I have always had great success with Weleda, Balmex, and my fave-Burt's Bees. I use fb's pretty much exclusively and have had no buildup issues on my fleece as well.
Not sure on all the benefits, I just know that natural is better and safer for baby. Like all of Burt's bees products are edible, though you I don't recommend snacking on them, but they are not harmful if ingested. I have a curious little guy who likes to "taste" anything it seems like and so I have no worries with having the burts bees around.
I am sure someone on this board could give you a better answer. I too would like to hear the answer as well.
