Soy wax is a popular choice for candle makers as it offers a long burn time and can hold a higher fragrance load compared to paraffin wax. When making a soy candle, the fragrance load typically ranges from 6% to 10% of the total weight of the wax. This means that for every pound of soy wax, you would generally add between 0.96 ounces and 1.92 ounces of fragrance oil. However, it's important to note that the percentage of fragrance used can vary depending on personal preference, the type of fragrance, and the manufacturer's objective for aroma diffusion.

A typical fragrance load for soy wax candles
The fragrance load in a candle typically ranges from 6% to 8% of the total weight of the wax. However, this can vary depending on preference, the type of fragrance used, and the type of wax. Soy wax, for instance, can hold a higher fragrance load compared to paraffin wax and will not diffuse as efficiently. Typically, a fragrance load of around 8% to 10% is used for soy wax candles. This means that for 1 pound (450 grams) of soy wax, you would generally add between 0.96 ounces (27 grams) and 1.92 ounces (54 grams) of fragrance oil.
It's important to note that the type of fragrance oil can also impact the fragrance load. Oils with a stronger scent, such as those containing vanilla, can be used at a lower percentage, while citrus and some herbal oils may require a higher percentage to achieve the desired scent. Additionally, the fragrance load can affect the performance of the candle. A higher fragrance load can result in a stronger scent throw, while a lower fragrance load may produce a more subtle aroma.
When adding fragrance oil to soy wax, it is recommended to start with a lower percentage and gradually increase until the desired scent is achieved. This is because too much fragrance oil can cause issues such as sweating, where excess oil is released during temperature changes or when the candles are exposed to heat. It can also affect the setting of the wax, causing it to become lumpy or curdled. Therefore, it is important to experiment with different percentages to find the optimal fragrance load for each specific fragrance.
To calculate the exact amount of fragrance oil needed for a soy wax candle, you can use a fragrance load calculator. These calculators take into account the finished candle size and the desired fragrance load percentage to determine the amount of wax and fragrance oil required. By using a calculator, you can ensure that your soy wax candles have the perfect fragrance load every time.

How much fragrance oil to add to soy wax
When making a scented candle, it is important to know how much wax your vessel holds and how much fragrance to use. The amount of fragrance oil you add to your candle depends on the type of wax, the type of oil, and your personal preference.
The standard recommendation for fragrance load is 6% to 8% of the total wax weight. This can be calculated by multiplying the volume of your jar by the percentage of fragrance load you want to use. For example, if you are making a 16 oz candle, your calculation would be 16 x 0.06 = 0.96 oz or 16 x 0.08 = 1.28 oz. Generally, the soy wax can contain up to 10% of the fragrance load, but you might face wicking issues.
It's important to note that the type of fragrance oil you use can affect the fragrance load. Oils with a stronger scent, like vanilla, can be used at a lower percentage, while lighter scents like citrus or herbal oils may need a higher percentage to be effective. The quality of the oil also matters; high-quality, concentrated oils will have a stronger scent, so less oil is needed.
The temperature at which you add the fragrance oil is also crucial. Fragrance oils have a flash point, which is the temperature at which the oil becomes combustible. The flash point varies depending on the type of oil, but it generally falls between 50-55 degrees Celsius. It's important to ensure that your wax temperature is below the flash point of the fragrance oil to avoid any safety hazards. The ideal pouring temperature for soy wax is between 155° - 165° F, but this may vary depending on the brand and blend of soy wax.
Allowing your candle to cure for several days before burning can help the soy wax and fragrance molecules to fully bind together. Cure times can range from a minimum of 3-4 days to a maximum of 2 weeks. Testing different cure times will help you determine the optimal hot throw for your candle.

The burn time of a soy wax candle with fragrance oil
The burn time of a candle depends on several factors, including the size of the wick, the density of the wax, and the type of wax used. Soy wax candles typically have a longer burn time compared to paraffin wax candles due to their higher melting point. However, the addition of fragrance oils can affect the burn time of soy wax candles.
Fragrance oils are added to soy wax candles to impart a pleasant scent. The amount of fragrance oil added can vary, typically ranging from 6% to 10% of the total weight of the wax. Some sources recommend starting with a lower percentage, around 6% or 1 oz of fragrance oil per 16 oz of wax, while others suggest a higher range of 8% to 10%. It's important to note that the type of fragrance oil used can also impact the burn time. Oils with a higher flashpoint, such as those containing vanilla, tend to have a higher density and require more heat to release their fragrance. On the other hand, citrus and herbal oils have a lighter density and may burn off too quickly, affecting the overall burn time of the candle.
The size of the wick also plays a crucial role in determining the burn time of a soy wax candle. A larger wick will create a deeper melt pool, causing the candle to burn faster. Conversely, a smaller wick may result in an insufficient melt pool, leading to a shorter burn time. Therefore, it is important to select an appropriately sized wick for the container and the type of wax used.
Additionally, the first burn of a soy wax candle is crucial to its overall burn time. If the candle is not allowed to reach a full melt pool during its initial burning, subsequent burns will be affected. This can result in tunnelling, where the candle burns down the centre, reducing its overall burn time.
In terms of actual burn times, small soy wax candles with fragrance oils typically burn between 20 and 30 hours, while medium-sized candles can last between 50 and 60 hours. Large candles can provide up to 90 hours of burn time. However, it's important to note that these burn times may vary depending on various factors, including the quality of the candle and the size of the melt pool.

