When we talk about essential oil, we think we are using a natural, pure product that is often associated with well-being. We have been able to explain the differences between natural and synthetic perfume , but essential oils have different specificities that you are unaware of . The idea of using essential oils in candles seems attractive, unfortunately it remains dangerous and unsuitable .
They may contain CMRs even though they are a natural product. We explain why.
The presence of CMR substances
Although essential oils are often perceived as safer alternatives to synthetic products, it is important to remember that natural does not necessarily mean safe . Some essential oils can release substances known as CMR (Carcinogenic, Mutagenic or Reprotoxic) when heated to a high temperature, as is the case in a candle.
For example, oils like cinnamon, clove, or lavender can release potentially toxic compounds. You may have thought you were choosing a natural, harmless product, but a natural product is not necessarily safe.
Now that you know some little-known specificities of essential oils, we will explain why you should not use them in your candles.
An ephemeral olfactory rendering
With essential oils, the scent can be inconsistent. These oils are designed to be diffused cold or at low temperatures. When heated by a candle flame, their chemical composition can degrade, reducing the strength of the scent.
Imagine lighting your candle hoping for a pleasant diffusion, and after a few minutes, the scent has already disappeared... This can be frustrating, especially if you have chosen quality, and therefore expensive, oils for this project.
A risk factor: the flash point
Essential oils may seem harmless, but that doesn't mean they're risk-free.
In reality, their flash point (the temperature at which they become flammable) is often low. Using essential oils in candles can increase the risk of accidents , including a risk of ignition if they are incorrectly dosed or if the combustion temperature becomes too high.
A scented candle should be a safe pleasure, and essential oils can introduce a risk factor that is not always suspected.
A composition problem
Essential oils typically lose their scent quickly when exposed to heat , requiring frequent refills without ensuring consistent diffusion. Heat can also alter the chemical composition of some oils, transforming a sweet scent into a harsh, unpleasant odor that is far from the relaxing experience you are looking for.
The biggest drawback is that essential oils don't always mix well with waxes like soy or beeswax, leading to uneven fragrance distribution or even candles that smell almost nothing when lit. It can also affect the texture and burn of the candle, compromising its effectiveness and aesthetic appeal.
Our alternatives to essential oils for your candles
As you will have understood, essential oils are not suitable for use in wax creations , not to mention their cost which can quickly climb, because to obtain a sufficiently present fragrance, it is necessary to use a large quantity.

Although some of these alternatives may be of synthetic origin, they have the advantage of being tested for their safety, effectiveness and exceptional olfactory rendering.
Conclusion
