The Most Commonly Used Fragrance Addition Temperature Range in the Industry
Based on extensive practical production experience, when making scented candles using fully refined paraffin wax, 65℃—75℃ is a repeatedly verified and stable temperature range. At this temperature range, the paraffin wax is completely melted and has good fluidity, allowing the fragrance to smoothly integrate into the wax structure without excessive volatilization due to high temperatures.
Many export customers, especially those in the European and American markets, have very high requirements for fragrance stability, and they prefer to control the fragrance addition temperature between 68℃ and 72℃. Junda Wax provides these customers with fully refined paraffin wax specifically for scented candles, optimizing melting and fragrance retention performance around this temperature range to reduce trial and error costs.
Why is a slightly higher temperature more likely to fail?
Some factories believe that a higher temperature makes it easier to mix the fragrance, so they choose to add fragrance at 80℃ or even higher. In the short term, stirring is indeed easier, but this practice is very detrimental to the fragrance. The first components of the fragrance to be boiled off are often the top notes, such as citrus, pine, and floral scents. As a result, the candle smells fine when cold, but becomes monotonous or even dull when lit. When Junda Wax assists customers in optimizing scented candles, we often improve the fragrance layering by lowering the fragrance addition temperature, rather than simply pursuing ease of operation.
Too low a temperature will also worsen fragrance performance.
Of course, lower temperatures are not always better. If the fragrance is added at temperatures below 60℃ or even close to the solidification point, the paraffin wax has already begun to form a crystalline structure, making it difficult for the fragrance to distribute evenly. In this case, the surface may smell fine, but during actual burning, the fragrance will fluctuate in intensity. This is especially true for candles exported to regions with higher temperatures; if the fragrance is unevenly distributed, oil separation or fragrance migration can easily occur during transportation or storage. When serving customers in South America, the Middle East, and Southeast Asia, Junda Wax particularly emphasizes controlling the lower limit of the fragrance addition temperature to ensure consistent fragrance performance in different environments.
Different candle types require different fragrance addition temperatures.
It should be noted that different types of candles do not have the same tolerance for fragrance addition temperatures. Container candles, due to their thicker wax and slower heat dissipation, are relatively more forgiving; however, pillar candles and shaped candles require a higher level of precision in their internal structure, and deviations in fragrance addition temperature can easily amplify problems. When providing a one-stop solution, Junda Wax typically provides more detailed fragrance addition recommendations based on candle type, paraffin melting point, and fragrance load, rather than just a general temperature. This attention to detail often determines whether a batch of goods is barely acceptable or consistently leads to repeat purchases.
Why do export customers care more about fragrance addition details?
Customers in the export market often prioritize consistency and reproducibility of fragrance, rather than one-time fragrance intensity. If the fragrance addition temperature is not consistently controlled, there will be differences between different boxes in the same batch, which is fatal in the retail market.
Many of Junda Wax's long-term partners have gradually established their own standards for scented candles by repeatedly adjusting the fragrance addition temperature and stabilizing the process. This is why they prefer to choose a one-stop supplier that can provide technical support and a complete set of materials, rather than just focusing on price.
What is the optimal temperature for adding fragrance to paraffin candles? If you are using fully refined paraffin and your goal is stable, clean, and reproducible fragrance performance, then 65℃—75℃, especially 68℃—72℃, is currently the most mature and lowest-risk option in the industry.
However, what's truly important is not memorizing a number, but understanding the logic of how temperature affects fragrance performance. Only by considering paraffin characteristics, fragrance type, candle structure, and burning method together can you truly create the desired fragrance. What Junda Wax has been doing is integrating these seemingly scattered details into a practical candle manufacturing solution.
