Oral Care Whitening Compositions

Abstract

Described herein are whitening compositions comprised of a peroxide component, and an adhesion system, which effectively provide whitening using a remarkably low level of peroxide. Methods of making and using these compositions are also described herein.

1 . A non-aqueous oral care composition comprising:
 a peroxide component comprising a peroxide source in the amount of 0.05% to 0.15% of the total weight of the composition; and   40% to 80% of an adhesion system comprising:
 a hydrophobic component comprising a silicone adhesive, a silicone fluid and a dental surface adhesion enhancing agent selected from the group consisting of bees wax, mineral oil, a blend of mineral oil and polyethylene, petrolatum, white petrolatum, a blend of liquid paraffin and a butene/ethylene/styrene hydrogenated copolymer, a polyethylene wax, polyisobutene, a polyvinyl pyrrolidone/vinyl acetate copolymer; and a combination of two or more thereof, 
   
       wherein the composition when applied to the teeth is sufficiently viscous to form an adherent, continuous layer on a dental surface and deliver an effective amount of said peroxide source to a tooth surface. 
     
     
         2 . The composition of  claim 1  wherein the peroxide source is selected from the group consisting of hydrogen peroxide; urea peroxide, sodium percarbonate, sodium perborate; and a combination of two or more thereof. 
     
     
         3 . The composition of  claim 1 , wherein the peroxide component further comprises cross-linked polyvinylpyrrolidone, wherein the peroxide source is complexed with the cross-linked polyvinyl pyrrolidone. 
     
     
         4 . (canceled) 
     
     
         5 . The composition of  claim 1  wherein the peroxide source is hydrogen peroxide. 
     
     
         6 . The composition of  claim 1 , wherein the dental surface adhesion enhancing agent comprises an additional amount of cross-linked polyvinylpyrrolidone. 
     
     
         7 . The composition of  claim 6 , wherein the additional amount of cross-linked polyvinylpyrrolidone is not complexed with a peroxide source. 
     
     
         8 . (canceled) 
     
     
         9 . The composition of  claim 1  wherein the peroxide source is present in an amount from about 0.08% to about 0.12%, by weight of the composition. 
     
     
         10 . The composition of  claim 1 , wherein the peroxide source is present in the amount of about 0.1%, by weight of the composition. 
     
     
         11 . The composition of  claim 1 , wherein the silicone adhesive is a pressure sensitive silicone adhesive. 
     
     
         12 . The composition of  claim 11 , wherein the pressure sensitive silicone adhesive is a copolymer prepared by condensing a silicone resin with a dihydroxy polydiorganosiloxane. 
     
     
         13 . The composition of  claim 12 , wherein the dihydroxy polydiorganosiloxane is dihydroxy polydimethylsiloxane. 
     
     
         14 . The composition of  claim 1 , wherein the silicone resin is a silanol-containing silicone resin. 
     
     
         15 . (canceled) 
     
     
         16 . The composition of  claim 15 , wherein the silicone fluid comprises a siloxane polymer. 
     
     
         17 . (canceled) 
     
     
         18 . The composition of  claim 17 , wherein the organic material comprises mineral oil. 
     
     
         19 . The composition of  claim 1 , wherein the dental surface adhesion enhancing agent is present in an amount of about 15% to about 25%, by weight, of the composition. 
     
     
         20 . The composition of  claim 1 , wherein the dental surface adhesion enhancing agent is present in the amount of about 16% to about 20%, by weight, of the composition. 
     
     
         21 . The composition of  claim 1 , wherein the dental surface adhesion enhancing agent is present at a concentration of about 18%, by weight, of the composition. 
     
     
         22 . A method for whitening a tooth comprising applying a composition of  claim 1  to a tooth of a mammal. 
     
     
         23 . The method of  claim 22 , wherein the composition is applied using a pen. 
     
     
         24 . The method of  claim 22 , wherein the composition is maintained on the surface of the tooth for a plurality of minutes.
