Abstract

There is prepared an iodophor solution comprising PA1 (a) 0.5 to 3 weight percent iodine, PA1 (b) 10 to 30 weight percent phosphoric acid, PA1 (c) 5 to 30 weight percent acetic acid, and PA1 (d) 0.5 to 20 weight percent of a polymer Having an average molecular weight between 500 and 10,000 and consisting essentially of repeating units of the general formula ##STR1## where X in 90 to 65% of the cases is COOH, in 10 to 35% of the cases is ##STR2## and in 0 to 10% of the cases is CH.sub.2 OH and/or CN and/or ##STR3## the side chains being distributed statistically at random. The solution is made up with water to 100 weight percent. Preferably there is present hydrogen iodide, alkali metal iodide, alkaline earth metal iodide or ammonium iodide. Also there can be present a wetting agent such as sodium lauryl sulfate or sodium dodecylbenzene sulfonate or sodium dihexylsulfosuccinate.
