  • Publication number: 20080145321
    Abstract: Oral care compositions comprising: (a) a peroxide complex comprising a peroxide component and an N-vinyl heterocyclic polymer (e.g., poly-N-vinyl polylactam, or poly-N-vinyl-polyimide); (b) a whitening agent (e.g., hydrogen peroxide); and (c) an orally acceptable carrier. In one embodiment, the carrier comprises a film forming material. Methods are also provided for making an oral care composition comprising: (a) mixing a whitening agent, silicone adhesive and carrier fluid to form a homogenous mixture; (b) adding a peroxide complex to said homogenous mixture, wherein said complex comprises hydrogen peroxide and an N-vinyl heterocyclic polymer; and (c) mixing under vacuum.

  • Patent number: 6126923
    Abstract: A method for forming a striped dentifrice wherein a first dentifrice which appears unstriped when stored in a container having sidewalls at least a portion of which is transparent, is transformed into a striped dentifrice upon extrusion from the container, which method comprises storing the first dentifrice in the container provided with discharge means and striping means within the discharge means, sequentially filling the container with a striping dentifrice having a color which distinguishes the striping dentifrice from the first dentifrice, the striping dentifrice being stored in an area of the container separate from the first dentifrice, followed by filling the container with the first dentifrice, applying pressure on the dentifrices to cause the striping dentifrice to be applied to the first dentifrice within the container area in which the second dentifrice is stored and be simultaneously extruded together from the container, so that upon extrusion, the extruded dentifrice appears to have been magical
