As consumers become more aware of the toxins in cleaning agents, air fresheners, and personal care products, essential oils have emerged as a popular natural alternative. They are a concentrated liquid of compounds extracted from plants, typically produced through distillation with water or steam. While some companies advertise candles made with essential oils, this is often a marketing tactic, as candles made with 100% essential oils are often very lightly scented and expensive. Furthermore, essential oils may not be suitable for candle-making due to safety concerns and poor olfactory performance. They have a low flash point, or temperature at which they become flammable, and can increase the risk of accidents. They also tend to lose their scent quickly when exposed to heat and can be difficult to mix with waxes like soy or beeswax. As a result, safer alternatives, such as fragrances designed for diffusion in candles, are often recommended for candle-making.

Risks of using essential oils in candles
While essential oils may seem harmless, they are not risk-free. Using essential oils in candles can introduce several risks, and it is important to be aware of these dangers before attempting to make your own scented candles at home.
One of the primary risks associated with using essential oils in candles is their low flash point. The flash point is the temperature at which a substance becomes flammable, and essential oils tend to have a low flash point, making them more susceptible to ignition when used in candles. This can increase the risk of accidents, especially if the oils are incorrectly dosed or if the combustion temperature becomes too high.
Essential oils can also be challenging to work with due to their poor diffusion and uneven fragrance distribution. They may lose their scent quickly when exposed to heat, requiring frequent refills without ensuring consistent diffusion. This can be frustrating, especially given the high cost of essential oils. Additionally, heat can alter the chemical composition of some oils, resulting in an unpleasant odor instead of the desired relaxing experience.
Another concern is the potential release of CMR substances. CMR stands for Carcinogenic, Mutagenic, or Reprotoxic, and some essential oils can release these harmful substances when heated to high temperatures. This poses a significant health risk that should not be overlooked.
Furthermore, essential oils may not mix well with certain types of wax, such as soy or beeswax. This can affect the texture and burn of the candle, compromising its effectiveness and aesthetic appeal. To achieve a sufficiently strong fragrance, a large quantity of essential oil may be needed, which can be costly.
While some sources claim that essential oils are safe for candle making if used in the correct proportions, it is crucial to thoroughly research the specific essential oil and its recommended usage before adding it to a candle. It is also important to use the right equipment, such as a double boiler and thermometer, to ensure precise temperature control and prevent overheating.

Safer alternatives to essential oils
While essential oils are commonly used in candles, they may not be the safest option. The use of essential oils in candles can increase the risk of accidents, including ignition if the oils are incorrectly dosed or if the combustion temperature becomes too high. Essential oils also have a low flash point, which is the temperature at which they become flammable. Heat can also alter the chemical composition of some oils, changing a sweet scent into an unpleasant odor.
- Opt for fragrances that are specifically designed for diffusion in candles. These fragrances are formulated to withstand heat without degrading or altering their scent. While some of these alternatives may be synthetic, they have been tested for safety, effectiveness, and olfactory rendering.
- If you are set on using essential oils, choose those with higher flash points (above 150°F) and strong aromas, such as lavender, tea tree, peppermint, and ylang-ylang.
- When using essential oils, ensure you have the right equipment, such as a double boiler to control temperature and prevent overheating, and a thermometer to ensure the wax reaches the ideal temperature for essential oil blending and pouring.
- Follow safety guidelines when using essential oils. Store them in a lockable case, out of reach, or in a high-up cabinet with a child lock. Always dilute essential oils with carrier oils, especially before applying them to the skin.
- Consider using essential oil substitutes that are safer for both fragrance and therapeutic actions. For example, Ho Wood is a great alternative to Rosewood, as it provides similar benefits without exploiting the plant.

