How Much Fragrance Oil Should You Add to Melted Wax for Perfectly Scent Throw?

How Much Fragrance Oil Should You Add to Melted Wax for Perfectly Scent Throw?


Candle making is a rewarding and creative hobby that allows you to craft beautifully scented candles tailored to your preferences. One crucial aspect of candle making is determining the right amount of fragrance oil to add to melted wax. Adding the correct quantity ensures a well-scented candle without overpowering the fragrance or affecting the candle's performance. In this article we'll guide you through the process of calculating the appropriate amount of fragrance oil to create perfectly scented candles.


1. Understand Recommended Usage Rate:

Each fragrance oil has a recommended usage rate specified by its manufacturer. This rate is usually expressed as a percentage of the total weight of the wax used in the candle. It's essential to adhere to this guidance, as it ensures you get the best performance and scent throw from your candles. The recommended usage rate may vary depending on the specific fragrance, so always refer to the product label or the supplier's website for precise guidelines. 

A common amount to use is 6% or 1oz per pound of wax. This can be adjusted up or down depending on the type of wax you're using and personal preference. The maximum amount of fragrance oil recommended is listed in the Properties section of each type of wax.

For example, Golden Brands 464 Soy Wax has a maximum fragrance load of 10% or 1.6 ounces per pound of wax. As each type of wax has different maximum fragrance load percentages, refer to the fragrance information located on the wax information pages or check out our wax guide.


2. Calculate the Amount of Fragrance Oil:

To calculate the amount of fragrance oil to add to your melted wax, you'll need to know the weight of the wax you're using. Multiply the weight of the wax by the recommended usage rate (expressed as a decimal) to obtain the amount of fragrance oil in grams or ounces.

For example, if you have 1pound of wax and the recommended usage rate is 10%, the calculation would be as follows: 1 lb. or 16 ounces (wax weight) x 0.10 (10% as a decimal) = 1.60n ounces of fragrance oil

3. Mix Thoroughly for Even Distribution:

Once you've measured the appropriate amount of fragrance oil, add it to the melted wax and stir thoroughly. Proper mixing ensures that the fragrance is evenly dispersed throughout the candle, resulting in consistent scent throw when the candle burns. Uneven distribution may lead to some areas of the candle being more strongly scented than others.

4. Allow the Wax to Cure:

While your candles may smell fantastic right after adding the fragrance oil, some fragrances may take time to fully develop in the wax. Allow your scented candles to cure for the amount of time required by the wax you chose to use before testing them for optimal scent performance. This curing process allows the fragrance to mature, enhancing the overall aroma of the candle.

5. Key Tips for Success:

  • Always follow the candle supplier's recommended usage rate for each specific fragrance oil you use. Different fragrances may have different rates, so avoid using a one-size-fits-all approach.
  • Overloading the wax with fragrance oil can lead to problems such as poor burning performance, excessive soot, and a weaker scent over time. Stick to the recommended percentages for the best results.
  • Work in a well-ventilated area and follow proper safety precautions when handling fragrance oils and melted wax. Use gloves and protective eyewear if needed.


The amount of fragrance oil you add to melted wax plays a crucial role in creating perfectly scented candles. By adhering to the recommended usage rate, calculating the right quantity, and ensuring thorough mixing, you can enjoy well-balanced and delightful scents in your handmade candles. Remember to let your candles cure for optimal fragrance development. With these tips, you're well on your way to becoming a master candle maker, delighting your senses and those of your loved ones with beautiful, aromatic candles. Happy candle making!
