Exactly this!I used lanolin in my last batch of shave soap (thanks to the good examples set by Lee Bussey and The Gent) at 5% of the total oils. I can feel a faint, pleasant coating of lanolin on my skin after I build up a lather with my hands and then rinse it off. This is distinctly different than my previous shave soaps w/o lanolin. I like the skin conditioning the lanolin provides. It might add some slickness and density to the lather, but that's just my very informal opinion. I don't think I'd want to add more than 5% however. I agree w lsg -- a little lanolin goes a long ways.
