Oral care compositions

Abstract

The present invention relates to oral care compositions with improved flavor release characteristics and improved taste, and methods of using the same.

1 . An oral care composition comprising:
 a whitening agent, wherein the whitening agent is bound;   an anionic surfactant present in an amount from 1.75% to 2.0% w/w; and   an orally acceptable carrier having a total concentration of water of 0% to 4% w/w and wherein the water content of the oral care composition is less than 4% w/w.   
     
     
         2 . The composition of  claim 1 , wherein the anionic surfactant is selected from the group consisting of sodium lauryl sulfate and sodium lauryl sulfoacetate. 
     
     
         3 . The composition of  claim 1 , wherein the whitening agent is a bound peroxide. 
     
     
         4 . The composition of  claim 3 , wherein the bound peroxide compound is selected from the group consisting of hydrogen peroxide, peroxides of alkali and alkaline earth metals, organic peroxy compounds, peroxy acids, pharmaceutically acceptable salts thereof and mixtures thereof. 
     
     
         5 . The composition of  claim 4 , wherein the bound peroxide is hydrogen peroxide and is present in an amount from 0.1% to 2% w/w. 
     
     
         6 . The composition of  claim 5 , wherein the bound peroxide is hydrogen peroxide and is present in an amount from 1% to 2% w/w. 
     
     
         7 . The composition of  claim 3 , wherein the bound peroxide includes a peroxide compound and a cross-linked polymer. 
     
     
         8 . The composition of  claim 7 , wherein the cross-linked polymer is selected from the group consisting of polyvinyl pyrrolidone, polyacrylate, a polymethacrylate and polyitaconates. 
     
     
         9 . The composition of  claim 1 , wherein the whitening agent is present in an amount from 0.1% to 30% w/w. 
     
     
         10 . The composition of  claim 1 , wherein the anionic surfactant is present in an amount from 1.8% to 2% w/w. 
     
     
         11 . The composition of  claim 1 , wherein the anionic surfactant is present in the amount of 2% w/w. 
     
     
         12 . The composition of  claim 1 , wherein the water content of the orally acceptable carrier is from 0% to 2% w/w. 
     
     
         13 . The composition of  claim 1 , wherein the water content of the orally acceptable carrier is from 0% to 1% w/w. 
     
     
         14 . The composition of  claim 1 , wherein the water content of the orally acceptable carrier is less than 0.1% w/w. 
     
     
         15 . The composition of  claim 1 , wherein the orally acceptable carrier is selected from the group consisting of polymers and copolymers of polyethylene glycol, ethylene oxide and propylene oxide. 
     
     
         16 . The composition of  claim 1 , wherein the carrier further comprises fumed silica, an abrasive, a poloxamer and a flavoring agent. 
     
     
         17 . The composition of  claim 1 , further comprising a fluoride salt. 
     
     
         18 . The composition of  claim 1 , further comprising an active agent selected from the group consisting of an antimicrobial agent, an anti-inflammatory agent, a zinc salt and triclosan. 
     
     
         19 . The composition of  claim 1 , wherein the composition comprises a single phase. 
     
     
         20 . A method of improving patient compliance with an oral care composition, comprising applying to an oral surface an effective amount of the oral care composition of  claim 1 . 
     
     
         21 . A method of whitening a tooth surface, the method comprising contacting the tooth surface with a composition of  claim 1 . 
     
     
         22 . An oral care composition according to  claim 1  for use in a method of improving patient compliance with an oral care composition, said method comprising applying to an oral surface an effective amount of the oral care composition. 
     
     
         23 . An oral care composition according to  claim 1  for use in a method of whitening a tooth surface, said method comprising contacting the tooth surface with the oral care composition.
