Candles have long been cherished for their ability to add ambience, fragrance, and warmth to any setting. Whether you’re lighting a candle to relax after a long day, to celebrate a special occasion, or simply to enjoy its scent, you might wonder about the longevity of your candles. At Highland Candle Company, we understand the importance of quality and longevity in our candles, and we’re here to share everything you need to know about candle expiration and how to maximize the lifespan of your candles. So, do candles expire?…
The Essence of Candle Longevity
Candles do not expire in the traditional sense, like food products, but they do undergo changes over time that can affect their performance and fragrance. The shelf life of a candle primarily depends on its wax composition, fragrance oils, and storage conditions.
Wax Composition and Candle Longevity
- Paraffin Wax: Derived from petroleum, paraffin wax candles are known for their long shelf life, often lasting up to five years if stored properly. However, fragrance retention might begin to diminish after two years.
- Soy, Beeswax, and Coconut Oil Waxes: Natural wax candles, made from soy, beeswax, or coconut oil, may start to show signs of rancidity due to the natural oils they contain. These candles are best used within the first two years to ensure optimal burn quality and fragrance.
Fragrance Fading Over Time
Fragrance oils, whether synthetic or natural, will gradually weaken over time. This process is influenced by the quality of the fragrance oil, the type of wax, and storage conditions. To preserve the scent, store your candles in a cool, dark, and dry place away from direct sunlight and extreme temperatures.
Candle Storage: Maximizing Longevity
Proper storage is crucial for maintaining the quality and extending the life of your candles:
- Avoid Direct Sunlight: Store your candles away from windows or areas where they’re exposed to sunlight, which can cause the wax to melt or fade.
- Keep in Cool, Dry Places: Moisture can affect the wick, making it difficult to light, while heat can cause the wax to soften or melt.
- Use Air-Tight Containers: For natural wax candles, storing them in air-tight containers can help preserve their fragrance.
Signs of Candle Aging
While candles may not “expire” in the conventional sense, there are indicators that a candle is past its prime:
- Fading Fragrance: If the scent is noticeably weaker or has altered, the candle’s fragrance oils may have degraded.
- Discoloration: Changes in the wax colour can indicate exposure to light or ageing.
- Difficulty Lighting: If the wick is hard to light or the candle burns poorly, it may be time to replace it.
FAQs on Candle Care and Longevity
Can Expired Candles Be Harmful?
While using an older candle isn’t usually dangerous, it’s essential to ensure that the candle burns correctly. An improperly burning candle can release soot or potentially harmful substances, especially if the wax or fragrance oils have degraded significantly.
How Can I Tell if My Candle Is Too Old?
If your candle shows signs of significant discolouration, has a weak or altered scent, or doesn’t burn properly, it may be best to replace it. Trust your senses—if something seems off, it likely is.
Do Unopened Candles Last Longer?
Unopened candles, especially those stored under ideal conditions, can maintain their quality for longer periods. However, natural wax candles and those with essential oil fragrances are still susceptible to the natural degradation process.
