Goose Fat
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 goose fat. Multiply by your oil weight, then apply your superfat.
- NaOH (bar soap)
- 0.137
- KOH (liquid soap)
- 0.192
- Iodine
- 65
- INS
- 130
Fatty acid profile
These figures account for 91% of goose fat. 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 |
|---|---|
| Oleic | 54% |
| Palmitic | 21% |
| Linoleic | 10% |
| Stearic | 6% |
Soap qualities at 100%
What a bar made entirely of goose fat 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 goose fat and need a substitute. Check the lye maths again after swapping: SAP values differ even between oils that behave alike.
