Peroxygen Containing Cleaning Substrates with Improved Storage Stability

Abstract

Peroxygen containing cleaning substrates, such as wipes and sponges which exhibit improved storage stability, and in preferred embodiments, also exhibit an antimicrobial benefit to hard surfaces treated with the peroxygen containing cleaning substrates.

1 . A peroxygen compound containing cleaning substrates which exhibits good storage stability, and optionally but preferably also exhibits an anti-pathogentic benefit to hard surfaces which are treated with the said peroxygen compound containing cleaning substrates, which cleaning substrates comprise:
 a cleaning substrate pretreated with a finishing composition which comprises at least one diamidoamine quaternary ammonium compound, and impregnated in the cleaning substrate;   a largely aqueous composition which includes up to 5% wt. of a peroxygen compound, and which optionally further includes an acid, a surfactant, an organic solvent or further optional constituent.   
     
     
         2 . The cleaning substrate according to  claim 1  wherein the peroxygen compound is a compound containing a dioxygen (O—O) bond. 
     
     
         3 . The cleaning substrate according to  claim 1  wherein the peroxygen compound is selected from peracids, peracid salts, and peroxides. 
     
     
         4 . The cleaning substrate according to  claim 3 , wherein the peroxygen compound comprises, but preferably consists of, hydrogen peroxide. 
     
     
         5 . The cleaning substrate according to  claim 1 , wherein the largely aqueous composition comprises one or more C 1 -C 4  monohydric alcohols. 
     
     
         6 . The cleaning substrate according to  claim 1 , wherein the diamidoamine quaternary ammonium compound is selected from methyl-bis(tallow amidoethyl)-2-hydroxyethyl ammonium methyl sulfate, methyl bis(oleylamidoethyl)-2-hydroxyethyl ammonium methyl sulfate, and methyl bis(hydr.tallowamidoethyl)-2-hydroxyethyl ammonium methyl sulfate. 
     
     
         7 . The cleaning substrate according to  claim 1 , wherein the cleaning substrate comprises one or more aqueous insoluble polymer fibers, preferably wherein the polymer used to form the fibers are based on polyolefin or polyester polymers. 
     
     
         8 . A method for the treatment of hard surfaces which comprises the step of:
 applying a cleaning substrate according to  claim 1 , onto a hard surface wherein the largely aqueous treatment composition contacts the hard surface and provides a cleaning benefit, and optionally but preferably, also provides an anti-pathogenic or antimicrobial benefit thereto.   
     
     
         9 . A method for improving the storage stability of a cleaning substrate containing a largely aqueous composition which includes a peroxygen compound, the method comprising the steps of:
 pretreating the cleaning substrate with at least one diamidoamine quaternary ammonium compound, prior to applying the largely aqueous composition which includes a peroxygen compound to the cleaning substrate.   
     
     
         10 . A cleaning substrate comprising at least one diamidoamine quaternary ammonium compound, and a largely aqueous composition which includes a peroxygen compound in an amount of up to 5% wt., and which further optionally includes an acid, a surfactant, an organic solvent or further constituent.
