Soap Oils SAP Saponification Values Factors

The SAP values below are set to 1% excess fat. To calculate how many ounces of lye are needed for the oil that you use take the ounces and multiply by the factor. Sodium Hydroxide is the lye you would use for bars of soap. For more excess fat you would decrease the lye a fraction. For every percent that you want to increase the excess fat just reduce the lye by 1%. For example to make a batch go from 1% excess fat to 2% you would multiply the lye by .99. Make sure you reduce the lye. Do not increase it. There are also values below for Potassium Hydroxide which is what is used to make liquid soap. (Note – most of the oil names below are clickable and will give you pricing on the different oils)

Disclaimer – double check your SAP values with other sources to make sure there are no mistakes.  To do this use google and type in the oil name and the word SAP.  We have tried to make sure all the numbers are accurate but can make no guarantees.  Quite often you will see sites with different numbers and the reason is that they are using a different excess fat percentage.  You mainly want to make sure that you do not use too much lye.
