Corn Oil for Soap Making
Corn Oil is a liquid liquid oil dominated by linoleic (51%), oleic (32%), palmitic (12%). Dominated by unsaturated fatty acids, it produces a gentle, skin-loving bar. Bars high in it need extra cure time or a hard oil alongside for firmness.
Quick Facts
How Much Lye for Corn Oil?
With a SAP value of 0.137, fully saponifying corn oil takes 0.137 grams of sodium hydroxide per gram of oil (at 0% superfat):
| Oil amount | NaOH (0% superfat) | KOH (liquid soap) |
|---|---|---|
| 100 g | 13.7 g | 19.2 g |
| 500 g | 68.5 g | 96 g |
| 1000 g | 137 g | 192 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.
Predicted Bar Properties
Derived from the fatty acid profile, for a bar made of 100% corn oil:
