Abstract:
An oral care composition comprises arginine or lysine, zinc citrate and zinc oxide, a fluoride source, and glycerin, as well as to methods of using and of making the composition.
Abstract:
Provided herein is a method for determining the bioavailability of a metal ion in a composition comprising a source of the metal ion, wherein the metal ion has antimicrobial activity, and wherein the method comprises: a) incubating a sample of the composition with bacterial cells, and b) determining the viability of the bacterial cells after incubation. The method is useful for determining the effect of agents on the bioavailability of metal ions in a composition.
Abstract:
Described herein are oral care compositions comprising a combination of zinc oxide and zinc citrate, and methods of preparing and using the same.
Abstract:
This application provides, among other things, oral care compositions where the addition of a stabilizing amount of a nonionic gelling and thickening agent, (e.g., hydroxyethyl cellulose (HEC)), to formulations comprising a bisbiguanidine (e.g., chlorhexidine (CHX)) agent allows for proper structure and consistency to the formulation and to allow it to be used as a gel or a toothpaste to facility delivery of chlorhexidine, among other actives, to the teeth or gums.
Abstract:
An oral care composition comprises (a) arginine or lysine; (b) zinc citrate and zinc oxide; (c) fluoride source; and (d) a silica abrasive which exhibits an acid pH when measured as an aqueous slurry. The composition is used in the manufacture of a product for application to the oral cavity of a subject in need thereof to improve oral health.
Abstract:
Described herein are films comprising a zinc-containing compound and a film-stabilizing ingredient, for use in oral and personal care compositions.
Abstract:
Methods of increasing sIgA levels in an individual's oral cavity are disclosed. The methods comprise applying effective amounts of zinc oxide, zinc citrate, and arginine. Methods of increasing the concentration of sIgA in the individual's mucosa pellicle in the oral cavity are disclosed. Methods of increasing phagocytotic activity of phagocytotic cells in the individual's oral cavity are also disclosed. In addition, methods of increasing levels of β-Defensin 1 in the individual's oral cavity are disclosed.
Abstract:
The present invention relates to oral hydrogel compositions, more particularly to thermosensitive gel compositions, which undergo a sol-gel transition in the oral cavity, and which optionally comprise therapeutic actives for sustained release.
Abstract:
Described herein are oral care compositions comprising an amino acid; a combination of zinc ion sources; and a thickening system comprising a nonionic cellulose ether having a molecular weight of from about 300,000 to about 350,000; and a polysaccharide gum; along with methods of making and using same.
