Abstract:
The present invention relates to an oral composition and method for alleviati the symptoms associated with xerostomia using encapsulated cation-releasing compounds formulated either intimately together or in separate compartments in a composition containing cation-sensitive mucoadhesive polymers.
Abstract:
A quaternary ammonium salt encapsulated by a polymeric microcapsule an methods for manufacturing such microcapsules are described. The quaternary ammonium salt can be cetylpyridinium chloride. The polymeric microcapsule encapsulating the quaternary ammonium salt can be used as an ingredient in a dentifrice.
Abstract:
Disclosed are anti-erosion oral care formulations and methods that provide erosion protection while maintaining adequate cleaning performance. The anti-erosion oral care formulations include a copolymer of a methylvinyl ether and a maleic anhydride and a metal compound or salt that becomes more soluble at acidic pH.
Abstract:
Disclosed herein are oral care compositions comprising a zinc amino acid halide. Methods of making and using the compositions are also provided.
Abstract:
The invention provides mouthwash formulations having improved taste, coupled with good whitening efficacy, which comprise a whitening agent such as hydrogen peroxide together with a combination of a first acid such as citric acid and a second acid such as phosphoric acid. In further embodiments, the mouthwashes may comprise a sucralose and saccharin combination, an acidic polymer, one or more anticalculus agents, e.g., alkali pyrophosphate salts, copolymers of maleic anhydride and methyl vinyl ether and other ingredients.
