The Candle Making Formula

When making your own candles, understanding the right proportions of wax to fragrance oil is crucial for achieving the perfect aroma and burning performance. Typically, fragrance load—the concentration of fragrance oil in the wax—ranges from 6% to 10%, but this can vary depending on the type of wax and fragrance used. For example, soy wax generally accommodates up to 10% fragrance load, making it a popular choice for strong, lasting scents. Paraffin wax might have a slightly different capacity and behavior. To calculate the exact amount needed, weigh your wax, then multiply by the desired fragrance load percentage. For instance, for 500 grams of wax and a 7% fragrance load, you would add 35 grams of fragrance oil. It is also important to consider the fragrance’s flash point—its temperature at which it evaporates—because adding fragrance oil at too high a temperature can degrade the scent. Most candle makers add fragrance between 65-75°C (150-170°F) after melting the wax. Another factor is the type of wick you choose; different wicks burn differently and affect how the scent disperses. Thicker wicks may require more wax and may enhance fragrance throw, but this should be balanced with the fragrance load. Testing small batches with varying fragrance loads and different wax types can help find the best combination for your desired candle characteristics. Keep notes for consistency in future projects. By carefully measuring and balancing wax and fragrance, you can create beautifully scented candles that burn evenly and delight the senses. This formula is a handy reference for both beginners and experienced candle makers aiming to perfect their craft.
