Abstract
Due to greater environmental awareness, domestic laundry habits are changing, and antimicrobial control by chemical methods has become an essential factor to compensate for the use of lower temperatures during washing machine cycles. Disinfectants added to laundry detergents are a preventive strategy to reduce the transmission of bacteria, fungi, and viruses in the home, correct aesthetic damage (e.g., spotting, discolouration, and staining), and control the microbial contamination that leads to malodour. In Europe, disinfectants are regulated by the EU Biocidal Products Regulation (No. 528/2012), which stipulates that antimicrobial efficacy must be evaluated according to standardized methods. Current European standards for laundry sanitization only apply to clinical settings (EN 16616: 2015) and are restricted to the main wash cycle. Therefore, there is a gap in the EU standards regarding the testing of product efficacy in household laundering. With the aim of addressing this gap, an international ring trial was organized to evaluate the robustness of a new method (prEN 17658) designed to test the efficacy of antimicrobial laundry products in a domestic setting. The seven participating laboratories were equipped with 5 different laboratory-scale devices to simulate the washing process, and they evaluated 7 microbial parameters for 2 experimental conditions and 3 levels of active substance. The analysis of data according to ISO 5725–2 and ISO 13528 demonstrated that the method was robust. All reproducibility standard deviation values were between 0.00 and 1.40 and the relative standard deviation indicates satisfactory reproducibility. Values of logarithmic reduction ranged from less than 2 log10 for tests with water to more than 5 log10 when disinfectants were added. The evidence generated by the ring trial was presented in a proposal for a standardized method under CEN/TC 216, in which the SOP used in the ring trial is referred to as the prEN 17658 phase 2 step 2 test method covering chemothermal textile disinfection in domestic settings.
