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. |
