  • Publication number: 20130095159
    Abstract: 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.

  • Patent number: 8337818
    Abstract: A post foaming oral care mousse is provided by the invention. The mousse includes at least a dentifrice composition and a compressed liquid propellant having a boiling point less than ?10° C. The liquid propellant is blended into the mousse as an emulsion, and the emulsion is adapted to be dispensed from a container as a gel that foams after a time delay. The mousse has a viscosity of less than 30,000 centipoise when measured prior to the addition of the propellant. Preferably, the mousse expands at least 100 vol % in less than 5 seconds upon exposure to atmospheric pressure.

  • Publication number: 20050163729
    Abstract: A peroxide-containing dual component tooth-whitening system providing enhanced whitening efficacy, minimal gingival irritation, and tooth sensitivity is described. The system is comprised of a first component containing a peroxide compound and a peroxide-compatible abrasive and a second component containing an alkaline compound. When the components are combined and contact the surface of a tooth an enhanced whitening effect is obtained with minimal tooth sensitivity and gum irritation. A desensitizer compound, a color indicator, and a stabilizing carrier can be included in the system. In certain embodiments, the composition is substantially free of chelating agents.
