    摘要： Oral care compositions containing agents that are effective for treating and modifying teeth and mucosal surfaces to be hydrophobic are disclosed. Hydrophobic modification of teeth and other oral cavity surfaces imparts a variety of end use benefits including prevention of caries, erosion, wear, staining, sensitivity and desquamation as well as providing shine, smoothness and positive tooth feel benefits. The compositions contain selected surface active organophosphate compounds that deposit and adhere to teeth and other oral cavity surfaces forming a hydrophobic coating having prolonged retention thereon. By forming a "hydrophobic coating" on the oral cavity surface is meant that the hydrophobic character of the surface is increased as measured, for example, by an increase of at least about 10 degrees in the water contact angle of the surface after treatment. The increased hydrophobic character of the surface is maintained for a period of at least about 5 minutes and desirably longer such as at least about 10, at least about 20 or at least about 30 minutes. The compositions may contain additional hydrophobic materials to further increase hydrophobicity of the surface and/or functionality of the coating to provide surface protection and many other benefits.

    摘要： Disclosed are oral care compositions and methods for overall cleaning, whitening and preventing, reducing or removing surface deposited stains on natural teeth and dental prosthesis, the compositions comprising in an orally acceptable carrier at least 0.1% by weight of a water-soluble or water-dispersible copolymer prepared by copolymerizing one or a mixture of vinyl pyrrolidone (VP) monomers with one or a mixture of C1-C19 alkyl carboxylic acid (AC) C2-C12 alkenyl ester monomers. Preferably, the compositions further comprise one or a mixture of other oral care agents selected from a water soluble alkali metal or ammonium tripolyphosphate in an amount at least about 0.5% by weight of the composition, an abrasive, preferably a precipitated silica abrasive, in an amount at least about 6% by weight of the composition and a bleaching agent in an amount at least about 0.1% by weight of the composition. This invention further relates to methods of cleaning, whitening and polishing natural teeth and dental prosthesis and of preventing, reducing or removing surface deposited stains from teeth by administering the present compositions.
