I superfat in the range of 3% and actually make very nice mild soaps. A while back I made a nice Soleseif soap with a higher superfat, and my hubby hates it. He told me he feels like he is washing with oil. My drains also hate all the extra fat so back to low superfat. I admit I trade off high lather since cutting way back on coconut oil, but my customers like it better. Since returning to my original market after a histus of about 4 months I have had my return customers comment that they are so glad I am back. They were not liking what they were buying from other sellers in the market, two commented it felt like they could not rinse off the soap well and it felt oily. So I figure it is not just me, but it does take awhile and quite a few batches of soap to get the exact balance that feels well. I would recommend taking your recipe and upping the superfat, then take the same recipe but cut down the coconut oil, adding the balance to your other oils, cut the superfat down and see how the soap feels after curing for 4-8 weeks. Soaping takes a lot of time, patience, practice and testing. What works for one may not work for someone else
