Substitution factor

NaOH SAP A 0.1770NaOH SAP B 0.1340A / B = 0.1770 / 0.1340

1.3209

Multiply your lye amount by 1.3209 when swapping Palm Kernel Oil for Rice Bran Oil.

Inverse 0.7571 when swapping Rice Bran Oil for Palm Kernel Oil.

500 g swap · pure NaOH

500 g Palm Kernel Oil
88.50 g NaOH
500 g Rice Bran Oil
67.00 g NaOH
Lye_A = Lye_B × factor