How to make candles with essential oils
While essential oils seem like a natural and beneficial alternative, they are not very suitable for candle making in terms of safety and olfactory performance. Their flash point (the temperature at which they become flammable) is often low, and they can introduce a risk of ignition if incorrectly dosed or if the combustion temperature becomes too high. Heat can also alter the chemical composition of some oils, transforming a sweet scent into an unpleasant odor.
However, if you wish to make candles with essential oils, there are a few things to keep in mind. Firstly, choose the right wax for your project. Beeswax has a beautiful glow, but it doesn't hold the scent from the oils you add. Soy wax is a good option for scented candles as it burns clean and allows you to create a candle with a stronger scent. Paraffin holds the most scent as the candle burns, but it doesn't burn as cleanly as beeswax or soy.
Next, you'll need to decide on the essential oil. The key thing when using essential oils in candles is that they are pure and don't produce toxins when burnt. The quality of these essential oils should be high, and always check the burning point of each essential oil you use. For example, lavender may burn at a lower temperature than Sweet Orange. You can also get creative and blend different oils to create unique scents.
Once you have your wax and essential oil, it's time to start making your candle. Here's what you'll need:
- Wax
- Essential oils
- Wicks
- Double boiler
- Thermometer
- Wick stickers
- Wick holder
- Scale or measuring cups/spoons
- Container for your candle (such as a glass jar or mason jar)
And here are the steps to make your candle:
- Melt your wax using a double boiler or crock pot.
- Allow the wax to cool to around 150-130°F (65.5-71°C). This is important to prevent the essential oils from evaporating too quickly.
- Add your essential oils to the melted wax. The amount of essential oil you use will depend on the type of oil and its potency, but typically, around 6% concentration is recommended (about 1 ounce per pound of wax).
- Stir the mixture gently for 1-2 minutes to fully incorporate the oils. Be careful not to stir too fast, as this can introduce air bubbles.
- Prepare your container by preheating it and placing a wick sticker on the bottom of your wick. Securely attach the wick to the center of your container.
- Pour the wax and oil mixture into your container.
- Let the candle stand until solid, which usually takes about an hour.
- Cut the wick to the desired length.
There you have it! Your very own essential oil candle. Just remember to always exercise caution when working with essential oils and heat, and enjoy your homemade creation.

Essential oils vs fragrance oils
While essential oils and fragrance oils are both used to scent candles, they have several differences. Firstly, essential oils are made from natural plant materials, whereas fragrance oils are manufactured in a laboratory. This is because fragrance oils are designed to mimic the scent of essential oils or other natural materials.
The natural origin of essential oils means that they are often used for aromatherapy and meditation, as well as in diffusers, massages, and therapeutic baths. They are also prized for their therapeutic properties and purity. However, their scent is not as long-lasting as that of fragrance oils, and they can be more expensive.
Fragrance oils, on the other hand, are synthetically created from artificial chemical components. They are commonly used in commercial products because they hold their fragrance for longer than naturally occurring fragrances. They can also be more strongly scented than essential oils. However, because of their synthetic nature, they can cause adverse reactions in people with sensitive skin or fragrance sensitivities.
Another key difference between the two types of oils is their safety profile. Essential oils have a low flash point, which is the temperature at which they become flammable. This means that using them in candles can increase the risk of accidents, including ignition if they are incorrectly dosed or if the combustion temperature becomes too high. Fragrance oils, being synthetic, do not carry this same risk.

Why do some companies use essential oils in candles?
Consumers are increasingly seeking natural alternatives to traditional home and personal care products, and essential oils have emerged as a popular option. As a result, some companies use essential oils in candles to cater to this growing demand for natural and organic products.
Essential oils are concentrated liquids of compounds extracted from plants, capturing the plant's distinctive aroma or "essence". They are typically produced through distillation with water or steam. The use of essential oils in candles is intended to provide a natural and potentially therapeutic fragrance experience.
However, there are some drawbacks and risks associated with using essential oils in candles. Firstly, essential oils are highly volatile, meaning they evaporate quickly when exposed to heat. This can result in a weak aroma and a shorter fragrance lifespan compared to synthetic fragrance oils. To address this issue, candle makers must use a higher concentration of essential oils, which can increase the cost of production.
Additionally, essential oils have a low flash point, or the temperature at which they become flammable, posing potential safety hazards if not used correctly. They may also not mix well with certain types of wax, leading to uneven fragrance distribution and affecting the texture and burn of the candle.
Despite these challenges, some companies still opt to use essential oils in their candles. This decision may be influenced by the growing consumer preference for natural products, the perceived therapeutic benefits associated with essential oils, and the desire to offer a unique, organic fragrance experience to their customers.
To ensure safety and effectiveness, it is crucial for candle makers to carefully select the appropriate essential oils, follow precise temperature controls during production, and provide clear instructions for safe use to their customers.
