Choosing Fragrance Oils For Candles: What You Need To Know

Creating scented candles is an enjoyable hobby and a great way to fill your space with delightful fragrances. While it may seem like a good idea to use perfume oils in candles, it is not recommended as perfumes are not designed to be mixed with candle wax and will likely result in an inconsistent, chunky mixture. Instead, fragrance oils and essential oils are better alternatives for candle-making.

Fragrance oils, which are crafted using chemical compounds, offer a stronger and longer-lasting scent. They are specifically designed for candle-making and provide a wider variety of scent options. Essential oils, on the other hand, are derived from natural substances like plants, flowers, and leaves, and are often used for their therapeutic benefits. However, not all essential oils are suitable for candle-making due to their lower flash points and higher volatility, which can lead to evaporation when exposed to high temperatures.

Both fragrance oils and essential oils can be used to create beautifully scented candles, but it is important to consider their unique properties and choose oils with higher flash points to ensure a safe and effective outcome.

Fragrance oils are synthetic scents, while essential oils are natural extracts

Fragrance oils and essential oils are both used to add scent to candles, but they have distinct characteristics and origins. Fragrance oils are synthetic scents, produced in a laboratory to imitate natural scents. On the other hand, essential oils are natural extracts derived from plants and other natural materials.

Fragrance oils, also known as perfume oils, are artificially created fragrances or scents. They are designed to mimic the scent of natural products but contain artificial substances. These oils are commonly used in manufacturing fragrances, cosmetics, and flavourings. They are also widely used by soap and candle makers to enhance the scent of their products. While fragrance oils can replicate the smell of essential oils, they lack the therapeutic benefits associated with them. For instance, lavender essential oil is known for its calming properties, which may aid in insomnia, cough, hyperactivity, and muscle aches.

Essential oils, on the other hand, are highly concentrated liquid plant extracts. They are called "essential" because they capture the essence of a plant. These oils are obtained from different parts of plants, including the leaf, stem, blossom, fruit, bark, wood, or resin. The most common methods of extraction are cold pressing and steam distillation. Aromatherapy essential oils are valued for their therapeutic properties and ability to enhance mood and relieve symptoms such as pain, fatigue, and inflammation.

When it comes to using these oils in candles, there are some important considerations. Fragrance oils are often preferred due to their stronger and longer-lasting scent. They are specifically designed for candle-making and offer a wider variety of scents at a more affordable cost. However, essential oils offer natural scents and can provide therapeutic benefits through aromatherapy. It is crucial to note that not all essential oils are suitable for candle-making due to their lower flash points and volatility. Essential oils with higher flash points, such as camphorous, floral, herbal, and mint oils, are generally safer options for candle-making.

In summary, fragrance oils are synthetic scents created in laboratories, while essential oils are natural extracts derived from plants. While fragrance oils offer a wider range of scents and stronger fragrance, essential oils provide natural scents and potential therapeutic benefits. The choice between the two depends on the user's preference for scent type, strength, and desired benefits.

Essential oils are more costly to produce

Essential oils are more expensive to produce than fragrance oils. Firstly, essential oils are entirely natural products, extracted from plant sources through distillation or expression. This process is generally more expensive than creating a synthetic fragrance oil. The price of essential oils can also be influenced by the cost of the plant material used, as a large amount is required to produce a small quantity of oil. For example, at the time of writing, Rose Absolute costs £3,500/kg, Jasmine Absolute costs £5,500/kg, and Neroli Oil costs £2,500/kg.

Additionally, essential oils are often highly concentrated, with a small amount of oil having a big impact on the overall price of the product. The quality of essential oils can also be a factor, as pure, high-quality oils are more expensive than those that are diluted with base oils.

The process of creating essential oils is more complex and time-consuming, which contributes to the higher cost. Steam distillation, for instance, involves heating plant components to release a gas, which must then be condensed back into a liquid. This gentle process ensures that the sensitive compounds in the plants do not break down.

The cost of producing essential oils is further increased by the fact that not all plants produce essential oils. For example, there are no essential oils of strawberry or vanilla, which limits the options available and may increase the price.

Overall, the natural extraction process, high concentration, and limited plant sources of essential oils contribute to their higher production costs compared to fragrance oils.

