The aim of this study was to test efficacy of a newly developed foam disinfectant Hvězda S.C.H. using the standard procedures. The agent was initially intended for use as a detoxicant for the needs of the Army, Integrated Rescue System and Fire and Rescue Service of the Czech Republic and its active ingredient is hydrogen peroxide. Microbicidal efficacy of the agent was tested under the conditions required by the standards for the evaluation of bactericidal, fungicidal, sporicidal, mycobactericidal and virucidal activity of chemical disinfectants and antiseptics in health care settings, food, industrial, domestic and institutional areas and veterinary care facilities. In all of the efficacy tests used, the foam disinfectant Hvězda S.C.H. reduced density of test microorganisms under the prescribed conditions by at least eight orders of magnitude, even for much shorter exposure times (1, 5, 10 minutes) than usually prescribed by the standards. In conclusion, the foam disinfectant Hvězda S.C.H. easily met the requirements for the bactericidal, fungicidal, sporicidal, mycobactericidal and virucidal activity, with a reserve of several orders of magnitude, under the conditions prescribed by the standards for health care, community and veterinary settings.
