  • Patent number: 9006145
    Abstract: The present invention is directed towards microcapsules, uses and methods of microencapsulation with improved properties regarding agglomeration, bleeding and control of the reaction. The invention is especially suitable for chemical compounds with at least one carboxamide group, preferably for microencapsulation of those compounds wherein the carbonyl group is attached to a nitrogen atom or nitrogenated heterocycle and wherein the microencapsulation reaction may be too vigorous. The microcapsules are characterized by a mixed glycoluril-polyurea polymer wall, wherein the polyurea groups come from a urea-formaldehyde resin and not from isocyanate monomers or prepolymers. The process of making such microcapsules a dispersant in the oil phase of the type of block copolymer of vinylpyrrolidone/vinylalkene and/or vinylpyrrolidone/vinyl acetate and the microencapsulation reaction may be carried out without the presence of any polyamine/polyol acting as a catalyst.

  • Publication number: 20140221212
    Abstract: Controlled release of one or more agricultural chemicals is provided by microcapsules adapted to rupture in a magnetic field. The microcapsules, which may be applied to soil, seeds and/or plants, each have a shell that encapsulates an agricultural chemical, such as a fertilizer, herbicide or insecticide. One or more organosilane-coated magnetic nanoparticles is/are covalently bound into the shell of each microcapsule. For example, (3-aminopropyl)trimethylsilane-coated magnetite nanoparticles may be incorporated into the shell of a urea-formaldehyde (UF) microcapsule during in situ polymerization. In one embodiment, microcapsules encapsulating a fertilizer are applied during seed planting. Controlled release is subsequently triggered after an appropriate period of dormancy by positioning a magnetic field generating device proximate the microcapsules to generate a magnetic field sufficient to rupture the microcapsule shells through magnetic stimulation of the organosilane-coated magnetic nanoparticles.

Thus, the active ingredient (for example, 1-MCP complex powder) is imbedded in the resin matrix spheres, and the hydrophobic particles, which also serve as Pickering emulsifier to stabilize the matrix spheres, form a coating layer around the matrix spheres to provide protection against water. Thus, the sphere is composed of the “Pickering” particle and resin matrix, in which the active ingredient is imbedded.

  • Patent number: 8263327
    Abstract: The present invention provides a process for producing microcapsules. The microcapsules have an effect-substance-containing capsule core and a polymer-containing capsule covering. The capsule covering is formed by enzyme-catalyzed polymerization of monomers which are present in an inverse miniemulsion, as well as microcapsules and dispersions. The present invention also provides for using the microcapsules and microcapsule dispersions as components in colorants, cosmetics, pharmaceuticals, crop protection agents, fertilizers, and additives for foods or animal feed.

  • Publication number: 20120065070
    Abstract: An object of the present invention is to provide a technique for producing a microcapsule containing a pesticidal compound in a fatty acid ester such as methyl O-acetylricinoleate, which delays the release timing of the pesticidal compound as compared to a conventional microcapsule. Provided is a method for producing a microcapsule, which comprises: (1) keeping a mixture of a pesticidal compound, a compound represented by formula (I): wherein X represents —CH2—CH2— or —CH?CH—, R1 represents a C1-C4 alkyl group, and R2 represents a C1-C4 alkyl group, and a polyisocyanate at 20 to 60° C. for 3 hours or more; (2) adding the mixture to water containing a polyol or a polyamine to prepare liquid droplets in the water; and (3) forming a film of polyurethane or polyurea around the droplets.

  • Patent number: 8129313
    Abstract: An aqueous agrochemical composition and in particular an agrochemical concentrate comprises (a) a non-encapsulated aqueous solution or dispersion of an agrochemical and (b) a suspension in said aqueous solution or dispersion of a microencapsulated liquid, water-insoluble, bioperformance-enhancing adjuvant for said agrochemical. The adjuvant suitably has little or no surfactant properties. The invention permits oil adjuvants such as “Turbocharge” and “Brij 92” to be built into agrochemical compositions with which they would normally be incompatible. With certain adjuvants reduced phytotoxicity may be observed.
