First you'll need to know what percentage of fragrance oil you want to use. The average usage is 6%, please see our FAQ for more information to help determine how much to use with your particular wax.
Here is a simple formula:
(oz of wax using) x (% of fragrance oil you want to use) = (oz of fragrance oil needed)
For example, lets say you are using two pounds of wax and want to use 6% fragrance oil.
First you'll need to calculate the number of ounces of wax you have:
2 x 16 (number of oz in 1 pound) = 32oz
Plug these numbers into your formula:
32 x 6% = 1.92oz
You can round up to 2oz for easy measuring.
