Tucuma Butter for Soap Making
Tucuma Butter is a hard butter dominated by lauric (48%), myristic (23%), oleic (13%). Very high in lauric and myristic acids, it makes a hard, fast-lathering bar but is drying on its own, so most makers pair it with conditioning oils.
Quick Facts
How Much Lye for Tucuma Butter?
With a SAP value of 0.170, fully saponifying tucuma butter takes 0.170 grams of sodium hydroxide per gram of oil (at 0% superfat):
| Oil amount | NaOH (0% superfat) | KOH (liquid soap) |
|---|---|---|
| 100 g | 17 g | 23.8 g |
| 500 g | 85 g | 119 g |
| 1000 g | 170 g | 238 g |
Real recipes use a superfat discount (typically 5%) and almost always blend several oils. Always run your full recipe through the Soaply lye calculator rather than weighing lye from a single-oil table.
