The effectiveness of chlorine dioxide gas in portable personal disinfectants to inhibit bacterial growth

Abstract

Disinfectants, especially air disinfectants, are necessary to prevent the potential spread of pathogens (bacteria and viruses) in the pandemic era and minimize the spread of pathogens. Some of the commercial disinfectant products that are often used generally contain chlorine dioxide (ClO2) gas. This study tested the effectiveness of two different commercial disinfectants, a liquid stick disinfectant and a powder disinfection card, to carry out the disinfection of pathogenic bacteria in the environment. These two disinfectants were used as a medium for releasing chlorine dioxide gas which has a much stronger bactericidal effect. In the form of liquid stick, ClO2 is more effective in the disinfection process rather than in the form of powder. The effectiveness of the liquid disinfectant in inhibiting the growth of pathogenic bacteria is influenced by the temperature and the area of the open space covered. Considering that the release from both disinfectants used is very small (0.002 ppmv/h), it takes a small area to ensure that the disinfection process runs effectively. HIGHLIGHTS The effectiveness of chlorine dioxide-based portable disinfectant products.; Disinfection of pathogenic bacteria in the environment to support the new normal era.; Pathogen bacteria were evaluated with the Gram staining procedure.; Growth of pathogenic bacteria is influenced by temperature and the disinfectant's coverage area.; Both disinfectants used very small dosages of chlorine dioxide gas referring to FDA's regulation.;
