Palmitic Acid has a saponification (SAP) value of 0.153 for NaOH (bar soap) and 0.215 for KOH (liquid soap). It's typically used at 2-15% of the oils.
How much lye for Palmitic Acid?
Lye at 0% superfat = oil weight × SAP. Apply your superfat to reduce it (e.g. ×0.95 for 5%).
| Palmitic Acid | NaOH (0% SF) | NaOH (5% SF) | KOH (0% SF) |
|---|---|---|---|
| 100 g | 15.3 g | 14.5 g | 21.5 g |
| 250 g | 38.3 g | 36.3 g | 53.8 g |
| 500 g | 76.5 g | 72.7 g | 107.5 g |
