While I have not tried this personally, I was told by a friend that she very successfully makes the above ingredients into a paste and applies to her armpits, then wipes away residue when dry.

I'm convinced that a lot of the body odor we experience comes from the residue of shampoo, conditioner, soap, and other chemicals left on our skin. (70% of the oxygen we comes in comes through the skin and not the lungs. ) By switching to natural alternatives (borax and baking soda), after a year, I could wear the same socks for four or five days and no one would know it. If I'm right, I've uncovered a pretty sly business model--more soap, more body odor, more deodorants, more soap and even more body odor. In the past, it was common to wash your hair once a month. I'm convinced people didn't walk around smelling like they were living on the street.Replied By Rf (Jc, Nj) on 02/22/2011
I just started using nothing but coconut oil as a deodorant. I'm loving it. I've used many kinds of deodorants including the sodium stone, and so far this is the best for keeping odor under control
