Abstract
A cleaning formulation for cleaning stubborn stains comprises an aqueous solution of (a) an alkali metal alkyl sulfate wherein the alkyl is a straight chain of from about 6 to 20 carbon atoms, (b) an alkylated diphenyl oxide sulfonic acid alkali metal salt, such as sodium dodecyl diphenyl oxide disulfonate, (c) a branched chain alkyl aryl sulfonate wherein the alkyl group contains from 8 to 18 carbon atoms or (d) mixtures thereof as a detergent with less than one weight percent of sodium hypochlorite and with an amount of an alkaline builder to maintain the pH above about 11.0.
Claims8
A liquid cleaning formulation consisting essentially of an aqueous solution of (1) from 0.5 weight percent up to its limit of aqueous solubility of a synthetic detergent selected from the group consisting of (a) a water soluble alkali metal alkyl sulfate wherein said alkyl group is a straight chain moiety containing from about 6 to 20 carbon atoms, or (b) a water soluble branched chain alkyl aryl sulfonate wherein the alkyl group contains from 8 to 18 carbon atoms, or (c) water soluble mixtures thereof, (2) not more than one weight percent of said formulation of sodium hypochlorite and (3) a sufficient amount of a water soluble alkaline builder to maintain the pH of said formulation at above about 11.0 and wherein said detergent is present in excess over the hypochlorite.
