Have you ever purchased a candle so amazing that even the thought of burning it causes you pain? We have some good news and bad news for you. Fact is, candles can in fact expire, however they won’t expire in the fact that they spoil like we are used to in food items. They will simply lose their potency and fragrance when they are smelled or finally lit.
So what determines the length of time it takes for a candle to expires? There are many factors.
Wax Used
The type of wax used is probably the main determining factor in how long your candle is expected to last. Paraffin wax for example can last almost indefinitely considering it is made out of a plastic like substance.
Soy wax (which is what we use of our candles) are best burned within 1 year of purchase because it is a natural ingredient. (Read more on why we use Soy wax from our Blog Post).
Type of Fragrance
The type of actual fragrance used is another big factor in how long your candle will hold its fragrance potency. Artificial fragrances will tend to last longer since they are made of blends and multiple ingredients. Natural fragrances blended in oils will have a shorter fragrance time frame because it’s a natural ingredient.
Natural ingredients do tend to be more fragrant and potent though, so even if they do start losing their scent, it will take longer for the candle to lose it’s scent entirely.
Dye
Dyes used in candles come in a wide variety of strengths, shades and tints. That said, over time a candle’s color may fade as well. Typically, a candle that is left in sunlight or with its lid off will start to fade sooner.
How to extend a candle’s lifespan:
- Keep candles in a cool dark place if not planning on lighting for an extended period of time.
- Keep out of direct sunlight
- Use a candle topper or seal with it’s own lid
- Avoid storing in places with high humidity or moisture
- Avoid areas that have consistent temperature changes
