What You'll Learn
Some essential oils are toxic when burned
Essential oils are highly concentrated volatile organic compounds extracted from plant materials such as leaves, flowers, and wood. They are popular for their potent aromatic fragrances and therapeutic properties, which make them useful in skincare, massage, and aromatherapy. However, this does not mean that they are completely safe for all applications. Some essential oils can be poisonous when absorbed through the skin or inhaled, and they should be used with caution and kept away from children, pets, and pregnant people.
When used in candles, essential oils introduce a risk factor that is not always suspected. Essential oils have a low flash point, or a low temperature at which they become flammable, and they can increase the risk of accidents, including ignition if they are incorrectly dosed or if the combustion temperature becomes too high. The heat from a candle flame can destroy the properties of essential oils, diminishing their intensity and efficacy, and altering their chemical composition. This can result in a harsh, unpleasant odor and the production of toxic fumes, which may negatively impact indoor air quality and cause adverse reactions in people with allergies, asthma, or respiratory issues.
Oxidation of essential oils can also make them toxic, and they must be expertly blended and wicked to ensure they burn at an ideal temperature to prevent oxidation. Essential oils typically lose their scent quickly when exposed to heat, requiring frequent refills, and they do not always mix well with waxes, leading to uneven fragrance distribution. Safer alternatives exist to scent candles, such as fragrances designed for diffusion in candles, which have been tested for safety and effectiveness and can withstand heat without degrading or altering their scent.
It is important to note that the fragrance industry is protected by trade secrets, and companies are permitted to withhold fragrance ingredients. Therefore, consumers cannot always rely on labels to understand potential health hazards that may be present in scented candles. When choosing to use essential oils, it is recommended to consult a reliable website, reference book, or qualified aromatherapist.

Heat can alter the chemical composition of essential oils
Essential oils are highly concentrated liquids derived from plants and contain aromatic compounds with therapeutic properties. They have been used for hundreds of years for aromatherapy, skincare, and stress relief.
The impact of heat on essential oils depends on factors such as temperature, duration of exposure, and the specific chemical composition of the oil. Not all oils react to heat in the same way; some may withstand higher temperatures better than others due to their chemical makeup. Heat exposure can be beneficial for some oils, as it can increase the release of their aromas, making them more potent and easier to absorb into the skin. However, heat can also damage essential oils, causing them to lose their therapeutic properties. For example, citrus oils and lavender oil are particularly susceptible to heat exposure due to their high content of limonene and linalool, respectively, which are compounds easily broken down by heat.
To preserve the quality of essential oils, they should be stored in a cool, dark place and properly sealed. When heating essential oils, it is important to use gentle heating methods such as diffusers, warm water baths, crockpots, or candle warmers. These techniques allow the oils to be warmed gradually, preserving their therapeutic benefits. Direct heat sources like open flames or microwaves should be avoided, as they can cause rapid and uneven heating, leading to degradation of the oils. Maintaining proper ventilation is also crucial when heating essential oils to prevent respiratory issues and ensure a soothing atmosphere.

Essential oils have a low flash point
Essential oils are highly concentrated plant substances. They are used in candles to create custom, all-natural scents while avoiding synthetic fragrances and harmful chemicals. However, essential oils have a low flash point, which is important to be aware of for safe handling, storage, and disposal.
The flash point of a substance is the lowest temperature at which it gives off enough vapour to ignite in the air when exposed to an ignition source. Essential oils have varying flash points, with some having low flash points below 60°C, such as Sweet Orange, Grapefruit, Peppermint, Roman Chamomile, and Black Pepper. These oils are considered flammable and require special handling and shipping procedures.
When making candles with essential oils, it is important to choose containers made from heat-resistant materials such as glass, enamel, or tin. It is also crucial to ensure that the wax is cool enough before adding essential oils to prevent the loss of their aromatic and therapeutic properties. The recommended amount of essential oil added to wax is generally low, typically around 3% of the total weight of the wax, to avoid affecting the candle's burn.
Additionally, it is important to be cautious when using essential oils in their concentrated form. They should be stored in a cool, dark place, away from children and pets. Inhalation of concentrated essential oils can be overwhelming, and direct contact with the skin or eyes can cause irritation. If ingested, it is recommended to drink water and/or milk and seek medical advice if discomfort occurs.
In summary, essential oils have varying flash points, with some having low flash points, making them flammable. When used correctly and safely, essential oils can be enjoyed in candles, providing aromatic and therapeutic benefits. However, it is important to be aware of the specific flash points and take the necessary precautions during handling and storage to ensure a safe and enjoyable experience.

Essential oils can be dangerous to certain demographics and pets
While essential oils are natural and derived from plants, they are not completely safe. They can be toxic when absorbed through the skin or if aspirated. Essential oils are highly concentrated, and when inhaled in their undiluted form, some oils can trigger headaches.
Some essential oils are dangerous to pets when inhaled in their pure form. These include anise, clove, garlic, horseradish, juniper, thyme, wintergreen, and yarrow. Essential oils should be stored away from children and used with caution around children, the elderly, pregnant people, and those with medical conditions such as epilepsy.
The heat from a candle flame can alter the chemical composition of essential oils, transforming their scent and potentially making them toxic or allergenic. This is particularly concerning for people with allergies, asthma, or respiratory issues, who might experience adverse reactions when exposed to such fumes.
Oxidation of essential oils can also make them toxic. When burned, essential oils may release toxic fumes due to the breakdown of their chemical components. This can negatively impact indoor air quality.
It is important to note that candles made with essential oils are usually scented with a maximum of 10-11% of essential oils, so they are diluted and considered safe. However, it is always good to consult a qualified aromatherapist when bringing essential oils into your home.

Synthetic fragrances are safer and more effective
While essential oils are derived from natural sources, such as plants, flowers, or animals, synthetic fragrances are produced from man-made materials, such as petrochemicals (petroleum-based chemicals). Synthetic fragrances are often labelled as "fragrance oils" and are created using synthetic chemicals. However, non-toxic synthetic fragrances are formulated to be safe for use in personal care and household products.
Synthetic fragrances offer several advantages over essential oils. Firstly, they are often created to be free of potentially harmful ingredients such as phthalates and synthetic musks, which have been linked to health concerns such as hormone disruption and cancer. By avoiding these ingredients, synthetic fragrances can reduce the risk of endocrine disruption and potential carcinogenic effects. This is particularly relevant as essential oils can contain allergens and irritants that can lead to skin irritation, redness, and allergic reactions in sensitive individuals.
Additionally, synthetic fragrances provide a more consistent and reliable scent experience compared to natural fragrances, which can vary in scent and strength depending on the source of the plant or flower and the conditions in which it is grown. Synthetic fragrances are also more sustainable, as the production of natural fragrances often involves the use of large amounts of water, pesticides, and fertilizers, which can negatively impact the environment.
Furthermore, synthetic fragrances can be produced using fewer natural resources and with less environmental impact. They do not require the extraction processes associated with essential oils, such as steam distillation or cold pressing, which can be resource-intensive and polluting. Instead, synthetic fragrances can be synthesized in a laboratory, making them a more efficient and environmentally friendly option.
While synthetic fragrances offer these benefits, it is important to note that not all synthetic fragrances are safe. Some synthetic fragrances may still contain harmful chemicals, and vague labelling can make it difficult for consumers to know the specific ingredients used. Therefore, it is crucial for consumers to research and choose reputable brands that prioritize the safety and well-being of their customers.
