  • Publication number: 20070060900
    Abstract: A method of reducing odor from ostomy devices by using a hydrated dialkali monometal polycarboxylate 1:1 molar ratio of metal-to-complexing agent suspended in a carrier. As the ostomy device is filled with waste products, the hydrated dialkali monometal polycarboxylate 1:1 molar ratio of metal-to-complexing agent oxidizes the molecules of the waste products and neutralizes odor-causing molecules, and thereby reduces associated odors.

  • Publication number: 20060223988
    Abstract: Novel high resolution methods and precipitating reagents for isolating desired protein populations from proteinaceous materials are disclosed. Uniquely, the methods and precipitating reagents of this invention are suitable for selectively and sequentially isolating consistently in high yields desired protein populations from various proteinaceous materials based upon the physical and chemical characteristics inherent in, and/or peculiar to, the desired protein populations. In addition, desired protein populations isolated with the new and vastly improved methods and precipitating reagents of this invention are highly concentrated and substantially pure and biologically active. The precipitating reagents basically are an alkali metal salt of a polyfunctional organic acid, exemplified by tri-potassium citrate monohydrate or tri-sodium citrate dihydrate, and a buffer for adjusting pH. Sources of proteinaceous materials may include, for example, animal or vegetable fluids and extracts.

  • Patent number: 4708864
    Abstract: Novel methods and dental compositions for treating dental structures, such as teeth and subgingival structures, are disclosed. Uniquely, the dental compositions contain metal complexes which are characterized as having a unique aqueous proton induced dissociation property represented by a sigmoidally-shaped curve on a cartesian coordinate plot of the negative log of the metal ion concentration versus the negative log of the hydrogen ion concentration. This unique dissociation property enables the metal complexes to release therapeutic metal ions in the oral cavity for forming metal coordination complexes or salts within the dental structures. The formation of such complexes or salts within the dental structures is particularly effective and highly resistant to enzymatic degradation associated with microbial activity. Also, the metal ions of this invention are highly effective in inactivating the enzyme secreted by microbes in the oral cavity to further attenuate the disintegration process.

  • Patent number: 4680309
    Abstract: A method of treating inflammation or arthritis with metal complexes that can traverse skin and animal cell membranes intact and effectively deliver and release metal ions in a controlled manner upon demand at the targeted inflammatory or arthritic areas containing endogenous reacting moieties which demand the metal ions. The metal complexes have an aqueous proton induced dissociation property represented by a sigmoidally-shaped curve on a cartesian coordinate plot of the negative log of the metal ion concentration versus the negative log of hydrogen ion concentration. This dissociation property enables the metal complexes to release metal ions in a controlled manner upon demand at the targeted inflammatory or arthritic areas containing endogenous reacting moieties which demand the metal ions. The metal complexes can be effectively administered either topically or subcutaneously.

  • Patent number: 4278610
    Abstract: A method of making an organic metal salt or complex is disclosed by reacting a heavy metal hydroxide with an organic Lewis acid or salt thereof in the presence of a gaseous catalyst such as a form of CO.sub.2. The reaction may be controlled by the addition of a buffering agent. Other gaseous catalysts such as CO and SO.sub.2 or their related salts, can be employed. The method produces organic metal complexes or salts in a pure second salt-free state either in a solution or solid state.

  • Patent number: 4180473
    Abstract: A method of transporting metal ions by introducing a metal complex into a medium containing a moiety which demands the metal ion and the complex releases the ions in a controlled manner upon demand. The metal complexes have an aqueous proton induced dissociation property represented by a sigmoidally-shaped curve on a cartesian coordinate plot of the negative log of the metal ion concentration versus the negative log of hydrogen ion concentration. This dissociation property causes a controlled release of metal ion into mediums containing a reacting moiety upon demand for the metal ion. For example, metalworking emulsions of oil and water are stabilized by the addition thereto of minor amounts of a metal complex, e.g., disodium monocopper(II) citrate, which at alkaline pH metalworking conditions above about 7 to about 9 releases metal cations to the emulsions imparting stabilizing characteristics which prevent emulsion degradation by a number of factors commonly encountered in metalworking operations.

  • Patent number: 4129509
    Abstract: Stabilized metalworking fluid compositions are disclosed comprising an oil and water dispersion and, as a stabilizer therefor, a metal complex of a metal ion and a polyfunctional organic ligand. The metal complexes have an aqueous proton induced dissociation property represented by a sigmoidally-shaped curve on a cartesian coordinate plot of the negative log of the metal ion concentration versus the negative log of hydrogen ion concentration. This dissociation property causes a controlled release of metal ion into the oil and water dispersion to impart metal working stability to the dispersion. Metal working emulsions of oil and water are stabilized by the addition thereto of minor amounts of a metal complex, e.g., disodium monocopper(II) citrate, which at alkaline pH metalworking conditions above about 7 to about 9 releases metal cations to the emulsions imparting stabilizing characteristics which prevent emulsion degradation by a number of factors commonly encountered in metalworking operations.

  • Patent number: 4055655
    Abstract: Antimicrobial agents are disclosed containing as the active ingredient a metal complex of a metal ion and a polyfunctional organic ligand. The antimicrobial metal complexes are characterized by a very unexpected aqueous proton induced dissociation property which causes the controlled release of toxic metal ion at a pH compatible with microorganism growth. This dissociation property is represented by a sigmoidally shaped curve, i.e., one curved in two different directions like the letter "S," on a cartesian coordinate plot of the negative logarithm (log) of metal ion concentration versus the negative logarithm (log) of hydrogen ion concentration (or otherwise known as a pM-pH diagram). Antimicrobial metal complexes are also disclosed which are extremely effective in the controlled release of metal ion from the complex in about the normal range of physiological pH, i.e., about 10.sup.- 4 to 10.sup.-9 moles of hydrogen ion per liter.
