  • Patent number: 8679548
    Abstract: Described are highly concentrated liquid biocidal solutions formed in water from (a) specified bromine sources (e.g., BrCl or mixtures of BrCl and Br2) and (b) alkali metal salt of sulfamic acid and/or sulfamic acid and alkali metal base, wherein the solution contains >160,000 ppm of active bromine. Solutions of this type have been found to have greater stability than a commercially-available solution made from the same components containing 148,600 ppm of active bromine. Also described are new, water-soluble, solid state biocidal products formed by removing the water from solutions made in water from (a) and (b) irrespective of the initial concentration of active bromine. Removal of water can be accomplished by flashing or distillation at reduced pressure or preferably by spray drying. Such solid state products are typically in the form of powders or small particles, but can be compacted into larger forms preferably with the aid of one or more suitable binding agents.

  • Patent number: 8460269
    Abstract: The disclosed technology describes compositions and methods useful for providing cell based therapy. For example, one embodiment of cell based therapy involves the regeneration of injured tissue and/or promoting wound healing. Certain embodiments provide improved therapeutic compositions using microbubbles by delivering biological progenitor cells to the injured tissues. The administration of the microbubbles is directed by acoustic radiation forces that interact with embodiments of microbubbles comprising an acoustically active gas. As such, a high efficiency of progenitor cell delivery to injured tissue is realized. One advantage of this technique over targeted delivery of pharmaceutical compounds, is that the delivered progenitors cells may be derived from the patient (i.e., personalized therapy), thereby avoiding side effects, allergic reactions, and overall problems associated with refractive drug responses.

    Abstract: The invention provides a novel method of generating fabrics with outstanding antitoxic properties. The antitoxic properties are imparted to the fabric by introducing an active agent such as an antimicrobial or antiviral agent to the fabric. The active agent may be introduced into the fabric at multiple stages of the manufacturing process. For nonwoven fabrics, the active agent can be introduced during web formation and/or during post-processing steps. The fabrics produced in accordance with the present invention have widespread utility. For instance, they can be used as wound dressings, gowns, drapes, air filters, protective clothing and wipes.

  • Publication number: 20080014289
    Abstract: Vehicle and method is disclosed for treating and/or preventing skin disorders such as acne vulgaris and which exfoliates healthy skin by a topical application. The vehicle is a formulation incorporating hypohalous acid in a suitable pharmaceutical compound. The topical application comprises administering and scrubbing a therapeutically effective amount of hypohalous acid in the vehicle. The hypohalous acid may be hypochlorous acid, hypobromous acid, or hypoiodious acid. The suitable pharmaceutical vehicles include water, solutions, cleansers, lotion, cream, paper facial masks, and gels. The scrubbing action on the skin is exerted by a mechanic tool, such as hand, cloth towel, sponge, brush, and spraying device. Methods of preparing and compounding the vehicle for topical application and of its use are also set forth.

  • Patent number: 7309503
    Abstract: The invention includes convenient methods of preparing: (1) highly concentrated liquid bromine-containing biocidal solutions, (2) highly concentrated mixed halogen liquid bromine and chlorine-containing biocidal solutions, and (3) high-activity bromine-containing biocidal solids, all having excellent physical and chemical stability. One method yields solutions that have concentrations of bromine in excess of 18% as Br2 (8% as Cl2) in which the mole ratio of hydroxide ion to hydrogen ion source is at least 1.9:1. Another method employs elemental bromine in conjunction with a solid organic or inorganic halogenating agent to yield halogen solutions at concentrations greater than 22.9% as Br2 (10.2% as Cl2). This method can be performed under conditions that exceed the solubility of the active ingredient such that it crystallizes and is recovered as a hydrated or anhydrous salt in good yield.

  • Patent number: 7045153
    Abstract: Liquid and solid bromine-containing compositions are described. A liquid mixed halogen composition is also described. The highly concentrated liquid compositions and the high-activity solid compositions have excellent physical and chemical stability. The compositions are effective biocides in water treatment. Methods of preparing the compositions are also disclosed. These include combining a bromine compound in the oxidation state of ?1 with hydrogen peroxide and a complexing agent followed by the addition of an alkaline source. The methods may further include the use of a solid organic or solid inorganic halogenating agent, conducting a solid-liquid separation, and adding an alkaline source.
