When making candles, it's important to calculate the fragrance load, which is the percentage of fragrance oil in the total weight of the candle. This is important because using too much fragrance oil can cause issues with the candle, such as tunnelling, poor scent throw, and wicks that won't stay lit. The standard fragrance load for a candle is between 5-10%, but it's important to be consistent in your calculations and transparent about your methods on product labels or packaging. For example, a 10% fragrance load means that 10% of the total weight of the candle comes from fragrance oil, while the other 90% comes from candle wax.

Calculating fragrance load
Calculating the fragrance load is an important step in making good-quality candles. The fragrance load is the percentage of fragrance that the chosen wax can hold. Using too much fragrance can lead to candles with dry or lumpy wax or even those that do not hold a flame.
The fragrance load is calculated as the ratio of fragrance oil to the weight of the wax. The fragrance oil percentage is based on the amount of fragrance in the total weight of the product. For example, if you have 30 grams of fragrance oil in 300 grams of wax, this gives a fragrance load of 10%. However, the total percentage of fragrance oil, for CLP purposes, is 30 grams in 330 grams (30 grams + 300 grams), which gives a CLP percentage of 9.09%.
The fragrance load can be calculated manually or using a pre-made calculator. To calculate it manually, you can use the following formula:
> (Weight of wax in oz or grams) x (% of fragrance oil in decimal form) = (Weight of fragrance oil in oz or grams)
For example, if you are using 32 oz (908 grams) of wax and want to use 6% fragrance oil, the calculation would be:
908 grams x 0.06 = 54.48 grams of fragrance oil
Online calculators can also be used to simplify the process. These calculators typically require you to input the desired candle weight and the percentage of fragrance oil you want. They may also allow you to specify the container size and the number of candles in the batch.
It is important to note that the fragrance load can vary depending on the type of candle wax used. The average fragrance load is typically between 5-6%, but some waxes can hold up to 10% fragrance. It is recommended to stay below 7% fragrance load to avoid wicking issues.

Common issues with a 10% fragrance load
When creating scented candles, it's important to understand the concept of fragrance load and the issues that can arise when working with a 10% fragrance load.
Fragrance load refers to the amount of fragrance oil in a candle as a percentage of the total weight. There are two common methods to calculate this percentage: relative to the wax or relative to the total blend of wax and oil. The first method, known as Fragrance Load, calculates the ratio of oil to wax only. The second method, known as Fragrance Content, takes into account the total weight of wax and oil combined. Consistency and clarity in calculations are crucial, especially for accurate labelling.
Now, let's delve into some common issues that can occur when working with a 10% fragrance load:
- Wicking Issues: When the fragrance load exceeds 7%, wicking problems may arise. The wick may struggle to burn properly, resulting in a small flame or, in some cases, the flame dying out completely. This can lead to candle tunnelling, where the candle burns down the centre, leaving hard wax around the edges.
- Poor Scent Throw: An overloaded wick may fail to achieve a full melt pool, impacting the release of fragrance. This results in poor hot throw, where the candle fails to release an adequate amount of fragrance when burned.
- Burning Characteristics: Exceeding the recommended fragrance load can lead to poor burning characteristics. The candle may not burn efficiently, and the excess fragrance may seep out of the candle, resulting in an uneven burn.
- Labelling Inaccuracies: It is important to accurately calculate the fragrance load to ensure compliance with CLP (Classification, Labelling, and Packaging) regulations. Inaccurate calculations can lead to misleading labels, affecting consumer trust and potentially resulting in non-compliance with regulatory requirements.
- Calculations and Consistency: Achieving a precise 10% fragrance load requires accurate calculations. Minor errors in measurements or calculations can result in an overloaded or underloaded candle, impacting the overall quality and performance.
- Dye Compatibility: When incorporating dye into your candles, the calculations can become more complex. The weight of the dye must be factored in, and ensuring compatibility between the fragrance oil and the dye becomes crucial to avoid separation or undesirable reactions.
To mitigate these issues, it is essential to follow manufacturer guidelines, maintain consistency in your calculations, and be transparent about your methods on product labels. Additionally, using a fragrance load calculator can simplify the process and help you achieve the desired fragrance load without encountering these common issues.

Using a fragrance load calculator
Calculating the fragrance load for your candles is important to ensure you produce good-quality candles. Using too much fragrance can result in candles with dry or lumpy wax or even those that do not hold a flame. The fragrance load is usually between 5-6% but depends on the type of candle wax you are using.
There are many fragrance load calculators available online, most of which are free to use. These calculators can help you determine the perfect amount of fragrance oil for your candle and wax melt projects. To use these calculators, you will need to enter the following information:
- The number of candles you wish to produce.
- The container size and the unit of measurement (ounces, grams, or pounds).
- The desired fragrance load percentage.
- The type of wax you are using.
- The wax gravity for the wax you are using.
For example, let's say you want to make 100 candles with a container size of 220 grams each. You decide to use a fragrance load of 10%. The calculator will then determine the amount of fragrance oil and wax needed for each candle. In this case, you would need 22 grams of fragrance oil and 198 grams of wax per candle.
It is important to note that the fragrance load percentage is based on the ratio of fragrance oil to the total weight of the product, including the wax. So, when 10% is given as the fragrance load, it means that 10% of the total weight of the product comes from the fragrance oil, and the other 90% comes from the candle wax.
Additionally, if you are using dye in your candles, such as Bekro dye at 0.2%, you can use the fragrance load calculator to adjust your values accordingly. The dye weight can be calculated relative to the total mass of wax or based on the total mass of the candle, including the fragrance oil.

The importance of consistency
Consistency is key when creating scented candles. The fragrance load, or scent load, is the ratio of fragrance oil to the weight of the wax. This ratio is important because it determines the strength of the scent and the overall quality of the candle. A higher fragrance load does not necessarily mean a stronger scent, as an overload of fragrance oil can lead to issues such as tunnelling, poor scent throw, and wicks that struggle to stay lit or won't light at all.
To ensure consistency in your candles, it is important to accurately calculate the fragrance load. This can be done manually or by using a fragrance load calculator. The manual calculation involves determining the desired candle weight and the percentage of fragrance oil desired. For example, if you want a 10% fragrance load for a 300g candle, you would need 30g of fragrance oil and 270g of wax. However, it's important to note that this calculation assumes the container weight is included in the desired candle weight.
Another way to calculate fragrance load is by using the fragrance load relative to the total container mass. This method takes into account the container that the candle will be poured into. For example, if you have a container that weighs 220g and you want a 10% scent load, you would need 22g of fragrance oil and 198g of wax. This method ensures that the fragrance load is calculated relative to the total weight of the candle, including the container.
Using a fragrance load calculator can simplify the process and ensure accuracy. These calculators take into account various factors such as the number of candles, container size, fragrance load percentage, and wax gravity. By inputting these values, the calculator will determine the exact amount of wax and fragrance oil needed to maintain consistency across your candles. Consistency in fragrance load ensures that your customers receive a uniform product with a pleasant scent and proper burning characteristics.
