Abstract: Disclosed are oral care compositions, for example dentifrice compositions, comprising an oral care composition comprising an orally acceptable vehicle, metal oxide particles having an average particle size of no greater than a dentin tubule and at least one amino acid capable of chelating the metal oxide. The composition may comprise a polymeric adherent material for adhering the metal oxide particles in the dentin tubule. The metal oxide particles have a median particle size of 5 microns or less, and may comprise zinc oxide.

Abstract: Described herein are compositions comprising combinations of metal salts, and methods of preparing and using the same.

Abstract: Described herein are oral care compositions comprising an effective amount of aluminum chlorohydrate suspended in a carrier for preventing, reducing or inhibiting dentinal hypersensitivity, the aluminum chlorohydrate exhibiting a SEC chromatogram having a SEC Peak 4 to Peak 3 intensity ratio of at least 7 and a Peak 4 intensity greater than a Peak 5 intensity; and methods of using the same.

Abstract: Described herein are dual component oral care systems comprising a first component comprising a peroxygen compound and having a first pH and a second component comprising at least one salt of a weak mono or polyprotic acid and having a second pH wherein the second pH is higher than the first pH and is less than 10.0 wherein when combined the first and second components form a tooth-whitening composition having a pH of greater than 6.0 and less than 10.0 is provided.

Abstract: Described herein are oral care compositions comprising (i) a peroxide whitening agent, and (ii) an abrasive in the form of particles, wherein the particles are pre-coated with a coating layer composed of a coating material selected from at least one substantially saturated C12-C30 fatty acid, at least one monosaturated C12-C30 fatty acid, and at least one silicone polymer, or any mixture of two or more thereof.

Abstract: Oral care compositions comprising a crosslinked polyvinylpyrrolidone complexed with hydrogen peroxide, together with an ethylene oxide-propylene oxide block copolymer. Some embodiments further comprise a calcium abrasive, e.g. calcium pyrophosphate or calcium carbonate, and some may have less than 3% water.

Abstract: Described herein are regimens for whitening teeth, comprising administering to the teeth an effective amount of a first oral care composition comprising a bleaching agent and allowing the first oral care composition to remain on the teeth for at least 30 seconds, and brushing the teeth with a second oral care composition. Kits comprising a first oral care composition comprising a bleaching agent, wherein said first oral care composition is adapted to remain on said tooth for at least 30 seconds; a second oral care composition; and instructions for use, are also provided.
