The fragrance load of soy wax is the maximum amount of fragrance it can retain without affecting performance
The fragrance load of a candle refers to the maximum amount of fragrance oil it can retain without compromising the quality of the candle. This is usually expressed as a percentage of the total wax weight. For example, a 7% fragrance load in a 170-gram soy candle means using 13.6 grams of fragrance oil.
When making soy candles, the fragrance load typically ranges from 6% to 10%. However, some sources mention fragrance loads of up to 12%. It's important to note that going over 10% can cause issues like separation and fragrance oil sweating out of the wax, creating a fire hazard.
The fragrance load is crucial in achieving the desired scent throw, which is how well the candle's fragrance permeates the space when lit. A balanced fragrance load results in a soy candle that fills the room with a pleasant aroma and burns evenly, maintaining a smooth appearance. On the other hand, an incorrect fragrance load can lead to problems like tunneling, sooting, and an uneven wax pool.
To master the art of soy candle-making, it's essential to understand the concept of fragrance load, measure and calculate it accurately, and conduct test burns to ensure a high-quality, fragrant end product.

The percentage of fragrance oil added to soy wax determines the scent's intensity and the candle's burn characteristics
The fragrance load of a candle refers to the maximum amount of fragrance oil that can be added to the candle wax without affecting its performance. This percentage of fragrance oil added to soy wax is critical as it determines the scent's intensity and the candle's burn characteristics.
When crafting a soy candle, understanding the fragrance load is essential to achieving the desired scent throw and burn quality. The scent throw refers to how well the candle's fragrance permeates the space when lit, while burn quality encompasses factors such as an even burn, a smooth appearance, and the absence of issues like tunneling and sooting.
The percentage of fragrance oil added to soy wax typically ranges from 6% to 10%. Some sources suggest that fragrance loads of up to 12% are possible with pre-blended waxes or those containing additives. However, it is important to note that exceeding the recommended fragrance load for a particular wax can lead to problems such as sweating, where the excess fragrance seeps out, or poor burning characteristics.
To calculate the fragrance load, one must determine the weight of the soy wax and then apply the desired fragrance load percentage. For example, for a 7% fragrance load in a 170-gram soy candle, you would calculate 170 grams x 0.07 = 11.9 grams of fragrance oil required. It is crucial to use high-quality, candle-safe fragrance oils and conduct test burns to assess the scent throw and burn characteristics.
Additionally, the type of fragrance oil used can impact the fragrance load. Oils with stronger scents, such as vanilla, may be used at a lower percentage, while lighter fragrances like citrus or herbal oils may require a higher percentage to achieve the desired scent throw. The pouring temperature of the wax and the type of container used also play a role in the overall performance of the candle.

The fragrance load of soy wax candles can be calculated by weight or volume
The fragrance load of a candle refers to the maximum amount of fragrance oil that can be added to the wax without affecting its performance. The fragrance load is usually expressed as a percentage of the total wax weight. For example, a 7% fragrance load means that there are 7 grams of fragrance oil for every 100 grams of wax.
Some candle makers prefer to measure the wax and fragrance oil in millilitres instead of grams. As long as you stick to one unit of measurement, the percentage added will be correct. However, it is important not to mix grams and millilitres when measuring. When making a single candle, it is also important to know the volume of your candle container and how much fragrance oil to use.
The recommended fragrance load for soy wax candles typically ranges from 6% to 10%. Some sources suggest that a good starting point is 1 ounce of fragrance oil per 16 ounces (1 pound) of wax, resulting in a fragrance load of approximately 6.25%. However, exceeding this recommended range can cause issues such as poor burning characteristics, sweating (where the excess fragrance seeps out), and even safety hazards.
It is also important to note that the fragrance load can impact the performance and quality of the candle. A balanced fragrance load results in a soy candle that fills the room with a delightful aroma and burns evenly, maintaining a smooth appearance. On the other hand, an incorrect fragrance load can lead to issues such as tunneling, sooting, and an uneven wax pool. Therefore, it is crucial to conduct test burns, assess the scent throw and burn characteristics, and make necessary adjustments to achieve the desired fragrance load.

The fragrance load of soy wax can be impacted by the addition of other oils and butters
The fragrance load of soy wax is the maximum amount of fragrance that the wax can retain without affecting its performance. It is expressed as a percentage and determines how much fragrance oil should be added to achieve the desired scent strength without compromising the quality of the candle. For instance, a fragrance load of 6% - 8% is generally recommended to ensure a good scent throw without impacting the flame's ability to burn through the viscous fragrance oil or causing disturbances to the top of the candle.
The fragrance load can vary depending on the type of wax and the manufacturer's guidelines. For example, paraffin wax typically has a lower scent capacity of around 3%, while pre-blended waxes or those with additives can hold higher fragrance loads of up to 12%. Soy wax is known for its high fragrance load capability, with some sources stating a minimum of 10% fragrance load.
When adding fragrance oil to soy wax, it is important to ensure that the wax temperature is below the flash point of the fragrance, generally between 50-55 degrees Celsius. Adding the fragrance at a lower temperature can help prevent issues such as sweating, where excess fragrance seeps from the candle, and ensure a more even fragrance load.
Now, regarding the impact of adding other oils and butters to soy wax, it is important to note that this can affect the fragrance load. For example, some candle makers recommend adding a small amount of fractionated coconut oil to soy wax to reduce frosting and increase glass adhesion. However, this additional oil will need to be accounted for in the overall fragrance percentage, as soy wax can only encapsulate a limited amount of oil. Therefore, adding coconut oil may reduce the amount of fragrance oil that can be added and result in a lower fragrance load.
Additionally, the type of fragrance oil used can also impact the fragrance load. For example, citrus and some herbal oils, particularly those made primarily of essential oils, have a lighter density and may burn off too quickly or produce an unpleasant smell. In such cases, it is recommended to add these oils at a lower temperature and/or blend them with a higher-density oil to achieve the desired fragrance load and scent throw.

The fragrance load of soy wax can be impacted by the temperature at which the fragrance is added
The fragrance load of soy wax is the percentage of fragrance oil mixed into the wax. The temperature at which the fragrance is added to the wax can impact the fragrance load of soy wax.
The ideal temperature for adding fragrance to soy wax is between 155°F and 185°F (68°C and 85°C). If the wax is too cool when the fragrance is added, they won't bind properly, which can lead to a poor scent throw or fragrance seepage. On the other hand, if the wax is too hot, it can cause the fragrance oil to sweat out of the wax, which is a fire hazard.
The flash point of a fragrance is the temperature at which it becomes volatile and may catch fire. It is important to add the fragrance when the wax temperature is below the flash point of the fragrance, generally between 50°C and 55°C. However, the flash point can vary depending on the type of wax and fragrance used.
The ratio of fragrance oil to wax is critical for achieving the desired scent throw. The recommended fragrance load for soy wax is between 6% and 10%. However, some sources suggest that a higher fragrance load of up to 15% to 20% can be used for a stronger scent, while others recommend a lower load of 5% to 6% for a subtler aroma. It is important to experiment with different percentages to find the optimal fragrance load for a particular scent and wax combination.
The pouring temperature of the wax also plays a crucial role in fragrance load. The ideal pouring temperature for soy wax is between 120°F and 140°F (49°C and 60°C). Pouring at too high a temperature can cause the wax to shrink and create holes or dips in the candle. Additionally, the type of wax and fragrance used can affect the pouring temperature, so it is important to refer to the manufacturer's recommendations.
