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:
This invention relates to oral care compositions comprising a basic amino acid or salt thereof, and a small particle fraction: and to methods of using and of making these compositions.

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:
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.
摘要:
An oral composition comprising an orally acceptable vehicle for such composition, an effective therapeutic amount of an antibacterial compound comprising a halogenated diphenyl ether, an effective therapeutic amount of an anti-hypersensitivity agent comprising a potassium salt, and a solubilizing agent for the antibacterial compound, the solubilizing agent comprising, in combination, sodium lauryl sulfate and a cyclodextrin.
摘要:
Described herein are light-based devices for use in the detection of plaque or delivery of a whitening effect; and, inter alia, toothpaste formulations containing ultraviolet brighteners that provide a whitening or bleaching effect when exposed to ultraviolet radiation.
