Why the percentage basis matters
If fragrance is 10% of wax weight, fragrance = wax × 0.10. If it is 10% of the finished mixture, fragrance = finished blend × 0.10.
Batch planning
Use the per-candle amount and quantity to plan a whole pour without manually multiplying each ingredient.
Calculation, not formulation advice
Use the fragrance percentage specified for your actual wax, fragrance, recipe, and supplier guidance.
