<p>An oral care composition having enhanced flavor release comprising an orally acceptable carrier containing a first flavor and a multilayer film for extended or delayed flavor release, the multilayer film including at least a center layer containing a second flavor, the center layer positioned between two outer surface layers, each surface layer including a release modulating agent, the first and second flavor being the same or different. The film is adapted to adhere to an oral cavity surface and the outer surface layers may comprise a mucoadhesive polymer, e.g. carboxy polymethylene, polycarbophil or polyvinyl pyrrolidone, and a film forming polymer, eg. hydroxypropylmethyl cellulose (HPMC). Suitable release modulating agents include HPMC and polyvinyl acetate. The carrier may be a toothpaste or mouthwash.</p> |
