Do the candles have an expiration date?

Scented candles, like other products, can lose their properties over time - but do they have a specific expiration date? Here's everything you need to know about the durability of candles and their proper storage.
Can a candle get "overdue"?
The candles do not have a formal expiration date, but their ingredients - particularly the fragrance oils and natural waxes - may lose their intensity over time. This means that after a few years the scent may be less noticeable and the candle burns less evenly.
What does the durability of a candle depend on?
- Type of wax - Natural waxes (soy, palm, coconut) are more prone to oxidation than paraffin.
- Fragrance composition - Essential oils are less durable than synthetic compositions.
- Storage method - Exposure to light, heat and moisture can deteriorate the quality of the candle.
How to store candles to keep their quality for as long as possible?
- Store the candles in a cool and dry place, away from direct sunlight.
- Close the lids, if the candle has them - you will reduce the oxidation of the fragrance.
- Avoid extremes of temperature - both frost and heat.
How to recognize that a candle has lost quality?
- Weaker or no smell when smoking
- Altered wax consistency
- Difficulties with even firing
- Discoloration on the surface of the wax (note! natural waxes, such as soy wax, may have discoloration and non-uniform coloration-this is natural with them).
This does not mean that such a candle is harmful - but it may no longer give as pleasant an experience as a newer one.
FAQ - frequently asked questions about the expiration date of candles
Can I burn an old candle?
Yes, if it looks good and the wick lights up - you can light it safely. The fragrance may be weaker, but the candle will still do its job.
Can a candle go bad?
Not in the biological sense, but it may dry out, lose its smell or discolor.
How many years can a candle stand?
A well-stored candle can retain its properties for up to 2-3 years. However, the best results come from using within the first year.
