Background  There is little scientific evidence to support the efficacy of natural deodorants and therefore, such products may be perceived as inefficacious. The evaluation of the in vitro antibacterial activity of a hop extract and the evaluation of the odor‐reducing capacity of a hops/zinc ricinoleate‐containing product by a sensory evaluation panel is employed to verify deodorant performance.

A supercritical hops extract shows antibacterial activity against Corynebacterium xerosis and Staphylococcus epidermidis, and a hops/zinc ricinoleate stick shows odor-reducing capacity in humans, supporting its potential as a natural deodorant.
