Understanding Soy Wax and Its Properties
Soy wax is a natural and renewable resource that has become a favourite among candlemakers for its eco-friendly properties. Unlike paraffin wax , which is a by-product of petroleum, soy wax burns cleaner and produces minimal soot, making it a healthier option for indoor air quality. Its molecular structure allows it to hold and release fragrance effectively, making it the go-to choice for scented candles.
One of the standout features of soy wax is its lower melting point, typically between 49°C to 82°C (120°F to 180°F), depending on the formulation. Most common blends melt between 54°C and 60°C (130°F and 140°F), making them easier to work with and perfect for crafting a variety of candle shapes. Additionally, soy wax blends seamlessly with fragrance oils and dyes , ensuring your final product is both aromatic and visually appealing.
Soy wax's biodegradable nature also means it’s kinder to the environment, breaking down naturally over time without leaving harmful residues. This sustainability aspect has contributed to its popularity among eco-conscious consumers. By leveraging the unique properties of soy wax, you can significantly enhance the quality and appeal of your candles, providing a superior sensory experience for your customers.
The Importance of Temperature in Candle Making
- Temperature control is a vital aspect of candle making that directly influences quality, appearance, and performance. The temperature at which you add fragrance oils can determine scent throw, longevity, and the overall aroma of the candle.
- Adding fragrance at too high a temperature can cause it to evaporate, resulting in a weaker scent. Conversely, if it's added too low, the fragrance may not fully integrate, leading to uneven distribution and affecting burn quality. Therefore, mastering temperature control is essential for achieving a consistent and high-quality scent throw in your soy candles.
- Temperature also impacts the candle's appearance. Incorrect temperatures can cause issues like frosting, air bubbles, or uneven surfaces, detracting from the overall aesthetic. By getting a handle on temperature control, you can ensure your candles not only smell delightful but also look polished and professional.
Ideal Temperature Range for Adding Fragrance to Soy Wax
For the best results when making scented soy candles, it’s recommended to add fragrance oil when the wax is heated to around 80℃ - 85℃ (175°F to 185°F)*.
This range is ideal because it allows the fragrance oil to bind effectively with the wax, ensuring a robust and consistent scent throw. Heating the wax within this range guarantees that the fragrance oil is fully integrated, preventing any separation or uneven distribution.
*Whilst this temperature is a general rule of thumb, many makers swear by adding the oil in at a much lower temperature, usually between 60℃ - 65℃ (140°F - 149°F). We suggest trying both temperature ranges to see which one works best for you.
How Temperature Affects Scent Throw
Scent throw is the ability of a candle to disperse its fragrance throughout a space, and there are two types: cold throw and hot throw. Cold throw is the scent emitted when the candle is unlit, while hot throw is the fragrance released when it’s burning. The temperature at which you add fragrance oil significantly influences both cold and hot throw!
When added at the ideal temperature, the fragrance oil binds effectively with the soy wax, ensuring even distribution of scent molecules. This results in a strong cold throw, meaning the candle emits a pleasant aroma even when unlit. A good cold throw is essential, as it is what first attracts you to a candle!
Hot throw is just as important, as it determines the fragrance's strength and reach when the candle is burning. Adding fragrance oil at the correct temperature ensures consistent and effective scent release, creating a warm and inviting atmosphere.
Tips for Measuring and Controlling Temperature
Accurate temperature measurement is key to successful candle making. Using a reliable thermometer is essential to ensure the wax reaches the correct temperature before adding fragrance oil.
Digital thermometers are highly recommended for their precision and ease of use, providing quick and accurate readings for close monitoring.
When heating soy wax, do so gradually and evenly. A double boiler or dedicated wax melter can help achieve a consistent temperature without overheating the wax. Avoid direct heat sources, like stovetop burners, as they can cause uneven heating and potential scorching.
Gently stirring the wax as it heats can also help distribute the temperature evenly and prevent hot spots.
Once the wax reaches the ideal temperature, add the fragrance oil slowly and stir thoroughly to ensure it’s evenly distributed throughout the wax.
Common Mistakes to Avoid When Adding Fragrance
Incorrect Amount of Fragrance Oil: Using too much can overwhelm the wax, causing separation or poor burn performance, while too little results in a weak scent throw. Following recommended usage rates for your specific fragrance oil and wax combination is crucial.
Improper Mixing: Failing to stir fragrance oil thoroughly can lead to uneven distribution and inconsistent scent throw. This could also pose a potential fire hazard if pockets of oil have formed within the candle! It’s essential to mix the fragrance and wax well to ensure uniform distribution.
Types of Fragrance Oils and Their Recommended Temperatures
Fragrance oils come in a wide range of scents, each with unique properties and recommended temperature ranges for optimal performance. Understanding these differences is key to achieving the best results in your scented soy candles.
Floral and citrus oils are generally more volatile and should be added at the lower end of the recommended temperature range, around 60℃ - 70℃ (140°F to 158°F).
This helps preserve delicate scent molecules for a strong and consistent aroma.
Woody and spicy fragrance oils, being less volatile, can withstand higher temperatures and can be added at the higher end of the range, around 82℃ - 85℃ (180°F to 185°F).
This allows richer, more robust scent molecules to blend seamlessly with the soy wax for a deep and long-lasting aroma.
Adjusting the temperature at which you add fragrance oil can influence scent throw and overall aroma. Start by making small test batches, heating soy wax to different temperatures within the recommended range and adding the same fragrance oil to each batch. This will help you compare scent throw and performance at various temperatures and determine the optimal temperature for each fragrance!
The Role of Other Ingredients in Scent Release
While temperature is crucial, other ingredients also play a significant role in scent release. The type of wick can influence burn rate and scent release. A too-small wick may not create enough heat to melt the wax fully, while a too-large wick may burn too quickly, causing scent evaporation. Choosing the right wick size is vital for balanced scent throw.

The quality of the fragrance oil itself is another important factor to consider. High-quality fragrance oils are specifically formulated for candle making and are designed to withstand the heat and blend effectively with the wax.

Frequently Asked Questions
How much fragrance oil should I use in soy wax?
A standard guideline is to use 6% to 10% fragrance oil based on the wax weight. Experiment to find the percentage that yields the best scent throw. It often helps to experiment a bit to determine the percentage that yields the best scent throw. Make sure to use our handy scent load calculator to work out exactly how much wax and oil to use for your chosen ratio.
How does the viscosity of fragrance oil affect scent load?
- Thicker Oils: May not blend easily, leading to uneven distribution. Higher temperatures might be needed for proper incorporation, and lower scent loads may be necessary to avoid separation.
- Thinner Oils: Generally mix well and can support higher scent loads without negatively impacting performance.
My candle emits a fuel-like aroma when pouring; what went wrong?
Citrus-heavy fragrances can produce a fuel-like smell if added at too high a temperature. Adding them at 60°C or lower helps prevent this.
What’s flashpoint, and does it matter when adding fragrance oils?
The flashpoint is the temperature at which a fragrance oil can combust if exposed to an open flame or spark. Adding fragrance oil to wax above the oil's flashpoint will not cause it to combust. At room temperature, there is no cause for concern.
Do low flashpoint fragrances burn off?
No, as long as the fragrance is added to the wax and poured promptly. Avoid repeatedly cooling and reheating batches; limit your batch size to what can be poured right away.
