Ucuuba Butter for Soap Making
Ucuuba Butter is a hard butter dominated by oleic (44%), stearic (31%), linoleic (5%). Its mixed fatty-acid profile contributes a bit of everything, so it works flexibly in mid-size proportions across many recipe styles.
Quick Facts
How Much Lye for Ucuuba Butter?
With a SAP value of 0.146, fully saponifying ucuuba butter takes 0.146 grams of sodium hydroxide per gram of oil (at 0% superfat):
| Oil amount | NaOH (0% superfat) | KOH (liquid soap) |
|---|---|---|
| 100 g | 14.6 g | 20.4 g |
| 500 g | 73 g | 102 g |
| 1000 g | 146 g | 204 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.
