If you are a fan of reed diffusers for creating a calming, fragrant atmosphere in your home, you know how quickly the lovely aroma can fade. But did you know that how you store your aromatic oil plays a huge role in maintaining its freshness and potency? 

Many people unknowingly shorten the lifespan of their favorite diffuser oils by exposing them to the wrong conditions. Light, heat, and even storage containers can impact the longevity of your oils. Thus, it's important to know how to keep your oil fresh as long as possible. In this blog, you will learn how to prevent reed diffuser oil from losing scent, where it should be kept, and where not to keep it for your favorite oil to last longer.

Why Proper Storage Matters?

  • Aromatic diffuser oils contain delicate fragrance compounds that can break down over time. 
  • Factors like heat, light, fluctuating temperatures, and air exposure cause the scent to weaken. 
  • By following simple steps, you can keep your diffuser oil fresh, aromatic, and effective for months.

1. Keep Them Away From Direct Sunlight


One of the easiest ways to prevent the freshness of your diffuser oils is by protecting them from direct sunlight. Light, especially UV rays, can break down the natural compounds in the oil, causing the fragrance to fade faster.

2. Store Them in a Cool Place

Heat can also damage the quality of your diffuser oils. Like most essential oils, extreme heat causes the oil to lose its aroma and even degrade the oil itself. Aim for a cool room temperature, typically between 15-24 degrees Celsius. 

Avoid areas that experience significant temperature fluctuations, such as near radiators, heaters, or air conditioners. This can cause the oil to break down more quickly. The kitchen is often the warmest room in the house, so try to keep your diffuser oils away from cooking areas where they could be exposed to heat.

3. Choose Glass Bottles for Storage


If you store a larger supply of diffuser oil, make sure to keep them in glass containers rather than plastic bottles. Glass is non-reactive and does not react with oils the way plastic do. Plastics leaches chemicals over time when exposed to concentrated oils for extended period, which affect the quality and scent of the fragrance.

Ideally, use dark-colored glass bottles–amber or cobalt blue glass bottles are best, as they offer the best protection from light, helping to preserve the freshness of the oil. So, if your oils are in a clear bottle, consider transferring them to a dark glass bottle for better storage.

4. Tightly Seal the Bottle


Just like when you open the bottle of your favorite perfume, the scent of diffuser oils can begin to fade when it's left open to air for too long. Oxygen causes the oil to oxidize which weakens its scent over time.

To keep your oils as fresh as possible, always seal the bottle tightly. If you have a diffuser bottle that doesn't have a secure cap, you can transfer the oil to a different container with a tighter seal. Also, when not in use, always keep the cap on the oil bottle to minimize exposure to air.

5. Avoid Storing Near Strong-Smelling Products


Essential oils and fragrance oils are sensitive to other scents, and storing them near strong-smelling products can cause them to absorb other odors. For ex- if you place your oils next to cleaning products, perfumes, or heavily scented items can change the scent profile of your aromatic oils. Think of a smell-neutral place—away from anything that coild over power or alter the natural aromas.

6. Transfer to a Smaller Bottle When Running Low


When you notice your diffuser oils bottle is running low, it is a good idea to transfer the remaining oil to a smaller glass bottle. This is because, when there is a lot of air in the large bottle, the increased exposure to Oxygen leads to oxidation, weakening your oil’s fragrance over time.

Transfer of the oil to a smaller bottle minimizes the amount of air in the container, reducing the chances of oxidation, and preserving the oil’s freshness.

7. Use the Oils within the Recommended Time Frame


Even with the best storage practices, reed diffuser oils do have their shelf life. Over time, oils can lose their fragrance and become less effective. Most high-quality oils have a shelf life of about 6-12 months, depending on the ingredients. So it's recommended to use the oils within the estimated time frame. 

Quick Freshness Test: If you are unsure whether to use it or not, smell the oil before refilling your diffuser to make sure it still has the intended scent.

Can Diffuser Oils Be Stored in a Refrigerator?


Most people think of storing the diffuser oil in the refrigerator to provide cool, light-free environment. However, it is not recommended. While refrigeration can slow down the oxidation process and preserve the freshness of many substances, the same is not applicable to the aromatic oils.

Here are the 3 reasons why you should avoid refrigeration:


1. Consistency Issues


Many diffuser oils, especially those based on essential oils or synthetic fragrance oils, can change their consistency when refrigerated. They might become viscous or even solidify slightly which can then affect the oil absorption by the reeds. Thickened oil can clog the reeds or slow down the dispersion process.


2. Moisture Exposure


Refrigeration can have varying levels of humidity and exposure to moisture content negatively effects the quality of the oils. This can also lead to mould growth in the oil affecting freshness.


3. Temperature Fluctuations


Every time you open the refrigerator the temperature fluctuates which can cause condensation or alter the chemical balance of the oils.


Exception: If you live in a very hot environment and the oils are at risk of becoming too volatile or evaporatoing too quickly. You can consider storing them in the refrigerator for shorter periods.

How to Store Reed Diffuser Oil


To keep the diffuser oil fresh, it's better to store it in a cool, dark place as discussed earlier. 

  • In a cool, dark cupboard or drawer away from the heat & direct sunlight 
  • A shaded shelf away from strong-smelling items


These places are ideal to maintain the oil viscosity and fragrance without potential damage in consistency or exposure to moisture.
