erm... how could you do this?

I understand that Potassium Alum is potassium and aluminium. It creates a water soluble substance that you can spray onto skin and so-on for an antibacterial effect, and it seems to sit on the skin for a long time.

Could you do a similar thing with silver?

I'm new to this

Also, does anyone know how deodorants and things manage to stay on the skin for so long? I'm trying to design a treatment for some stuff, and I'd love to understand this.

Thank you!

Potassium aluminum sulfate is a double salt.  From here: http://en.wikipedia.org/wiki/Alum More widely, alums are double sulphate salts, with the formula AM(SO₄)₂·12H₂O, where A is a monovalent cation such as potassium or ammonium and M is a trivalent metal ion such as aluminium or chromium(III).  So there are 4 possible alums, and silver isn't one of them.
