Process of treating carpets with a composition comprising a brightener

Abstract

The present invention relates to a process of treating a carpet by applying a liquid composition onto a carpet using a manually or electrically operated spraying device wherein the composition contains a brightener.

What is claimed is:  
     
         1 . A process of treating a carpet comprising applying a liquid composition onto a carpet using a manually or electrically operated spraying device wherein said composition comprises a brightener, and said spraying device is non-pressurized.  
     
     
         2 . A process of treating a carpet according to  claim 1  wherein said composition is applied onto said carpet using an electrically operated spraying device.  
     
     
         3 . A process of treating a carpet according to  claim 1  wherein said brightener is selected from the group consisting of hydrophobic brighteners, hydrophilic brighteners, and mixtures thereof.  
     
     
         4 . A process of treating a carpet according to  claim 1  wherein said brightener comprises from 0.001 % to 10% by weight of the total composition.  
     
     
         5 . A process of treating a carpet according to  claim 1  wherein said composition further comprises a peroxygen bleach.  
     
     
         6 . A process of treating a carpet according to  claim 5  wherein said peroxygen bleach comprises from 0.01% to 20% by weight of the total composition.  
     
     
         7 . A process of treating a carpet according to  claim 5  wherein said peroxygen bleach is selected from the group consisting of: hydrogen peroxide; water soluble sources of hydrogen peroxide; organic or inorganic peracids; hydroperoxides; and diacyl peroxides; and mixtures thereof.  
     
     
         8 . A process of treating a carpet according to  claim 1  wherein said composition further comprises a volatile organic compound.  
     
     
         9 . A process of treating a carpet according to  claim 8  wherein said volatile organic compound is selected from the group consisting of: an aliphatic and/or aromatic alcohol; a glycol ethers and/or a derivative thereof; a polyol; and a mixture thereof.  
     
     
         10 . A process of treating a carpet according to  claim 1  wherein said composition further comprises an acid, a base, or a mixture thereof.  
     
     
         11 . A process of treating a carpet according to  claim 1  wherein said composition further comprises a surfactant selected from the group consisting of: a sulfosuccinate surfactant; sulfosuccinamate surfactant; sulfosuccinamide surfactant; carboxylate surfactant; sarcosinate surfactant; alkyl sulfate surfactant; alkyl sulphonate surfactant; alkyl glycerol sulfate surfactant; alkyl glycerol sulphonate surfactant; and a zwitterionic betaine surfactant; and mixtures thereof.  
     
     
         12 . A process of treating a carpet according to  claim 1  wherein said carpet treatment composition provides at least one of the following benefits: soil hiding benefits and carpet cleaning benefits.
