Study on the disinfection performance of a silver ion hydrogen peroxide hand sanitizer

Objective To study the disinfection performance and safety of a silver ion hydrogen peroxide hand sanitizer.Methods Using suspension quantitative sterilization test and animal test methods,the effect and safety of a certain silver ion hydrogen peroxide disinfectant in killing microorganisms were observed. Results The silver ion content of the silver ion disinfectant was 100 mg/L and the hydrogen peroxide content was 0. 752%( w/w). With the disinfectant stock solution acting for 0. 5 min,the killing logarithmic values of Staphylococcus aureus and Escherichia coli in suspension were both> 5. 00,that of Candida albicans in suspension was > 4. 00. It had obvious killing effect on Influenza virus,Parainfluenza virus and Newcastle disease virus. Using the stock solution of the disinfectant for wipe disinfection for 1 min,the killing logarithmic value of natural bacteria on hand > 1. 00. The LD50 of mouse acute oral toxicity test of this disinfectant was> 5 000 mg/kg body weight. The irritation index of the stock solution for intact skin of rabbits was 0,and it had no micronucleus effect on mouse bone marrow polychromatic erythrocytes. Conclusion The hand sanitizer can quickly kill bacterial propagators,fungi and viruses,and it is a non-toxic substance.
