Fragrance Oils: Are They A Fire Risk?

Fragrance oils are flammable and have a flash point, which is the temperature at which they can ignite when exposed to an open flame or spark. The flash point of fragrance oils varies, but most fall between 141° and 200° F (60.5° and 93.3° C). At these temperatures, the oils can combust if there is a large volume of oil in an enclosed space. This is why fragrance oils with a flash point of 141° F (60.5° C) or lower cannot be transported by air. While fragrance oils added to candles during the candle-making process are generally safe, adding extra oil to a burning candle can be dangerous and is not recommended.

Fragrance oils are flammable

It's important to understand that for a fragrance oil to combust at its flash point, several factors must be present. Firstly, there needs to be a large volume of the oil, and it must be contained in an enclosed vessel. Secondly, the vapour emitted from the heated oil must come into contact with a source of ignition, such as a flame or spark. Therefore, simply lighting a candle made with fragrance oil will not cause it to burst into flames. However, adding too much fragrance oil to a candle can be dangerous, as it can cause the oil to separate and form "dew drops" on the surface, creating a potential fire hazard.

When working with fragrance oils, it is crucial to follow safety precautions. This includes adhering to the recommended maximum fragrance oil-to-wax ratio, which is typically around 10%. Additionally, it is important to avoid direct contact between the oil and an open flame or spark. Proper storage and handling of fragrance oils are also essential to minimise the risk of fire. Keeping them in a well-ventilated area, away from electrical outlets and wires, can help reduce the risk of accidental ignition.

The flash point of fragrance oils also has legal implications, particularly for transportation. In the United States, flammable liquids with a flash point at or below 141° F (60.5° C) cannot be transported by air due to their potential to ignite under specific circumstances. This regulation is in place to ensure the safe transport of goods and prevent accidents. Therefore, understanding the flash point of fragrance oils is crucial for both candle makers and those involved in the shipping and handling of these products.

Flash points of fragrance oils

Fragrance oils are flammable and have a flash point—the temperature at which a substance can ignite if it comes into contact with an open flame or spark. The flash point of fragrance oils varies, but most fall between 141° and 200° F (60.5° and 93.3° C).

The flash point of a fragrance oil is important for those making gel candles, as it determines the safety of the candle and the shipping method that can be used. Gel wax manufacturers recommend using fragrance oils with a flash point of 170° F (76.6° C) or higher when making scented gel candles. If a fragrance oil with a flash point below 170° F is used in a gel candle, it can catch fire very quickly.

When making candles, it is important to follow safety precautions and not overload the wax with too much fragrance oil. As long as the recommended amount of fragrance oil is added to the wax and it is not exposed to an open flame or spark, the candle will be safe. However, if too much fragrance oil is added, it can separate and leave "dew drops" on the top of the candle, creating a potential fire hazard.

The flash point of a fragrance oil also determines whether it can be shipped via air mail or must be shipped via ground. In the United States, for example, fragrance oils with a flash point of 141° F (60.5° C) or less cannot be shipped via USPS or UPS 2nd Day Air and must be shipped via ground services.
