Adding fragrance oil to a candle is a great way to make it stand out. However, getting the timing right is crucial to the candle's performance. Adding the oil too early or too late can affect the scent throw, which is the strength of the candle's fragrance when it is burned.
It's important to know the melting point of the wax you are using, as this will determine the ideal temperature for adding fragrance oil. For example, if you are using soy wax, it is recommended to begin mixing at around 155°F–165°F (68°C–74°C). Once the wax is fully melted, you can add the fragrance oil and stir well.
Stirring the mixture for several minutes is also crucial. Inadequate stirring can prevent the fragrance oil from binding to the wax, causing it to settle at the bottom and resulting in a weak scent throw.
Additionally, it is important to note that fragrance oils have a flash point, which is the temperature at which they become combustible. Adding fragrance oil to wax at too high a temperature can potentially be dangerous if it exceeds the flash point. Always refer to the manufacturer's instructions for the recommended flash point of your fragrance oil.

Fragrance oil's flash point is listed on the packaging
Candle-making is a fun and rewarding hobby, but it's important to understand the science behind it to ensure safety and effectiveness. One key aspect is adding fragrance oils at the right temperature to achieve a consistent and fragrant candle.
The flash point of a fragrance oil is the temperature at which it can catch fire or change its composition. This is an important factor in candle-making, as adding fragrance oil to a base that exceeds its flash point can alter its chemical structure, resulting in a different scent. Flash points are typically listed on the packaging of fragrance oils, and they vary depending on the type of oil. For example, gel candles require fragrance oils with a flash point of 170°F or higher for safety reasons.
When adding fragrance oil to candle wax, it is generally recommended to do so when the wax temperature is within the range of 185°F to 200°F (85°C – 93°C). This temperature range ensures that the fragrance oil binds effectively with the wax, resulting in a stronger scent throw. It is important to stir the mixture for several minutes to prevent the oil from settling at the bottom, which can also lead to a weak scent.
However, it's a common misconception that heating fragrance oil above its flash point will ruin its hot throw. This belief is false and potentially dangerous. Fragrance oil has a much higher boiling point than typical candle-making temperatures, so it is unlikely to degrade during the process. Adding fragrance oil at too low a temperature can create pools of oil within the candle, increasing the risk of violent ignition. Therefore, it is crucial to follow the recommended temperature guidelines for adding fragrance oil to candle wax.
Additionally, it's important to use fragrance oils specifically designed for candle-making and to avoid using alternatives like perfume. The recommended amount of fragrance oil should also be followed to prevent overload, which can create a fire hazard and affect the scent throw.

Citrus and herbal oils may burn off too quickly or smell off
When making candles, it is important to consider the type of fragrance oil used, as some oils may burn off too quickly or produce an unpleasant smell. Citrus and herbal oils, in particular, can be challenging to work with due to their low flash points.
Citrus oils, such as orange oil, have very low flash points and are known for their poor performance in candles. They tend to burn off quickly and may produce an undesirable fume-y or gassy smell. This is because the flash point of essential oils is much lower than that of fragrance oils, causing them to evaporate more rapidly when used in candles.
Herbal oils can also be tricky to work with. Some herbal oils, such as menthol and camphor, can release toxic compounds when burned, posing health risks to people with asthma or other respiratory issues. Additionally, when burned, herbal oils can produce an off-putting diesel or camphor-type smell, detracting from the desired fragrance of the candle.
To avoid these issues, it is recommended to use fragrance oils specifically designed for candle-making. These oils have been formulated to withstand higher temperatures without degrading or altering their scent. They typically have higher flash points than essential oils, resulting in a more stable fragrance that is less likely to burn off too quickly.
It is also important to test fragrances before committing to a large batch. By creating small test candles and evaluating their performance, you can ensure that the fragrance oil is compatible with the wax and that the scent is pleasant and long-lasting. This proactive approach can save time and resources in the long run.

Coconut oil can be added to reduce frosting and increase adhesion
Coconut oil can be added to soy wax candles to reduce frosting and increase adhesion. Frosting refers to the formation of white crystals or snowflake-like patterns on the surface of a candle, which can detract from its overall appearance. While frosting does not impact the performance of the candle, it is a common issue encountered by candle makers, especially with soy wax.
Coconut oil has been found to effectively reduce frosting in soy candles. It is recommended to use 1/2 teaspoon of coconut oil per pound of wax to help minimise wet spots and frosting. This addition of coconut oil contributes to a smoother and more uniform texture, enhancing the overall aesthetic appeal of the candle.
Coconut oil also improves adhesion, ensuring that the wax adheres well to the sides of the container. This prevents the formation of gaps or wet spots, resulting in a clean and high-quality finish. The excellent adhesion properties of coconut oil provide a strong bond between the wax and the container, minimising shrinkage during the cooling process.
Additionally, coconut oil can be blended with soy wax to increase the shelf life of candles. The combination of coconut and soy waxes enhances burn time and slows down the burn rate, allowing for extended enjoyment of the candle. This blend also improves fragrance throw, creating strongly scented candles that fill rooms with aromas.
When adding coconut oil to soy wax, it is important to consider the temperature. The recommended pouring temperature for soy wax is around 135° F, but it can vary between 160-175° F depending on the brand and blend. For adding fragrance oils, the ideal temperature range is between 180° F and 200° F (85° C – 93° C) to ensure a safe and stable candle.

The pouring temperature depends on the wax blend/brand
The pouring temperature for candles depends on the type of wax used. Different waxes have different melting points, and the temperature at which fragrance oil should be added varies accordingly.
For soy wax, the ideal temperature for adding fragrance oil is between 155°F and 185°F (68°C and 85°C). This range ensures that the wax is fluid enough to mix thoroughly without overheating. It is recommended to heat the wax to around 50°F to 60°F above its melting point before adding the fragrance. For example, if your soy wax melts at 125°F, heat it to around 175°F to 185°F before adding the fragrance. This ensures proper blending and sets the stage for a successful pour.
Once the fragrance is mixed in, it is crucial to let the wax cool before pouring it into containers. The optimal pouring temperature for soy wax is between 120°F and 140°F (49°C and 60°C). Pouring at a lower temperature can provide better jar adhesion, a smoother finish, and reduced shrinkage. However, it is important to ensure that the wax doesn't cool down too much, as this can cause issues with the wax setting properly.
Other types of wax, such as paraffin and palm wax, have different ideal temperatures for adding fragrance oil. For paraffin wax, the recommended temperature is around 180°F to 185°F (82°C to 85°C). Palm wax has an even higher ideal temperature range of 200°F to 205°F (93°C to 96°C).
It is worth noting that the brand and specific blend of wax can also impact the ideal pouring temperature. Different brands may have varying melting points, and blends with different additives or natural waxes may require adjustments in temperature. Therefore, it is always important to refer to the manufacturer's instructions or recommendations for the specific wax you are using.
Additionally, it is crucial to use a thermometer to monitor the temperature throughout the candle-making process. This helps prevent scorching the wax and ensures that fragrance oil is added at the appropriate temperature for the particular wax blend you are working with.
