What can I use in lieu of deodorant?

I've always used lotion when I don't have deodorant, but I suppose it would be even worse on a cut than deodorant. Really, any sort of powder would work, because they absorb liquid. That's what baby powder's for, to absorb the liquid to prevent rash. Hell, flour might even work if you think about it. So the corn starch and baking soda route sounds like it'd work.
