Saponification Value Chart

Calculating lye: multiply the amount of oil/s you are using in ounces by the value for that oil from the chart below.
*Note which hydroxide you’re using. That total is the amount of lye (sodium hydroxide) needed. If using a combination of oils, multiply for each and add all the sums for a the total of all the fats.

Example for Bar Soap: 32 ozs. of olive oil x 0.134 = 4.28 ozs of lye needed.
To calculate water/liquid: Use 6 ozs of liquid per pound (16 ozs) of fat.
Example: 32 ozs of total fats รท 16 = 2 x 6 = 12 oz of liquid.
