Unraveling The Mystery Of Scented Candles: Fragrance Release

Scented candles are made from wax embedded with a wick and infused with fragrance oils. When a scented candle is lit, the heat from the flame melts the wax, which is drawn up into the wick and vaporised. This process also vaporises the fragrance oils, releasing them into the air as a gas. This is how scented candles release their fragrance.

The heat from the flame melts the wax and evaporates the fragrance oils

When you light a scented candle, the heat from the flame melts the wax and evaporates the fragrance oils, releasing them into the air as a gas. The heat from the flame melts the wax near the wick, and this liquid wax is drawn up into the wick. The heat of the flame then vaporises the liquid wax, turning it into a hot gas. This is also when the fragrance oils mixed into the wax are vaporised. These vaporised molecules rise into the air, where they are detected by your nose as a pleasant aroma.

The heat is essential for transforming the solid fragrance oils into a gaseous form that can be detected by our olfactory senses. The heat from a lit candle accelerates the evaporation process, making the fragrance more pronounced and widespread. This process can also alter the molecular structure of the fragrance oils, which may result in a slightly different scent compared to when the candle is unlit and at room temperature.

A scented candle is composed of three main components: the wax, the wick, and the fragrance. The wax, usually made from paraffin, soy, coconut, or beeswax, forms the body of the candle. The wick, typically made from cotton, paper, wood, or metal, draws the wax towards the flame, enabling the candle to burn. The fragrance is crafted from a blend of essential oils or synthetic aromatic compounds that are carefully selected and mixed to create a specific scent profile.

The molecular structure of fragrance oils can be altered

When a candle is lit, the heat from the flame melts the wax near the wick. This liquid wax is drawn up into the wick where the heat of the flame vaporises the liquid wax, turning it into a hot gas. The fragrance oils mixed into the wax are also vaporised. These vaporised molecules rise into the air, where they are detected by our noses as a pleasant aroma.

The fragrance oils infused in the candle wax are volatile, meaning they can evaporate into the air at room temperature. Therefore, you can still smell a scented candle even when it is unlit. However, the heat from a lit candle makes the fragrance more intense. Sometimes, scented candles may not smell as good when burning compared to when they are unlit.

To prevent the buildup of particulates, it is recommended to limit candle burning time and keep wicks trimmed to 1⁄4” to reduce soot production.

The continuous heat allows for a constant release of scent

When a scented candle is lit, the heat from the flame melts the wax near the wick. The liquid wax is then drawn up into the wick, where the heat of the flame vaporises the wax, turning it into a hot gas. This is also when the fragrance oils mixed into the wax are vaporised. The continuous heat of the flame allows for a constant release of scent, creating a more intense fragrance experience compared to an unlit candle.

The fragrance oils are volatile, meaning they can evaporate into the air at room temperature. Therefore, scented candles can still release their fragrance when they are not lit. However, the heat from a lit candle accelerates this evaporation process, making the fragrance more pronounced and widespread.

The molecular structure of the fragrance oils can be altered by the heat of the flame, which may result in a slightly different scent compared to when the candle is unlit.

The wick draws the wax towards the flame

Heat is essential for transforming the solid fragrance oils into a gaseous form that can be detected by our olfactory senses. The heat from a lit candle accelerates the evaporation process, making the fragrance more pronounced and widespread. This process can also alter the molecular structure of the fragrance oils, which may result in a slightly different scent compared to when the candle is unlit and at room temperature.

The fragrance is crafted from a blend of essential oils or synthetic aromatic compounds

The fragrance of a candle is crafted from a blend of essential oils or synthetic aromatic compounds. These are carefully selected and mixed to create a specific scent profile. When a candle is lit, the heat from the flame melts the wax near the wick. This liquid wax is drawn up into the wick, where the heat of the flame vaporises the liquid wax, turning it into a hot gas. It's at this point that the fragrance oils mixed into the wax also get vaporised. These vaporised molecules rise into the air, where they are detected by your nose as a pleasant aroma. Heat is thus essential for transforming the solid fragrance oils into a gaseous form that can be detected by our olfactory senses.

Technically, scented candles do not have to be lit to release their fragrance. The fragrance oils infused in the candle wax are volatile, meaning they can evaporate into the air at room temperature. However, the heat from a lit candle accelerates this evaporation process, making the fragrance more pronounced and widespread. So while an unlit scented candle can still give off a scent, a lit one will provide a more intense fragrance experience.
