Other than high coconut oil recipes where you use 15 to 20% superfat, what's the highest superfat you have ever used? I've been making a 50% coconut/pko recipe with shea, olive and castor and figured...what the heck. For my dry ole' skin, I tried upping the SF to 20% just to see what it would feel like. Well, it feels great! I did find a loss of big fluffy bubbles at the beginning, but still got the wonderful creamy bubbles as I washed. So, made a couple more batches and added a TBS of sugar ppo, and got fast fluffy bubbles galore. It makes a nice, hard bubbly bar. This was a tweak of Darwin's basic recipe which I've made for several years now, but as I got older and my skin got dryer, I found a need to keep upping the SF.
