  • Publication number: 20110089073
    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.
