It is very crucial that you are determining these optimum use prices by weight, using an accurate scale (I 'd recommend exact to at least 0.01 g).

Claim a recipe calls for 3g of menthol, and your peppermint important oil (United States/ Canada) is 50% menthol.

You are, of course, additionally bringing an extra 3g of various other pepperminty things to the recipe that were not initially accounted for when the formula was developed.
