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%).
| Lauric Acid | NaOH (0% SF) | NaOH (5% SF) | KOH (0% SF) |
|---|---|---|---|
| 100 g | 20 g | 19 g | 28 g |
| 250 g | 50 g | 47.5 g | 70 g |
| 500 g | 100 g | 95 g | 140 g |
