摘要:
This invention relates to oral care composition, methods of use and methods of manufacture thereof including a single-tube, non-aqueous dentifrice whitening composition containing at least an enzyme and a substrate.
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 encompasses combinations of bioactive glass composition and potassium salts that are useful in conjunction with delivery agent such as, for example, toothpastes, mouthwashes, and oral gels. In certain embodiments, the compositions of the invention form a rapid and continuous reaction with body fluids (e.g., saliva) to promote the immediate and long-tem release of Ca and P ions to produce a stable crystalline layer deposited onto and into the dentin tubules for the immediate and long term reduction of dentin hypersensitivity and tooth surface remineralization.
摘要:
The invention provides a single phase whitening dentifrice that includes (i) a whitening agent selected from the group consisting of hydrogen peroxide, a bound peroxide and a solid peroxide (ii) an abrasive and (iii) a substantially anhydrous orally acceptable carrier, for example, polyethylene glycol. The bound peroxide may be hydrogen peroxide and a polymer and/or any peroxide compound and a porous cross-linked polymer, such as polymers of polyvinyl pyrrolidone, polyacrylates, a polymethacrylates, and a polyitaconates. The solid peroxide may be sodium perborate or urea peroxide. The invention also provides methods of whitening the tooth surfaces by contacting the surface with the composition.

摘要:
The invention includes an oral care composition that reduces and/or eliminates the perception of tooth sensitivity. The composition includes an adherent material and particles having an average particle size of about 8 microns or less. The particles are present in the composition in an amount of about 5% by weight. Also included within the scope of the invention are related methods, such as methods of occluding a dentin tubule.
摘要:
A tooth whitening composition for imparting a natural white appearance to dental enamel, comprising: a whitening particulate comprising hydroxyapatite and a delivery system comprising a silicone resin and a silicone adhesive. Methods of imparting whiteness to a tooth in a mammal are also provided.
摘要:
A tooth whitening system comprising a dental tray having a surface operable to confront a tooth surface, and a tooth whitening composition comprising a whitening agent and a hydrophobic polymer carrier. The tooth whitening composition is preferably substantially non-water soluble. A tooth whitening kit is also provided using a dental tray and the tooth whitening composition comprising a whitening composition and a hydrophobic polymer carrier.
摘要:
A composition for delivery of an oral care substance to a dental surface upon application of the composition thereto is a flexible film comprising the oral care substance dispersed in a film-forming effective amount of a polymeric matrix having a hydrophilic component, e.g., vinylpyrrolidone (VP), and a hydrophobic component, e.g., vinyl acetate (VA), in a weight ratio selected such that the film is substantially dissolvable in saliva in a period of time effective for delivery of the oral care substance. The polymeric matrix illustratively comprises a poly(VP/VA) copolymer having a VP/VA weight ratio of about 90:10 to about 10:90.
