It is important that the fragrance oil binds and mixes completely with the melted wax. For this reason, we generally recommend adding fragrance oil to your wax between 180-190°F (82-88°C), regardless of the [flashpoint](https://support.candlescience.com/en_us/what-does-the-fragrance-flashpoint-mean-H1whhmgsZl) of the fragrance oil. This is the optimal temperature range for most fragrances and waxes to bind together, which will provide the best fragrance throw in your finished candle. We have confirmed this through rigorous testing in our in-house labs. Adding fragrance to your wax at lower temperatures can result in the fragrance not binding properly with the wax. This would negatively impact the scent throw, and in a worst-case-scenario, cause the fragrance to leach out of the wax and pool on the top or bottom of your candle.

The pouring temperature (the temperature at which you pour the fragranced wax into the container) will depend on the type of wax you're using. Be sure to check the wax product page for the pouring temperature for your specific wax.
