How is fragrance measured in candles?

Fragrance in candles is typically measured in terms of fragrance load, which is the percentage of fragrance oil relative to the total weight of the wax. This load usually ranges from 5% to 15%, depending on the type of wax and desired scent strength. Additionally, the "throw" of the fragrance—how well it disperses in a room when lit—can be assessed through testing in various environments. Manufacturers often conduct sensory evaluations to ensure the fragrance meets quality and intensity standards.
