Essential oils are highly fragrant, 100% natural, and have become popular in candle-making in recent years. They are derived from plants and are often associated with well-being and therapeutic benefits. However, they are not without risks. When heated to high temperatures, some essential oils can release toxic compounds and may affect the texture, burn, and scent of the candle. They also have low flash points, which can increase the risk of ignition. As a result, fragrance oils, which are synthetic, are often used in candles as they are designed to be long-lasting and potent. However, some people prefer essential oils for their natural properties and eco-friendliness. So, is skincare-grade essential oil good for candles? The answer is complex, as there are benefits and drawbacks to using essential oils in candles, and it is important to understand how they interact with candle wax to ensure safety and effectiveness.
Characteristics and values of skincare-grade essential oils in candles
| Characteristics | Values |
|---|---|
| Safety | Some sources claim that essential oils can be dangerous in candles due to their potential to release carcinogenic, mutagenic, or reprotoxic (CMR) substances when heated to high temperatures. However, other sources claim that essential oils are safe and free from harmful toxins. |
| Natural | Essential oils are 100% natural, extracted directly from plants, and free from synthetic additives or chemicals. |
| Fragrance | Essential oils offer a natural fragrance that is identical to its source, such as citrus fruits or flowers. However, they may lose their scent quickly when exposed to heat, resulting in a weak hot throw. |
| Eco-friendliness | Essential oils are eco-friendly, but the large amount of plant material required to produce a small amount of oil may not be sustainable. |
| Cost | Essential oils are expensive due to the high cost of extraction and the large quantity of oil needed to achieve a sufficient fragrance in candles. |
| Wellness | Essential oils offer therapeutic and mood-boosting qualities, such as lavender's calming, anti-anxiety effects. |

What You'll Learn
Essential oils are natural, but not necessarily safe for candles
Essential oils are natural extracts from plants, often associated with wellbeing. They are highly fragrant and prized for their therapeutic and mood-boosting qualities. For example, lavender oil can act as a mild sedative, while citrus oils can make you feel more energetic and positive.
However, natural does not always mean safe. Some essential oils can release toxic compounds known as CMRs (carcinogenic, mutagenic, or reprotoxic) when heated to high temperatures, as is the case with candles. For instance, oils like cinnamon, clove, and lavender can release these toxic compounds. Essential oils have low flash points, or low temperatures at which they become flammable, increasing the risk of accidents, including ignition if incorrectly dosed or if the combustion temperature is too high.
Essential oils can also be expensive, as it takes a large quantity of plant material to produce a small amount of oil. For example, it takes 250 pounds of lavender flowers to make one pound of lavender oil and 10,000 pounds of rose petals to make one pound of rose oil. This high cost can limit their effectiveness in candles, as a large quantity of oil is needed to achieve a sufficiently strong fragrance.
Additionally, essential oils may not mix well with certain types of wax, leading to uneven fragrance distribution or candles with little to no scent when lit. They can also affect the texture and burn of the candle, compromising its effectiveness and aesthetic appeal. While essential oils are natural and can provide health benefits, they are not necessarily the safest or most effective option for candles due to these potential drawbacks.

They may release harmful substances when heated
While skincare-grade essential oils are often associated with well-being, they may not be suitable for candles due to the potential release of harmful substances when heated.
Essential oils are natural, highly concentrated extracts from plants, containing various chemical compounds. When heated to high temperatures, such as in a candle flame, their chemical composition can change. This alteration can result in the release of potentially toxic compounds known as CMRs (carcinogenic, mutagenic, or reprotoxic substances). For example, commonly used oils like cinnamon, clove, or lavender can become toxic when burned.
The flashpoint, or the temperature at which essential oils become flammable, is often low for these oils. This low flashpoint increases the risk of accidents, including ignition if the dosage or combustion temperature is not carefully controlled. Additionally, essential oils tend to lose their scent quickly when exposed to heat, requiring frequent refills without ensuring a consistent fragrance diffusion.
The interaction between essential oils and candle wax can also be challenging. Essential oils may not mix well with common waxes like soy or beeswax, leading to uneven fragrance distribution. Furthermore, the high concentration of essential oils in candles can result in combustion.
While some sources advocate for the use of essential oils in candles, emphasizing their natural properties and therapeutic benefits, it is crucial to approach candle-making with caution. The potential release of harmful substances when heated highlights the need for careful consideration and further exploration of safe alternatives.

