I started making soap because my aging skin was drying out too much.
I started at 5% superfat, and a basic Bastile recipe or two and found that was as drying as the store soaps.
So, I upped super fat to 8% and started adding other oils and butters. I did find that adding a whole lot of different skin wonderful oils and butters in small amounts was too much, I mean I was adding multiples in a batch. Too many oils to measure in small amounts and annoying, but too oily a result. I found a recipe that I like for my skin now, with fewer ingredients and 8% super fat, but others may not like it.
For those with normal or oily skin, a basic Bastile may be best, no butters or special oils added. It will still have the glycerin that store bought soaps remove for other products, it will be nicer on the skin, but will not leave the skin too oily. 5% super fat may be fine for them. They will notice a better feel from store bought, yet not feel oily. Keep the ingredients simple for them, not too many, not too rich. Oh, and they make like dupes of fragrance from their favorite store brand if they are not allergic to fragrance. That might help with the appeal. Say, Irish Spring {insert any brand name for Irish Spring} is their favorite bar, might help to buy an Irish Spring Dupe FO to scent what you give them.
