    Abstract: 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.

    Abstract: Denture adhesive compositions having good hold and improved taste containing a salt of a copolymer of alkyl vinyl ether-maleic acid or anhydride. Compositions containing from about 25% to about 45%, by weight of the composition, of a salt of a copolymer of alkyl vinyl ether-maleic acid or anhydride containing a cationic salt function containing: i) from about 60% to about 72% cations selected from calcium, strontium, magnesium, or combinations thereof; ii) from 0% to about 10% sodium cations; iii) less than 1% zinc cations; and iv) from about 25% to about 40% of a free acid component; and further containing from about 15% to about 25%, by weight of the composition of a carboxymethyl cellulose having a molecular weight of from about 200,000 to about 1,000,000 daltons; and a carrier. Methods of improving the adhesion of dentures to the oral cavity by applying such compositions to dentures, the oral cavity, or both, and thereafter securing the denture to the ridge or palate of the oral cavity.
