    摘要: The present invention relates to abradable films useful, e.g., in dentifrice formulations, wherein the film is stable in formulation, but abrades to release pigment or oral care active components upon brushing. The invention provides, e.g., an orally acceptable, water insoluble film which does not dissolve under formulation conditions but disintegrates upon brushing, comprising a polymer matrix, plasticizer (e.g., propylene glycol), releasable material (e.g., color or pigment) incorporated therein; and (optionally) nonionic surfactant (e.g. polysorbate), wherein the polymer matrix comprises at least 50%, e.g., at least 75%, of poly(vinyl alcohol), and 50% or less, e.g. 25% or less, of a water-soluble cellulose ether, for example hydroxypropyl methyl cellulose; together with dentifrice comprising such films, and methods of making and using the same.
