Are Scented Candles Safe? Fragrance Oil Health Risks

The use of fragrance oils in candles is a topic of interest, especially with the growing popularity of scented candles. While fragrance oils are commonly used to create long-lasting and intense scents, there are concerns about their potential impact on health and the environment. Fragrance oils are synthetic scents manufactured in laboratories, while essential oils are natural fragrances extracted from plants. The key difference lies in their production methods, resulting in varying levels of scent intensity, sustainability, and therapeutic benefits. Understanding the pros and cons of each type of oil is essential for informed decisions when choosing or creating scented candles.

Fragrance oils are manufactured in a lab and contain chemicals and petroleum by-products

Fragrance oils are manufactured in a laboratory and contain chemicals and petroleum by-products. They are created to be used in candles, perfumes, soaps, and other scented products. Fragrance oils are designed to create a long-lasting "scent throw".

Fragrance oils are made from synthetic compounds or by-products of petroleum. They contain a chemical called Diethyl Phthalate (DEP), which acts as a solvent to elevate the fragrance and make it last longer.

According to a report by the National Academy of Sciences (NAS), approximately 95% of the chemicals used in synthetic fragrance oils are derived from petroleum. These chemicals include aldehydes, benzene derivatives, and toluene, which are also found in toilet bowl cleaners, paint thinners, wart removers, and insect repellents.

The Agency for Toxic Substances & Disease Registry (ATSDR) lists these ingredients as toxic substances, with warnings about the potential health risks associated with exposure to toluene.

The manufacturing process of fragrance oils is less resource-intensive than that of essential oils, as it does not require the physical extraction of oils from plants. However, it is important to consider the environmental impact of the synthetic substances used in fragrance oils, such as petroleum, which is sourced through unsustainable methods like drilling for oil.

While fragrance oils offer a stronger and more intense aroma, a longer-lasting scent, and more exotic smells, it is important to note that they do not provide the same aromatherapeutic benefits as essential oils. Fragrance oils can replicate the scent of aromatic plants, but they may not have the same "healing" properties as essential oils derived from natural plants.

Fragrance oils are not considered real fragrances and lack the medicinal effects of essential oils

Fragrance oils are synthetic scents that are made in a laboratory. They are not considered "real" fragrances, and they lack the medicinal effects of essential oils. While fragrance oils can be used to replicate the scent of aromatic plants, they do not possess the same therapeutic properties as essential oils.

Essential oils, on the other hand, are considered "natural" fragrances. They are extracted from various aromatic plants or tree roots and undergo an intensive manufacturing process to obtain the oil. This process ensures that the oils retain the medicinal and therapeutic properties of the plants they are derived from.

One of the key differences between fragrance oils and essential oils is their impact on health and aromatherapy. Fragrance oils, being synthetic, do not provide the same health benefits as essential oils. Essential oils, due to their natural origin, have been shown to have multiple health benefits, including antimicrobial, anti-inflammatory, analgesic, and antioxidant properties.

For example, studies have shown that lavender essential oil can relieve stress and tension in the body. Other essential oils, such as peppermint, bergamot, eucalyptus, and cinnamon, have been used to reduce stress, relieve anxiety, and promote wound healing. The medicinal effects of essential oils have been recognized and utilized in various fields, including medicine, aromatherapy, and cooking.

In contrast, fragrance oils may contain chemicals and petroleum by-products that can be harmful to health. According to a report by the National Academy of Sciences (NAS), approximately 95% of the chemicals used in synthetic fragrance oils are derived from petroleum. These chemicals include aldehydes, benzene derivatives, and toluene, which are also found in household cleaning products and insect repellents. Exposure to these chemicals can have adverse effects on human health, including headaches, dizziness, nausea, and even more severe consequences in cases of serious exposure.

In summary, fragrance oils are not considered real fragrances and lack the medicinal effects of essential oils. While they can be used to create strong and long-lasting scents, they do not provide the therapeutic benefits associated with essential oils. Essential oils, being natural extracts, offer a range of health benefits that have been recognized and utilized in various industries.

Essential oils are natural and extracted directly from plants and other sources

Aromatherapy is the practice of inhaling or directly applying essential oils to the skin to achieve physical, psychological, and spiritual well-being. While essential oils are thought to be natural and pure products, they are highly caustic and should be used with care.

