Patents by Inventor Susan Leander

Susan Leander has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9873751
    Abstract: This invention pertains to a polymeric composition and an antimicrobial composition, each comprising a superabsorbent polymer (SAP), such as used in diapers and sanitary napkins, and peroxide. The superabsorbent material can be made by the process of treating a preformed SAP, such as a crosslinked polyacrylate salt, with a treatment solution comprising hydrogen peroxide dissolved in water, followed by drying. The resulting superabsorbent material has strong antimicrobial activity. Optionally, the treatment solution may also contain a metal salt, including those of zinc, zirconium, and magnesium.
    Type: Grant

  • Patent number: 8926999
    Abstract: This invention pertains to method for imparting a durable antimicrobial activity to substrates, particularly textiles. An acetate-free metal and peroxide antimicrobial treatment formulation is prepared from a metal derivative, hydrogen peroxide and a source of hydroxide ion. The substrate is treated with the composition and dried to afford the treated substrate with antimicrobial activity. Zinc salts, ions, or complexes are preferred.

  • Publication number: 20130011491
    Abstract: This invention pertains to method for imparting a durable antimicrobial activity to substrates, particularly textiles. An acetate-free metal and peroxide antimicrobial treatment formulation is prepared by adjusting the pH of a mixture of a metal salt in aqueous hydrogen peroxide to about 7.5. The substrate is treated with the composition and dried to afford the treated substrate with antimicrobial activity. Zinc salts, ions, or complexes are preferred.

  • Patent number: 8227017
    Abstract: A system and method of enhancing the antimicrobial and biofilm-resistant efficacy of surfaces that have cationic polyelectrolytes nonleachably bound thereto in order to impart antimicrobial activity to the surface. The system for enhancing antimicrobial efficacy involves brushing, dipping, wiping, spraying, or storing the surface in a solution containing citrate ion. The method involves treatment of the surface with a solution which enhances the antimicrobial and biofilm-resistant efficacy of the surface, and which prevents a loss of the antimicrobial properties of the surface which may occur over time. Preferably, the enhancement agent is citrate ion and the cationic polyelectrolyte is poly(diallyldimethylammonium chloride), also known as polyDADMAC. The system is particularly beneficial for surfaces of articles such as contact lenses.

  • Patent number: 8092854
    Abstract: A method of bonding an antimicrobial cationic polyelectrolyte to the surface of a substrate is described, wherein the antimicrobial thus attached to the substrate provides the substrate with antimicrobial properties, and at least a portion of the bonded antimicrobial is substantially non-leachable during normal conditions of use and storage. A method of manufacturing an antimicrobial material is described which comprises exposure of the substrate to a solution of antimicrobial cationic polyelectrolyte, followed by drying the exposed substrate thoroughly to impart a non-leaching property to at least a portion of the antimicrobial cationic polyelectrolytes.
