Bactericidal efficacy of potassium peroxymonosulfate under various concentrations, organic material conditions, exposure timing and its application on various surface carriers

Four concentrations of potassium peroxymonosulfate (PPMS) were evaluated for bactericidal activities and indicated that the concentration is less than the manufacturing-recommended concentrations, must extend the exposure time for bacterial inactivation. However, even with and without of organic material contamination, did not show marked inactivation difference. In addition, all concentrations were inactivated on all carrier surfaces within 30 sec, except on rubber where inactivation occurred within 1 min. However, quaternary ammonium compounds were inactivated on stainless steel and plastic within 1 min and 30 sec, respectively, but not inactivated within 5 min on rubber surfaces. Conclusion, PPMS inactivated bacteria under optimal concentration, organic material conditions, exposure timing and on carrier surfaces which can useful as an alternative disinfectant for biosecurity enhancement.