Essential oils are compounds extracted directly from plants. They capture the plant's scent and flavour, or "essence". They are obtained through distillation (via steam and/or water) or mechanical methods such as cold pressing.

The chemical composition of each individual oil is not widely known by the general public. In the manufacturing process, essential oils often undergo "post-treatment", which allows for the removal of specific chemicals, the concentration of the oil, or a change in colour. The final composition of each oil can vary based on factors such as the country of production, harvest year, and production process.

The extraction process for essential oils is usually resource-intensive and requires the destruction of plants. If the plant or tree used for the oil is endangered or slow-growing, this extraction process puts the species at further risk of extinction.

Despite the fact that essential oils are more challenging to work with, some candle-makers prefer this option because the ingredients are all-natural and may yield certain health benefits.

Essential oils are more volatile and flammable, and less stable than fragrance oils

When it comes to candles, the fragrance is a key consideration. The scent is what fills your home with a unique feeling and makes the candle-buying experience so personal. These fragrances typically come from either essential oils or fragrance oils. While both have their pros and cons, it's important to understand that essential oils are more volatile and flammable and less stable than fragrance oils.

Volatility and Flammability

Essential oils are highly volatile substances due to their high concentration of organic compounds, such as terpenes, alcohols, and phenols. These compounds have low boiling points, which means that essential oils evaporate quickly when exposed to heat. Additionally, they have a low flash point, which is the temperature at which they can ignite and produce flammable vapors. This makes essential oils highly flammable, especially in their purest forms. The presence of certain compounds, such as eugenol, further contributes to their volatile nature.

On the other hand, fragrance oils are manufactured in a laboratory and are designed to create a long-lasting scent. They often contain Diethyl Phthalate (DEP), a chemical that acts as a solvent to elevate and prolong the fragrance. While fragrance oils can also be flammable, their specific composition determines their flammability, and they are generally less volatile than essential oils.

Stability

Essential oils are less stable than fragrance oils due to their natural origins. They are extracted directly from plants and tree roots, which means their quality can vary depending on factors such as how the plants were grown, stored, and transported. The scent of essential oils in candles also tends to be less powerful and reliable, as natural scents are usually not as strong.

Fragrance oils, on the other hand, are synthetic and completely manufactured, resulting in a stronger and more consistent aroma. They are designed to be user-friendly and long-lasting, making them a popular choice for candle makers. The curation process for fragrance oils is also less resource-intensive, as it doesn't require the physical extraction of oils from plants.

Safety Considerations

When using essential oils, it is crucial to take safety precautions due to their volatile and flammable nature. This includes avoiding open flames, using them in well-ventilated areas to prevent the buildup of flammable vapors, and diluting them appropriately with carrier oils to reduce their flammability. Proper storage is also essential, such as keeping them in a cool, dark place, preferably in amber-colored bottles, to prevent degradation and increase their shelf life.

While fragrance oils are generally considered safer in terms of flammability, they still require proper storage and usage guidelines to be followed. Keeping them away from heat sources and open flames is essential to minimize any fire risk associated with their use.

Essential oils are more expensive to create and lack variation in scent

While fragrance oils and essential oils are both used to scent candles, there are some key differences between the two. Fragrance oils are manufactured in a laboratory, while essential oils are extracted directly from natural sources, such as plants. This extraction process is what makes essential oils more expensive to create.

The cost of an essential oil depends on the growth and lifecycle of the plant, the essential oil yield of the plant, and the labour involved in harvesting and processing it. For example, plants that are easy to grow in abundance, like peppermint, are less costly than plants that need to reach a certain age of maturity before they can be harvested, like sandalwood. Additionally, some plants produce a higher yield of essential oil than others. It takes about 250 pounds of lavender flowers to produce one pound of essential oil, but it takes 10,000 pounds of rose petals to produce the same amount.

Essential oils also tend to lack variation in scent compared to fragrance oils. This is because fragrance oils are specifically designed to create a long-lasting scent throw, whereas essential oils are more volatile and evaporate more quickly when exposed to heat. This makes it difficult to get the fragrance just right in an essential oil-based candle, and the scent often doesn't last as long as it does with fragrance oils.

However, some people prefer essential oils because the ingredients are all-natural and may offer health benefits. Essential oils have been used in a wide range of fields, including medicine, aromatherapy, and cooking. While fragrance oils may smell similar and trigger emotions, they don't provide the same benefits as essential oils.
