How to Calculate Candle Fragrance Load

When making candles, it's crucial to calculate the correct amount of wax and fragrance oil to ensure that your candles provide an optimal burn and a pleasing fragrance. The Candle Fragrance Load Calculator helps you determine these amounts based on the total weight of the candle and your desired fragrance load percentage. Calculating the correct fragrance load is important for both performance and safety, as it ensures an effective scent throw without compromising burn quality or creating potential hazards. Below is a step-by-step breakdown of the formulas involved.

Key Formulas

1. Total Weight (TW)

The total weight of your candle can be estimated using the specific gravity of the wax, which is typically around 0.86 for most paraffin waxes. Note that the specific gravity can vary depending on the type of wax used, which may result in different outcomes. Here are some popular waxes and their specific gravities used for candle making:

  • Paraffin Wax: Specific gravity is around 0.86.

  • Soy Wax: Specific gravity is around 0.90.

  • Beeswax: Specific gravity is around 0.95.

  • Coconut Wax: Specific gravity is around 0.92.

  • Palm Wax: Specific gravity is around 0.89.

  • Gel Wax: Specific gravity is around 0.84.

If you measure the weight of wax that fills your container, you can calculate the total weight (TW) as follows:

TW = Wax Weight × 0.86

2. Wax Weight (W)

Once you know the total weight, you can determine the wax weight (W) by using the fragrance load (f), which is expressed as a decimal. The formula is:

W = TW / (1 + f)

Here, f represents the fragrance load percentage converted into decimal form (e.g., 6% becomes 0.06).

3. Fragrance Oil Weight (FO)

After calculating the wax weight, you can find out how much fragrance oil to add:

FO = W × f

Example Calculation

Different types of wax have different recommended fragrance load percentages for optimal results. For example:

  • Paraffin Wax: Typically 6-10% fragrance load.

  • Soy Wax: Typically 6-8% fragrance load.

  • Beeswax: Typically 5-6% fragrance load.

  • Coconut Wax: Typically 8-12% fragrance load.

Suppose you want to make a candle with a total wax weight of 100 grams and a fragrance load of 6%. Ensure the fragrance load is compatible with both the type of wax and the fragrance oil to avoid separation or performance issues. Here's how you would calculate the required amounts:

  1. Calculate Total Weight (TW)

    TW = 100 × 0.86 = 86 grams

  2. Calculate Wax Weight (W)

    W = 86 / (1 + 0.06) = 86 / 1.06 ≈ 81.13 grams

  3. Calculate Fragrance Oil Weight (FO)

    FO = 81.13 × 0.06 ≈ 4.87 grams

Ensuring Quality Results

By following this process, you can accurately measure the right amounts of wax and fragrance oil, ensuring your candles have an optimal scent throw and burn performance. A 'perfect scent throw' means that the fragrance is evenly distributed throughout the room when the candle is lit, creating a pleasant and consistent aroma without being overpowering. This helps avoid wasting materials and creates a better experience for both the candlemaker and the end user.
