What You'll Learn
Choosing the right perfume or fragrance oil
Type of Fragrance
It is important to choose fragrances that are specifically designed for candles. Traditional perfumes or fragrances may contain ingredients that don't burn properly. Candle fragrances are available in synthetic or natural options, allowing you to create unique scents. However, essential oils are not suitable for perfuming wax creations as they need to be diluted with a carrier oil.
Flashpoint
The flashpoint of a fragrance is a critical factor to consider. It refers to the temperature at which the fragrance will evaporate or burn. Different fragrances have different flashpoints, so refer to the safety data sheet of your chosen fragrance to determine this. As a general rule, add fragrances with a flashpoint under 130°F to wax at 130°F. For flashpoints between 130°F and 180°F, add the fragrance at its flashpoint. If the flashpoint is above 180°F, add it to the wax at 180°F.
Fragrance Load
Determining the correct amount of fragrance to add to your wax is essential for achieving the desired scent strength. Most waxes can hold up to 12% fragrance, but the optimal range is between 6% and 10%. To calculate the amount of fragrance needed, consider the maximum fragrance load of your wax and the weight of your candle. For example, if you're using 10 ounces of soy wax with a 10% fragrance load capacity, you would need 1 ounce of fragrance.
Density
The density of your fragrance represents the total weight of the perfume for the same volume. This can vary between different perfumes, so it's important to refer to the safety data sheets to find the density at specific temperatures. Knowing the density helps you consolidate your dosage, especially when creating large batches of scented candles.
Stirring and Settling
Once you've added the fragrance to the wax, stir the mixture thoroughly to ensure even distribution. Stirring for a short time may result in the fragrance oil settling at the bottom, leading to a weak scent. After stirring, allow the scented wax to settle for at least 3-4 hours before burning the candle. This gives the fragrance time to bond with the wax, ensuring optimal diffusion when the candle is lit.

Understanding the characteristics of your fragrance
Fragrance Notes
Fragrance notes refer to the layers of scent that are revealed as the candle burns. These notes can be categorised into three types: top, middle, and base notes. Top notes are the initial impression of the candle, typically light and fresh, setting the tone for the fragrance experience. Middle notes form the heart of the fragrance and emerge after the top notes dissipate. They are often floral or spicy, providing the main character of the scent. Base notes are the foundation of the fragrance and are rich and long-lasting. Understanding these notes will help you create a well-rounded and captivating scent profile for your candle.
Scent Families or Categories
Scent families or categories provide a broad framework for understanding fragrances. The four main categories are floral, spicy, earthy, and light fragrances. Floral scents include roses, lilacs, lavender, or jasmine, often evoking a sense of femininity and relaxation. Spicy scents, such as cinnamon, amber, or vanilla, are reminiscent of the Eastern world. Earthy notes like cedar, leather, or peat are typically associated with masculinity. Light fragrances include rain, linen, or citrus, offering a refreshing and uplifting experience.
Source of Fragrance
Fragrances can be derived from two main sources: essential oils and fragrance oils (also known as aromatic chemicals). Essential oils are natural extracts from plants and are often prized for their potential health and therapeutic benefits. However, they can be more expensive and may not provide the desired scent throw when used alone. Fragrance oils, on the other hand, are manufactured in laboratories specifically for use in candles and other scented products. They offer a stronger and longer-lasting scent throw, making them a popular choice among candle makers.
Dosage and Calculations
Determining the correct amount of fragrance to add is critical to achieving the desired olfactory result. Two common methods for calculating dosage are based on total weight (wax + fragrance) and wax weight only. The first method simplifies recipes, while the second method provides a more precise fragrance concentration in the wax. Understanding these calculations will help you dose your fragrances accurately and create high-quality scented candles.
Density and Flash Point
Understanding the physical characteristics of your fragrance, such as density and flash point, is essential for proper dosing and ensuring the fragrance binds effectively with the wax. The flash point, in particular, is critical to know, as adding fragrance when the wax is too hot can cause the scent to dissipate or "burn off."
By carefully considering these characteristics of your fragrance, you can create scented candles that not only appeal to the sense of smell but also enhance the overall candle-burning experience.

