Bactericidal Efficacy of "Antibacterial (Jokin) " Products

Abstract

Commercially available “antimicrobial (Jokin) ”products for use on environmental surfaces with claims and descriptions such as “Jokin,” “alcohol,” and “99.9%” were examined for microbicidal ef- fects on Enterococcus faecalis. We found that 13 of 28 (46.4%) products tested had no bacteri- cidal effects after 5-min contact with the microbes. Of the 14 products with ethanol (ranging from 7.9 to 65.7 vol%), 1 (7.1%) had no bactericidal effect. Of the ten products with chlorine com- pounds (ranging from 0.06 to 144 ppm), all (100%) had no bactericidal effect. We found that close to half of all products with “antibacterial (Jokin)” effects had no bactericidal effect.
