Scented candles have become increasingly popular in recent years, essentially becoming a key element in creating a pleasant ambiance in any home. If you frequently buy scented candles, you might have noticed that some candles retain their fragrance even after half an hour, while others fill a room with a wonderful aroma in just three minutes. This is closely related to the candle's main ingredients. Especially Fully Refined Paraffin Wax, which is widely used in daily life, how well does it perform in terms of fragrance diffusion? Why do so many export brands specify the use of Fully Refined Paraffin Wax produced by Junda Wax?
The Main Raw Materials of Scented Candles
Whether a scented candle smells good, how long it smells, and whether the fragrance release is stable all depend on the "wax base." Common wax bases include soy wax, coconut wax, beeswax, and paraffin wax. Among these, Fully Refined Paraffin Wax is one of the most widely used basic raw materials in global scented candle manufacturing due to its reasonable price, low impurity content, and strong compatibility. Especially in the Southeast Asian, Middle Eastern, Eastern European, and South American markets that Junda Wax exports to, scented candle factories generally prioritize using Fully Refined Paraffin Wax.
Fully Refined Paraffin Wax has a high melting point, moderate hardness, and high whiteness, and its stable structure makes it less likely to affect the scent of the fragrance itself. This makes Fully Refined Paraffin Wax particularly suitable for making scented candles that require "long-lasting fragrance diffusion." In addition to supplying Fully Refined Paraffin Wax with different melting points, Junda Wax also provides a complete set of raw materials for scented candles, such as wax threads compatible with different fragrances, heat-resistant and colorfast dyes, and scented candle production equipment, allowing customers to truly achieve "one-stop shopping."
How are scented candles made?
The process of making scented candles seems simple: melt wax → add fragrance → stir → pour wax → cool. However, many details affect the diffusion of the fragrance. For example, if the fragrance is heated to too high a temperature, it will evaporate too quickly; if too little fragrance is added, it won't be fragrant enough; if too much is added, it can cause the candle to have dents and oil seepage on the surface. Another example is choosing the wrong wax wick; if the burning temperature is insufficient, the fragrance won't evaporate at all. Some small factories even find that the scent is completely gone after pouring it out, which is actually due to improper mixing of raw materials and proportions.
Fully Refined Paraffin Wax plays a crucial role in this process. Its relatively regular crystal structure can "encapsulate" the fragrance, preventing it from easily evaporating before the candle is lit; however, when the candle burns, Fully Refined Paraffin Wax can release the fragrance at the appropriate temperature, allowing the scent to diffuse more stably and evenly.
Why does Paraffin Wax Fully Refined offer more stable fragrance diffusion?
Unlike regular paraffin wax, Paraffin Wax Fully Refined has a lower oil content, fewer impurities, a purer white color, and a more uniform structure, making it exceptionally stable in the scented candle industry. Junda wax's fully refined paraffin wax typically has an oil content below 0.5%, with melting points controlled within the most commonly needed ranges: 58–60°C, 60–62°C, and 62–64°C. These specifications are the most popular among scented candle factories exporting to markets such as Vietnam, Malaysia, the Philippines, Turkey, Brazil, and South Africa, as they are compatible with most fragrance types.
Paraffin Wax Fully Refined has a dense structure, allowing it to effectively "lock in" the fragrance, preventing excessive evaporation during the waxing process. Furthermore, its uniform melting rate during burning prevents localized overheating, resulting in more even fragrance diffusion and avoiding the unpleasant situation of "fragrant for the first 10 minutes, then fading away."
Junda wax also recommends different melting points based on the type of candle the customer chooses: For container candles, Paraffin Wax Fully Refined melting point is generally selected at 58–60°C; for column candles, which are harder, Paraffin Wax Fully Refined melting point is required at 60–64°C; and for scented candles, Paraffin Wax Fully Refined melting point is generally selected at 58–62°C for optimal performance. These experiences are the culmination of Junda wax's years of service to candle factories worldwide.
The Real Performance of Paraffin Wax Fully Refined in Fragrance Diffusion
Different fragrances have different volatility levels. For example, citrus and mint fragrances diffuse more easily, while woody and resinous fragrances diffuse more slowly. The advantage of Paraffin Wax Fully Refined is that it allows both types of fragrances to maintain a relatively balanced diffusion state. Many of our clients who make high-end scented candles mix natural essential oils with synthetic fragrances and have found that Paraffin Wax Fully Refined maintains a stable fragrance release, even resulting in a fuller "tail" after the candle is lit.
Some international clients (especially from South America and the Middle East) make very strong-scented candles. If the wax base is unstable, strong fragrances can easily cause surface seepage or candle dents. We recommend Paraffin Wax Fully Refined, which has a higher melting point, along with a suitable thicker wax thread and a specific stirring temperature, and the problem is solved.
Junda wax offers a one-stop supply of candle raw materials.
Fragrance diffusion relies not only on Paraffin Wax Fully Refined, but also on the overall blend. Junda wax exports not only fully refined paraffin wax to global customers, but also: Wax threads of varying thicknesses (affecting burning temperature and fragrance release speed) High-temperature dyes that do not change color Fragrances compatible with paraffin wax systems, A complete set of production equipment including automatic wax filling machines, mixers, demolding machines, and cooling platforms. Many customers previously experienced poor fragrance diffusion due to wax threads that were too thin, melting pool areas that were too small, excessively high stirring temperatures causing fragrance evaporation, or even rapid mold cooling leading to unstable wax structures. We provide advice based on our customers' candle fragrance positioning, target market, and even climate conditions, helping them truly create "more fragrant, longer-lasting, and more competitive" scented candles.
While there are now environmentally friendly waxes such as soy wax and coconut wax on the market, Paraffin Wax Fully Refined remains the most commonly used wax base for scented candles globally. It is reasonably priced, has a stable supply, strong compatibility, and excellent fragrance diffusion performance, making it particularly suitable for large-scale production and export-oriented candle factories. Whether you prefer a light, medium, or heavy scent, Fully Refined Paraffin Wax consistently delivers a remarkably consistent fragrance.