How much perfume to add
The amount of perfume you add to candle wax depends on several factors. Firstly, it is important to understand the characteristics of your fragrance, including its density and flashpoint. The density of a perfume represents its total weight for the same volume. The weight can differ for perfumes with the same capacity. Knowing the density allows you to consolidate your dosage, especially during large productions.
The flashpoint is the temperature at which the fragrance oil becomes combustible when exposed to a spark or flame. The flashpoint of the fragrance oil will determine the temperature at which it should be added to the wax. Generally, the warmer a fluid is, the more vapours it releases into the atmosphere, while cooler liquids hold their vapours better. Therefore, the flashpoint will influence the scent throw of your candle.
The type of wax used will also determine the amount of fragrance that can be added. Most waxes will not hold more than 12% fragrance. Soy wax, for example, can hold up to 10% fragrance. Store-bought candles typically contain an average of about 6% fragrance, while premium candles contain up to 10%. To optimise scent throw and maintain candle stability, it is recommended to use between 6 to 10% fragrance in your candle mixture.
To calculate the amount of fragrance needed, you can use the formula: percentage of fragrance x weight of wax (in ounces) = weight of fragrance (in ounces). For example, if you are using a soy wax that can hold up to 10% fragrance and you are making a 10-ounce candle, you would need to use 1 ounce of fragrance: 0.10 (percentage) x 10 oz (wax weight) = 1 oz (fragrance amount).
It is important to add the fragrance when the wax is fully expanded but not too hot, as this can cause the fragrance to degrade and lose its throw. The ideal temperature range for adding fragrance to wax is between 175°F to 185°F. Additionally, the fragrance should be added at a temperature below its flashpoint to avoid combustion.
Another strategy to enhance the olfactory result is to mix the perfume with isopropyl myristate, which increases its heat threshold and allows for experimentation with different perfume combinations.

When to add the perfume
When adding perfume to candle wax, there are several important factors to consider to ensure optimal results. Firstly, it is crucial to understand the characteristics of your chosen fragrance, including its density and flashpoint. The flashpoint of a fragrance is the temperature at which it will ignite, and it varies depending on the specific perfume being used. Therefore, it is essential to refer to the safety data sheet of your chosen fragrance to determine its flashpoint before proceeding.
In general, when adding fragrance to candle wax, it is recommended to do so when the wax is molten and has reached a suitable temperature. This temperature range can vary depending on the type of wax and fragrance being used. For most waxes, the recommended temperature range for adding fragrance is between 175°F to 185°F (80°C to 85°C). However, it is important to ensure that the wax is not heated above its flashpoint, as this can degrade the fragrance and reduce its effectiveness.
It is also important to consider the amount of fragrance being added to the wax. As a rule of thumb, fragrances should typically comprise between 6 to 10 per cent of the total candle mixture. Adding too much fragrance can result in syneresis, or "bleed", where excess oil separates from the wax and forms liquid drops on the surface of the candle. This can be avoided by understanding the maximum fragrance load of the wax being used and adding the appropriate amount of fragrance.
Another strategy to enhance the heat resistance of your chosen perfume is to mix it with isopropyl myristate, a substance that increases the perfume's heat threshold. This allows for greater flexibility in creating unique perfume combinations without worrying about the fragrance degrading due to high temperatures. However, it is still crucial to integrate the fragrance below its flashpoint, even when using additives like isopropyl myristate.
Finally, once the fragrance has been added to the molten wax, it is important to allow adequate time for the fragrance to settle and bond with the wax. This process can take several hours, and it ensures that the fragrance is properly absorbed and diffused when the candle is burned. After adding the fragrance, remove the wax from the heat source and allow it to cool and harden completely before proceeding with the next steps of candle-making.

Stirring techniques
When stirring perfume into candle wax, there are several important techniques to keep in mind to ensure a successful outcome. Here are some detailed instructions for stirring techniques:
First, it is crucial to determine the correct amount of fragrance to add to the wax. Each wax type has a maximum fragrance load, and exceeding this limit can cause the oil to separate from the wax, resulting in a weak scent or even a potential fire hazard. As a rule of thumb, use between 6 to 10 percent of fragrance oil in your wax mixture. This percentage can be calculated based on the weight of your wax. For example, if you are using 10 ounces of soy wax that can hold up to 10 percent fragrance, you would need 1 ounce of fragrance oil.
Next, fragrance flashpoint plays a vital role in the stirring process. The flashpoint is the temperature at which the fragrance can be safely added to the wax without degrading or losing its scent. Different fragrances have different flashpoints, so it is important to refer to the safety data sheet of your chosen fragrance. Generally, if the flashpoint is under 130°F, add the fragrance at 130°F. If the flashpoint is between 130°F and 180°F, add it at the fragrance flashpoint. For flashpoints above 180°F, add the fragrance at 180°F.
Once you've determined the correct fragrance load and flashpoint, it's time to start the stirring process. Begin by heating your wax to the desired temperature, typically between 175°F to 185°F, or specifically 185°F for soy wax. Then, add the fragrance oil and remove the mixture from the heat source. Gently stir the mixture for at least 1 to 2 minutes to ensure the fragrance binds properly with the wax. Avoid stirring for a shorter amount of time, as it can cause the oil to settle at the bottom, resulting in a weak scent.
After stirring, allow the scented wax to cool down before pouring it into your prepared candle containers. The recommended cooling temperature is around 135°F (57.2°C). During the cooling process, the fragrance will settle and bond with the wax, ensuring optimal scent diffusion when the candle is burned. It is recommended to wait at least a week before lighting your scented candle to allow the fragrance to reach its full potential.
Additionally, you can experiment with mixing your chosen perfume with a substance called isopropyl myristate to increase its heat threshold. This allows you to create unique perfume combinations and enhance the olfactory result. However, always refer to the safety data sheet to determine the flashpoint of your fragrance mixture.
