Most soapers I know taste their soap to see if they get a zing. If not then all the lye is used ip and you are good. The drying out is usually all that happens during curing. I discount my water ( reduce the amount) so my soap is pretty hard when it comes out of the molds at 12 hours or less. I use beef tallow, olive oil, coconut and castor oil in my recipe. Once it is cool I can cut it. Sometimes I use aloe Vera juice as my liquid which makes it even more moisturizing.
It's not just drying out, it's still in a chemical reaction. You've got to leave it for the full cure period. As for soap feeling something like soap... it should at this point. My batter sudses up a little when I clean out my equipment. However, that glide you feel that doesn't seem to want to wash off, that's the lye, not soap. Lye is basic and bases feel "slippery".
