Where these proportions come from
The clearest case in the craft of superfat changing what a soap IS rather than how it feels.
Craft convention: a 100 % coconut bar needs a superfat around 20 % to be usable on skin, and is a laundry bar below about 5 %.
A canonical formulation: the proportions the craft has settled on for this kind of soap. Not transcribed from a document, and not copied from anywhere.
