How much fragrance do you put in a candle?

When it comes to figuring out how much candle fragrance to use you need to know the fragrance load of your candle wax first. Most candle wax makers will include this on the label and/or in the description of the product. Soy wax, for example, can hold fragrance better than paraffin. 

The second step is choosing your desired fragrance load within the capabilities of the candle wax. Store-bought candles have a common fragrance load of 6%. Whereas high quality, handcrafted candles can have a fragrance load up to 12% depending on the wax blend. 

Take for example this pure soy wax has a maximum fragrance load of 10%. You could choose to make a fragrance load anywhere between 6 and 10 percent working with this wax.

Once you have these numbers you can put them to use with a fragrance load calculator and calculate the fragrance load for your homemade candle!

What temperature do you add fragrance to candle wax?

When you are making candles with natural fragrance oils this step is easy to figure out, because the flashpoint of the oil is listed on the label.

However, if you are using essential oils to fragrance candles, you won’t likely find a flashpoint listed anywhere. So, to keep the scent from evaporating a.k.a. burning off add essential oils at a very low temperature of 120 to 125 degrees Fahrenheit.
