Abstract
Abstract The stability of disinfectant concentrates comprising ' peracetic or perpropionic acid, hydrogen peroxide acetic or propionic acid, water and a wetting agent is improved when an alkyl aryl sulphonic acid is employed as the wetting agent. The preferred wetting agent is dodecyl benzene sulphonic acid.
