Which Essential Oils Are Flammable?
Essential oils have been used for centuries for their various therapeutic properties. They are often diffused into the air, applied topically, or added to bathwater to promote relaxation, alleviate stress, and improve overall well-being.
However, while essential oils are generally safe, it’s important to be aware of their potential hazards.
One of the most significant risks associated with essential oils is their flammability. This article will explore this topic in more detail and provide some vital information to remember when using essential oils.

What Are Essential Oils?
Essential oils are natural, volatile liquids that are extracted from plants. They are highly concentrated and possess the characteristic fragrance and properties of the plant from which they are derived.
Depending on the plant material, essential oils are obtained through distillation, cold pressing, or solvent extraction.
These oils comprise diverse chemical compounds, including terpenes, alcohols, esters, aldehydes, and phenols.
The unique combination of these constituents gives each essential oil its distinct aroma and potential therapeutic benefits.
Essential oils have been used for centuries in various traditional systems of medicine, such as Ayurveda and traditional Chinese medicine, for their potential healing properties.
They are also widely used in aromatherapy, which involves inhaling or topicalizing essential oils to promote physical, emotional, and mental well-being.
Factors Affecting Flammability of Essential Oils
Several factors influence the flammability of essential oils. Understanding these factors is crucial for safe handling and storage. The main factors affecting the flammability of essential oils include:
Flash Point: The flash point is the lowest temperature at which a substance gives off vapors that can ignite when exposed to an open flame or heat source. Essential oils with lower flash points are more flammable than those with higher ones.
Volatility: Volatility refers to the tendency of a substance to evaporate at a given temperature. Essential oils with high volatility evaporate quickly and are more likely to ignite when exposed to a flame or heat source.
Chemical Composition: The chemical composition of essential oils plays a significant role in their flammability.
Some essential oils contain chemical constituents that are highly flammable, such as alcohols, aldehydes, or ketones. The presence and concentration of these flammable compounds can affect the overall flammability of the oil.
Oxygen Content: The presence of oxygen can influence the flammability of essential oils. Essential oils can contain oxygenated compounds that can contribute to the ease of ignition and sustain combustion.
Contaminants: Contaminants or impurities in essential oils, such as water or other volatile substances, can affect their flammability. These impurities can lower the flash point and increase the risk of flammability.
It’s important to note that while some essential oils may have flammable properties, their typical use involves dilution and dispersion, significantly reducing the risk of flammability.
However, when handling essential oils in concentrated form or in situations involving heat or open flames, it is essential to exercise caution and follow appropriate safety measures to prevent accidents or fires.
