An oral care composition and method are described in which the composition includes a film or a plurality of film fragments entrained in a carrier. The film or plurality of film fragments comprises a zinc compound and the carrier comprises a polysaccharide and a maleic anhydride copolymer. The composition and methods provide benefits including one or more of increased consumer acceptability, improved solubility of zinc thus permitting the use of lower amounts of zinc compounds and reducing the adverse astringency associated with zinc, decreased adverse reactions brought about by the presence of zinc ions, enhanced aesthetics, improved stability for active or other functional materials, and controlled delivery of active materials such as zinc.
