Oral care compositions which provide enhanced flavour release, and which comprise a multilayer film and an orally acceptable carrier. The carrier contains a first flavour and the film has a centre layer containing a second flavour disposed between two outer surface layers. The first and second flavours may be identical or different. Each layer for the film may comprise a film forming polymer, e.g. hydroxypropylmethyl cellulose. The outer layers may comprise a release modulating agent, e.g. polyvinyl acetate or hydroxyethyl cellulose. The carrier may be a dentifrice or mouthwash. |
