How the Flashpoint of Fragrance Oils Impacts Candle-Making Success

Flashpoint of fragrance oils and its impact on candle-making performance

The art of candle making requires a keen understanding of various factors, one of which is the flashpoint of fragrance oils. Knowledge of this seemingly technical term holds the key to safety, scent, and overall burn performance of your beautiful creations. Following up on our most discussed post about the art of candle-making, we would like to delve into the matter of flashpoint and how it impacts your craft.

1. Safety

The flashpoint of fragrance oils refers to the temperature at which a particular fragrance oil emits vapors that can ignite momentarily when exposed to an open flame or spark. The key word here is: open flame. To avoid any confusion and misunderstanding, this has nothing to do with pouring temperature. It is all about sources of fire (open flame or spark) that must be carefully monitored in a working space, to avoid any potential ignition.

It’s important to note that if the fragrance is added to wax above the oil’s flashpoint, it will not cause it to combust. However, if the temperature of your wax while pouring exceeds the flashpoint of the fragrance, it can alter the chemical composition of the fragrance. Which leads us to…

2. Scent Retention

The flashpoint of a fragrance oil can also affect the scent retention in a finished candle. Imagine your carefully chosen fragrance burning off in production before gracing the air. That will be disastrous! Adding fragrance at temperatures exceeding its flashpoint can cause volatile top notes to evaporate, leaving behind a weaker scent. Furthermore, the balance of your top, mid, and base notes can be broken, resulting in an altered aromatic output.

Another thing you should have in mind is that fragrance oils with higher flashpoints tend to have better scent retention because they evaporate more slowly during burning, releasing the fragrance gradually over time. On the other hand, fragrance oils with lower flashpoints may evaporate too quickly, leading to a weaker scent throw or even scent loss during burning.

3. Burn Performance

Speaking about scent loss, the flashpoint of fragrance oils can influence the burn performance of candles by a lot (that is why we list it in every product description). Being aware of it can help you create candles that not only smell good but also burn correctly. Furthermore, exceeding it can damage fragrance molecules, impacting the way scent is released throughout the burn. This can lead to an uneven or underwhelming experience.

Fragrance oils with higher flashpoints typically produce a more stable burn with less smoking and sooting. They also tend to allow for a slower and more even release of fragrance throughout the burning process. In contrast, fragrances with lower flashpoints might cause candles to burn unevenly or produce more smoke, affecting the overall user experience.

4. Regulatory Compliance

Lastly, knowing the flashpoint of a fragrance is essential for regulatory compliance. Candle-makers need to comply with safety regulations and guidelines regarding flashpoints set by relevant authorities. And different countries have different regulations regarding the flashpoints of fragrances used in candles. Therefore, being aware of the flashpoint can help you ensure that your candles meet the necessary safety standards.

Thus, before you start selling your fragrant delights, familiarize yourself with local and international shipping regulations to ensure smooth transportation. By mastering the concept of flashpoint, you’ll not only safeguard your crafting sessions but also unlock the full potential of your fragrant creations.

In summary, the flashpoint of fragrance oils is a crucial factor in candle-making, influencing safety during production, the intensity and longevity of scent in the finished product, burn performance, and regulatory compliance. Candle-makers need to select fragrance oils with appropriate flashpoints based on their specific requirements and ensure proper handling and usage to create high-quality, safe candles.

Happy and safe candle-making!
