What You'll Learn

Calculating fragrance load
The fragrance load of a candle is the quantity of fragrance oil applied to the candle wax. It is important because it determines the strength of the aroma when the candle is burning. If too little fragrance oil is used, the candle may have a weak aroma. On the other hand, using too much fragrance oil might result in unpleasant smells and issues like curdling or sweating candles.
The recommended fragrance load for an 8 oz candle typically falls between 5% to 10% of the weight of the wax used in the candle. This range ensures a pleasant, balanced scent without overwhelming the candle. However, the recommended fragrance load can vary depending on factors such as the type of wax and the potency of the fragrance oil. For example, soy wax candles generally have a lower fragrance load compared to blended waxes like coconut soy wax, which can often handle up to a 12% fragrance load for a very strong scent.
To calculate the fragrance load, you need to determine the weight of the wax in ounces and multiply it by the desired fragrance load percentage. For example, if you are using 8 oz of wax and want a 7% fragrance load, you would multiply 8 by 0.07, resulting in 0.56 oz of fragrance oil needed. It's important to remember that accuracy is key when measuring both the wax and fragrance oil. Using scales can help ensure consistency and accuracy in the candle-making process.
It's also worth noting that the flashpoint of the fragrance oil should be considered. The flashpoint is the temperature at which the oil will ignite if exposed to an open flame, so choosing oils with a suitable flashpoint for candle-making is important. Additionally, understanding the difference between weight ounces and fluid ounces is crucial, as fragrance load calculations are based on weight rather than fluid volume.
Calculating the correct fragrance load for your candle can be a delicate process, and it may take some experimentation to find the perfect balance for your specific candle-making setup.

Different types of wax
The amount of fragrance oil to add to an 8 oz candle depends on the type of wax used. The recommended fragrance load typically falls between 5% to 10% of the weight of the wax used in the candle. For example, for a 10% fragrance load, you would need 7.27 oz of wax and 0.73 oz of fragrance oil.
Paraffin wax is one of the most popular types of wax for highly scented candles. It is known for its affordability and versatility, as it comes in various melting points, allowing candlemakers to create everything from votives to pillars and container candles. However, it doesn't burn as cleanly as other waxes and can cause the release of soot and other chemicals into the air.
Soy wax is a popular middle-ground choice for candles, offering a slow, steady burn that makes it a great value. It is more eco-friendly than paraffin wax but has some concerns about deforestation, fertilizers, and pesticides within the soybean industry and production process. Soy wax works best in candles that come in vessels such as tealights and votives.
Coconut wax is a newer option that is becoming increasingly popular for its luxurious properties. It is biodegradable, burns slowly, and holds fragrance well, providing an excellent scent throw. Its softness and low melting point make it suitable to mix with other waxes, such as beeswax or soy, to create a wax blend.
Rapeseed wax is a natural, sustainable, and vegan-friendly wax derived from rapeseed oil. It burns cleanly, with minimal soot production, and is a good option for blending with other waxes to achieve the desired consistency.
Palm wax is unique for its ability to create stunning crystalline and feathered textures, making it a great choice for decorative freestanding candles like pillars. It burns slowly and cleanly but contributes to the deforestation of palm trees.
Gel wax allows for transparency, making it perfect for novelty or artistic candles with embedded objects or layered designs. It has a higher melting point than wax candles, but it has a propensity to overheat, causing thin glass vessels to crack or break. It is not a natural or biodegradable option.

Potency of fragrance oil
The potency of fragrance oil in candles is an important consideration when candle-making. The quantity of fragrance oil added to the candle wax is known as the fragrance load, and this determines the strength of the aroma when the candle is burning. If too little fragrance oil is added, the candle's scent will be weak and faint. However, adding too much fragrance oil can result in an overpowering scent and cause issues such as curdling or sweating in the candle.
The recommended fragrance load for an 8 oz candle typically falls between 5% and 10% of the weight of the wax used. This range ensures a pleasant and well-balanced scent. However, it's worth noting that the ideal fragrance load can vary depending on factors such as the type of wax and the potency of the fragrance oil. For example, soy wax candles usually have a lower fragrance load compared to blended waxes like coconut soy wax, which can handle up to 12% fragrance load for a stronger scent.
The flashpoint of the fragrance oil is another crucial factor to consider. The flashpoint refers to the temperature at which the fragrance oil will ignite if exposed to an open flame. Choosing fragrance oils with a suitable flashpoint for candle-making is essential for safety reasons. Additionally, the temperature at which the fragrance oil is added to the wax can impact its potency. If the wax is too hot or too cold, it can affect the fragrance's strength, resulting in a candle with little to no scent.
To calculate the amount of fragrance oil needed for an 8 oz candle, you should first determine the weight of the wax in ounces. Then, multiply the weight of the wax by the desired fragrance load percentage. For example, if you're using 7% as your fragrance load, you would multiply the weight of the wax by 0.07 to find the amount of fragrance oil needed in ounces. Accuracy is crucial when measuring both the wax and the fragrance oil to ensure consistent results.
The type of fragrance oil used also plays a role in determining the fragrance load. Different fragrance oils have varying strengths and capacities for scent throw. Some oils may require a higher fragrance load to achieve the desired scent intensity. It's recommended to experiment with different oils and fragrance loads to find the perfect balance for your candles.
