The big idea Concerns about unnecessary use of a common class of antimicrobial chemicals used in disinfectants reinforces recommendations to opt for soap and water or safer products, my colleagues and I determined in our recent critical review of the scientific literature. Quaternary ammonium compounds, or QACs, are increasingly marketed and used in homes, schools and workplaces with limited evidence for their appropriateness or safety.
