When making candles, the ratio of fragrance to soy wax is crucial. The amount of fragrance you use can make or break your candle. The general rule of thumb is 1 ounce of fragrance oil to 1 pound of wax, which equates to a fragrance load of 6.25%. However, some candle makers have experimented with fragrance loads ranging from 7% to 20%. It's important to note that adding too much fragrance can cause issues such as sweating, where excess oil beads on the candle's surface, or separation, which can be a fire hazard. Other factors to consider include the pour temperature, the flash point of the fragrance, and the type of wax used.

The ideal fragrance load for soy wax candles is between 6% and 10%
When measuring the wax and fragrance, you can use grams or millilitres, but it's important to stick to one unit of measurement for accuracy. Before adding the fragrance, ensure that the wax temperature is below the flash point of the fragrance, generally between 50-55 degrees Celsius. The flash point is the temperature at which the fragrance becomes volatile and may catch fire. Adding the fragrance when the wax is too hot can also result in an uneven fragrance load, with the fragrance oil sweating out of the wax or pooling on the surface.
It's also crucial to consider the type of soy wax you're using. Soy wax is known for its challenges in achieving a smooth, even finish, and it may not provide a strong hot throw of fragrance. If a stronger scent is desired, consider using a wax melter with a larger diameter or try a paraffin wax, as soy wax may not provide the desired fragrance intensity. Additionally, some fragrances may require a higher percentage to achieve the desired scent, so experimentation is often necessary.
Finding the right fragrance load for soy wax candles may take some trial and error. It's important to take detailed notes during the process to avoid repeating unsuccessful attempts. By adjusting the fragrance percentage, curing time, and pour temperature, you can create soy wax candles with a pleasant fragrance and a smooth, even appearance.

The temperature of the wax should be below the fragrance's flash point before adding the fragrance
The ideal temperature for adding fragrance to soy wax is a topic of debate among candle-makers. While some sources recommend adding fragrance to soy wax at a temperature of around 185°F (85°C), others suggest that the wax temperature should be below the flashpoint of the fragrance oil, which is generally between 50°-55°C, but can vary.
The flash point of a fragrance oil is the temperature at which it becomes volatile and may catch fire. It is important to ensure that the wax temperature does not exceed the flash point of the fragrance oil to avoid any safety hazards. However, adding fragrance oil to wax that is too cool can also be an issue, as the oil may not dissolve properly and may pool at the bottom of the container.
To ensure proper bonding between the fragrance and the wax, it is crucial to heat the wax beyond the melting point of the soy wax, which is typically around 140°F. This allows the fragrance oil to mix thoroughly with the wax, resulting in an even fragrance load in the final candle product.
It is worth noting that the temperature of the wax can also impact the performance of the candle. For example, soy wax can discolor or undergo other changes when heated to excessively high temperatures (around 245°F or higher). On the other hand, adding fragrance oil to wax that is too cool may result in a reduced scent throw or fragrance leaching out of the wax.
Finding the ideal wax temperature for adding fragrance may require some trial and error. Candle-makers can refer to the temperature recommendations provided by the wax manufacturer and fragrance oil supplier to ensure optimal results. Additionally, using a thermometer to accurately measure the wax temperature can help achieve consistent results, especially when making large batches of candles.

The flash point of fragrances is generally between 50-55°C
When making candles, it is important to understand the ratio of fragrance to soy wax and the flash point of the fragrance. The flash point is the temperature at which the fragrance becomes volatile and may catch fire. The flash point of fragrances is generally between 50-55°C, but this can vary depending on the type of wax and fragrance used. It is important to only add the fragrance when the wax temperature is below the flash point to ensure safety and avoid any potential ignition.
To determine the ratio of fragrance to soy wax, one must consider the desired fragrance load, which is typically between 6-10% of the total weight of the wax. For example, if you are using 300g of soy wax, you would use between 18g and 30g of fragrance oil. However, it is important to note that different fragrances can affect soy wax differently, so adjustments may be necessary. Some fragrances may cause the wax to set lumpy or curdle, in which case the fragrance load should be reduced.
Additionally, the pour temperature and the temperature at which the fragrance is added can impact the final product. It is recommended to experiment with these temperatures to find the optimal range for the specific fragrance and wax combination. When working with soy wax, it is important to keep in mind that it can be difficult to achieve a smooth and even finish, even with the use of heat guns and cooling racks.
Furthermore, the quality of the fragrance oil is important. Cheap oils intended for diffusers may not be suitable for candle-making and can affect the final product's appearance and performance. It is recommended to purchase fragrance oils from reputable candle supply companies or companies that specialise in candle-making ingredients. Proper curing of the candle, typically for at least two weeks, is also crucial for optimal fragrance throw.
In summary, when working with soy wax and fragrance oils, it is important to consider the flash point of the fragrance, the desired fragrance load, the quality of ingredients, and the curing process. By understanding these factors and through experimentation, one can create well-balanced and safe candles with optimal fragrance performance.

Candle sweating can be caused by high soy content, temperature changes, or adding too much fragrance
Candle sweating, which occurs when the fragrance oil separates from the wax, is a common issue experienced by owners of soy wax candles. Candle sweating can be caused by high soy content, temperature changes, or adding too much fragrance.
Soy wax is sensitive to temperature changes, which can cause the natural oils to separate from the wax and collect on the surface. This can happen when candles are moved from a cold environment to a hot one, or vice versa. To avoid this, candles should be stored in a cool, dry environment, away from drafts, direct sunlight, and rooms with varying temperatures.
The ratio of fragrance to soy wax is crucial in candle-making. If too much fragrance is added, it may not bind properly to the wax, causing sweating. To prevent this, it is important to add the fragrance when the wax temperature is below the flash point of the fragrance, generally between 50-55 degrees Celsius, and to mix the fragrance thoroughly.
High soy content in candles can also lead to sweating. This is because soy wax is more prone to releasing excess oil during temperature changes. To reduce sweating in soy candles, it is recommended to switch to a soy blend or non-soy wax, which can hold the fragrance better and reduce the likelihood of sweating.
In addition to the above, there are other factors that can contribute to candle sweating. Blowing out a candle can create drafts and temperature changes, so it is recommended to use a wick dipper to gently extinguish the flame. Trimming the wick to about a quarter of an inch before each use can also help ensure a controlled and even burn, reducing the likelihood of sweating.

The amount of fragrance oil per 100g of soy wax varies from 6-10%
The amount of fragrance oil added to soy wax is critical in candle-making. The general rule of thumb is to add 1 ounce of fragrance oil to 1 pound of wax (16 ounces). This equates to approximately 6-10% fragrance load by weight. For example, if you have 300 grams of soy wax, you would want to add between 18 and 30 grams of fragrance oil.
It is important to note that the percentage of fragrance oil added can vary depending on personal preference and the specific fragrance used. Some candle-makers have reported using fragrance loads of up to 15-20% to achieve a stronger scent throw. However, going over 10% fragrance load can cause issues such as seepage and sweating, where the fragrance oil separates from the wax and forms beads of oily residue on the surface of the candle. This is especially common with candles that have a very high soy content.
To avoid these issues, it is recommended to start with a lower fragrance load and increase it gradually until the desired scent strength is achieved. It is also important to allow the wax to cool to a temperature below the flashpoint of the fragrance, generally between 50-55 degrees Celsius, before adding the fragrance oil. This will help prevent the fragrance from becoming volatile and catching fire.
Additionally, when measuring the amount of fragrance oil to add, it is important to use either grams or milliliters, but not to mix the two units of measurement. This will ensure that the percentage of fragrance oil added is accurate.
