Saw Palmetto 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 saw palmetto oil. Multiply by your oil weight, then apply your superfat.

Fatty acid profile

These figures account for 89% of saw palmetto 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.

Soap qualities at 100%

What a bar made entirely of saw palmetto 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.

What that means in a recipe

Very high in the short-chain saturated acids (cleansing 42), so it lathers readily and strips oil aggressively. Used as most of a recipe it tends to feel drying, which is why it is usually paired with softer oils rather than used alone.

Derived from the numbers above rather than written by hand, so it stays in step with the data. Tendencies, not guarantees — your oils, water, and technique all move the result.

Oils that behave similarly

Closest matches by fatty acid makeup — the usual starting point when you have run out of saw palmetto oil and need a substitute. Check the lye maths again after swapping: SAP values differ even between oils that behave alike.
