    摘要: Oral care compositions comprising: (a) a peroxide complex comprising hydrogen peroxide and an N-vinyl heterocyclic polymer (e.g., poly-N-vinyl polylactam, or poly-N-vinyl-polyimide); (b) a whitening agent (e.g., hydrogen peroxide); and (c) an orally acceptable carrier. In one embodiment, the carrier comprises a film forming material. Methods are also provided for making an oral care composition comprising: (a) mixing a whitening agent, silicone adhesive and carrier fluid to form a homogenous mixture; (b) adding a peroxide complex to said homogenous mixture, wherein said complex comprises hydrogen peroxide and an N-vinyl heterocyclic polymer; and (c) mixing under vacuum.

    摘要: A composition for delivery of an oral care substance to a dental surface upon application of the composition thereto is a flexible film comprising the oral care substance dispersed in a film-forming effective amount of a polymeric matrix having a hydrophilic component, e.g ., vinylpyrrolidone (VP), and a hydrophobic component, e.g ., vinyl acetate (VA), in a weight ratio selected such that the film is substantially dissolvable in saliva in a period of time effective for delivery of the oral care substance. The polymeric matrix illustratively comprises a poly(VP/VA) copolymer having a VP/VA weight ratio of about 90:10 to about 10:90.
