rancid, opaque, or cloudy, they may develop a strong or foul odor, or they may lose their color and clarity.

Are expired essential oils safe to use

Using expired essential oils can be risky, even if they are diluted or used topically. Expired oils can cause skin irritation, allergic reactions, or even chemical burns. Additionally, essential oils that have expired may not have the same therapeutic benefits that they once had, meaning that you may not get the results that you are looking for.

Moreover, if you are using expired oils in a diffuser or inhaling them, you may be inhaling harmful chemicals that can cause respiratory problems or other health issues. Therefore, it is not recommended to use expired essential oils. It is better to dispose of them safely and replace them with fresh oils.

How to extend the shelf life of essential oils

  • Store essential oils in a cool, dry place away from direct sunlight and heat.
  • Avoid exposing essential oils to air or oxygen by keeping them tightly closed with their lids.
  • Do not store essential oils in plastic bottles or containers, as they can react with plastics and absorb the chemicals.
  • Label your essential oils with the date of purchase and the expiration date to keep track of their shelf life.

By following these tips, you can extend the shelf life of your essential oils and keep them fresh and potent for longer periods.

The benefits of using fresh essential oils

Preserving the potency of essential oils

Fresh essential oils are more potent and effective than ones that have expired or gone stale. When stored correctly, essential oils can last a few years, but they will eventually lose their potency and smell. Using fresh essential oils ensures that you are taking advantage of the full range of therapeutic benefits they offer.

Better aroma and flavor

Essential oils are used in many products, including perfumes, soaps, and culinary recipes. Using fresh essential oils will ensure that these products have a better and more genuine aroma than ones made with stale oils. Adding fresh essential oils to cooking can enhance the flavor of dishes and add a unique touch to a dish that is difficult to replicate with other ingredients.

Improved health benefits

Essential oils are known for their health benefits, including relieving stress and anxiety, reducing pain and inflammation, and improving skin health. Fresh essential oils have a higher concentration of active ingredients, which can improve their effectiveness. Using fresh essential oils in aromatherapy can also have a more profound impact on your mood and emotions.

Saving money and reducing waste

Using fresh essential oils can help you save money in the long run. When you use stale oils, you may need to use more of the product to achieve the desired effect, which can waste oils and money. Buying fresh oils in smaller quantities and using them before they expire can help save money and reduce waste. Additionally, using fresh oils reduces the likelihood of spoilage, which can result in having to throw out an entire bottle of oil.

In conclusion, using fresh essential oils provides many benefits, including better potency, aroma and flavor, improved health benefits, and cost savings. Make sure to store your oils properly and use them before they expire to take advantage of their full range of therapeutic benefits.

How to dispose of expired essential oils

1. Do not pour essential oils down the drain

It is important not to pour expired essential oils down the drain. This can harm the environment and contaminate water sources. Essential oils are highly concentrated and can damage pipes or even cause fires.

2. Donate or give away

If your expired essential oils are still relatively new and in good condition, consider donating them to a friend or family member who may be interested in using them. Alternatively, you could donate them to a local charity or aromatherapy group. Check with the organization first to see if they accept open bottles of essential oils.

3. Recycle the glass bottles

The glass bottles that essential oils come in can be recycled. Remove the label, rinse out the bottle and its cap, and recycle with your household glass. Some essential oil companies also offer bottle recycling programs, which you can take advantage of.

4. Dispose of through hazardous waste collection

If you have no options for donating, giving away, or recycling your expired essential oils, it may be necessary to dispose of them as hazardous waste. Check with your local waste management authority to see if they offer hazardous waste disposal services. Follow their instructions carefully to ensure safe disposal.

Essential oil alternatives to expired oils

1. Fresh essential oils

One of the best alternatives to expired essential oils is to use fresh ones. When you purchase a new bottle of essential oil, make sure to check the expiration date on the label. Keep the oil in a cool, dry place and use it within the recommended time frame.

2. Substitute with similar oils

If a specific essential oil has expired or is not available, there are plenty of substitute oils that can be used. For example, if your expired peppermint oil is no longer effective, you can try substituting it with eucalyptus oil which has similar properties.

3. Essential oils blends

Another alternative to expired oils is to create your own essential oil blends. Mixing different oils together can create a unique aroma and therapeutic properties. You can experiment with different combinations until you find the perfect blend that suits your preferences.

4. Natural alternatives

If you don’t have access to fresh or substitute essential oils, you can also try using natural alternatives. For example, lavender flowers or chamomile can be used as a natural substitute for lavender essential oil. You can make a homemade infusion with these natural products to create a similar aroma and effect as the essential oil.

5. Aromatherapy diffuser

If you don’t have any essential oils on hand or want to try a different approach, an aromatherapy diffuser can also be used. Simply add water and a few drops of your preferred natural oil such as lemon or peppermint, and let the diffuser spread the aroma throughout your home.
