The comparative inefficiency of traditional chemical disinfectants when used on a large scale for treating brewery plant appears to be due to their inability to penetrate deeply to the seats of contamination with micro‐organisms. Surface‐active agents have much enhanced penetrative power, and the kationic reagents (e.g., quaternary ammonium salts) are of particular interest since they possess additionally an intrinsic antiseptic power. Good results have been achieved with such compounds in sterilizing sampling cocks and filler valves, though relatively high concentrations and prolonged times of action are required to obtain complete sterility. Similarly effective results can be obtained more cheaply with mixtures of traditional antiseptics and surface active materials (e.g., sulphonate or a non‐ionic reagent). Analytical methods for determining the penetrative reagents in disinfectant solutions are described, these being used to control the concentrations of the reagents at effective levels.
