Novel composition

Abstract

The invention relates to non-aqueous dentifrice compositions comprising a surfactant system. The surfactant system consists of a combination of surfactants i.e., a betaine and a taurate surfactant; or a betaine and an alkyl sulphate surfactant; or a betaine, a taurate and an alkyl sulphate surfactant.

1 . A non-aqueous dentifrice composition comprising a carrier wherein the carrier comprises a surfactant system consisting of a first surfactant which is a betaine in combination with a second surfactant which is a taurate or a C 10-20  alkyl sulphate or mixtures thereof. 
     
     
         2 . A composition according to  claim 1  wherein the betaine is cocoamidopropyl betaine. 
     
     
         3 . A composition according to  claim 1  wherein the betaine is present in an amount from 0.05 to about 4% such as from about 0.2 to about 2% by weight of the composition. 
     
     
         4 . A composition according to  claim 1  wherein the second surfactant comprises a taurate. 
     
     
         5 . A composition according to  claim 4  wherein the taurate is the sole second surfactant. 
     
     
         6 . A composition according to  claim 1  wherein the taurate is sodium methyl cocyl taurate. 
     
     
         7 . A composition according to  claim 1  wherein the taurate is present in an amount from 0.5 to 2% by weight of the composition. 
     
     
         8 . A composition according to  claim 1  wherein the second surfactant comprises a C 10-20  alkyl sulphate. 
     
     
         9 . A composition according to  claim 8  wherein the C 10-20  alkyl sulphate is the sole second surfactant. 
     
     
         10 . A composition according to  claim 1  wherein the C 10-20  alkyl sulphate is sodium lauryl sulphate. 
     
     
         11 . A composition according to  claim 1  wherein the C 10-20  alkyl sulphate is present in an amount from 0.5 to about 1.5% by weight of the composition. 
     
     
         12 . A composition according to  claim 1  wherein the second surfactant consists of a mixture of a taurate and a C 10-20  alkyl sulphate. 
     
     
         13 . A composition according to  claim 1  comprising an oral care active agent selected from a fluoride source, a desensitizing agent, an anti-calculus agent, an anti-erosion agent, an antimicrobial agent, an anti-plaque agent, a whitening agent, an oral malodour agent or a mixture of at least two thereof.
