Title: EXPERIMENTAL OBSERVATION ON GERMICIDAL EFFICACY OF A POWDER DISINFECTANT OF SODIUM DICHLOROISO CYANURATE.
Abstract: Objective:To know the germicidal efficacy and stability of a powder disinfectant mainly containing sodium dichloroiso cyanurate.Methods:Suspension quantitative germicidal test and accelerated stability test were carried out.Results:The results showed that the killing index of Staphylococcus aureus and Escherichia coli in suspension exposed to the solution of sodium dichloroiso cyanurate containing 300 mg/L of available chorine for 15 min were higher than 5.00;After incubated at 37℃ for 3 months,the available chorine of the disinfectant decreased by 3.32%;The solution containing 300 mg/L of available chorine attained up to standard disinfection in the spot disinfection test of object surface;Observation on the germicidal efficacy of the solution containing 500 mg/L of available chorine in the dinner and drinking sets disinfection test,the exposure time required to attain up to standard disinfection was 20 min;The solution containing 6 mg/L of available chorine attained up to standard disinfection in the drinking water disinfection test.Conclusion:This disinfectant is a disinfectant with good germicidal efficacy and stability.
