Soap qualities at 100%
What a bar made entirely of yangu oil (cape chestnut) 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
Almost no cleansing contribution (0) against high conditioning (76). 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.
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.
