Candles do not have a hard expiration date, but they do degrade over time. The rate of degradation depends on the type of wax and how the candle is stored. Natural waxes like soy and coconut have a shelf life of about one to two years and are more prone to breaking down over time. On the other hand, paraffin and beeswax candles are more stable and can last almost indefinitely if stored correctly. The fragrance of a candle is often the first thing to degrade, and candles stored in direct sunlight or high humidity may also experience colour fading.

| Expiry | Candles do expire, but they do not have a hard expiration date. |
| Lifespan | Paraffin and beeswax candles can last almost indefinitely if stored correctly. Soy and coconut candles typically last between 1 to 2 years unburned. |
| Factors Affecting Lifespan | The type of wax and how the candle is stored are the main factors determining a candle's lifespan. |
| Degradation | Scent degradation is the first type of degradation that occurs in a candle. The fragrance weakens with age, and the colour may fade or change. |
| Burning Expired Candles | Expired candles may burn less evenly and may have a weaker fragrance. They may also be more difficult to light due to wick clogging. |

What You'll Learn
Beeswax candles don't expire
While opinions vary on whether candles expire or not, beeswax candles are unique. Unlike candles made from other types of wax, beeswax candles do not expire. They can be stored for long periods of time without degradation. Beeswax candles have been found in sunken ships several hundred years old and have burned beautifully after the wicks were dried out.
Beeswax candles are favoured for their longevity and are often included in emergency kits. They do not go rancid and are not affected by factors like fragrance load or colourants, which can cause other candles to expire. Beeswax candles may ''bloom' over time, but this is considered a good sign, indicating that the candle is made of pure beeswax. Blooming can give the candle a frosted appearance, which is desirable to some people. If you prefer a shinier look, you can simply polish the candle with a soft cloth.
To ensure the longevity of your beeswax candle, proper storage is essential. It is recommended to wrap the candle well, preferably with paper, cotton, or newspaper sheets, and store it in a cool, dry place away from direct light.
While beeswax candles themselves do not expire, their wicks can dry out over time. Therefore, it is crucial to keep the wick intact to ensure the candle can be burned effectively.
In summary, beeswax candles are known for their durability and indefinite shelf life. With proper care and storage, they can be enjoyed for generations without worrying about expiration or degradation.

Paraffin candles can last indefinitely
The lifespan of a candle depends on its composition and storage conditions. While candles made from natural or organic waxes like soy and coconut have a shorter shelf life, paraffin candles can last indefinitely under the right circumstances.
Paraffin wax is a low-grade petroleum wax commonly found in inexpensive candles. It is highly stable and does not require preservatives, making it suitable for long-term storage. When stored properly, paraffin candles can maintain their integrity and burning capabilities indefinitely.
To ensure the longevity of paraffin candles, proper storage is essential. It is recommended to keep them away from direct sunlight and harsh lighting conditions. Using a candle topper or a glass cloche can help preserve the fragrance and protect the wax from dust and debris. Additionally, storing candles in a dark, cool, and dry environment is crucial. Areas with high humidity, moisture, or sudden temperature changes should be avoided.
While paraffin candles can last indefinitely, their scent may degrade over time. This is due to the gradual evaporation of fragrance oil molecules from the wax, even when the candle is unlit. However, this process occurs slowly and may not be noticeable for the first six months to a year, depending on the quality of the fragrance oils used.
In summary, paraffin candles have the potential to last indefinitely when stored correctly. Proper storage includes protecting them from light, temperature fluctuations, and humidity, which can impact the integrity of the wax and fragrance. While the candle's scent may fade, its burning capabilities can remain intact for an extended period with proper care.

Scented candles lose fragrance
Scented candles do lose their fragrance over time, but they do not spoil like food or drinks. The lifespan of a candle depends on several factors, including the type of wax, the type of fragrance, the fragrance load, age, and storage conditions. Beeswax candles, for example, are known to have a very long shelf life and do not expire, which is why they are often chosen for emergency kits. Commercial-grade candles also contain preservatives to prevent the wax from deteriorating and changing colour.
The fragrance in candles can degrade and dissipate over time, especially if the candle is not stored correctly. Proper candle storage involves keeping it in a cool, dry place, away from direct sunlight, and ensuring it has a lid to protect it from dust and other contaminants. With proper storage, a candle can last for more than a year before losing its scent.
To get the most out of a scented candle, it is recommended to burn it for around three to four hours at a time. This allows the wax to melt evenly and creates a strong fragrance throw. Burning for too long can cause the wax to overheat and become too thin, while burning for too short a time can result in tunnelling.
Additionally, it is worth noting that our perception of a candle's scent can change over time due to a phenomenon known as "nose blindness". This occurs when we are exposed to the same scent for an extended period, causing it to become less noticeable. To counteract this, it is recommended to switch between different scented candles to keep the fragrances fresh and noticeable.
Overall, while scented candles do lose their fragrance over time, proper storage, usage, and rotation can help extend their lifespan and ensure a pleasant fragrance experience.

Soy candles expire in 1-2 years
Candles can expire, and the lifespan of a candle depends on its ingredients and how it's stored. While paraffin candles can last almost indefinitely when stored properly, soy candles are best used within 1-2 years.
Soy candles are made from organic, vegetable-based wax, which is more prone to breaking down over time. The quality of the wax and the way it's processed are key factors in determining the lifespan of a soy candle. When soy wax starts to degrade, the wick may become clogged, and the candle will be difficult to light.
To extend the lifespan of a soy candle, it's important to store it properly. Keep candles away from direct sunlight and other harsh lights, and store them somewhere dark, cool, and dry. Avoid areas with high humidity or moisture, such as bathrooms, and areas with sudden changes in temperature, such as radiators or vents.
In addition to proper storage, the way you burn your soy candle can also impact its lifespan. When lighting your soy candle for the first time, let the wax melt all the way across the surface before extinguishing it. This helps prevent tunneling issues. Also, make sure to trim the wick to about a quarter of an inch above the wax before lighting it. If the wick is too long, the flame will be too hot, which can lead to an uneven burn and negatively impact the candle's lifespan.
By following these simple storage and usage tips, you can help your soy candles maintain their quality and fragrance for up to 1-2 years.

Coconut candles expire in 1-2 years
Candles are a great way to add a touch of ambiance and elegance to any room. But, like any other product, they too have a lifespan and can expire. Coconut candles, in particular, are made from organic, vegetable-based wax, which is more prone to breaking down over time. While they may not decompose, coconut candles will typically last between 1 to 2 years if left unburned. After this time, the wick may become clogged, making it difficult to light the candle.
There are a few signs to look out for that indicate your coconut candle is past its prime. Firstly, check the scent. Scented candles will eventually lose their fragrance, and any unpleasant or unnatural odours are a warning sign that your candle is nearing the end of its life. The colour of the candle may also start to fade, and you may notice a change in the consistency of the wax.
To extend the lifespan of your coconut candle, proper storage is key. Keep your candle in a cool, dry place, away from direct sunlight and other harsh lights. Sunlight can cause the wax to fade and weaken, and can even make the candle decay faster. If you can, store your candle in an airtight container or a sealed bag to keep it fresh for longer.
Additionally, when burning your coconut candle, ensure you follow the correct safety procedures. Allow the candle to burn until there is a protective layer of wax underneath, as this helps to retain its scent and protect the unburned wax. Always keep the candle away from open windows, as a breeze can blow the wax out of place and hinder its burning experience.
By following these simple tips, you can maximise the lifespan of your coconut candle and enjoy its luxurious burning experience for up to 2 years.
