Antimicrobial Efficacy of Laundry Detergents with Regard to Time and Temperature in Domestic Washing Machines
TENSIDE SURFACTANTS DETERGENTS(2016)
摘要
In times of low -temperature washing, laundry hygiene gains importance, as microbial contaminations on textiles can cause infection transmission and malodour formation. This study systematically investigated the antimicrobial effect of laundry detergents (solid and liquid market detergents) with regard to time and temperature in domestic washing machines. To evaluate the microbial reduction, cotton swatches contaminated with Staph. aureus, Ent. hirae, Ps. aeruginosa, C albicans and T. mentagrophytes were washed at 20 to 60 degrees C, varying the washing time, with and without detergent. All tested washing factors affected the antimicrobial effect of to a varying extend, depending on the germ. The used solid market detergent containing activated oxygen bleach provided a way to achieve high microbial reductions in low temperature washing.
