Essential oils can be added to candles to bring benefits to the mind and body during aromatherapy and wellness practices. However, it is important to know when to add essential oils to candles as they are highly flammable and can pose a fire hazard if not used correctly. The wax should be heated to the right temperature before adding essential oils, as overheating can cause the oils to evaporate too quickly. The wax should then be stirred gently for a few minutes to ensure the oil is fully incorporated.

What You'll Learn
Use candle-making fragrance oils, not essential oils
While essential oils can be used in candles, there are several reasons why fragrance oils are a better option. Firstly, essential oils are not designed for combustion. Many essential oils are highly flammable and can add a serious fire hazard to your candle. Some essential oils can even be toxic when burned. Additionally, essential oils are not formulated to mix into candle wax, which means they may not blend properly and could leave a greasy residue on your candles.
Fragrance oils, on the other hand, are specifically designed for candle-making. They are formulated to bind to the wax, creating a stronger and longer-lasting scent. Fragrance oils also tend to be much more affordable than essential oils, with fragrance oils available for less than $2 per ounce, while even the cheapest essential oils typically cost more than $5 per ounce.
Furthermore, essential oils are not always heat-stable and can evaporate quickly when exposed to heat. This means that candles made with essential oils may lose their scent more rapidly than those made with fragrance oils. Fragrance oils are also more sustainable than essential oils, as it takes a large amount of plant material to produce a small quantity of essential oil. For example, it takes around 50 pounds of eucalyptus to create just one pound of eucalyptus oil, and a staggering 10,000 pounds of roses to produce one pound of rose oil.
When adding fragrance oil to your candle, it is important to do so at the right temperature. For soy and paraffin wax, the recommended temperature is 180-185°F, while for palm wax, it is 200-205°F. Stirring the mixture for several minutes is also crucial to ensure that the oil is fully incorporated into the wax.
In summary, while it is possible to use essential oils in candle-making, fragrance oils are a safer, more effective, and more cost-efficient option. By following the recommended guidelines for adding fragrance oil to your candles, you can create a high-quality, strongly scented candle that is safe to burn.

Add oil when wax is 180-185°F for soy/paraffin wax
Adding essential oil to your candle at the right temperature is crucial to ensuring your candle has a strong, evenly distributed scent. For soy wax, it is generally recommended to add essential/fragrance oil at a temperature of around 180° - 185°F. This temperature range allows the fragrance to mix thoroughly with the wax, ensuring a consistent scent throughout your candle.
Soy wax has a high fragrance load capability (10%+) and can retain fragrance more effectively than other waxes. It encapsulates and traps fragrance oil molecules during the bonding process and does not readily release or evaporate fragrance. However, it is important to monitor the temperature closely, as heating soy wax above 190°F for an extended period can compromise its integrity, leading to a less effective candle.
The amount of essential oil you add is also important. For a strong scent, add about 1 ounce of essential oil per pound of wax. If you prefer a milder fragrance, use around 0.5 ounces per pound. Since essential oils are more concentrated than fragrance oils, staying on the lower end of the range (6-10% fragrance oil relative to the weight of the wax) is typically recommended.
When adding essential oil, make sure to stir gently but continuously for 1-2 minutes. This helps the fragrance bind properly with the wax, which is crucial for achieving a strong scent throw and preventing the fragrance from separating or evaporating too quickly. It is also important to let your candle cure before lighting it. This allows the soy wax and fragrance molecules to fully bind together. Cure times are recommended at a minimum of 3-4 days and a maximum of 2 weeks.

Stir for several minutes to prevent oil settling
Adding fragrance oil to your candle at the right temperature is crucial to help it bind to the wax, which will give you a stronger scent throw. Stirring the mixture for several minutes is also important to prevent the fragrance oil from settling at the bottom of the wax, which can result in a weak scent throw. Stirring for a short amount of time can keep your fragrance oil from binding to the wax.
It is recommended to stir gently for 1-2 minutes to ensure that the oil is fully incorporated with the wax. Be sure not to stir too fast, as this can introduce air bubbles, leading to imperfections in your candles. For long-lasting candle scents with essential oils, it's important to use the right amount of fragrance and mix thoroughly.
The percentage of oil to the weight of the wax is called the fragrance content. Although the exact percentages vary depending on the type of wax and the manufacturer’s recommendations, the usual range is between 6 and 10%. Accurate measurement is important because using too much fragrance oil can cause wick clogging, irregular burning, or perspiration (oil leaking from the surface), while using too little results in a faint smell.
Each wax has a recommended fragrance oil load, and going beyond that limit can cause the fragrance oil to separate from the wax, creating ugly "gooey" spots and becoming a potential fire hazard. Too much fragrance can also cause the wick to clog, which will make your candle have a weak scent throw.

Don't add too much oil to avoid a clogged wick
Adding essential oils to candles can be dangerous, and one of the most important things to keep in mind is not to add too much oil. While it may be tempting to add more oil to achieve a stronger scent, this can lead to a clogged wick, which will negatively affect the performance of your candle.
When too much fragrance oil is added to the wax, it can separate and create "ugly gooey spots". These spots are not only unsightly, but they can also clog the wick. A clogged wick will result in a weak scent throw, and your candle may struggle to burn properly.
To avoid this issue, it is important to use the correct amount of essential oil. Each wax has a recommended fragrance oil load, and it is important not to exceed this limit. It is recommended to start with a low load of oil and gradually increase if needed. Always measure the oil by weight, as essential oils vary in density, and this is the best way to ensure accuracy.
In addition to the risk of wick clogging, adding too much essential oil can also increase the risk of fire. Essential oils are highly flammable and have a low flashpoint (the temperature at which they become flammable). Adding too much oil can increase the risk of ignition, especially if the oil is incorrectly dosed or the combustion temperature becomes too high. Therefore, it is crucial to follow safety guidelines when adding essential oils to candles and always use oils specifically designed for candle making.

Use a double boiler for precise temperature control
Candle-making is an art, and one that requires precision and patience. One of the most important steps in the process is adding the essential oil, as this will give your candle its unique scent. But when is the best time to add this oil, and how can you ensure you don't ruin your creation?
Using a double boiler is a popular method for candle makers, as it offers precise temperature control. This is crucial when adding essential oils, as they need to be combined with the wax at just the right temperature to ensure a successful blend. The double boiler method is a simple, cost-effective way to achieve this, and it's a great option if you don't have access to fancy equipment or a lot of supplies.
A double boiler is a two-pot setup. The larger pot contains simmering water, while a smaller pot fits inside it to melt the wax gradually. This gradual melting is key to success, as it prevents scorching by limiting how hot the wax can get. With a double boiler, the water heats up first and then gently heats the wax, ensuring an even melt. This is much safer than heating wax directly in a pot over a flame, which can cause the wax to get too hot and burn.
The double boiler method is also more energy-efficient than using a single pot. While a double boiler typically uses a high heat setting, a single pot only needs a low to medium setting. This means you'll use less energy overall, and it's easier to cool the wax down if it gets too hot. Plus, with a double boiler, you don't have to worry about the wax getting too hot and damaging your skin.
So, if you're looking to add essential oils to your candles, the double boiler method is a great option. It gives you precise temperature control, helping you create beautifully scented candles without the risk of burning or scorching your precious creations.
