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:
In one aspect, the application relates to novel aqueous oral care compositions useful for combining and delivering potassium salts and a basic amino acid in a high-water composition, for example, to naturally promote nitrate reduction from the oral microbiome, which can result in systemic increases of nitric oxide in blood plasma and can form part of an overall regimen to maintain, reduce, treat or control systemic blood pressure.
Abstract:
The application relates to novel aqueous oral care compositions useful for combining and delivering incompatible stannous fluoride or stannous chloride or stannous pyrophosphate, potassium salts, and an amino acid (e.g., a basic amino acid) in a high-water composition, for example, to provide effective caries prevention, protection against dental erosion, and relief from dental hypersensitivity. Additionally, oral care compositions described here useful in order to naturally promote nitrate reduction from the oral microbiome, which can eventually result in systemic increases of nitric oxide in blood plasma, and can form part of an overall regimen to maintain or control blood pressure. Compositions comprise stannous fluoride, stannous chloride or stannous pyrophosphate, nitric acid or a water-soluble nitrate salt such as potassium nitrate, a water-soluble alkali metal polyphosphate such as tetrasodium pyrophosphate or trisodium polyphosphate, a basic amino aid such as arginine and more than 10 wt% water.
Abstract:
Described herein are oral care compositions comprising an effective amount of an enzyme cocktail, wherein the enzyme cocktail comprises an alkaline protease and a second enzyme selected from cellulase, α-glucanase, and combinations thereof, in an orally acceptable carrier, together with methods of making and using the same.
Abstract:
This application relates to novel aqueous oral care compositions useful for combining and delivering incompatible stannous pyrophosphate and potassium salts in a high-water composition, for example, to provide effective caries prevention, protection against dental erosion, relief from dental hypersensitivity, and to treat or reduce malodor. The compositions comprise stannous pyrophosphate, nitric acid or a water-soluble nitrate salt, a water-soluble alkali metal polyphosphate and more than 10% water, by weight of the composition.
Abstract:
Disclosed herein are methods of promoting the aggregation and/or immune clearance of oral bacteria using oral care compositions comprising metal-amino acid complexes.
