Murumuru Butter for Soap Making
Murumuru Butter is a hard butter dominated by lauric (47%), myristic (26%), oleic (15%). 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 Murumuru Butter?
With a SAP value of 0.196, fully saponifying murumuru butter takes 0.196 grams of sodium hydroxide per gram of oil (at 0% superfat):
| Oil amount | NaOH (0% superfat) | KOH (liquid soap) |
|---|---|---|
| 100 g | 19.6 g | 27.4 g |
| 500 g | 98 g | 137 g |
| 1000 g | 196 g | 274 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.
