How Much Fragrance Oil Do I Add to a Candle?

One of the most common questions in candle making is: how much fragrance oil for a candle is the right amount? Using the correct ratio ensures a well-scented, clean-burning candle. Too little fragrance oil may result in a weak scent throw, while too much can cause burning issues. This guide will help you understand the ideal fragrance oil amount for candles and how to calculate it properly.

Disclaimer: When using essential oils or fragrance oils in candles, always check with the International Fragrance Association (IFRA) guidelines to ensure safe usage levels and proper handling.

Understanding Fragrance Oil for Candles

Fragrance oil for candles plays a crucial role in determining the strength and quality of a candle’s scent. The amount of fragrance oil per pound of wax is measured as the fragrance load, which refers to the percentage of fragrance oil relative to the wax weight.

The most common fragrance loads for candles range from 6% to 10%, though some wax types can handle up to 12%. Using the appropriate fragrance oil for candle making ensures that the scent binds well with the wax for optimal performance.

Factors That Impact Adding Fragrance Oil to Candles

Several factors influence how much fragrance oil for candles should be used:

  • Type of Wax – Different waxes hold varying amounts of fragrance oil. For example:

    • Soy wax typically holds 6-10% fragrance oil.

    • Paraffin wax allows up to 12% fragrance oil.

    • Beeswax has a lower fragrance load capacity, around 3-6%.

  • Candle Size – The total wax weight affects how much fragrance oil per pound of wax is needed

  • Fragrance Oil Strength – Some fragrance oils for candle making are more potent than others. Lighter scents, like citrus or floral, may require a higher fragrance load, while stronger scents, like vanilla or musk, need less.

  • Flashpoint of Fragrance Oil – Each fragrance oil for candles has a flashpoint, which is the temperature at which it begins to evaporate. Adding fragrance oil at the right wax temperature (typically 185°F for most waxes) ensures maximum scent retention.

How Do You Calculate Fragrance Load for Candles?

To determine the fragrance oil amount for candles, use the following formula:

(Wax weight) × (Fragrance load percentage) = Fragrance oil amount

For example, if you're using 1 pound (16 oz) of wax with an 8% fragrance load:

16 oz × 0.08 = 1.28 oz of fragrance oil

For different wax amounts:

  • 1 lb of wax at 6% → 0.96 oz fragrance oil

  • 1 lb of wax at 10% → 1.6 oz fragrance oil

  • 2 lbs of wax at 8% → 2.56 oz fragrance oil

Using this method ensures that you’re adding fragrance oil to candles at the correct ratio, preventing issues like weak scent throw or wick clogging.
