How is the scent of a candle formulated, and what factors influence the intensity and persistence of the scent?

The scent blending of candles is a delicate and artistic process that involves the ingenious combination of fragrances, waxes and formulas. Blenders often use a variety of fragrances to create unique and rich fragrances. The base fragrance can be natural plant essential oils or synthetic fragrances, each of which provides different fragrance properties. When blending, the blender will consider the volatility of the fragrance, and usually divide the fragrance into top notes, middle notes and base notes to ensure that the fragrance has a good change during the burning process.

The intensity of the fragrance is affected by several factors. First, the material of the candle is crucial. Natural waxes such as soy wax and beeswax are generally better at absorbing and releasing fragrances, while paraffin wax may not release fragrance effectively. In addition, the concentration of the fragrance is also key. Too low may result in a weak fragrance, while too high may cover up the layers of other fragrances.

The persistence of the fragrance is related to the burning time of the candle and the environmental conditions. The thickness and diameter of the candle will affect the burning speed, thereby affecting the time of fragrance dissipation. Ambient temperature, humidity and ventilation conditions will also affect the volatility of the fragrance. At higher temperatures, the fragrance is easier to release, but in a humid environment, the fragrance may be suppressed.

In addition, the candle making process is equally important. Even mixing and proper cooling process can help the fragrance blend better into the wax and improve the release effect of the fragrance. Therefore, when choosing a candle, understanding the details of its fragrance blending and the materials used can help consumers find products that better suit their preferences.