The process of making a soy wax candle
Making soy wax candles is a fun and simple DIY project that can make wonderful gifts. Soy wax is a popular plant-based wax known for its excellent cold throw, long-lasting slow burn, and opaque white finish. Here is a step-by-step guide on how to make your own soy wax candles:
Prepare Your Work Area and Materials:
First, ensure you have a clean and flat work surface that can be used for several hours while your candles set and cool. Gather all the materials you will need, including soy wax flakes, candle containers (such as mason jars or tins), wicks, a heat source to create a double boiler (a saucepan and heat-proof container), a thermometer, fragrance oils or essential oils, dye (if desired), a pouring pitcher, and a wick bar or other tools to keep the wick centred (such as popsicle sticks or clothespins).
Melt the Soy Wax:
Create a double boiler by placing a heat-proof container in a pot of simmering water. Fill your pouring pitcher with the desired amount of soy wax flakes, typically around 1 pound (16 ounces or 454 grams) for two 8-ounce candles. Place the pitcher in the double boiler and heat the wax to 185°F (85°C). This temperature ensures that your fragrance oil will fully bind and mix with the wax without burning off.
Add Fragrance and Dye (Optional):
Once your wax has reached the desired temperature, it's time to add your chosen fragrance oil or essential oil. For 1 pound of soy wax, typically use between 0.96 ounces (27 grams) and 1.92 ounces (54 grams) of fragrance oil, depending on the desired fragrance load. This usually ranges from 6% to 10% of the total weight of the wax. Stir gently for about 2 minutes to ensure the oil is fully incorporated. If using dye, add it before the fragrance oil and stir until the desired colour is achieved.
Prepare the Wicks and Containers:
While your wax is melting, prepare your candle containers and wicks. Clean your containers with isopropyl alcohol and a paper towel. Centre a wick in each jar using a wick sticker or glue. If using a wick bar, secure it now to keep the wick centred and straight as the wax cools.
Pour and Set the Wax:
Once your wax has reached the desired temperature, colour, and fragrance load, carefully pour it into your prepared containers. Allow the wax to cool completely at room temperature. This may take a few hours. You can also let it harden for about 1-2 hours and then trim the wicks to 1/4 inch (6 mm) before allowing it to fully set.
Finishing Touches:
Once your candles have completely cooled and hardened, remove any wick bars or other centering tools and trim the wicks to the desired length if you haven't done so already. Add warning labels to the bottom of each candle, including safety tips and burning instructions. Your soy wax candles are now ready to be enjoyed or gifted!

The type of wax that holds the most fragrance
The type and amount of wax used in candle-making can vary depending on the candle maker's preference. Some of the most common types of wax used in candles include paraffin wax, soy wax, beeswax, and coconut wax.
Paraffin wax is derived from the oil industry's byproducts, making it less eco-friendly than other types of wax. It produces more soot than other types of wax, but it can be mitigated by keeping the wick properly trimmed. Paraffin wax candles typically have a fragrance load of around 6% to 8% of their total weight.
Soy wax is a more eco-friendly option than paraffin wax, offering a slow, steady burn. It is made from soybeans, but there are concerns about deforestation, fertilizers, and pesticides within the soybean industry. Soy wax can hold a higher fragrance load than paraffin wax, typically ranging from 8% to 10%.
Beeswax has a natural, pleasant scent of its own, so it is not commonly used with fragrance oils. It burns very well and releases negative ions, which are believed to neutralise pollutants and purify the air. Beeswax is commonly used for rolled candles, as the process requires less equipment.
Coconut wax is a newer option that is becoming increasingly popular due to its sustainability and clean burn. It is harvested from coconuts and does not contain any extra chemicals, making it completely natural and renewable. Coconut wax holds fragrances and colours well, making it a good choice for decorative candles.
Ultimately, the choice of wax depends on the candle maker's specific requirements, such as the type of candle, budget, desired fragrance strength, and environmental considerations.
