Certain dri on body

I know the body says to only use certain dry under the arms, but I would think it would be ok to use on other areas of the body, like the back and face because it's the same thing as driclor or drysol, just without any alcohol. The certain dri is cheaper for me and it is less concentrated than driclor, which I need. So do you think it would be ok to use on other areas of the body?

Well I often use Driclor on my back and on my forehead (and I know you shouldn't), so I guess it should be okay, but be careful though.
