I want to set some things right with people who might also be confused about 10% fragrance load…
Most people are taught that 1 oz of FO per pound of wax is correct. It is NOT correct as it is written if you want a candle with 10% fragrance load..
The concentration of fragrance oil in a candle is usually measured by the percentage of fragrance oil in relation to the TOTALweight of the FINISHED CANDLE. For example, a candle with a 10% fragrance load would contain 10% fragrance oil and 90% wax. 10+90=100%
A 16-ounce candle (1 pound) is 90% wax and 10% fragrance oil. Using a full pound of wax would be 100% of the candle weight. You can’t make a 16-ounce candle with 16 ounces of wax unless its unscented, because if you add anything above 16 ounces you will have more material than you do candle.
If you add 1 ounce of fragrance to 16 ounces of wax, you will note that’s not even 10% as there are 16 ounces in a pound 10% would be 1.6 ounces. If you follow the popular method, you are getting between 6-7% at BEST. Which is the recommended amount of fragrance for most candles and somewhere people just assumed that was 10%. It is clearly not.
I made this chart so you can see what 10% fragrance load looks like and utilize it for your own best candles.
EDIT: Added a chart with grams. Im not very good with the metric system so I used a calc. If there is any tiny descrepency it will be unoticeable.
