Oral Care Compositions and Methods for the Same

Abstract

A film forming composition and methods for preventing acid erosion of teeth and preventing the formation of caries on teeth are disclosed. The film forming composition may include a hydrophobic copolymer, a fluoride compound, and an orally acceptable solvent. The film forming composition may also include a cellulose derivative, a rosin, a fluoride compound, and an orally acceptable solvent.

1 . A film forming composition for preventing the formation of caries on teeth, the film forming composition comprising:
 a hydrophobic copolymer;   a fluoride compound; and   an orally acceptable solvent,   
       wherein the hydrophobic copolymer comprises an acrylate/octylacrylamide copolymer, wherein the composition is free of any adhesives, wherein the amount of the adhesives is less than 0.01 weight % based on a total weight of the composition, and wherein the composition does not contain an alkyl cellulose ether. 
     
     
         2 . The film forming composition of  claim 1 , wherein wherein the acrylate/octylacrylamide copolymer is selected from the group consisting of 2-propenoic acid, 2-methyl-, 2-methylpropyl ester, polymer with 2-propenoic acid and N-(1,1,3,3-tetramethylbutyl)-2-propenamide. 
     
     
         3 . The film forming composition of  claim 1 , wherein the fluoride compound is a soluble salt of a fluoride ion. 
     
     
         4 . The film forming composition of  claim 3 , wherein the fluoride compound comprises one or more of sodium fluoride, potassium fluoride, calcium fluoride, zinc fluoride, zinc ammonium fluoride, lithium fluoride, ammonium fluoride, stannous fluoride, and stannous fluorozirconate, preferably, the fluoride compound comprises sodium fluoride. 
     
     
         5 . The film forming composition of  claim 1 , wherein the orally acceptable solvent comprises one or more of ethanol, methanol, isopropanol, butanol, water, acetone, methyl ethyl ketone, ethyl acetate, butyl acetate, cyclohexanone, cyclohexane, methylene chloride, chloroform, carbon tetrachloride, trichloroethylene, perchloroethylene, methyl glycol acetate, toluene, benzene, diethyl ether, and benzyl alcohol, preferably, the orally acceptable solvent comprises ethanol.
