title: Ozonated water is inferior to propanol-based hand rubs for disinfecting hands.
abstract: Ozone is a strong oxidizing biocide that has broad-spectrum antimicrobial properties. The aim of the study was to compare the efficacy of ozone to a propanol-based hand rub for hand disinfection. Twenty subjects were enrolled in an in-vivo cross-over trial (prEN 12791). Subjects treated their hands with the reference procedure (propan-1-ol 60%) or with ozone (4 ppm). Post-wash bacterial counts were determined from one hand (immediate effect), and from the other hand that had been gloved for 3h (delayed effect). The investigation indicated that ozone is inferior to propan-1-ol 60% hand rub for hand asepsis.
