  • Patent number: 8293733
    Abstract: Selective insect neonicotinoids is a class of pesticide active ingredients that share some characteristics in their chemical structures and bind to the nAChR acetylcholine receptors. Formulation of such compounds in oil suspension or oil dispersion is challenging due to their electrostatic interactions of the heteroatoms in oily media, that lead to irreversible flocculation or diminished homogeneicity and bleeding of such oil dispersions. Imidacloprid, Thiamethoxam, Thiachloprid, Nitenpyram, Acetamiprid, Clothianidin and Dinetofuran and derivatives thereof with nAChR binding ability are successfully formulated in oil suspension with the use of certain copolymeric anionic fatty-acid based dispersants, sorbitan derivatives, ionic surfactants, other non-ionic surfactants and inorganic polyvalent cationic salt dispersed in the oil.

  • Patent number: 8263530
    Abstract: The invention refers a new formulation of fluoroxypyr or chlorpyrifos or diflufenican microencapsulated and in the form of water dispersable granules or as a part of a ZC formulation. Further the invention refers to water dispersable granules containing microcapsules that enclose fluoroxypyr and at the same time the WDG have also sulfonylureas outside of the microcapsules. Further we provide formulations in the form of SC or ZC of the aforementioned active ingredients and its combinations. Also fluoroxypyr may be replaced by any agrochemical of any biological activity that is solid at room temperature and melts below 110° C. Mixtures of actives of such formulations are also contemplated.

  • Patent number: 8216598
    Abstract: The present invention deals with an alternative interfacial polymerization process of microencapsulation, microcapsule's produced thereof, microencapsulated agrochemicals, pharmaceuticals, catalysts and phase transfer materials, and formulations thereof, by means of microcapsules and starting materials with much lower toxicological profile than customary microencapsulation materials, and with the participation of acetylene carbamide derivatives in the final structure of the microcapsules' wall.
