How to Calculate Candle Fragrance Loads

Achieving a balanced and safe hot scent throw requires calculating pure botanical or aromatic oils relative to the metric physical weight mass of your solid wax medium.

6% to 8%: Standard concentration for maximum stability in natural soy and paraffin profiles.
10%: High-intensity limits designed exclusively for specific complex vegetable oil applications.

Frequently Asked Questions (FAQs)

How much fragrance oil do I need for 1 pound of soy wax?

For 1 pound (16 ounces) of soy wax using a standard 6% fragrance load, you will need exactly 0.96 ounces of fragrance oil. If you want a stronger scent throw at an 8% load, you will need 1.28 ounces of oil per pound of wax.

What is the standard fragrance load percentage for candle making?

The industry standard for premium hand-poured candles ranges between 6% and 8%. While some advanced natural waxes can tolerate up to a 10% maximum load, exceeding this limit can cause structural sweating, cracking, or poor flame burning characteristics.

Do I measure candle wax and oil by weight or liquid volume?

Always measure both your solid wax components and concentrated liquid fragrance oils by physical weight mass (grams or ounces) using a digital scale. Liquid volume fluid ounces do not accurately equal weight ounces due to specific material density variances.
