Accurately weighing out fragrance oils is essential when making multiple candles to ensure consistency throughout and one way to achieve this is to use percentages. Generally, you will be looking to achieve a 6% fragrance load but would not want to exceed 12% for most waxes. You will need a set of sensitive high accuracy digital scales.

How to weigh Fragrance Oil

  • Use only a set of dedicated candle scales for the job
  • How much wax do you need to melt? (250g)
  • Place a small cup on the scales and set to zero
  • Pour 7% of fragrance into your cup (17.5g)
  • Only when your wax has reached the desired temperature, remove from the heat and pour in your fragrance, stirring gently
  • For large batch quantities, take the total and multiply it by the percentage of fragrance being used:

For example,

If making 8 candles each using 250g of wax with 7% fragrance,

250g x 8 = 2000grams of wax

2000 x 0.07 = 140grams of fragrance

If you needed to increase the amount of fragrance oil to 12% (the highest recommended amount) these would be your calculations,

250g x 8 = 2000grams of wax

2000 x 0.12 = 240grams of fragrance
