Coffee Butter for Soap Making
Coffee Butter is a hard butter dominated by oleic (40%), palmitic (30%), linoleic (15%). Its palmitic and stearic acids build a firm, long-lasting bar with a stable, creamy lather, making it a common backbone for cold process recipes.
Quick Facts
How Much Lye for Coffee Butter?
With a SAP value of 0.130, fully saponifying coffee butter takes 0.130 grams of sodium hydroxide per gram of oil (at 0% superfat):
| Oil amount | NaOH (0% superfat) | KOH (liquid soap) |
|---|---|---|
| 100 g | 13 g | 18.2 g |
| 500 g | 65 g | 91 g |
| 1000 g | 130 g | 182 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.
