Wheat Germ Oil for Soap Making
Wheat Germ Oil is a liquid specialty oil dominated by linoleic (58%), palmitic (17%), oleic (17%). Usually added in smaller proportions for its label appeal and skin-feel contribution rather than as a recipe base.
Quick Facts
How Much Lye for Wheat Germ Oil?
With a SAP value of 0.131, fully saponifying wheat germ oil takes 0.131 grams of sodium hydroxide per gram of oil (at 0% superfat):
| Oil amount | NaOH (0% superfat) | KOH (liquid soap) |
|---|---|---|
| 100 g | 13.1 g | 18.3 g |
| 500 g | 65.5 g | 91.5 g |
| 1000 g | 131 g | 183 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.
