This is what is known otherwise as an alum stone typically used post shaving at barbershops to heal cuts and nicks after shaving, it just so happens to work as an anti-antiperspirant, I like this because its virtually odourless, so if you use an expensive aftershave or perfume its not going to mix with it, it also is a roll on so no sprays going into the atmosphere.