Essential oils are more volatile and have a lower flash point

When it comes to candle-making, essential oils are a popular choice for infusing your space with delightful fragrances. However, it's important to understand that essential oils have unique characteristics that set them apart from fragrance oils. One key distinction is that essential oils are more volatile and have lower flash points.

Volatility in essential oils refers to their tendency to evaporate quickly when exposed to high temperatures, such as the heat of hot candle wax. This is due to their lower flash points, which is the minimum temperature at which an oil turns into vapour and can be ignited. Because of this, essential oils with low flash points may not be suitable for candle-making as they can evaporate before the candle has completely burned down, resulting in a less potent aroma over time.

The flash point of an essential oil can vary greatly depending on the specific oil used. For example, some essential oils with low flash points include rosemary oil (117°F/47°C), lavender oil (204°F/96°C), and grapefruit oil. On the other hand, essential oils with higher flash points, such as sandalwood, patchouli, and ylang-ylang, are often better choices for candle-making as their scent is more likely to linger when burned.

It's crucial to consider the flash point when choosing an essential oil for candle-making. If the wax is too hot when the essential oil is added, it can burn the oil, resulting in a loss of scent. Therefore, it's important to add essential oils to wax at a temperature below their flash point to ensure the oil doesn't ignite and the fragrance remains intact.

Additionally, the type of wax used can also impact the performance of essential oils in candles. Soy wax, for instance, has a lower melting point, making it a good choice for essential oil candles as it burns slower and holds fragrance well. However, beeswax has a natural scent that may not blend well with certain essential oils, and paraffin wax, while having an excellent scent throw, is less eco-friendly.

In conclusion, while essential oils can be used in candle-making, their volatility and lower flash points are important considerations. By choosing essential oils with higher flash points and considering their compatibility with wax, you can create beautifully scented candles that enhance your space and promote well-being.

Essential oils may not blend well with wax

While essential oils are popular, not all of them blend well with wax. This is because they have a lower flash point than fragrance oils and are more volatile, meaning they can evaporate when exposed to the high temperatures of hot candle wax.

Some essential oils have lower boiling points than wax and will evaporate more quickly when exposed to heat, leading to a shorter-lasting scent. For example, lavender oil boils at 204°F, which is lower than the boiling point of water at 212°F. Other essential oils with low boiling points include rosemary oil, sweet orange oil, grapefruit oil, and peppermint oil.

Citrus-based essential oils, such as lemon and lime, are also not recommended for use in candles as their fragrances may not last as long as desired due to their low flash points.

Additionally, some essential oils may not produce pleasant aromas when burned, affecting the overall candle experience.

Furthermore, certain essential oils can be expensive, so if budget is a concern, artificial fragrance oils can be a more cost-effective alternative.

When choosing an essential oil for candle making, it is important to consider not only the scent but also volatility, scent retention, cost, compatibility with wax, and carriers. To improve compatibility with wax, carrier oils can be used to dilute essential oils. However, some carriers used to dilute essential oils, such as jojoba oil, may not be soluble in wax or could pose safety concerns.

Therefore, it is crucial to select essential oils with higher flash points and good scent retention when heated. Soy wax, known for its clean burn, pairs well with almost any essential oil, making it a versatile choice for candle making.

Fragrance oils are designed to withstand high temperatures

When it comes to candle-making, it is important to note the difference between fragrance oils and essential oils. Fragrance oils are synthetic scents specifically designed for candle-making, while essential oils are natural extracts from plants. Although essential oils can be used in candle-making, they have a lower flash point and are more volatile, meaning they can evaporate when exposed to high temperatures.

The flash point is the temperature at which an oil can ignite. It is important to ensure that the temperature of the wax when adding the oil is below its flash point to prevent any fire risk. Fragrance oils, with their higher flash points, are therefore a safer choice for candle-making.

Additionally, some essential oils may not blend well with candle wax, which can cause issues during the candle-making process. Carrier oils can help with this, but some carriers used to dilute essential oils, such as jojoba oil, may not be soluble in wax or could pose safety concerns.

Good-quality fragrance oils, on the other hand, blend well with wax and give off a strong, long-lasting scent. They are designed to withstand high temperatures and bond effectively with wax, ensuring that your candles smell great and burn safely.
