Abstract:
This invention relates to oral care compositions comprising a basic amino acid or salt thereof, a sugar alcohol, and an optional fluoride source, wherein the oral care composition is in an amount effective to inhibit a pH reduction consequent to bacterial glycolysis in the oral cavity; and to methods of using and of making these compositions.
Abstract:
Disclosed herein are oral care compositions comprising a zinc amino acid halide. Methods of making and using the compositions are also provided.
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:
A capsule slury including at least one coacervated capsule and at least 10 wt % humectant is disclosed. The humectant may be sorbitol, glycerin, polyethylene glycol, propylene glycol, xylitol, erythritol and/ or betaine.
Abstract:
Film forming compositions and methods for occluding dentin tubules of teeth to treat dentinal hypersensitivity of the teeth are provided. The film forming compositions may include a hydrophobic copolymer, a rosin, and an orally acceptable solvent. The hydrophobic copolymer may include an acrylate/octylacrylamide copolymer, such as 2-propenoic acid, 2-methyl-, 2- methylpropyl ester, polymer with 2-propenoic acid and N-(1, 1,3,3- tetramethylbutyl)-2- propenamide. Methods for treating dentinal hypersensitivity may include contacting the film forming composition with surfaces of the teeth.
Abstract:
Disclosed herein are dentifrices comprising a zinc amino acid halide, which provide a precipitate of zinc oxide upon use with dilution with water and/or saliva. Methods of making and using the dentifrices 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.
Abstract:
The present invention is directed to oral compositions comprising an orally-acceptable carrier and a silica abrasive comprising a precipitated amorphous silica compound having an average particle size of from 5 μm to 20 μm, oil absorption of from 60 cc/100 g to 120 cc/100 g, and an Einlehner hardness of from 4 to 11, and methods of use thereof
Abstract:
This application is directed to methods of assessing polymer deposition on dental surfaces using near infrared spectroscopy, providing a rapid and efficient method to screen for and identify optimal polymers for use in oral care formulations, (i) near infra red (IR) absorption of a dental substrate is measured in the absence of a polymer under test, and subsequently of the test sample comprising the dental substrate contacted with the test polymer. After washing or rinsing the test sample near IR of it is determined again (iii). The IR absorption of the test polymer itself is also measured (ii). Through the comparison of the three measurements (i), (ii), and (iii) the degree of deposition and retention of the test polymer on the test sample is determined.
