How to Convert Oven Recipes to Air Fryer
Fragrance oil is added as a percentage of the wax weight. The maximum safe fragrance load depends on the wax type.
The basic rule:
- Fragrance oil (oz) = wax weight (oz) × fragrance percentage / 100
- Total batch weight = wax weight + fragrance oil weight
- Soy wax typically holds 6–10% fragrance load
- Paraffin wax can hold up to 10–12%
- Beeswax holds less fragrance — typically 3–6%
Adding more fragrance than the wax can hold causes sweating (oil pooling on the surface), poor burn, and potential wick clogging. Always test your specific wax and fragrance combination.

Frequently Asked Questions
What fragrance percentage should I use?
For soy wax, 6-10% is typical. Start at 6% for subtle scent and increase to 8-10% for strong hot throw. Never exceed your wax manufacturer's recommended maximum, as excess oil won't bind to the wax.
What is hot throw vs cold throw?
Cold throw is how a candle smells unlit. Hot throw is the scent when burning. Good hot throw requires proper fragrance load, correct pouring temperature, adequate cure time (1-2 weeks for soy), and appropriate wick size.
Can I use essential oils instead of fragrance oil?
Yes, but essential oils are generally weaker in candles and more expensive. Use the same percentage calculations. Some essential oils like citrus have low flash points and may not perform well. Always check flash point ratings.
What is the flash point and why does it matter?
Flash point is the temperature at which fragrance oil can ignite. Add fragrance oil to wax that has cooled below the oil's flash point (typically 170-200°F). Adding to hotter wax burns off the scent and is a fire risk.
