This refers to how much fragrance a particular wax can hold.
If you use more than the recommended amount, you will find that the fragrance oil can separate itself from the wax and “seep” out creating oily spots. It can also create undesirable burning characteristics. **Be sure to reference the particular wax blend that you are using to find out what the maximum fragrance capacity is.
There are different methods for how to calculate a fragrance load. Below are 2 examples on how to calculate fragrance load. For these examples, we will assume we are trying to calculate a 10% fragrance load. Here’s a way to do it.
- Take 16 ounces (16 ounces = 1 pound) to represent 1 pound of wax.
- Multiply 16 by .10 (for the 10%), and you will get 1.6 ounces.
- This means that if a particular wax advertises that it can hold a 10% fragrance load, it should be able to hold approximately 1.6 ounces of fragrance per pound.
- If you use a concentrated fragrance oil with very little solvent, it is likely that you won’t need to use more than 1 ounce per pound of wax (or roughly a 6% fragrance load). This is the usage amount we advise for our fragrances.
Some candle makers will try to be a little more exact with their calculations. So, to take the above example of a 10% fragrance load, another way to calculate it would be:
- 10% of a 16 oz. recipe is 1.6 oz. (of fragrance oil).
- Then you would subtract 1.6 oz. from 16 oz. and actually use 14.4 oz. of wax and 1.6 oz. of fragrance to get the total (of all ingredients) to be 16 ounces.
- In other words, all ingredients would total 100% or 16 oz. Within that grand total, you would have 14.4 oz. of wax and 1.6 oz. of fragrance.
- Of course if you added more ingredients, you would need to re-calculate and add those in to the grand total as well.
Notice in the second (more "exact") example above, the 10% calculation would mean using a little more fragrance per pound than in the first example. Because of this, we typically recommend the first example of calculation to ensure too much oil is not used for the wax blend. It is also a little easier to calculate :)
