Some candles give a rich and evenly diffusing scent even if a large amount of fragrance oil is used, whereas others experience problems such as very strong scent fading after a short time or even unstable burning behavior. Candles with a high fragrance load, i.e., those that are heavily scented, require raw materials that can meet these demanding standards. Therefore, the decision on which paraffin wax melting point to choose is a very important factor. Most well-known brands choose medium-to-high, or even high, melting-point fully refined paraffin wax as there is a strong and logical reason for that. Based on the vast experience of Junda Wax in assisting exports for many years, this finding is not just a story; it is a piece of work validated for a long time.
1. Structural robustness increased: high load of fragrance oils possible
The biggest difficulty in making highly scented candles is how to make the paraffin wax able to contain a higher volume of the fragrance oil without losing the shape and hardness of the structure. A high-melting-point paraffin wax is characterized by a denser molecular structure and hardness. Even though a large amount of fragrance oil has been added, the wax will still have enough rigidity and strength to support the structure.
On the other hand, using paraffin wax with a low melting point and a high content of fragrance can cause the wax to become soft, retain grease and have a slight smell of oil seeping out—these are problems that not only degrade the appearance of the product but can jeopardize its stability when transporting. Junda Wax, when giving paraffin wax suggestions for highly scented items, generally focuses on paraffins with a higher melting point while simultaneously producing a product that can support the structure of the wax with a higher loading of oil.
2. Refrainment of fragrance volatile from wax surface: keeping scent for longer
One of the benefits of using paraffin wax with a high melting point is that it does not heat up quickly when the candle is being burnt. This is because a wax pool is relatively controlled, and the fragrance oil is not going to scatter quickly but can volatilize at a slower and more consistent rate.
This feature is very important for highly scented candles. If the scent is given off very quickly as a result of the fragrance being released rapidly, the candle will emit an extremely strong odor in the first few minutes, and the scent will gradually fade as the candle comes to its midway or final stages, to the extent that the user experience is practically deteriorated. Paraffin wax with a high melting point can give a fragrance the chance to emerge slowly and so cause the fragrance to remain for an extended period.
3. More stable combustion: fewer irregularities in flame
A high level of fragrance will always change the burning process. The consequences can be the flame being unstable, the presence of carbon (soot), or excessive smoke. Such problems associated with the combustion process might be made worse if the paraffin wax is of low melting point. Since paraffin wax with high melting point can ensure more stable combustion and better control of the wax pool, it is to a certain extent capable of neutralizing the negative effects of high fragrance loads. It translates into a flame focused more and a burning that is more uniform. This is the main reason why high-end fragrance brands still choose high melting point paraffin wax while making their highly scented products.
4. More suitable for high-temperature transport environments
High-fragrance candles are also often gift products and premium brand products; therefore, they have to be very presentable and at the same time are more than well-positioned to be sold in international cross-border markets. But high-temperature transportation environments such as those met when shipping to the Middle East, Southeast Asia, etc. impose significantly high requirements on the wax structural stability itself.
High-melting-point paraffin will hardly melt or soften at elevated temperatures therefore, it counteracts problems like deformation and fragrance oil seepage quite effectively. These features help the product to be in a perfect condition when it is finally delivered to the end-user. Junda Wax, having supplied various markets in regions of very high-temperature for many years, focus strongly on transport stability as a deciding factor in product selection.
5. It's not always the case that the higher, the better: it must be in harmony with the entire formulation
First, one of the features of paraffin with a high melting point is that the melting point is really across a range. Once the paraffin wax has been obtained, you may find that the melting point is a little bit higher than what you want but if you describe it, it is not understandable that the candle holder cannot give off the scent as effectively as the candle holder with a melting point slightly lower. So practically, the wax selection in conjunction with the fragrance concentration, wick specs, and overall product positioning is a must.
Many knowledgeable customers have a plan of making use of "high-melting-point paraffin provided a suitable wick or formulation adjustment" to attain the accuracy of their balance. Junda Wax is both a supplier of a wide range of fully refined paraffin waxes of various melting-point ranges, and a one-stop-shop for complementary supplies such as wicks, colorants, and candle making equipment. From a comprehensive point of view, it helps clients in optimizing product performance.
Conclusion
The reason why high-fragrance candles "work" better with high-melting-point paraffin is that high-fragrance candles basically need a very strong support for the structure. Also high-fragrance candles need the combustion process to be more stable and the rate of releasing fragrance be more controlled. The right number of melting points is not only a way to make the fragrance performance better but also it is a very important step to make sure of the stability of the whole product.
Whether you are expanding your candle collection with highly fragranced items or if you are having trouble with your fragrance release during production, we suggest assessing your paraffin wax by melting point again as this may be the key to your success.
