Abstract:
An antibacterial composition comprising thymol and totarol. This combination provides synergistic effect against gram negative and gram positive bacteria.
Abstract:
Described herein are dentifrice compositions comprising a zinc-containing salt and carboxypeptidase, wherein the zinc-containing salt is not sequestered.
Abstract:
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 zinc oxide. The composition and methods provide benefits including increased stability and shelf-life ensuring the delivery and bioavailability of zinc oxide.
Abstract:
The disclosure relates to methods of enhancing beneficial oral bacteria and decreasing harmful oral bacteria comprising administering oral care compositions comprising a saccharide prebiotic, e.g., selected from hemolysin, N-acetyl-D-glucosamine, α-D-lactose, D-(+)-trehalose or D-(+)-raffinose and mixtures thereof; and oral care compositions for use in such methods. The disclosure also relates to methods of using prebiotic oral care compositions, methods of screening, and methods of manufacture.
Abstract:
Methods for identifying a composition that neutralizes toxicity of a lipopolysaccharide are disclosed. The methods comprise comparing the amount of cytokine and/or prostaglandin E2 secreted by cells that have Toll-like receptors activated by a lipopolysaccharide in the presence or absence of a test composition. Methods of neutralizing toxicity of a lipopolysaccharide in an individual's oral cavity using compositions identified neutralizing toxicity of a lipopolysaccharide are also disclosed. Method of neutralizing toxicity of a lipopolysaccharide in an individual's oral cavity using oral care compositions that comprise combinations of zinc oxide and zinc citrate are also disclosed.
Abstract:
A composition comprising a solubilized magnolol analog comprising at least one magnolol analog chosen from propyl magnolol, isopropyl magnolol, butyl magnolol, and isobutyl magnolol, and dimethyl isosorbide. These solubilized analogs are useful in personal care, oral care, and home care compositions to provide anti-bacterial activity and reducing the expression of pro-inflammatory mediators.
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:
Methods of shifting biofilm composition in an individual's oral cavity are disclosed. The methods comprise applying to the individual's oral cavity an oral care composition in an amount effective to shift biofilm composition to increase the amount from healthy bacteria in biofilm relative to pathogenic bacteria in biofilm. The oral care composition comprising: zinc oxide, zinc citrate, and arginine. The shift in biofilm composition provides a balance having a greater amount of healthy bacteria in biofilm compared to pathogenic bacteria.
Abstract:
An oral biology model which comprises biofilm, oral epithelial tissue and a suspension of neutrophil-like cells in media is disclosed. The biofilm, which comprises oral bacteria, is produced by culturing oral bacteria on a solid substrate. The oral epithelial tissue may be gingival epithelial tissue to model the gingival crevice or buccal epithelial tissue to model the oral check. The suspension of neutrophil-like cells in media comprises neutrophil-like cells that are differentiated HL60 cells induced to a neutrophil-like phenotype by treatment with retinoic acid. Methods of using the oral biology model to test and compare compounds and formulations or to screen compounds and formulations for their effect on release of inflammatory signals, their effect on biofilm and oral bacteria and/or their effect on the cellular components are disclosed.
