Deodorant effects of a supercritical hops extract: antibacterial activity against Corynebacterium xerosis and Staphylococcus epidermidis and efficacy testing of a hops/zinc ricinoleate stick in humans through the sensory evaluation of axillary deodorancy

The hops extract has good in vitro antibacterial properties and, in combination with zinc ricinoleate in an appropriate base, delivers in vivo odor reduction. The clinical efficacy is likely due to a combination of the base ingredients and the antibacterial actives.
