Over 12%! Most candle waxes max out around 10-12% fragrance load. Exceeding it causes sweating, poor burn, and weak scent throw. Reduce your target percentage.
Heads up: under 3% fragrance load usually gives weak scent throw. Most makers use 6-10% for a strong-smelling candle.
Wax weight = water weight times 0.86 (wax is less dense than water). Fragrance load is measured against wax weight, matching our Fragrance Load Calculator. Milliliter conversions assume a typical fragrance oil density of 0.95 g/ml — check your supplier’s spec sheet for exact figures. Always confirm against your wax supplier’s maximum fragrance load.
