摘要：
A composition is provided, wherein the composition comprises a water-swellable, water-insoluble polymer or a water-soluble polymer, a blend of ahydrophilic polymer and a complementary oligomer capable of hydrogen bondingto the hydrophilic polymer. The composition also includes a second water-swellable, water-insoluble polymer that provides for a phase separating filmforming composition. Active ingredients, such as a whitening agent, may beincluded. The composition finds utility as an oral dressing, for example, atooth whitening composition that is applied to the teeth in need of whitening,and removed when the degree of whitening has been achieved. In certainembodiments, the composition is translucent. Methods for preparing and usingthe compositions are also disclosed.
