When it comes to scented candles, the type of wax used can make a big difference in the strength of the fragrance. While there are many types of candle waxes available, paraffin wax stands out for its ability to produce the strongest fragrance. Its excellent scent throw, affordability, and versatility make it a popular choice for commercial candle brands and luxury candles. However, it's important to note that paraffin wax is derived from the oil industry and releases toxins when burned, making it less eco-friendly than other options. If you're looking for a natural and eco-friendly alternative, soy wax, beeswax, coconut wax, and rapeseed wax are great options that also hold fragrances well. Ultimately, the best wax for scented candles depends on your specific needs, preferences, and how strong you like your fragrance.

What You'll Learn
Paraffin wax is the strongest for fragrance throw
Paraffin wax is widely regarded as the best wax for creating candles with a powerful fragrance throw. It is a popular choice for candle-making, particularly for scented candles, due to its excellent scent-carrying properties. Paraffin wax can hold strong fragrances and has a superior scent throw, making it ideal for creating strongly scented candles.
Paraffin wax is a petroleum by-product created from the sludge waste during the refinement of crude oil into gasoline. It is often used in commercial candle products due to its low cost and ability to produce a steady burn. Additionally, paraffin wax is versatile, with various melting points, allowing candle-makers to create different types of candles, from votives to pillars and container candles.
One notable advantage of paraffin wax is its ability to hold fragrances very well, resulting in a strong scent throw. This is because it can carry high fragrance loads and requires less fragrance oil compared to other waxes, making it a cost-effective option for producing scented candles. The use of additives, such as vybar, can further enhance its fragrance retention, although many waxes already come pre-blended with additives.
However, it is important to consider that paraffin wax does have some drawbacks. It releases toxins when burned, including toxic benzene and toluene, which are known carcinogens. Therefore, it may not be suitable for those seeking an eco-friendly or non-toxic option. Additionally, the curing process for paraffin wax typically takes at least 24 to 48 hours, which is significantly shorter than other waxes like soy wax, which requires at least one to two weeks.
While paraffin wax currently offers the strongest fragrance throw, other natural waxes, such as soy, coconut, and rapeseed wax, are continuously improving due to advancements in wax blends and fragrance technologies. These natural waxes are not only eco-friendly and non-toxic but also offer excellent burn performance and fragrance retention, making them increasingly popular alternatives to paraffin wax.

Blended waxes can balance fragrance and burn quality
The type of wax used in candles can significantly impact their fragrance and burn quality. While paraffin wax is the most popular choice for commercial candles, blended waxes offer a versatile, customisable option for candle makers.
Paraffin wax is a petroleum byproduct with a higher melting point, allowing it to hold a higher concentration of fragrance oil. Its simple molecular structure ensures a consistent scent throw, making it ideal for strongly scented candles. However, paraffin wax releases toxins and is not eco-friendly. Soy wax, on the other hand, is a natural, renewable, and budget-friendly alternative. It has a slower burn rate than paraffin, resulting in longer-lasting candles. Soy wax is also known for its excellent scent throw, making it a popular choice for scented candles.
Blended waxes, such as coconut-soy and soy-paraffin blends, offer the best of both worlds. They combine the natural appeal and eco-friendliness of soy wax with the creamy texture and superior scent throw of coconut wax, or the performance benefits of paraffin wax. These blends allow candle makers to customise their creations, fine-tuning the strength of the scent and the burn time. For example, a coconut-soy wax blend provides a natural, luxurious option with a smooth finish and strong scent throw.
The science of blending fragrance oil with wax is critical to achieving the desired balance between fragrance and burn quality. The ratio of fragrance oil to wax is key, typically ranging from 6% to 10%. However, this ratio can vary depending on the type of wax and its fragrance oil capacity. Temperature also plays a pivotal role in the blending process, as fragrance oil must be added within an optimal temperature range to ensure proper integration without evaporation. Additionally, curing time, typically a few days to several weeks, is necessary for the fragrance oils to fully bond with the wax molecules, resulting in a stronger and more consistent scent throw.

