Lauric Acid in Soap

SAP value, how much lye it needs, its fatty-acid profile, and what it brings to a bar.

Lauric Acid has a saponification (SAP) value of 0.2 for NaOH (bar soap) and 0.28 for KOH (liquid soap). It's typically used at 1-10% of the oils.

How much lye for Lauric Acid?

Lye at 0% superfat = oil weight × SAP. Apply your superfat to reduce it (e.g. ×0.95 for 5%).
