    摘要: Oral care compositions comprising: a) an oral care active; and b) an acrylic film forming polymer. In various embodiments, such polymers comprise monomeric units such as acrylic acid, methacrylic acid, acrylates, and combinations thereof. In one embodiment, the film forming polymer comprises a copolymer of a first monomeric unit selected from the group consisting of acrylic acid, methacrylic acid, and combinations thereof, with a second monomeric unit selected from the group consisting of acrylates, acrylamindes, acetates, and combinations thereof. In various embodiments, the polymer is a terpolymer comprising a combination of the second monomeric units. Preferably, the composition additionally comprises a lower alcohol, such as ethanol. In various embodiments, the oral care active comprises a whitening material, such as a peroxide.

    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.