They can be expensive and inconsistent
While essential oils are natural and highly fragrant, they can be expensive and inconsistent when used in candles. The price of essential oils can be high because it takes a lot of plant material to produce a small amount of oil. For example, it takes around 50 pounds of eucalyptus to create one pound of eucalyptus oil, 250 pounds of lavender for one pound of lavender oil, and a whopping 10,000 pounds of roses for one pound of rose oil. This means that even a tiny 5ml jar of rose essential oil can cost around $200-250. When used in candles, essential oils may not provide a strong enough scent, as they have low flash points and can evaporate at high temperatures. This can result in a disappointing hot throw, where the scent is not diffused well and quickly fades.
The inconsistency of essential oils in candles can be frustrating, especially given their high cost. Their chemical composition can degrade when heated, reducing the strength of the scent or even transforming a sweet fragrance into an unpleasant odour. Additionally, essential oils don't always mix well with waxes like soy or beeswax, leading to uneven fragrance distribution. This can further impact the effectiveness and aesthetic appeal of the candle.
The expense of essential oils can be a significant factor when considering their use in candles. While they are natural and highly sought-after, the large quantity of oil needed to achieve a noticeable fragrance can drive up the cost. This may put them out of reach for many consumers, especially when compared to synthetic fragrance oils, which tend to be cheaper.
However, it's important to note that fragrance oils may not always be a perfect substitute for essential oils. While they are designed to be potent and long-lasting, they are not natural and may not offer the same therapeutic benefits as essential oils. Fragrance oils are created using synthetic chemicals, which can be off-putting to those seeking more natural alternatives. Additionally, some individuals may have allergies or skin sensitivities to certain fragrance oils, making essential oils a preferred choice in such cases.
In conclusion, while essential oils can be expensive and inconsistent when used in candles, they offer a natural and therapeutic option that may be preferred by those seeking eco-friendly and wellness-focused alternatives. However, the high cost and potential scent issues are important considerations when deciding whether to use essential oils for candle-making.

Some people use them for their therapeutic benefits
While essential oils are often associated with well-being, they are not without risks when used in candles. Some people use them for their therapeutic benefits, such as lavender oil, which has a calming, anti-anxiety effect due to the presence of linalool, a compound that calms the central nervous system. Citrus oils can also make you feel more energetic and positive. However, it's important to note that essential oils can be irritating to some individuals depending on allergies or skin sensitivity, and they should be used with caution around young children and pets.
Essential oils are natural, highly concentrated extracts from plants, and their scent is often identical to their source, bringing the best elements of nature into your home. They are also prized for being eco-friendly, containing no additional additives or chemicals, and not releasing harmful toxins when burned.
However, essential oils are not without their drawbacks when used in candles. They have a low flashpoint, meaning they can combust if there is a high concentration in a candle. They can also be challenging to work with due to their low flashpoints, which cause them to evaporate at high temperatures, limiting the strength of their aroma. The scent can be inconsistent, and the oil may burn up without leaving much fragrance.
Additionally, essential oils can be expensive, as it takes a large quantity of plant material to produce a small amount of oil. For example, it takes 250 pounds of lavender flowers to make one pound of lavender oil. They may also not mix well with certain types of wax, resulting in uneven fragrance distribution.
While essential oils have therapeutic benefits, it is important to be aware of their potential drawbacks when using them in candles.

Fragrance oils are often a safer, cheaper alternative
While essential oils are natural and directly extracted from plants, fragrance oils are man-made in laboratories. The former are often used in perfumes, soaps, cosmetics, household cleaners, incense, and medicines, but they are not created for the primary purpose of scenting candles. Essential oils are also highly volatile, with a lower boiling point, and can quickly lose their scent when exposed to heat.
Fragrance oils, on the other hand, are specifically designed for candles and offer a stronger, longer-lasting scent. They are also generally cheaper than essential oils, especially when purchased in bulk. For example, fragrance oils can be bought for under $2 per ounce, while essential oils rarely go for less than $5 per ounce.
The use of essential oils in candles can also be potentially dangerous. Some essential oils can release substances known as CMRs (carcinogenic, mutagenic, or reprotoxic) when heated to high temperatures. They also have a low flashpoint, or the temperature at which they become flammable, which can increase the risk of accidents.
For these reasons, fragrance oils are often considered a safer, more cost-effective alternative to essential oils in candles. While some may prefer essential oils due to their natural ingredients and potential health benefits, fragrance oils have been tested and scientifically approved for use in candles and other products. They also provide a more consistent fragrance experience, as essential oils can be unpredictable when burned.
