The Role of Laundry Detergents in the Elements of Skin Pathogen

Background: The Corona pandemic fuelled up skin pathogen challenges in young and adults, the antimicrobial efficacy of laundry detergents could be considered particularly. However, no available data focusing on the form of laundry detergent, additives and conditions affect the antimicrobial efficacy. This study simulated washing procedures to investigate the antibacterial and antifungal activity of laundry detergents.Methods and Results: Mimic laundry procedures were performed to treat Gram-positive bacteria, Gram-negative bacteria and fungus, colony counting and propidium iodide staining were used to assess the antimicrobial activity. Powder detergent A, NaBO3*4H2O with the tetraacetylethylenediamine, 2Na2co3.3H2O with tetraacetylethylenediamine could achieve a > 5-log10 reduction of three microbial colony generation. Anionic surfactant sodium dodecylbenzene sulphonate (SDBS) group had the strongest fluorescence intensity in three microbial propidium iodide staining.Conclusions: Powder form laundry detergents are superior to liquid form, peroxide-based bleaches and bleach activator in solid form, the solid surfactants with matched PH and alkyl chain length showed a considerable antimicrobial effect.
