What does flash point mean in candle making

Candle making can be a fun, creative, and surprisingly easy hobby to get into. However, it can also be a little daunting, especially if you are new to the craft. One term you may hear often in the candle-making world is “flash point” and it’s often misunderstood. Some candle makers believe that the flashpoint is the temperature at which the scent will dissipate or “burn off” when it’s added to wax, but this isn’t actually true. So what is a flash point, exactly?

What is a flashpoint?

Simply put, a flashpoint is a temperature at which the vapor from the fragrance oil can ignite when exposed to an open flame. This may sound scary, but it’s important to remember that this doesn’t mean the oil will definitely ignite at that temperature – it just means that it’s possible. There needs to be an open flame for ignition to occur and not just something hot.

If you are heating up a pot of pure fragrance oil, for example, and the oil reaches its flash point, the vaporized oil could potentially ignite and cause a fire if an open flame or spark was placed close to the surface of the oil.

Do fragrance oils with low flashpoint burn off?

It is important to know that you can safely add low flashpoint fragrance oils to your wax up to temperatures well above the flash point without any risk of ignition. In addition, the low flashpoint fragrance oils do not burn off or degrade. This means that you can add them to your wax without worrying about them evaporating. As long as you pour the wax soon after adding the fragrance, the scent will not lose strength. Flashpoint has literally nothing to do with the performance of your candle’s fragrance.

Instead, there are a few things to keep in mind when it comes to ensuring your candles smell as strong as possible. In addition to heating and cooling wax repeatedly, other mistakes that can lead to weak-smelling candles include using too much or too little fragrance oil and using an incorrect wick size. If the wick is too small, it won’t be able to burn hot enough to release the fragrance from the wax. On the other hand, if the wick is too large, it could cause the wax to melt too quickly, which will also affect how strong your candles smell.

When do flash points matter?

There are two reasons why flashpoints are listed on fragrance oils:

  1. While the majority of candles are made from paraffin and vegetable waxes, there are candles that are made from candle gels. Candle gels are specially formulated for candle making and are made with 95% mineral oil and 5% polymer resin. These candles can burn for twice as long as paraffin candles and they also create some unique designs. However, it is crucial to add only nonpolar fragrance oils with flashpoints over 170°F to candle gels.
  2. Under the law, any flammable liquid (including fragrance oils) with a flashpoint at or below 141° F cannot be transported by air. This is because they might ignite under certain circumstances, which we discussed before. Fragrance oil that falls into this category is shipped via ground instead.

I hope this article has helped to clear up any misconceptions you may have had about flashpoints. While it is an important factor when making gel candles or shipping fragrance oil by air, for most other applications, it is not something you need to worry about.
