Using fragrance oils for candle making isn’t complicated. For the best results, remember to:

  • Precisely measure fragrance oil by weight.
  • Use a digital scale for accurate measurements.
  • Add the fragrance oil at the specified wax temperature.
  • Mix thoroughly to ensure even distribution.
  • Allow candles to cure before lighting them.
  • Experiment with the concentration of fragrance oil to achieve the desired scent throw.
  • Store unused fragrance oils in tightly sealed containers in a cool, dark place.

A little experimenting with small batches will help prevent wasting raw materials during larger production runs and maintain consistency in your finished candles.

The Importance of Fragrance Load

Fragrance load indicates how much fragrance oil is added to the wax.

Every type of candle wax has a recommended maximum fragrance capacity. Adding more fragrance oil than recommended does not guarantee a stronger scent throw. In fact, it may compromise the candle's burn quality and overall performance.

For the best results:

  • Follow the wax manufacturer's recommended fragrance load.
  • Perform test burns to determine the optimal fragrance percentage.
  • Adjust the fragrance level only after testing small batches.
