Essential oils have become an increasingly popular ingredient in candles due to their natural, therapeutic qualities. They are derived directly from plants and other natural sources and are prized for their mood-boosting qualities. However, there are some concerns about their safety when burned. This is because essential oils have a low flash point, meaning they can be flammable and release harmful chemicals when heated to high temperatures. Therefore, it is important to consider the benefits and drawbacks of using essential oils in candles and whether their therapeutic properties are retained when burned.

Safety concerns: essential oils may release carcinogens when heated
While essential oils are often perceived as natural and safe alternatives to synthetic products, some can release carcinogenic substances when heated to high temperatures. These substances are known as CMRs (carcinogenic, mutagenic, or reprotoxic).
Essential oils have a low flash point, or a low temperature at which they become flammable. This means that when heated, their chemical composition can degrade, reducing the strength of their scent. This can be frustrating, especially if high-quality oils are being used.
Some essential oils contain carcinogenic constituents, including asarone, estragole (methyl chavicol), safrole, and methyleugenol. These carcinogens are found in basil leaves and are concentrated in pesto. However, the anticarcinogens in basil leaves counteract the toxic effects of these carcinogens. It is important to note that these particular anticarcinogens are not found in basil essential oils, but other types of basil oil may contain anticarcinogens.
The carcinogenicity of an essential oil depends on three factors: the percentage of the carcinogenic constituent, the potency of that constituent, and the amount of anti-carcinogenic constituents in the oil. For example, the estragole chemotype of basil oil contains 75-87% estragole and should be used at a maximum topical concentration of 0.1%. On the other hand, the linalool chemotype of basil oil has very little estragole and contains anticarcinogenic linalool and eugenol, so it has no restrictions.
Rose oil, Elemi oil, and Holy Basil oil contain very small amounts of carcinogens, but are not generally considered carcinogenic. However, Calamus oil, Sassafras oil, and Huon Pine oil are considered carcinogenic and are not commonly used in aromatherapy.
Despite the potential risks associated with using essential oils in candles, some sources promote their use as a way to create custom, all-natural scents while avoiding synthetic fragrances and harmful chemicals. It is important to note that synthetic fragrance oils are specifically formulated to withstand heat without degrading, ensuring a consistent scent.

Natural vs synthetic: synthetic fragrances are safer and more effective
The use of essential oils in candles is a topic of debate. While some sources claim that essential oils are a natural and beneficial alternative to synthetic fragrances, others argue that they are not suitable for candle-making due to safety and performance concerns.
Those who support the use of essential oils in candles believe that they offer a safe and aromatic way to create custom, all-natural scents. By making candles with essential oils, individuals can control the ingredients and avoid synthetic fragrances and potentially harmful chemicals. This is particularly appealing to those who are mindful of the toxins that may be present in store-bought candles.
On the other hand, opponents of using essential oils in candles raise several concerns. Firstly, essential oils have low flash points, which means they can be flammable and release substances known as CMRs (carcinogenic, mutagenic, or reprotoxic) when heated to high temperatures. This introduces a risk factor that may not be present with synthetic fragrances, which have been specifically tested for safety. Additionally, essential oils can be inconsistent and may degrade or evaporate at high temperatures, resulting in a weaker scent. The cost of essential oils can also be a factor, as large quantities are needed to achieve a sufficiently strong fragrance.
Synthetic fragrances, on the other hand, offer several advantages. They are developed in laboratories, allowing for consistency and the ability to replicate natural accords without harming the environment. Synthetic fragrances are also longer-lasting, with a shelf life of up to five years compared to the average of one to two years for natural fragrances.
While the preference for natural ingredients and scents is growing, it is important to recognize that synthetic ingredients are still prevalent in most fragrances. This suggests that their negative reputation may not be entirely accurate. Synthetic fragrances allow perfumers to create unique blends and take their creations to the next level. Additionally, synthetic fragrances can help protect the environment and animal welfare by reducing deforestation and the need for animal extracts.
In summary, the debate surrounding the use of essential oils versus synthetic fragrances in candles considers both safety and effectiveness. While essential oils may seem like a natural choice, they come with potential risks and performance limitations. Synthetic fragrances, on the other hand, offer consistency, longevity, and environmental benefits. Ultimately, the decision between natural and synthetic fragrances depends on individual preferences and fragrance needs.

