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

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.

Palmitic26%
Linoleic20%
Linolenic19%
Oleic10%
Stearic5%
Myristic3%

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.
