Fatty acid profile

Soap qualities at 100%

What a bar made entirely of rice bran oil, refined 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.

• Bubbly lather1
• Creamy lather25

What that means in a recipe

Almost no cleansing contribution (1) against high conditioning (74). Gentle on skin, but a bar built mainly on this will be slow to trace, slow to harden, and low on bubbles without something to balance it.

A high iodine value (100) points the same way: more unsaturated, softer, and quicker to go off than a saturated fat.

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 rice bran oil, refined and need a substitute. Check the lye maths again after swapping: SAP values differ even between oils that behave alike.
