If Listerine can freshen your breath and kill bacteria in the mouth, why can’t it do the same to the rest of your body? It’s safe!
Deodorants and antiperspirants were still in their early stages of evolution when Listerine made today’s pitch—the first commercial underarm deodorant, Mum, had arrived on the market in 1888, with the first antiperspirant, Everdry, following fifteen years later. After you read descriptions of the composition and application of early antiperspirants, Listerine’s claims begin to make sense. Early products were wet, clammy, aqueous alcoholic solutions of aluminum chloride that were poured onto a cotton ball before being dabbed on the body, a technique that Listerine’s model appears well acquainted with. Drying was a slow, sticky process that, once you got past the skin irritations and damaged clothing, reduced one’s stink.
