Horse Oil
Saponification values, fatty acid makeup, and what this oil does in a bar of soap.
Saponification values
Grams of lye needed to saponify one gram of horse oil. Multiply by your oil weight, then apply your superfat.
- NaOH (bar soap)
- 0.14
- KOH (liquid soap)
- 0.196
- Iodine
- 79
- INS
- 117
Fatty acid profile
These figures account for 83% of horse oil. The remainder is made up of fatty acids this model does not track, so treat the derived qualities below as indicative rather than complete.
| Fatty acid | Percentage |
|---|---|
| Palmitic | 26% |
| Linoleic | 20% |
| Linolenic | 19% |
| Oleic | 10% |
| Stearic | 5% |
| Myristic | 3% |
Soap qualities at 100%
What a bar made entirely of horse oil would score. Almost nobody soaps a single oil at 100% — this is here so you can see what the oil contributes to a blend. The shaded band is the range most makers aim for in a finished recipe.
Oils that behave similarly
Closest matches by fatty acid makeup — the usual starting point when you have run out of horse oil and need a substitute. Check the lye maths again after swapping: SAP values differ even between oils that behave alike.
- Rabbit FatSAP 0.143 NaOH
- Coffee Bean Oil, greenSAP 0.132 NaOH
- Crisco, new w/palmSAP 0.138 NaOH
- Sea Buckthorn Oil, seedSAP 0.139 NaOH
- Cranberry Seed OilSAP 0.135 NaOH
