Saponification Value Chart for Sodium Hydroxide

The chart below lists SAP values for commonly used oils in soapmaking.
To calculate the required amount of lye (sodium hydroxide) needed, multilpy the amount of oil you are using in ounces (wt.) by the SAP value for that oil from the chart below.
If you are using a combination of oils, calculate the necessary amount of lye for each oil and add the sums of each lye calculation for a total amount of lye required.

Example: 32 ozs. of olive oil x 0.134 = 4.28 ozs of lye needed.
To calculate water/liquid needed: Use 6 ozs of liquid per pound (16 ozs) of oil.
