How much fragrance oil to use in your candle?

The exact fragrance load to use depends on the type of wax, the type of fragrance and personal preferences. Candle making involves testing and experimenting until you find that sweet spot where it all comes together. 

Using too little fragrance may result in a low scent throw, while using too much fragrance may overload the wax and cause sweating or curdling. 

The recommended fragrance load to use for a soy wax candle is generally between 5% to 10% of the weight of the wax used in the candle. 

The general formula is:

[Weight of wax] X [fragrance load %] = weight of fragrance oil to add

Example for a 6 oz candle container:

4 oz of wax X 8% fragrance load  = 0.32 oz fragrance oil

The table below shows the the weight of fragrance oil to add for the candle tins in our candle making kit. This can be a guide if you want to experiment with making individual candles one at the time.
