Creating gel candles involves a unique set of considerations, particularly when adding fragrance. Unlike other waxes, gel wax has a higher melting point, requiring heating to between 110°C and 120°C for a bubble-free result. The ideal pouring temperature is around 60°C. The key factor is adding fragrance at the optimal temperature to ensure it binds with the wax for a strong, even scent. The recommended temperature range for adding fragrance to gel wax is 200°F-220°F (93°C-104°C). This allows the fragrance to dissolve and bind effectively, preventing a cloudy appearance and potential safety hazards. It's crucial to use gel-safe fragrances with a flashpoint above 77°C to avoid instability and unsafe burning. Testing fragrance compatibility with gel wax beforehand is essential for successful and safe candle-making.

Stir the fragrance slowly and allow it to dissolve into the wax
Adding fragrance to gel wax requires precision and patience. Stirring the fragrance slowly and allowing it to dissolve into the wax is a crucial step in creating a beautifully scented and stable gel candle. Here's a detailed guide to help you master this step:
Stirring Fragrance into Gel Wax:
When adding fragrance to gel wax, it's important to stir slowly and with care. Use a heat-resistant utensil to gently mix the fragrance into the melted wax. Avoid vigorous or rapid stirring, as this can create air bubbles or cause splashing. Slow and steady stirring ensures that the fragrance is evenly distributed throughout the wax, resulting in a consistent scent throw.
Allowing Fragrance to Dissolve:
After adding the fragrance, give it time to dissolve completely into the wax. This process is essential for achieving a clear and stable candle. Incomplete dissolution can lead to cloudiness or separation within the gel wax. Take your time and ensure that the fragrance is fully incorporated before proceeding to the next step.
Optimal Temperature Range:
Maintain the gel wax within the optimal temperature range of 200-220 °F when adding the fragrance. Working within this temperature window ensures that the wax is in a suitable state for proper fragrance binding. If the wax is too hot, it can impact the fragrance's performance and safety; if it's too cold, the fragrance may not bind effectively.
Testing Fragrance Safety:
Before stirring the fragrance into the gel wax, it's crucial to ensure that it is gel-safe. Check the solubility and polarity of the fragrance to confirm its compatibility with gel wax. Fragrances with the wrong polarity may not mix well and can cause cloudiness. Additionally, always verify that the fragrance's flashpoint is above 77°C, as gel wax burns at a higher temperature.
Adjusting Fragrance Intensity:
When stirring the fragrance, you can adjust the intensity of the scent by varying the amount of fragrance you add. For a lighter scent, start with about 1/2 teaspoon per pound of wax, and for a stronger scent, increase the amount accordingly. It's important to stir well after each addition to ensure even distribution.

Use a fragrance that is safe for gel wax with a flash point above 77 °C
When making candles with gel wax, it is important to use a fragrance that is safe for gel wax. Not all fragrance oils are suitable for use in gel wax. The flash point of a fragrance oil is significant because gel wax burns at a higher temperature than other waxes. The flash point is the temperature at which the vapours from the oil may ignite if exposed to an open flame.
For gel wax, it is recommended to use fragrance oils with a flashpoint above 77 °C. Using a scent with a lower flash point creates too large a difference between the melt point and flash point, resulting in an unstable and unsafe candle. To test if a fragrance oil is gel wax safe, you can perform the mineral oil miscibility test. Mix one part fragrance to three parts mineral oil in a glass container. If the mixture is transparent and dissolved, the fragrance oil is gel wax compatible. If the mixture is cloudy or insoluble, the fragrance is not gel wax safe.
It is also important to add the fragrance oil at the correct temperature. For optimal results, add the fragrance as close to the pouring temperature as possible. The pouring temperature will depend on the type of wax you are using. However, one source recommends always adding fragrance oil to wax at 185 °F (85 °C), regardless of the fragrance oil's flashpoint. This is because, at lower temperatures, the fragrance may not bind properly with the wax, which can negatively impact the scent throw.
It is worth noting that the flash point of a fragrance oil is not an indicator of how strong the fragrance will be in a candle. The flash point is simply a legal term used to identify which substances can be safely transported on an aeroplane.

Test the compatibility of the fragrance with gel wax using the mineral oil test
To test the compatibility of a fragrance with gel wax using the mineral oil test, follow these steps:
Firstly, it is important to understand the basic procedure for the mineral oil test. This test will determine whether a fragrance oil is polar or not, which will, in turn, indicate its compatibility with gel wax. The test involves mixing a small amount of fragrance oil with mineral oil and observing the behaviour of the mixture.
For the first phase of the test, prepare a clean glass container, preferably a small test tube, and add 3 parts of the synthetic fragrance oil to be tested and 1 part mineral oil. Close the container and shake it vigorously. If the liquid turns cloudy and then clears up again, this is a good sign. Let the mixture rest for a few minutes.
After a few minutes, check the mixture. If the liquid in the test tube has turned cloudy, even slightly, this indicates that the fragrance oil is polar and should not be used with gel wax. If the fragrance oil and mineral oil have separated into two distinct layers, this also indicates that the fragrance oil is polar and incompatible with gel wax.
For the second phase of the test, invert the proportions by using 1 part synthetic fragrance oil and 3 parts mineral oil. Shake and let the mixture rest, as before. Again, if the liquid turns cloudy or separates into two layers, the fragrance oil is polar and should not be used with gel wax.
If the liquid remains clear and no separation occurs, the fragrance oil has passed the mineral oil test and is likely compatible with gel wax. This test ensures that the fragrance oil will not cause cloudiness or separation in the gel wax, which can affect the stability and safety of the final product.
It is important to note that the temperature at which you add fragrance to gel wax is also crucial. It is recommended to add fragrance oil to gel wax at around 185°F (or 85°C) to ensure proper binding and fragrance throw. The pouring temperature will depend on the type of wax, but it is generally advised to add fragrance as close to the pouring temperature as possible for optimum results.

Different grades of gel wax have different fragrance-holding capacities
Candle gel is a nonpolar substance, and only nonpolar synthetic fragrance oils should be added to it. The polarity of a fragrance oil can be determined using a simple test. This is important because if you add a polar fragrance oil to candle gel, the mixture will separate into two layers or become cloudy. Cloudy gel wax is not only unsightly but can also be a fire hazard.
Penreco, the inventor of candle gel, has devised a simple and reliable polarity test. For this test, you need mineral oil and a test tube. In the first phase, add three parts of the synthetic fragrance oil and one part mineral oil to the test tube. If the liquid is clear, this synthetic fragrance oil can be safely used in your gel candles. If the mixture is cloudy or insoluble, the fragrance is not gel-safe.
It is also important to note that different grades of gel wax have different fragrance-holding capacities. Penreco offers three different grades of Versagel candle gel: CLP (Low Polymer), CMP (Medium Polymer), and CHP (High Polymer). Each grade will hold a slightly different amount of fragrance oil. For instance, low-density gel wax can hold up to 0.5 ounces of fragrance oil per pound of wax, while high-density gel wax can hold up to 1 ounce of fragrance oil per pound of wax.
The temperature at which the fragrance is added to the gel wax is also crucial. The ideal temperature range for adding fragrance to gel wax is 200-220 °F. This allows the fragrance to dissolve and bind with the wax optimally. If the gel wax is overheated or underheated, the fragrance will not dissolve properly, causing a cloudy appearance and possibly creating a hazard. Therefore, it is important to use a thermometer to monitor the temperature of the gel wax and add the fragrance slowly, stirring continuously.
