Abstract: A delivery system for delivering a enamel regeneration system to the surfaces of teeth the delivery system comprising a delivery device and a separate activator composition, the delivery device comprising; a strip of an orally acceptable flexible material, having a strip surface capable of being applied to a tooth surface, the strip having components of an enamel regeneration system deposited upon the strip surface thereof, and/or impregnated into its structure and the activator system comprising water.

Abstract: An oral care kit comprising: i) an application device ii) first non-aqueous composition comprising a whitening component and a water insoluble and/or slightly soluble calcium source; and (iii) a second composition comprising a phosphate source in which the second composition is stored separately from the first composition prior to usage of the product; and in which the first and second compositions are adapted to be applied sequentially to the application device, the device then being placed on the surface 15 of the teeth for sustained contact.

Abstract: A delivery device for delivering a enamel regeneration system to the surfaces of teeth, the 5 delivery device comprising; a strip of an orally acceptable flexible material, having a strip surface capable of being applied to a tooth surface, the strip having the enamel regeneration system deposited upon the strip surface thereof, and/or impregnated into its structure.

Abstract: The invention provides a non-aqueous oral care composition with a liquid continuous phase comprising a thickening agent, a humectant, and one or more liquid polyethylene glycols having a melting point below 25° C., in which the liquid continuous phase is structured with crystals of one or more solid polyethylene glycols having a melting point of 25° C. or above. The rheological behavior of the composition of the invention corresponds well with the characteristic rheological behavior of typical aqueous dentifrice formulations.

Abstract: The invention provides a non-aqueous oral care composition suitable for cleaning the surfaces of the oral cavity, the composition comprising: (a) from 20 to 90 wt % (by weight by based on the total weight of the composition) of one or more organic polyols having 3 or more hydroxyl groups in the molecule; (b) from 3 to 75 wt % (by weight based on the total weight of the oral care composition) of one or more particulate abrasive cleaning agents; (c) from 0.2 to 5 wt % (by weight based on the total weight of the oral care composition) of one or more surfactants, and (d) from 0.01 to 5 wt % (by weight based on the total weight of the oral care composition) of xanthan gum. The composition is easy to manufacture without the need for careful temperature control. It is also un expectedly stable and cost-effective, with suitable viscosity characteristics despite its non-aqueous nature.

Abstract: An oral care composition comprising from 0.01 to 50% by weight of the composition of a capsule, the capsule comprising a core and a coating for the core, the coating comprising a wax having a melting point of at least 70 degrees C., an oil and an opacifier and the core comprising an oil, a pigment and a shear-thinning structurant.

Abstract: A toothpaste which comprises first and second compositions, the first and second compositions comprising water, humectant and thickener and the second composition disposed coaxially within the first composition, the first composition being a gel and the second composition being opaque, the second composition comprising an opacifier at y % by weight of the second composition and the first composition comprising 0.2 to 2.0y % by weight of the first composition more thickener than is present as a weight percent of the second composition.

Abstract: Multiphase toothpaste composition comprising a first phase disposed co-axially within a second phase, each of the phases having a viscosity of from 180 000 to 250 000 mPa·s.
