Flashpoints are crucial when it comes to making candles with fragrance oils. The flashpoint of a fragrance oil is the temperature at which the oil can combust if exposed to an open flame or spark. This is important information for those making gel candles, as fragrances with flashpoints below 76°C should be avoided as they may combust when they come into contact with gel waxes. It is also important for air shipments, as fragrances with low flashpoints cannot be shipped via air. For example, in the US, fragrance oils with a flashpoint at or below 141°F cannot be transported by air.

What You'll Learn
Flashpoint is the temperature at which a fragrance oil can ignite
The flashpoint of a fragrance oil is important to know when making candles. If you heat a pot of pure fragrance oil to its flashpoint and then expose it to an open flame, the vapors could potentially ignite and put you at risk of being burned. However, this is not a situation that you are likely to encounter when making candles safely. When making candles, fragrance oil is typically added to hot wax, creating a mixture with different properties than the individual components. As long as the fragrance oil is added to the wax and poured soon, it will not lose its strength. Repeatedly cooling and reheating batches of fragranced wax should be avoided, as this can affect the strength of the scent.
The flashpoint of a fragrance oil is also important for air shipments. Fragrances with low flashpoints cannot be shipped via air due to their potential to ignite under certain circumstances. For example, fragrance oils with a flashpoint at or below 141°F (60.5°C) cannot be transported by air in the United States. Additionally, Penreco recommends using fragrance oils with flashpoints over 170°F (76.6°C) in gel waxes for gel candles.
It is important to note that simply reaching the flashpoint temperature of a fragrance oil will not cause mass evaporation of its notes. However, heat does accelerate the evaporation process, and if the fragrance oil reaches its boiling point, mass evaporation will occur, resulting in a significant loss of scent. Therefore, it is recommended to store fragrance oils in darker areas and at room temperature to prevent the breakdown of fragrance bonds by light and heat.

The flashpoint of fragrance oils is a legal term
The flashpoint is an important consideration for candle-makers who may be ordering fragrance oils online, as flammable liquids with a flashpoint at or below 141° F (60.5° C) cannot be transported by air due to their potential to ignite. Candle-makers should also be aware that heating and cooling a pot of fragranced wax can affect how strong the final product smells. However, adding fragrance oil to wax that is hotter than the oil's flashpoint will not impact the scent.
It is worth noting that the flashpoint is not the temperature at which fragrance oil will "burn off" or begin to dissipate. In fact, the evaporation rate at or near the flashpoint is negligible, and the risk of "cooking out" the fragrance is generally overstated. Nevertheless, it is important to store fragrance oils in a dark and cool place to prevent light and heat from damaging the bonds in the fragrance and causing evaporation of the notes.
For those making gel candles, it is recommended to use fragrances with flashpoints over 170° F (76.6° C) in their gel waxes. This is because fragrances with lower flashpoints may combust when they come into contact with gel waxes.

Flashpoints are crucial for air shipments
A flashpoint is the temperature at which a fragrance oil can combust if exposed to an open flame or spark. In other words, it is the minimum temperature at which a liquid gives off vapour in sufficient concentration to ignite. Vapours play a role in fragrance oils, and the warmer a fluid is, the more vapour it releases into the atmosphere.
The flashpoint is also important for candle-makers, as adding fragrance oil to wax above the oil's flashpoint will degrade the fragrance, damaging the lighter notes and resulting in a weaker scent. However, adding fragrance oil to wax at a temperature below the oil's flashpoint will not cause the oil to ignite. Therefore, understanding flashpoints is crucial for both safety during transportation and for the quality of the final product.
Additionally, flashpoints are important for those making gel candles. Using fragrances with flashpoints below 76°C should be avoided as they may combust when they come into contact with gel waxes.

Flashpoints of fragrance oils vary
The flashpoint of fragrance oils varies depending on the oil. For example, eucalyptus oil has a flashpoint of 126° F, while another fragrance oil might have a flashpoint of 200° F. The flashpoint of a fragrance oil is usually listed on the bottle by the supplier.
The flashpoint is important for candle-making as it can affect the strength of the fragrance. If a fragrance oil is added to wax that has been heated above the oil's flashpoint, it can degrade the fragrance, damaging the lighter notes and resulting in a weaker scent. However, adding fragrance oil to wax at any temperature will not negatively impact the scent throw. It is recommended to heat small batches of fragranced wax and pour the candles right away, as heating and cooling the wax repeatedly can weaken the scent.
The flashpoint is also important for shipping fragrance oils. Oils with a low flashpoint, such as those at or below 141° F, cannot be transported by air due to their potential to ignite.

Adding fragrance oil above its flashpoint won't cause combustion
The flashpoint of a fragrance oil is the temperature at which the oil can combust if exposed to an open flame or spark. This is a legal term used to identify which substances can be safely transported on an airplane. It is important to note that the flashpoint is not the temperature at which the oil will "burn off" or begin to dissipate.
When making candles, it is common to add fragrance oil to hot wax. Adding fragrance oil to wax that is hotter than the oil's flashpoint will not cause combustion or affect how strong your candle smells. This is because the properties of the mixture are a blend of both the wax and the fragrance oil, with the wax typically making up about 90% of the blend. However, heating and cooling the fragranced wax repeatedly can weaken the scent. Therefore, it is recommended to heat small batches of wax and pour the candles right away.
It is worth noting that some fragrance oils have lower flashpoints, and these cannot be shipped via air due to their potential to ignite under specific circumstances. For example, fragrance oils with a flashpoint at or below 141° F (60.5° C) cannot be transported by air in the United States. Similarly, Penreco recommends using fragrance oils with flashpoints over 170° F (76.6° C) for gel candles.
In summary, adding fragrance oil above its flashpoint will not cause combustion as long as there is no exposure to an open flame or spark. The flashpoint is a critical consideration for candle makers, especially when working with gel waxes or shipping fragrance oils by air.
