Abstract
An enhanced activity aqueous disinfecting solution having a pH of from about 0.5 to about 6 and consisting essentially of (i) hydrogen peroxide in a concentration of from about 0.05 to about 8 w/w % of the solution; (ii) at least one anionic surfactant selected from the group consisting of C8 to C16 alkyl aryl sulfonic acids and alkali metal, ammonium, ethanolamine, calcium and magnesium salts thereof, sulfonated C12 to C22 carboxylic acids and alkali metal, ammonium, calcium and magnesium salts thereof, C6 to C22 alkyl diphenyl oxide sulfonic acids and alkali metal, ammonium, ethanolamine, calcium and magnesium salts thereof, naphthalene sulfonic acids and alkali metal, ammonium, calcium and magnesium salts thereof, C8 to C22 alkyl sulfonic acids and alkali metal, ammonium, calcium and magnesium salts thereof, alkali metal, ammonium, calcium and magnesium C8 to C18 alkyl sulfates, alkyl or alkenyl esters or diesters of sulfosuccinic acid in which the alkyl or alkenyl groups independently contain from six to eighteen carbon atoms and alkali metal, ammonium, calcium and magnesium salts thereof, and mixtures thereof, in a concentration range of from about 0.02 to about 8 w/w % of the solution. Optionally, the solution may contain (iii) at least one additional ingredient chosen from a monocarboxylic acid, a polycarboxylic acid, and mixtures thereof, in a concentration of from about 0.05 to about 4 w/w % of the solution; and (iv) at least one further additional ingredient chosen from benzyl alcohol, an alcohol comprising one to six carbon atoms, and mixtures thereof, in a concentration of from about 0.1 to about 10 w/w % of the solution.
