- Both antiperspirants and deodorants have an antibacterial action.
- Antiperspirants also cause less sweat to be secreted, so there is
- less of a medium for bacterial growth, the phenomenon which actually
- causes the odor.

- Well, most deodorants are simple antibacterial agents dispersed in a suitable
- medium. Speed Stick is essentially an antibacterial glycerine soap (try
- putting it on a armpit wet from the shower.) Zirconium salts were popular
- for a while as alternates to aluminum salts, but they were withdrawn from
- the market because they could cause granulomas.
