I use beeswax at 1% in all my soaps, except salt bars. There are some portion of it that doesn't saponify, but at this percentage it really doesn't add much conditioning to the soap, in my opinion. I use it for it's ability to produce a hardening and longer lasting effect to the bar.
I've never seen it produce a sticky feeling to the soap, and no problems unmolding. But I'm also using SL in the process.
