EvaClean, the infection prevention division of EarthSafe Chemical Alternatives, says the efficacy of its PurTabs disinfectant has been confirmed in a study at New York University Langone Health (NYUL).

This is one of the USA's top hospitals and its chief epidemiologist decided to conduct a study to determine the efficacy of sporicidal disinfectants for controlling Clostridioides difficile (C. diff) and Candida aruis (C. auris).

A primary goal of NYUL's study was to assess the adequacy of surface disinfection in reducing contamination. Three sporicidal chemical disinfectants were selected with minimal toxicity and surface damage profiles to determine efficacy for routine use in the healthcare setting: electrolyzed water (EW), peracetic acid/hydrogen peroxide (PAA/H2O2), and sodium dichloroisocyanurate (NaDCC), EvaClean's PurTabs disinfectant.

After phase one of the study revealed NaDCC to be the most effective chemical, phase two compared application using a two-step process of microfibre cloths followed by electrostatic sprayer on all patient room surfaces versus cloth alone. In the paper, it states electrostatic sprayers allow for touchless disinfection and could be more effective at targeting sites that are difficult to reach with the standard mop plus wipe method as it distributes positively charged particles uniformly over surfaces.

The results of the study proved NaDCC was the best sporicidal disinfectant, says EvaClean, as it produced significantly lower colony counts compared to PAA/H2O2 and EW. When compared to mopping/wiping, application with the electrostatic sprayer produced even greater results leading to the conclusion that NaDCC applied with standard microfibre cloth and mop plus an electrostatic sprayer was the most effective chemical disinfectant method.

A follow-up peer-reviewed paper discussing the clinical results is set to be published in early 2023.
