Yea, some last a while, and some basically wash down the drain. I think EO's stay on the skin a bit longer in my experience, than FO's. This is a good question that I've seen asked elsewhere many times, and like Tab said, some are better than others. I tell my customers, my soap is aroma therapy in the shower. That is what I strive for, just a great lathering, conditioning bar that takes your mind off your worries for 10 minutes. If you can do that, and leave a scent on a body for a little while, well, you've accomplished a good thing! Keep those questions coming!
