Yes, soy wax can go bad. Like other natural products, soy wax candles have a shelf life.
Soy Wax Candle Shelf Life
According to the reference, soy candles typically last between 1 to 2 years unburned. This means that after this period, you may notice changes in the candle's appearance, scent, or performance.
Factors Affecting Soy Wax Shelf Life
While the general lifespan of an unburned soy candle is 1 to 2 years, various factors can influence how long it remains in good condition. These include:
- Storage conditions: Temperature and light exposure can accelerate the aging process.
- Ingredients used: Additives like essential oils can degrade over time and affect the scent.
- Manufacturing process: Some manufacturing methods might lead to less stable candles.
Identifying Expired Soy Wax Candles
Here are some signs that your soy wax candle might be past its prime:
- Changes in scent: The fragrance might become weaker or smell “off.”
- Discoloration: The wax might change color, indicating oxidation or aging.
- Poor burn quality: The candle might not burn evenly or produce a weak flame.
How to Extend Soy Wax Candle Life
To maximize the lifespan of your soy wax candles:
- Store in a cool, dark place: Avoid direct sunlight and temperature fluctuations.
- Keep them covered: Use a lid to prevent dust and debris from settling on the wax.
- Burn them within 1-2 years: This ensures the best fragrance and burn quality.
Other Natural Waxes
Other natural waxes, like coconut wax, also have a limited shelf life. The reference states that a coconut wax candle will burn at its best 1 to 2 years after purchase, similarly to soy wax.
| Wax Type | Shelf Life (Unburned) |
