The Efficacy of Nano-Emulsified Disinfectant in Disinfecting the Workplace Environment

Abstract

This work evaluated the quality and disinfection efficacy of nano-emulsified cresol disinfectant on common microorganisms in biosafety cabinets (BSCs). Different spraying methods (standard single spray and pulse spray) were used to investigate the effects of different doses and sealing time on the disinfection efficacy of two kinds of nano-emulsified cresol disinfectants. The results show that the nano-emulsified cresol disinfectant can kill bacteria completely when the spraying amount is more than 30 mL and the sealing time is more than 60 min. Nano-emulsified cresol disinfectant can be used for environmental disinfection in the working area of BSCs, and it is an ideal method to replace formaldehyde and chlorine dioxide in the disinfection of BSCs.
