Many people wonder why their candles, which smell great when unlit, don’t emit a strong fragrance when burned. Today, I’ll explain why your aromatherapy candle might not be as fragrant as expected.
The diffusion of aromatherapy candles is influenced by various factors. Internally, it’s related to the candle’s manufacturing and materials, while externally, it’s about how you use it.
Internal Factors:
- Incorrect Oil Ratio: The most common reason for poor diffusion is an incorrect oil ratio. Both manufacturers and original brands can make this mistake. A recommended oil ratio is around 5%-10% of the total net weight of the finished candle. Some manufacturers may use a lower ratio for cost or preference for milder scents, which can result in poor diffusion.
- Inappropriate Wick: Most aromatherapy candles on the market use cotton wicks or a combination of wick materials, with some featuring wooden wicks. The size of the wick and the candle container’s diameter-to-wick-size ratio can impact diffusion. If the wick is too small, it won’t generate enough heat to vaporize the essential oils into the air. If it’s too large, it can produce excessive heat, causing the oils to burn before diffusing properly, resulting in an unusual scent, sometimes resembling a burnt odor.
- Incorrect Oil Type: Ensure you use essential oils specifically designed for candles. Familiarize yourself with the oils’ flashpoints and control the wax temperature during candle-making to prevent premature evaporation.
External Factors:
- Burn in a Smaller Space: If you have a small-sized candle, it’s advisable to use it in a relatively smaller space, such as a bedroom, bathroom, or a small office. Square-shaped rooms are more conducive to even diffusion.
- Insufficient Burn Time: For candles made with natural plant-based wax, such as soy wax, it may take around half an hour for effective diffusion to occur. This is because these waxes have a higher melting point, requiring time to melt and release the essential oils. Paraffin wax may diffuse faster, but it’s less healthy. If you want quicker diffusion, you can try using a wax melter with wax melts.
- Avoid Drafty Areas: Don’t place burning candles in areas with strong airflow, as unstable candle flames can affect diffusion. Prolonged exposure to drafts can also shorten a candle’s lifespan.
