  • Publication number: 20140093550
    Abstract: A system of stabilized metallic nanoparticles is described that includes metallic nanoparticles coated with a hydrophilic polymer that has been reacted with a catechol-based ligand. Also described are stable, metallic nanoparticles that can be used alone or in conjunction with biocides, antibiotics, or other treatment systems in a method to disrupt a biofilm and facilitate its removal from a surface. The nanoparticles can be metal, such as platinum, silver, iron (II, III) oxide (Fe3O4), and gold. The nanoparticles can be sterically stabilized, such as with a polymer, or charge stabilized, such as with citrate, resulting in nanoparticles having modified surfaces. This surface modification is thought to enhance the stability of the nanoparticles and decrease their likelihood of aggregation, which, in turn, enhances their ability to disrupt and disperse existing biofilms.

    Abstract: This disclosure concerns the control of the retention and/or persistence of a biologically active compound (e.g., a pesticide) in soil. In some embodiments, the use of polymer-coated particles comprising a biologically active compound leads to increased persistence of the compound in a target zone to which a composition comprising the particles is applied.

  • Patent number: 8329628
    Abstract: A personal cleansing composition includes a surfactant, a thickener, emulsifier and at least one particulate dispersed in the thickener, the at least one particulate being formed of a substantially biodegradable substance. The at least one particular may include a soy meal based polymer. The soy meal based polymer is both stable and biodegradable. The at least one particulate includes a group of suspended particles added to mechanically scrub the skin of a user or used as a textural ingredient to modify the feel, spreadability or slip of a product. The soy meal based polymer is useful in personal cleansing compositions as an exfoliant, a scrub, a film former or as a filler. The half-life of the composition may be modified as necessary based on the shelf-life of the product.

  • Publication number: 20120263776
    Abstract: A method for obtaining non-water-soluble powders comprising antimicrobial activity and having quaternary ammonium salts adhered thereto. The invention also includes the powders thus obtained and the use thereof as antibacterial agents. The invention enables the production of non-soluble organic or inorganic powders having a particle size of 5 to 500 ?m, having a quaternary ammonium salt adhered to the surface thereof and fixed on the surface. When deposited on textile materials, the powders enable bacterial and viral decontamination, by means of filtration, of polluted water or aqueous environments. Textile materials impregnated with powders according to the invention can be used in the production of breathing masks, protective garments or other items, in particular in a hospital environment. The antibacterial properties of the powders are at least twice as high as the antibacterial properties of the same quaternary ammonium salt used in isolation.

  • Publication number: 20120039979
    Abstract: An insect control substance for controlling certain flying insect pests in proximity to the substance includes a rubber crumb carrier having a plurality of rubber particles and a volatile hydrophobic semiochemical for attracting certain flying insect pests absorbed within the rubber particles forming a discontinuous phase of the substance. The insect control substance also includes a body of water forming a continuous phase of the substance within which the discontinuous phase is suspended. When the insect control substance is applied to an application surface the discontinuous phase is exposed to the surrounding air and the semiochemical within the rubber particles evaporates into the air around the application surface and attracts the flying insect pests to the rubber crumb carrier to facilitate control of the flying insect pests.

  • Publication number: 20110262514
    Abstract: It is provided smooth polyurethane particles for oil absorption under producing, treating, keeping and transporting. A polyurethane particle consists of a body of the polyurethane particle and hydrophilic fine silica powders existing on the body. The body is obtained by three-dimensionally polymerizing an isocyanate-terminated urethane prepolymer with trifunctional or more functional amines. The isocyanate-terminated urethane prepolymer is obtained by reacting polyisocyanates and polyols including a poly(tetramethylene ether)glycol. The polyurethane particles are obtained by spray-drying a mixed aqueous dispersion in which the hydrophilic fine silica powders and the polyurethane spheres are dispersed in water.

  • Patent number: 8039015
    Abstract: Microcapsules possessing Lewis acid-Lewis base salt walls incorporate water-immiscible materials, such as N,N-diethyl-m-toluamide (DEET), as a core component. Such microcapsules, or similar microcapsules incorporating other core components, may be made by emulsifying a water-immiscible core component in an aqueous solution of one wall-forming reactant, such as the Lewis base, and then mixing that solution with the other wall-forming reactant, such as the Lewis acid. Various adjuvants may be included with the core component to contribute additional characteristics, such as enhancement of a controlled release characteristic or improved mechanical stability.

  • Patent number: 8025894
    Abstract: The present invention relates to a new formulation characterised by the presence of two components, one of which (A) possesses insecticidal, acaricidal, fungicidal, snailcidal or vermicidal activity and the other (B) exhibits synergistic activity with the first by enhancing its effectiveness, and in which the average release time of component (A) is 1 to 12 hours later than the average release time of component (B). The formulation is obtained by: a) separate microencapsulation of both components (A) and (B) within a multilayer system of specific polymers in which component (A) is in a more interior portion of the capsule than component (B), being separated from component (B) by a polymer layer of suitable thickness (FIG. 1); b) microencapsulation of both components within a single layer system (FIG. 2), combined with an immediate-release emulsion/microemulsion containing an additional amount of component (B).
