Ok here's a question. In doing some research on alum based products some sources say you can use an alum block as an under arm deodorant. Aluminum compounds are the active ingredient in most deodorants...
Aluminum chloride
Aluminum zirconium tricholorohydrex glycine
Aluminum chlorohydrate
Aluminum hydroxybromide

So it makes sense that perhaps pure alum can be used effectively. Though, I assume you'd want to have a seperate block for the face...

Basic instructions are to dampen the block and apply in the fashion you would a stick deodorant. Having used alum on my face for a couple years, I would think that this could be a longer lasting replacement for standard issue you buy in stores.

Does anyone here use alum for this purpose? Call is sheer curiosity.
