Abstract:
Improved analytical, diagnostic, monitoring, and other methods (and their associated devices) for evaluating the extent of deposition of an agent onto a substrate are described. Exemplary methods may be used in the in the monitoring of the dental health of patients or in the fast, efficient screening and/ or characterization of formulations in terms of their use for depositing oral actives onto tooth surfaces. The methods involve the direct or in situ analysis of substrates, onto which agents are deposited, using Near-IR spectroscopy and/ or UV spectroscopy.
Abstract:
This invention relates to oral care compositions comprising a basic amino acid or salt thereof, and a small particle fraction: and to methods of using and of making these compositions.
Abstract:
An oral care composition having a soluble zinc polyphosphate complex made by combining ingredients including a zinc salt, a plurality of long chain polyphosphates having 6 or more phosphate polymer units, and a solvent, the relative amount of organic zinc salt and long chain polyphosphates provides a phosphorus to zinc mole ratio of at least 6:1. Further provided is a method of treating a subject suffering from dentinal sensitivity applying the oral care composition to the teeth and gums of the subject.
Abstract:
Disclosed herein are methods of enhancing the solubility and delivery of one or more active ingredients found in magnolia extract, or a synthetic analog thereof, in an oral composition.
Abstract:
This invention relates to oral care compositions comprising an effective amount of a salt of a basic amino acid, the salt having a pH in an unbuffered solution of less than about 7.5; an effective amount of a soluble fluoride salt; and a particulate material which has a pH in an unbuffered solution of less than about 7.5; and to methods of using and of making such compositions.
Abstract:
A soluble zinc polyphosphate complex made by combining ingredients which include an inorganic zinc salt and a plurality of long chain polyphosphates having 6 or more phosphate polymer units, the relative amount of inorganic zinc salt and long chain polyphosphates providing a phosphorus to zinc mole ratio of at least 6:1. Further provided is a method of making this soluble zinc polyphosphate.
