Abstract
The bactericidal efficacy of stable sodium hypochlorite (s-SH, AirRish) was evaluated through in vitro testing against planktonic solutions of Staphylococcus aureus and Staphylococcus epidermidis. After an exposure time of 5 minutes viable colony forming units of both species fell below the limit of detection with both 100 ppm and 200 ppm s-SH, a greater than 6 log10 reduction (p ‹ 0.001). Additionally, the antimicrobial effect of s-SH was also examined in hand sanitization applications. In a 60s hand rub, 200 ppm s-SH achieved a 96% reduction in hand CFUs, of similar effect as a typical alcohol sanitizer (p = 0.28). s-SH maintained considerable bactericidal efficacy at the tested concentrations.
