Each oil must also be used in a slightly different quantity. Below is a brief list of the many oils that can be used to make soap, the qualities of each, the quantity in which each should be used, and when each should be added to the soap mixture.

Note: Oils indicated for use at the trace stage are superfatting oils, and should not be taken into consideration when calculating lye content for your recipe.
