Unit-Dose Oral Care Compositions

Abstract

Unit-dose oral care composition comprising a fibrous composition and/or an open cell foam with a low level of inorganic salts. Oral care compositions that dissolve quickly upon initial contact with water. Oral care compositions which leave a low amount of residue on surfaces upon use. Methods of use of unit-dose oral care compositions.

What is claimed is: 
     
         1 . A unit-dose oral care composition comprising a solid soluble foam composition, the solid soluble foam composition comprising:
 (a) surfactant;   (b) polymer;   (c) fluoride; and   (d) plasticizer,   wherein the solid soluble foam composition comprises less than about 1% of a polyphosphate.   
     
     
         2 . The unit-dose oral care composition of  claim 1 , wherein the oral care composition has a Total Dissolution Time of less than about 50 seconds. 
     
     
         3 . The unit-dose oral care composition of  claim 1 , wherein the unit-dose oral care composition has a mean void volume of at least about 75%. 
     
     
         4 . The unit-dose oral care composition of  claim 1 , wherein the unit-dose oral care composition has a surface area of from 50 mm-1 to about 150 mm-1. 
     
     
         5 . The unit-dose oral care composition of  claim 1 , wherein the polyphosphate comprises a pyrophosphate. 
     
     
         6 . The unit-dose oral care composition of  claim 1 , wherein the fluoride comprises stannous fluoride, sodium fluoride, potassium fluoride, amine fluoride, sodium monofluorophosphate, zinc fluoride, or combinations thereof. 
     
     
         7 . The unit-dose oral care composition of  claim 1 , wherein the polymer comprises polyvinyl alcohol, starch, carbomer, pullulan, pectin, corn starch, modified corn starch, hydroxypropyl methylcellulose, or combinations thereof. 
     
     
         8 . The unit-dose oral care composition of  claim 1 , wherein the plasticizer comprises polyols, polycarboxylic acids, polyesters, other suitable plasticizers, or combinations thereof. 
     
     
         9 . The unit-dose oral care composition of  claim 8 , wherein the polyol comprises ethylene glycol, glycerin, erythritol, threitol, arabitol, xylitol, ribitol, mannitol, sorbitol, galactitol, fucitol, iditol, inositol, volemitol, isomalt, maltitol, lactitol, maltomtriitol, maltotetraitol, polyglycitol, or combinations thereof. 
     
     
         10 . The unit-dose oral care composition of  claim 1 , wherein the unit-dose oral care composition comprises from about 0.01% to about 40%, by weight of the unit-dose oral care composition, of calcium. 
     
     
         11 . The unit-dose oral care composition of  claim 10 , wherein the calcium comprises calcium abrasive, calcium salt, or combinations thereof. 
     
     
         12 . The unit-dose oral care composition of  claim 1 , wherein the composition comprises from about 0.01% to about 10%, by weight of the unit-dose oral care composition, of metal. 
     
     
         13 . The unit-dose oral care composition of  claim 12 , wherein the metal comprises stannous ion source, zinc ion source, or combinations thereof. 
     
     
         14 . The unit-dose oral care composition of  claim 13 , wherein stannous ion source comprises stannous fluoride, stannous chloride, or combinations thereof. 
     
     
         15 . The unit-dose oral care composition of  claim 13 , wherein zinc ion source comprises zinc oxide, zinc phosphate, zinc citrate, zinc lactate, or combinations thereof.
