摘要:
This invention relates to oral care compositions comprising an effective amount of a basic amino acid in free or salt form, together with an antibacterial agent, and to methods of using and of making such compositions.
摘要:
A dentifrice composition having a low water phase comprising effective amounts of polyphosphate and ionic active ingredients. The composition comprises a source of metal ions, an inorganic phosphate salt having four or more phosphorus atoms and a cross-linked polyvinylpyrrolidone thickening agent in a single phase. Preferred metal ions are stannous, copper and zinc, in particular from zinc citrate and stannous fluoride.
摘要:
The invention includes methods of cleaning an oral surface, maintaining oral health and/or increasing oral health. Such methods encompass contacting an oral surface with a primary oral care composition at least once daily, contacting the oral surface with a periodic oral care maintenance composition at least once monthly, wherein the periodic oral care maintenance composition comprises a basic amino acid, in free or salt form and optionally contacting the oral surface with a periodic oral care cleaning composition at least once monthly. The periodic oral care cleaning compositions suitable for use in the method comprise an abrasive system.
摘要:
A dual phase whitening oral care composition comprising a first phase comprising a bound peroxide in a substantially anhydrous carrier and a second phase comprising an abrasive and a tartar control system in an orally acceptably carrier. Methods of whitening a tooth surface are also provided.
摘要:
In various embodiments, the present invention provides a tooth whitening composition comprising a peroxide composite and an orally acceptable carrier. The peroxide composite comprises a peroxide compound and a porous cross-linked polymer, preferably in the form of a microporous particulate. The peroxide compound can be sorbed onto the porous crosslinked polymer. The porous cross-linked polymer may comprise a polymerized polyunsaturated monomer selected from polyacrylates, polymethacrylates, polyitaconates, and mixtures thereof. The carrier can be non-aqueous, and can comprise a film forming material. Methods are also provided for whitening a tooth surface with the tooth whitening compositions.
摘要:
An oral care composition and method are described in which the composition includes a film or a plurality of film fragments entrained in a carrier. The film or plurality of film fragments comprises a zinc compound and the carrier comprises a polysaccharide and a maleic anhydride copolymer. The composition and methods provide benefits including one or more of increased consumer acceptability, improved solubility of zinc thus permitting the use of lower amounts of zinc compounds and reducing the adverse astringency associated with zinc, decreased adverse reactions brought about by the presence of zinc ions, enhanced aesthetics, improved stability for active or other functional materials, and controlled delivery of active materials such as zinc.
摘要:
Described herein are preservative systems which prevent the growth of microorganisms in silica based dentifrices, compositions comprising the same; and methods of making and using the same.
摘要:
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.
