20110064778 | CONTINUOUS MULTI-MICROENCAPSULATION PROCESS FOR IMPROVING THE STABILITY AND STORAGE LIFE OF BIOLOGICALLY ACTIVE INGREDIENTS - The invention relates to microcapsules, and a continuous micro-encapsulation water-in-oil-in-water microencapsulation process through in situ and interfacial polymerization of the emulsion. The formulation comprises a continuous water phase having a dispersion of microcapsules which contain oil drops and wherein the inside of each oil phase drop—containing optionally oil-soluble materials—there is a dispersion of water, or aqueous extract or water dispersible material or water soluble material. The oil drops are encapsulated with a polymerisable material of natural origin. Such microcapsules are appropriated for spray-dry processes, to be used as dry powder, lyophilised, self-emulsifiable powder, gel, cream and any liquid form. The active compounds included in the microcapsules are beneficial to the health and other biological purposes. Such formulations are appropriate to be incorporated in any class of food, especially for the production of nutraceuticals, as well as cosmetic products (such as rejuvenescence creams, anti-wrinkle creams, gels, bath and shower consumable products and sprays).

20120004104 | OIL DISPERSIONS OF nAChR BINDING NEONICOTINOIDS - 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. The formulations this way produced show excellent storage stability properties regarding physiochemical parameters, including stability of the neonicotinoid active ingredient, reduced bleeding, and complete redispersibility. Further, they show excellent biological efficacy due to the reduced and homogeneous particle size below 2 μm when diluted—emulsified—in water. | 01-05-2012 |
20120157315 | AGROCHEMICAL FORMULATIONS OF MICROCAPSULES FOR COMPOUNDS CONTAINING CARBOXAMIDE GROUPS - The present invention consists in microcapsules, uses and method 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 in that their wall contains a mixed polymer glycoluril-polyurea, wherein the polyurea groups come from a urea-formaldehyde resin and not from isocyanates in the form of monomers or prepolymers, being used in the process of making such microcapsules a dispersant in the oil phase of the type of block copolymer of vinylpyrrolldone/vinylalkene and/or vinylpyrrolidone/vinyl acetate and the microencapsulation reaction may be carried out without the presence of any polyamine/polyol acting as catalyst of the reaction of polyurea/polyurethane as it is the prior art. | 06-21-2012 |
