How do I weigh fragrance oil?

A good idea when weighing fragrance oil is to use a percentage because you are guaranteed to always get the same results. Most waxes have a 12% maximum fragrance load or approximately 2 oz. per pound. A typical amount is about 6% or 1 ounce per pound. 

The best method is:

  • Use a candle and soap scale for weighing your fragrance oil.

  • Determine how much wax you're going to melt. Let's use 1 lb. (16 oz.) as an example. If you're going to add 6% fragrance oil, multiply 16 x 6% (or.06). You will get .96 which you can round up to 1 ounce.

  • Place a small dixie cup or glass on the scale and "tare" it so that the weight of the cup is removed. You should see 0.

  • Pour 1 ounce of fragrance oil into the cup. Fragrance oil can react to some containers, so don't let the fragrance sit in the paper cup for more than a few seconds and be sure not to use any plastic containers.

  • When the wax reaches the recommended temperature, remove it from heat and add the fragrance. Stir gently and thoroughly.

If you're making a large batch of wax, take the entire amount and multiply it by the percent of fragrance you're adding. For example:

  • If you're making 8-8ounce candles, multiply 8x8=64. Then 64 x 6% (.06) =3.84. You could round that up to 4 ounces of fragrance oil for 64 ounces of wax. If you wanted to add 8% of fragrance oil, then multiply 64 x 8% (.08)=5.12 or about 5 ounces of fragrance oil.
