摘要：
An oral composition is described. The oral composition can include a solvent having water and a cosolvent chosen from lower alkyl alcohols and acetone； a basic copolymer having basic acrylate monomeric units, basic methacrylate monomeric units, or a combination thereof； no less than 0.5 wt-% of an acid buffering or neutralizing agent； and optionally an active agent. The oral composition can include from about 6° to about 15° wt % of water, from about 30° to about 80° wt % of the cosolvent, and from about 25 to about 55° wt-% of the basic copolymer. The basic copolymer can be dissolved in the oral composition, the oral composition is capable of forming a film on a surface when contacted with an aqueous solution； and the wt-% of each component is based on the total weight of the composition.
