Tallow is a type of animal fat that has been used for centuries for various purposes, including candle-making. Today, candle-makers typically add fragrance oils to their wax blends to create scented candles. The maximum fragrance load of tallow refers to the maximum percentage of fragrance oil that tallow can hold without affecting its performance. This is an important factor in candle-making, as it determines the amount of fragrance oil needed to achieve the desired scent strength while maintaining the quality of the candle.

What You'll Learn
The maximum fragrance load depends on the wax
The maximum fragrance load depends on the type of wax used. It is usually safe to assume a fragrance load of 5% to 6% if it is not listed or cannot be found. The fragrance oil weight to add to the wax is calculated by multiplying the chosen fragrance load (in percentage) by the weight of the wax.
For example, if you are using a wax with a maximum fragrance concentration of 10% and you are making a 16 oz. candle, you can add up to 1.6 oz. of fragrance oil (16 oz. * 10% = 1.6 oz.). It is important to not exceed the recommended fragrance load, as this can result in issues such as poor burning characteristics or sweating, where the excess fragrance seeps from the candle.
When determining the fragrance load, it is crucial to follow the manufacturer's guidelines for the specific wax being used. The specification is usually available on the wax supplier's website. It is also important to note that just because a wax can hold a lot of fragrances, it does not mean it should. A candle with a high fragrance load may end up smelling like burning fuel instead of the desired scent.
In addition to the type of wax, the fragrance load can also depend on the type of fragrance oil being used. Essential oils, for example, are not suitable for candles and can cause inconsistent results. Candle makers should use scents specifically formulated for candles, which can be purchased from candle supplies companies.

Tallow is animal fat with a distinct smell
Tallow is a rendered animal fat, most commonly sourced from beef. It has been used for thousands of years across various applications, from skincare to cooking. When rendered, tallow is cooked down to a liquid state, and it solidifies at room temperature.
Tallow has a distinct, mild "animal" smell. This scent can be masked with essential oils or fragrance oils, particularly in products like candles and skincare balms. The fragrance load of tallow, or the amount of fragrance oil added, is typically around 5-6% of the weight of the tallow, but this can vary depending on the desired strength of the fragrance.
The process of rendering tallow can impact its smell. For instance, the wet method, which involves using water and salt to render the fat, can help prevent an unpleasant odour in the finished product. The type of animal fat used can also affect the scent; beef tallow, for example, may have a slight "beefy" smell, while lard might have a "piggy" odour.
Additionally, the oxidation of tallow during heating can produce different fragrances. Aishima and Nobuhara, for instance, treated tallow with air heating at 150-170°C, resulting in a "roast beef" essence. On the other hand, Haring prepared a "stewed" flavour by using mild oxidation to increase the content of certain compounds in the tallow.
In summary, tallow is a versatile animal fat with a distinct, mild animal scent that can be masked or altered through various methods, such as adding fragrance oils, using specific rendering techniques, or controlling the oxidation process during heating.

Essential oils don't work in candles
The maximum fragrance load of tallow is not clear, but a safe starting point for fragrance load is 5%. This can be calculated by multiplying the weight of your wax by 0.05, which will give you the weight of the fragrance oil to add.
Essential oils are not the best option for scented candles, and there are several reasons why. Firstly, essential oils are not always safe, even though they are natural. Some essential oils can release substances known as CMRs (carcinogenic, mutagenic, or reprotoxic) when heated to high temperatures, as is the case with candles. This can compromise the safety of the candle and introduce unexpected risk factors.
Secondly, essential oils often do not mix well with waxes. For example, soy wax tends to overpower the scent of essential oils, and beeswax can also be problematic. This can lead to uneven fragrance distribution or candles with little to no scent when lit. The texture and burn of the candle may also be affected, impacting its effectiveness and aesthetic appeal.
Thirdly, essential oils typically lose their scent quickly when exposed to heat, requiring frequent refills without ensuring consistent diffusion. Heat can also alter the chemical composition of some oils, changing a sweet scent into an unpleasant odour.
Finally, essential oils are costly and require large quantities to achieve a sufficiently strong fragrance.
For these reasons, it is recommended to use fragrances specifically designed for candles, which offer a safer, more effective, and long-lasting solution. These fragrances are formulated to be heated and provide a consistent, pleasant scent without the risks associated with essential oils.

Fragrance load is the maximum amount of fragrance a wax can retain without performance issues
Fragrance load is a crucial aspect of creating a well-balanced and appealing scented candle. It refers to the maximum amount of fragrance oil that can be added to the wax without causing performance issues or affecting its burn quality. The fragrance load is determined as a percentage of the total weight of the candle, including both the wax and the fragrance oil.
When creating scented candles, it is essential to follow the manufacturer's guidelines for the specific type of wax being used. Each wax type has a maximum fragrance load that it can safely handle, and exceeding this limit can lead to issues such as poor burn performance, safety concerns, or "sweating," where excess oil seeps out of the wax. Therefore, it is recommended to stay within the safe range of 5% to 6% fragrance load unless specified otherwise by the manufacturer.
The calculation of fragrance load involves multiplying the chosen fragrance load percentage by the total weight of the candle. For example, if you are making a 16 oz candle with an 8% fragrance load, you would need 1.28 oz of fragrance oil and 14.72 oz of wax. This calculation ensures that the candle has a pleasant scent without being overwhelming.
Additionally, it is important to note that different waxes absorb fragrance differently. Some waxes, like paraffin wax, have a lower scent capacity, typically around 3%, while pre-blended waxes or those with additives can hold higher fragrance loads, sometimes up to 12%. The type of fragrance oil used also plays a role, as lighter oils may require a higher percentage to be effective.
By understanding the concept of fragrance load and following the recommended guidelines, candle makers can create scented candles that not only smell amazing but also perform optimally, providing a pleasant and safe experience for their customers.

The fragrance load of a wax can be calculated mathematically
The maximum fragrance load depends on the type of wax being used. For example, paraffin wax IGI 4627, considered one of the best container waxes on the market, has a maximum fragrance load of 12%, which is relatively high. If you're working with a wax that doesn't specify its maximum fragrance load, it is generally safe to assume a fragrance load of 5-6%.
To calculate the amount of fragrance oil to add, you can use a simple formula. First, determine the weight of the wax you'll be using for your batch of candles, measuring in ounces or grams. Then, multiply the weight of your wax by the chosen fragrance load (expressed as a decimal). For example, if you're using 16 ounces of wax with a maximum fragrance load of 10%, you would calculate 16 oz * 0.10 = 1.6 oz of fragrance oil.
It's important to follow the manufacturer's guidelines for the specific wax you're using. Exceeding the recommended fragrance load can lead to issues such as poor burning characteristics or "sweating," where excess fragrance seeps out of the candle. Additionally, while a wax may be capable of holding a high fragrance load, it doesn't always mean it should be maximized, as this can result in an unpleasant scent, such as burning fuel.
In the context of tallow, which is rendered animal fat, one source suggests that 5% is a safe starting point for fragrance load. For example, if you're using an 8 oz jar, you would first calculate the weight of the wax by multiplying the volume by its specific gravity. Tallow has a specific gravity of approximately 0.87-0.9, so an 8 oz jar would contain approximately 7.2 oz of wax (8 * 0.9 = 7.2). To achieve a 5% fragrance load, you would then calculate 7.2 oz * 0.05 = 0.36 oz or 10.206 grams of fragrance oil. It's worth noting that essential oils are typically not suitable for candles, and fragrance oils specifically designed for candles should be used instead.
