Creating scented candles is a delightful craft that allows you to fill your home with beautiful, aromatic fragrances. However, getting the fragrance just right can be tricky. The type of wax, the size of the candle, and the potency of the oil all play a role in determining the right amount of oil to use. For example, the recommended fragrance load for an 8 oz candle typically falls between 5% to 10% of the weight of the wax used, but this can vary depending on the type of wax and the desired scent strength.

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 to calculate this accurately as it determines the strength of the aroma when the candle is burning. Too little fragrance oil will result in a weak aroma, while too much can cause unpleasant smells and issues such as curdling or sweating.
The recommended fragrance load for an 8 oz candle typically falls between 5% to 10% of the weight of the wax used. This range ensures a pleasant, balanced scent without being overwhelming. However, it's important to note that 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 handle up to 12% fragrance load for a stronger scent.
To calculate the amount of fragrance oil needed, 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 are using 7 oz of wax and want a 10% fragrance load, you would multiply 7 by 0.10, resulting in 0.7 oz of fragrance oil needed.
It's important to use a scale to measure both the wax and fragrance oil accurately. Additionally, remember that you are working with weight ounces, not fluid ounces. The flashpoint of the fragrance oil, or the temperature at which it will ignite when exposed to an open flame, should also be considered to ensure safety.
The type of wax and fragrance oil, as well as personal preferences for scent strength, will influence the final fragrance load. Beeswax and soy wax are popular choices for their ability to hold scent and slower burn rates. Essential oils are ideal for a natural approach, while fragrance oils offer a wider range of scents. Experimentation is often needed to find the right balance, as too much oil can affect the candle's performance and even create a fire hazard.

Type of wax
The type of wax used in candle-making plays a crucial role in determining the fragrance load, or the amount of fragrance oil added to the wax. Different types of wax have varying capacities for holding fragrance oils, and some may require a higher fragrance load to achieve the desired scent strength.
One of the most popular types of wax for candle-making is soy wax. Soy wax candles generally have a lower fragrance load compared to other types of wax. For example, blended waxes like coconut soy wax can often handle a higher fragrance load, up to 12%, resulting in a very strong scent throw.
The density of the wax is another important factor to consider when determining the fragrance load. Wax typically has an average gravity of 0.86, meaning it is 86% the density of water. However, different types of wax can have different densities, which will affect the weight and volume of the wax when melted. This, in turn, will impact the amount of fragrance oil that can be added.
When selecting a type of wax for candle-making, it is important to refer to the manufacturer's recommendations for the maximum fragrance oil load percentage. This information can usually be found on the product packaging or in the product description if purchased online. It is crucial not to exceed this maximum fragrance load, as it can negatively impact the structure of the candle.
Additionally, it is worth noting that just because the wax can hold a certain percentage of fragrance oil, it doesn't mean that amount is necessary. Testing different quantities of fragrance oil is essential to establish the most effective fragrance load for the desired scent throw. The perfect ratio of fragrance oil to wax will ensure a balanced aroma without compromising the composition of the candle.

Type of oil
The type of oil you use for your 8 oz candle depends on the type of scent you want to create and the benefits you want to offer your customers.
Fragrance oils are a popular choice for candle-making. They are available in a wide range of scents, from floral and fruity to warm and woody. You can also find fragrance oils that are free from phthalates and other toxins, adhering to safety and purity standards. These oils are versatile and can be used in soaps, lotions, and other skincare products. When selecting a fragrance oil, consider the desired strength of the scent, the environment in which the candle will be used, and its compatibility with the wax. For an 8 oz candle, the recommended fragrance load typically falls between 5% to 10% of the weight of the wax used.
Essential oils are another option for candle-making. Derived from plants, they are 100% natural and highly concentrated. In addition to fragrance, essential oils can positively influence mood and well-being. Some essential oils that work well in candles include lavender, patchouli, geranium, and cedarwood. It is important to note that essential oils can be more expensive than fragrance oils due to the amount of natural material required to produce them. Additionally, the odour of essential oils can change when exposed to heat, so testing is crucial.
The type of wax and the desired scent strength will also influence the type and amount of oil you choose. For example, soy wax candles typically have a lower fragrance load compared to blended waxes like coconut soy wax. To calculate the amount of fragrance oil needed, multiply the weight of the wax by the desired fragrance load percentage.

User preference
The number of drops of oil for an 8 oz candle depends on several factors, including the type of wax, the type of oil, and the user's preference for the ideal scent.
The type of wax used in the candle plays a significant role in determining the fragrance load. Different waxes have varying capacities for holding fragrance. For example, soy wax and beeswax are known for their ability to hold scent and slower burn rates, resulting in a longer-lasting fragrance. On the other hand, blended waxes like coconut soy wax can often handle a higher fragrance load, up to 12%, resulting in a stronger scent throw.
The type of oil used, whether it is a fragrance oil or an essential oil, also impacts the recommended amount. Fragrance oils are synthetic and offer a wider range of scents, while essential oils are natural and provide therapeutic benefits. The potency of the oil is crucial, as a more potent oil will require less quantity to achieve the desired scent strength.
To calculate the amount of fragrance oil needed, determine the weight of the wax in ounces and multiply it by the desired fragrance load percentage. For example, if you want a 7% fragrance load for your 8 oz candle, you would multiply 8 by 0.07, resulting in 0.56 oz of fragrance oil needed.
It is worth mentioning that there is a certain amount of trial and error involved in achieving the perfect scent. Some people experiment with soaking the wick in a few drops of oil before placing it into the candle jar to enhance the fragrance. Others focus on the type of oil, opting for essential oils with base notes that tend to work well for creating a stronger scent. Ultimately, the user's preference for scent strength and type of oil will guide the number of drops needed for their 8 oz candle.

Safety considerations
Safety should be a top priority when making candles with essential oils. Here are some detailed safety considerations to keep in mind:
Flashpoint and Heating
Essential oils have a lower flashpoint than fragrance oils, meaning they can ignite at lower temperatures. When heated, their chemical composition can degrade, reducing the strength of the scent. This can be frustrating if you are using expensive oils. More importantly, it increases the risk of accidents, including the risk of ignition if the combustion temperature becomes too high. Therefore, it is crucial to choose oils with a suitable flashpoint for candle-making and never heat essential oils directly. Always mix them with wax before heating.
Research Oil Safety
Some essential oils can release carcinogenic, mutagenic, or reprotoxic substances (CMR) when heated to high temperatures. Therefore, it is important to research which oils are safe to use in candles. For example, soy wax and beeswax can tolerate stronger scents, while paraffin wax should be used with more delicate oils. Citrusy scents can be overpowering if not used in the right quantities.
Amount of Oil
Using too much oil can cause the candle to burn too quickly, creating a potential fire hazard. It can also lead to an overwhelming scent and cause problems like curdling or sweating in the candle. On the other hand, using too little oil can result in a faint fragrance that burns out quickly. It is recommended to experiment with different ratios to find the right balance for your candle. Calculations based on the weight of the wax and the desired fragrance load can help determine the right amount of oil to use.
Candle Care
Once your candle is made, it's important to follow general candle safety guidelines. Never leave a burning candle unattended, and keep it away from flammable items. Do not leave candles lit overnight. Always follow the recommended guidelines for candle usage to ensure a safe and enjoyable experience.