Therapeutic benefits: essential oils can reduce stress and anxiety
Aromatherapy with essential oils is a popular natural remedy for stress relief and reducing anxiety. Essential oils are highly concentrated extracts made from flowers, seeds, stems, leaves, and other plant parts. The olfactory system directly affects the part of the brain that regulates emotion, which is why smells can trigger memories and elicit feelings.
Essential oils are generally considered safe when used properly, but it is important to dilute them in a carrier oil first to prevent adverse reactions. As a general rule, concentration levels of essential oils should be kept below 5%. Some popular essential oils with anti-anxiety properties include lavender, chamomile, rose, and jasmine.
Lavender is one of the most popular essential oils for aromatherapy. It has been shown to reduce workplace stress and create an overall calming effect. Chamomile essential oil is known for its sedative effects and has been used to aid with sleep and anxiety. Rose oil has also been found to help with anxiety, depression, and relaxation. A 2014 study involving over 100 pregnant women found that rose oil lowered their anxiety during delivery. Jasmine oil is derived from the white flowers of the jasmine plant and is known for its calming and uplifting properties. A 2013 study found that participants reported a significant decrease in negative emotions and an increase in overall mood after inhaling jasmine oil.
While essential oils can be added to candles to create custom, all-natural scents, there are some safety concerns. Essential oils have low flash points, which means they can evaporate at high temperatures and release substances known as CMRs (carcinogenic, mutagenic, or reprotoxic). This can limit the strength of their aroma in candles, and increase the risk of accidents, including ignition if they are incorrectly dosed or if the combustion temperature is too high.
Therefore, while essential oils can have therapeutic benefits for stress and anxiety relief when used in aromatherapy, adding them to candles may not be the best way to retain these benefits due to potential safety risks and inconsistent scent diffusion.

Cost: essential oils can be expensive and inconsistent
Adding essential oils to candles can be costly and inconsistent. The price of essential oils varies depending on the plant they are derived from and their yield. Some plants, such as peppermint and spearmint, are easy to grow and produce in abundance, resulting in lower prices. In contrast, plants like sandalwood, which must reach maturity before harvesting, yield less oil and are significantly more expensive. For example, it takes 250 pounds of lavender flowers to produce one pound of essential oil, but for rose oil, this figure rises to 10,000 pounds of petals. Additionally, certain botanicals, like Melissa, are highly sensitive and must be harvested at a specific time of day, making the process more time-intensive and challenging.
The rarity and difficulty of growing certain plants also contribute to higher prices. For instance, frankincense and myrrh are challenging to cultivate outside their native environments, making them rarer and more costly. The type of plant, such as a herb or tree, and the plant part used, including flowers, leaves, or roots, influence the labour intensity of harvesting and processing. Furthermore, the purity, shipping costs, and brand reputation of the essential oil can impact its price.
The inconsistency in essential oil prices can be confusing for consumers. For example, sweet orange oil may cost around $4 per bottle, while lavender oil is priced at less than $13, and rose absolute oil is nearly $60 for a smaller bottle. The higher price does not always indicate higher quality, but it often reflects the complexity of the source plant and the challenges in growing and harvesting it.
While essential oils can provide natural scents for candles, their cost can quickly add up, especially when using large quantities to achieve a sufficiently strong fragrance. Synthetic fragrance oils, although not natural, may offer a more affordable and consistent alternative for candle-making. These oils are manufactured in laboratories to recreate scents that cannot be derived naturally or do not exist in nature, such as fruity notes and scents like amber, vanilla, and chocolate. However, it is important to purchase these oils from reputable suppliers to ensure safety and quality.
