Personal cleaning composition

Abstract

A packaged cleaning composition comprising a surfactant, an aqueous acid component and an aqueous alkaline component, the acid and alkali components being provided in separate compartments within the package. On dispensing from the package the acid and alkali react together creating carbon dioxide gas which acts upon the surfactant to create a lather. The acid component is buffered to a pH ranging from 2 to 6.5

1 . A cleaning composition provided in a package, wherein the cleaning composition comprises at least one surfactant, a first aqueous acidic component and a second aqueous alkaline component, the first and second components being located in separate compartments within the package prior to being dispensed therefrom, whereby when the first and second components are combined together before or after dispensing, carbon dioxide gas is generated which acts on said surfactant to create a lather, characterised in that the first acidic component further comprises a buffer such that the pH of the first component is in the range from 2 to 6.5.  
     
     
         2 . A cleaning composition according to  claim 1 , wherein the pH of the first component is buffered in the range from 3 to 6.  
     
     
         3 . A cleaning composition according to  claim 2 , wherein the pH of the first component is buffered in the range from 4 to 5.  
     
     
         4 . A cleaning composition according to  claim 1 , wherein the first component comprises an alpha hydroxy acid in combination with a salt thereof.  
     
     
         5 . A cleaning composition according to  claim 4 , wherein the alpha hydroxy acid is citric acid and the salt is sodium citrate.  
     
     
         6 . A cleaning composition according to  claim 1 , wherein the acid constitutes from 1% to 20% by weight of the first component.  
     
     
         7 . A cleaning composition according to  claim 1 , wherein the second component comprises a carbonate or bicarbonate.  
     
     
         8 . A cleaning composition according to  claim 7  wherein the bicarbonate is potassium bicarbonate.  
     
     
         9 . A cleaning composition according to  claim 1 , wherein tho carbonate or bicarbonate constitutes from 1% to 25% by weight of the second component.  
     
     
         10 . A cleaning composition according to  claim 1 , the surfactant comprises any of the following either alone or in combination non-ionic, amphoteric, anionic and cationic surfactants.  
     
     
         11 . A cleaning composition according to  claim 10 , wherein the non-ionic surfactant comprises any of the following either alone or in combination alkyl polyglucoside, fatty alcohol ethoxylates, fatty acid alkanolamides and amine oxides and mixtures thereof.  
     
     
         12 . A cleaning composition according to  claim 10 , wherein suitable amphoteric surfactants include cocoamidopropyl betaine, amphoacetates and amphopriopionates.  
     
     
         13 . A cleaning composition according to  claim 1 , wherein the composition comprises any of the following additional ingredients either alone or in combination:—colourants, preservatives, antibacterial agents, skin conditioning agents, thickeners, and fragrance.  
     
     
         14 . A cleaning composition as hereinbefore described with reference to any of examples 1 to 5.
