Do wax melts evaporate - a complete guide 2023

July 06 2023 – Oh My Melt

Wax melts have gained tremendous popularity as an alternative to traditional candles. They come in various shapes, colors, and scents, creating a pleasant ambiance and filling the air with delightful fragrances. As a wax melt enthusiast, you might wonder, "Do wax melts evaporate?" In this complete guide, we will explore the science behind wax melts and explain how they release fragrance into the air.

Understanding Wax Melts:

Wax melts are small pieces of wax, often shaped like cubes or other decorative forms. They are typically made from a blend of waxes, such as paraffin, soy, or beeswax, mixed with fragrance oils. Unlike candles, wax melts do not have a wick and are designed to be melted using a heat source, such as a wax warmer or a tealight burner.

The Science of Wax Melting:

When heat is applied to a wax melt, the wax begins to melt and turn into a liquid state. This process is called melting point, which is the temperature at which the solid wax transforms into a liquid. The melting point of wax can vary depending on the type of wax used.

Evaporation of Fragrance:

As the wax melt heats up and melts, the fragrance oils blended within the wax also begin to vaporize. These fragrance oils have lower boiling points compared to the wax itself, allowing them to evaporate at lower temperatures. As the fragrance oils vaporize, they release the aromatic molecules into the surrounding air, creating a pleasant scent in the room.

The Role of Heat Sources:

To melt wax melts, you need a heat source. Wax warmers are commonly used for this purpose. They typically consist of a heating element or a tealight candle placed beneath a dish where the wax melt is positioned. The heat generated by the heat source raises the temperature of the wax, causing it to melt and release the fragrance.

Duration of Wax Melt Fragrance:

The longevity of the fragrance in wax melts depends on various factors, including the quality of the fragrance oil, the amount of oil used, and the duration of the heat source. High-quality fragrance oils tend to have a stronger scent throw and can last longer. Similarly, using an appropriate amount of wax melt and maintaining a consistent heat source will help prolong the fragrance experience.

Tips for Maximizing Fragrance Release:

To make the most of your wax melts and ensure a lasting fragrance, consider the following tips:

1. Quality Wax Melts: Choose reputable brands that use high-quality wax and fragrance oils.

2. Proper Wax Melter: Use a wax warmer or burner specifically designed for wax melts to ensure safe and efficient heating.

3. Suitable Heat Source: Opt for a heat source that provides consistent and controlled heat, such as an electric wax warmer.

4. Appropriate Wax Amount: Use the recommended amount of wax melt for your specific wax warmer. Overloading the dish can hinder proper fragrance release.

5. Cleaning and Replacing: Clean your wax warmer regularly to prevent any residue buildup. Replace the wax melt once the fragrance diminishes, typically after several uses.


Wax melts do indeed evaporate, releasing fragrance into the air when heated. Although there is wax left behind, at the end this will have minimal or no scent left. By understanding the science behind wax melting and following proper usage guidelines, you can enjoy long-lasting and delightful aromas in your living spaces. Remember to choose high-quality wax melts and maintain suitable heat sources for the best fragrance experience.
