In candle making, the fragrance load is important. This value will vary to some degree, on the various components of your candle system, which is why it is often given as a range. So, what is the fragrance load? Generally, it is the percentage of fragrance oil recommended for a particular wax.
There are several reasons why fragrance load matters.
As you determine the percentage of fragrance you will use in your candle system, there are several important things to consider. Most of these will require testing so that you can compare the hot throw performance of your different percentages. (If you haven’t already grabbed our testing template, you should!)
Not all waxes are created equal: Be sure to look at the fragrance load or suggested range of fragrance load for the specific type and brand of wax you plan to use. See the different characteristics of the waxes we carry.
Are you using any additives? Additives have the potential to impact fragrance load determination in two ways. If you’re using something that adds volume to your system/formula, you’ll want to include that in your calculation. If your additive has an impact on rate of formation of melt pool, it may prompt you to adjust your percentage in response.
Wick choices: Different wicks have different burning characteristics and will have an impact on the rate at which your melt pool is created…and how much fragrance you will want. See the different characteristics of the wicks we carry.
Fragrance Characteristics & Desired Throw: Some fragrances naturally exhibit stronger hot throws than others. You will need to determine what strength of throw you want for each fragrance. You may also find that the throw will vary depending on the diameter of your vessel/melt pool as the larger it gets, the more surface area available. Learn more about the TruScent Fragrance Oils.
FYI – When we test fragrances in-house during as part of our process to determine which ones we want to carry, we use C-3 wax and a 6% fragrance load. During the evaluation, we consider the hot throw along with other less quantitative observations. Since this is our benchmark, we’d suggest this as a good place to begin your testing process. Since some fragrances are simply much stronger than others, if you know that you want a stronger throw, you may want to test at 6% and at a slightly higher % so that you can see if the increased fragrance actually makes a noticeable enough difference.
