Adding fragrance to candles and wax melts is a delicate process. The amount of fragrance oil added to the wax depends on the type of wax, the flashpoint of the fragrance oil, and the desired strength of the scent. The warmer a fluid is, the more it wants to release vapours into the atmosphere. If the flashpoint of the fragrance oil is low and it is added to wax that is too hot, the scent will evaporate as the candle cools and sets. Most waxes will hold no more than 12% of fragrance oil, but a lower percentage is recommended to maintain the stability of the candle or wax melt.

What You'll Learn
The percentage of fragrance oil depends on the type of wax used
The percentage of fragrance oil you use in wax melts depends on the type of wax used, the strength of the scent, and the flashpoint of the fragrance oil. Most waxes will hold no more than 12% fragrance oil, but a higher percentage may affect the stability of the wax melt. To ensure optimal scent throw without compromising stability, it is recommended to use 10% fragrance oil. This means that for every 100 grams of wax, 90 grams should be wax, and 10 grams should be fragrance oil.
For a more subtle scent, you can reduce the percentage of fragrance oil to 6% or slightly lower. It is important to note that some fragrances may be heavier than others and require less fragrance oil to achieve the desired scent throw. For example, scents like vanilla, sandalwood, oudh, and caramel can be reduced to a 6% fragrance load. Additionally, the pour temperature can impact the scent throw, so it is recommended to experiment with different temperatures to find the right balance.
The type of wax used also plays a role in determining the percentage of fragrance oil. For example, when using soy wax, it is recommended to use a fragrance load of 6% to 8% to ensure a good scent throw without impacting the flame's ability to burn through the viscous fragrance oil. However, testing is key, and the percentage may vary based on the specific type of wax used.
The flashpoint of the fragrance oil is another factor to consider. The flashpoint is the temperature at which the fragrance oil will ignite when exposed to an open flame. If the flashpoint of the fragrance oil is low, and it is added to heated wax at a higher temperature, the scent will evaporate as the wax cools, resulting in a loss of fragrance. Therefore, it is important to consider the flashpoint when determining the percentage of fragrance oil to use.

The flashpoint of the fragrance oil is important
The flashpoint of fragrance oil is the temperature at which the oil can combust if exposed to an open flame or spark. This is important to know for two key reasons. Firstly, for safety during the candle-making process, and secondly, for compliance with shipping regulations.
When making candles, it is important to understand the flashpoint of the fragrance oil being used, as this will indicate the temperature at which the oil could catch on fire. This is particularly important if you are making gel candles, as certain types of oils with higher flashpoints are required for this process. For example, Penreco recommends using fragrance oils with flashpoints over 170°F for gel waxes.
It is worth noting that adding fragrance oil to wax above the oil's flashpoint will not cause it to combust. As long as the fragrance is added to the wax and poured soon, it will not lose strength. However, it is not recommended to repeatedly cool and reheat batches of fragranced wax, as this could affect the strength of the fragrance. Instead, it is better to limit batch sizes to an amount that can be poured right away.
The flashpoint of fragrance oil is also important for shipping purposes. Fragrance oils with low flashpoints, typically those with a flashpoint of 141°F or less, are unable to be shipped via air and must be shipped via ground services. This is due to the increased risk of combustion during transportation. By knowing the flashpoint of the fragrance oil, manufacturers and distributors can ensure they are compliant with shipping regulations and safely transport their products.
In summary, the flashpoint of fragrance oil is important as it indicates the temperature at which the oil can combust, impacting both the candle-making process and shipping requirements. By understanding the flashpoint, candle makers can ensure they are using the appropriate type of oil for their specific application and comply with relevant safety regulations.

The strength of the scent is a key factor
Most waxes will hold no more than 12% fragrance oil, but to ensure candle stability, it is recommended to use 10% fragrance oil for optimal scent throw. This means that for a 100g candle, 90g should be wax, and 10g should be fragrance oil. If you prefer a more subtle scent, you can reduce the fragrance oil to 6% or higher.
It's important to note that fragrance load (FL) refers to the percentage of fragrance oil mixed into your wax. For example, a 10% fragrance load means adding 10% of the total wax mass as fragrance oil. This calculation will increase the total mass of your product. For instance, adding 10g of fragrance oil to 100g of wax results in a total mass of 110g.
The type of fragrance you choose will also impact the percentage of fragrance oil needed. Some scents are heavier than others and require less fragrance oil. Fragrances with vanilla, sandalwood, oudh, or caramel can be reduced to a 6% fragrance load. Additionally, the pour temperature can affect the scent, so it's important to experiment with different temperatures when creating your wax melts.
When determining the percentage of fragrance oil, it's crucial to consider the container size. Measure the volume of your container and calculate the desired fragrance load accordingly. This will ensure that you add the appropriate amount of fragrance oil to your wax melts.
By considering the strength of the scent, the type of wax, the flashpoint of the fragrance oil, and the container size, you can determine the optimal percentage of fragrance oil to add to your wax melts, ensuring a pleasant and effective scent throw.

The density of the fragrance oil matters
To ensure accuracy, it is recommended to measure fragrance oil by weight (grams) rather than volume (ml). This way, you can achieve a more precise wax-to-fragrance-oil ratio. By measuring in grams, you account for the difference in densities and ensure a consistent fragrance load across different types of fragrance oils.
The recommended fragrance load for wax melts is typically around 6% to 10%. However, it's important to note that the type of wax used and personal preference can also influence this percentage. Some waxes have different maximum fragrance load percentages, so referring to the product information is crucial.
Additionally, when measuring fragrance oil, it's important to use a candle and soap scale. This specialized scale allows for accurate measurements, helping you achieve the desired fragrance load. By weighing the fragrance oil instead of solely relying on volume measurements, you can better control the scent throw of your wax melts.
In summary, the density of fragrance oil plays a crucial role in determining the appropriate fragrance load for wax melts. By considering the density and measuring the oil accurately, you can create a consistent and stable product with the desired scent throw. This attention to detail ensures that your wax melts not only smell appealing but also meet the expected quality standards.

The pour temperature of the wax can be adjusted
Once the wax has reached the desired temperature, you can add the fragrance oil. The amount of fragrance oil added depends on the type of wax used, the flashpoint of the fragrance oil, and the desired strength of the scent. Most waxes can hold up to 12% fragrance oil, but it is recommended to use 10% fragrance oil to ensure candle stability and optimal scent throw. This means that for a 100-gram candle, 90 grams should be wax, and 10 grams should be fragrance oil.
It is important to note that many fragrances have different densities, which can affect the accuracy of measurements. Therefore, it is recommended to measure fragrance oil in weight (grams) rather than volume (ml) to ensure a more accurate wax-to-fragrance-oil ratio. Additionally, the warmer a fluid is, the more it will release vapors into the atmosphere, so the flash point of the fragrance oil should also be considered when determining the pour temperature of the wax.
After adding the fragrance oil, stir the mixture thoroughly and then pour it into the desired container or mold. The pouring temperature can be adjusted by lowering it to between 140°F and 170°F, depending on the specific instructions for the type of wax used. Allow the wax to cool slowly and avoid placing it in a water bath or refrigerator to accelerate the cooling process, as this can affect the adhesion of the wax to the container.
