Peach Kernel Oil for Soap Making
Peach Kernel Oil is a liquid liquid oil dominated by oleic (65%), linoleic (25%), palmitic (6%). 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 Peach Kernel Oil?
With a SAP value of 0.136, fully saponifying peach kernel oil takes 0.136 grams of sodium hydroxide per gram of oil (at 0% superfat):
| Oil amount | NaOH (0% superfat) | KOH (liquid soap) |
|---|---|---|
| 100 g | 13.6 g | 19 g |
| 500 g | 68 g | 95 g |
| 1000 g | 136 g | 190 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.
