Candles can expire and go bad, although not in the same way that food expires. There are several things to consider when buying a candle, especially how long it has a shelf life.
Two common ways that candles can expire or go bad are fading and diminishing odor. Some candle waxes hold their color longer than others, while some scents stay fresh longer than others. You must know what ingredients are in a candle to determine how long it has a shelf life.
Some of the factors that cause candles to deteriorate include UV rays, ambient temperature, storage methods, any chemical additives, type of scent and fragrance, and type of wax. There is no danger in lighting old candles, but these different factors may affect how long the candle burns and how it smells.
Although candle wax does not expire, it does deteriorate and weaken. If Colored Candles are left on a windowsill, UV light will break down the colorant and the candle will fade. Heat will also break down the scent of the candle.
Paraffin wax is a petroleum-based wax and therefore has a long shelf life. A conservative estimate is five years, but many paraffin wax candles last much longer. If the candle has color and fragrance, both of these properties will fade over time. Most candle scents are best burned no later than one year after purchase. Store candles in an airtight container in a cool, dry place. Avoid direct sunlight to prevent color fading.
Beeswax is a natural wax that has the longest shelf life of any candle. In fact, it is believed that beeswax candles will last indefinitely. Many people believe that beeswax candles never expire, which suggests that the Egyptians used honey. Sometimes the Egyptians used honey as an embalming fluid and sealed sarcophagi with beeswax. It is true that honey does not spoil, but in order for your beeswax candles to look like new, you need to store them properly in 100% cotton or paper towels. Make sure to store your candles out of direct sunlight.
Soy wax is an organic material made from soybeans. Just as soybeans can spoil and rot, soy wax can also spoil. While you can use various additives to extend the life of soy candles, if the candle is scented, the scent may counteract the additives. Chemical reactions, especially over time, may even accelerate the deterioration and breakdown of soy candles. Soy candles typically have a shelf life of 1-2 years. Many soy candles are jarred candles. If your candle has a lid, seal it before you are ready to burn it to ensure you get the best possible throw and burn time.
Due to UV deterioration, heat and chemical reactions of the candle components, candles may deteriorate when the color and scent disappear. When you know the length of time different candle waxes retain these properties, you can choose a candle based on its expected shelf life.