Soy wax is a good middle ground for fragrance and eco-friendliness
When it comes to creating scented candles, the type of wax you choose is crucial. While paraffin wax is widely used in commercial candles and is known for its strong fragrance, it releases toxins and is not an eco-friendly option. If you're looking for a balance between fragrance and sustainability, soy wax is a good middle ground.
Soy wax is a natural, eco-friendly wax made from soybeans, a renewable and natural source. It has a number of advantages over other types of wax. Firstly, it burns cleanly and slowly, resulting in a longer burn time compared to paraffin wax. This makes it a more economical choice, as you can enjoy your candles for extended periods. Additionally, soy wax is easy to work with, especially for beginners, as it requires less heat to melt and is simpler to clean up.
Another benefit of soy wax is its excellent scent retention. It effectively carries fragrances, resulting in a pure-smelling candle. When combined with essential oils or fragrance oils, soy wax enhances their aroma and creates a pleasant scent throw. This makes it ideal for scented candles, as the fragrance is released effectively into the air. Soy wax is also known for its versatility. It can be blended with other waxes, such as coconut wax, to create unique candle characteristics and a smoother texture.
While soy wax offers a good balance between fragrance and eco-friendliness, it's important to consider its limitations. Soy wax has a lower melting point than some other waxes, which can cause candles to soften or melt in warmer climates. Additionally, soy wax may produce a "frosting" effect, altering the candle's appearance without affecting its performance. For those seeking decorative candles, palm wax or gel wax may be more suitable, as they offer unique visual effects and transparency.
In conclusion, soy wax is a recommended option for candle makers who want a strong fragrance without compromising eco-friendliness. Its natural and renewable origins, clean-burning properties, and excellent scent retention make it a popular choice. However, it's important to be mindful of its melting point and potential appearance changes. For those seeking the strongest fragrance, paraffin wax remains the industry standard, but advancements in wax blends and fragrance technologies are narrowing the gap and providing consumers with a variety of options to suit their specific needs and preferences.

Coconut wax is a good natural option for holding fragrance
Coconut wax is a fantastic natural option for holding fragrance. It is a newer addition to the candle-making wax market, but it is already making waves for its luxurious properties. Coconut wax is derived from coconuts, a high-yield and sustainable crop, and it burns cleanly with barely any soot. It is also biodegradable and has a slow burn, making it ideal for high-end candles with a strong scent and a luxurious feel.
Coconut wax is a natural, renewable wax that is perfect for candle-making. The process of hydrogenation transforms the oil into a solid form. It has a creamy texture and a smooth finish, making it a preferred choice for artisans and businesses seeking an environmentally friendly option. It is also a good option for those who want to create eco-friendly candles, as it is derived from a natural, sustainable source.
Coconut wax is also a fantastic option for holding fragrance. It has a neutral base, which means it won't interfere with the scent of the fragrance oil you choose to add. This makes it a great choice for those who want to create scented candles with a pure-smelling fragrance. Additionally, coconut wax has a strong scent throw, meaning it can carry fragrances well and provide an excellent scent distribution.
To add fragrance to coconut wax, it is important to follow the correct process. First, melt the coconut wax flakes in a double boiler until they reach a temperature of around 180°F (82°C). Remove the wax from the heat and allow it to cool slightly. Add the fragrance oil when the wax temperature reaches about 140°F (60°C) and stir thoroughly to ensure even distribution. Use 6-10% fragrance oil per weight of wax for optimal scent throw.
Overall, coconut wax is a wonderful natural option for holding fragrance in candles. It has a luxurious feel, burns cleanly, and holds fragrance well. It is a great choice for those seeking an eco-friendly, sustainable option with a strong scent throw. With its neutral base and smooth finish, coconut wax is a fantastic alternative to traditional waxes for candle makers of all experience levels.

Beeswax has a natural scent but may not hold fragrance as well
While beeswax has a natural scent, it may not hold fragrances as well as other types of wax. Beeswax has been one of the most popular candle-making waxes for centuries, and it has a subtle honey scent and signature golden colour. It also has the longest burn time and produces a warm-toned flame that doesn't give off any smoke, benefiting both your home and the environment. However, beeswax does not hold on to scent as well as some other waxes.
Beeswax is naturally fragrant, with a deep aromatic amber fragrance and an intense honey nuance. The wax in the hive is carefully collected by hand and then solvent-extracted. The resulting essence is fully miscible in alcohol and dipropylene glycol, making it easy to work with. The scent is a pleasant, complex composite of honeyed, sweet aspects with floral facets and essences of a musky, intimate ambience reminiscent of sweet hay and cured tobacco.
When making beeswax candles, it can be challenging to add a secondary fragrance. The best temperature to add fragrance to melted beeswax is 160–165°F (about 71–74°C). If the wax is too hot, it will cause evaporation and "burn off" of the scent before the candle is burned. Essential oils should be added at 160–165°F to avoid dissipation, while synthetic fragrance oils can be added up to 180°F or the manufacturer's recommended flashpoint.
To enhance the fragrance in beeswax candles, some people blend a little coconut oil into the wax. Even with the addition of coconut oil, only very strong scents like peppermint, lemongrass, and vetiver do well in DIY beeswax candles. The percentage of fragrance added is also important—while more fragrance might seem better, wax can only hold onto a small percentage (6–12%) of fragrance.
If a strong fragrance is a priority for your candles, paraffin wax is often used in luxury candles and creates the strongest fragrance. It is known for its excellent scent throw and is affordable and versatile. However, it is important to note that paraffin wax releases toxins and is not an eco-friendly option. Other waxes that hold fragrances well include coconut wax and rapeseed wax.
