20150010635 | CONTROLLED RELEASE PARTICLES, WOOD TREATMENT AGENT, AND PRODUCING METHOD THEREOF - Controlled release particles are obtained by dissolving a hydrophobic antibiotic compound with a hydrophobic polymerizable vinyl monomer to prepare a hydrophobic solution, blending water with an emulsifier to prepare an aqueous emulsifier solution, emulsifying the hydrophobic solution in the aqueous emulsifier solution, and polymerizing the polymerizable vinyl monomer by mini-emulsion polymerization in the presence of a polymerization initiator, thereby producing a polymer containing an antibiotic compound and having an average particle size of below 1 μm. | 01-08-2015 |
20130337072 | CONTROLLED RELEASE PARTICLES AND PRODUCTION METHOD THEREOF - A controlled release particle includes a core containing an antibiotic compound, and a shell covering the core. The controlled release particle is obtained by a production method including a first step in which a first component containing an antibiotic compound and a polymerizable vinyl monomer is subjected to suspension polymerization to form the core containing the antibiotic compound and a polymer of the polymerizable vinyl monomer; and a second step in which a second component containing a shell-forming component is subjected to interfacial polymerization to form a shell, wherein in the second step, the interfacial polymerization is started simultaneously with the start of the suspension polymerization of the first step, or started after the start of the suspension polymerization of the first step. | 12-19-2013 |
20120172334 | CONTROLLED RELEASE PARTICLES AND METHOD FOR PRODUCING THE SAME - Controlled release particles are obtained by dissolving a hydrophobic antibiotic compound in a hydrophobic polymerizable vinyl monomer without the presence of a solvent, thereby preparing a hydrophobic solution, the hydrophobic antibiotic compound having a melting point of 100° C. or less, a polar term δp,compound of 2 to 8 [(J/cm | 07-05-2012 |
20100069439 | MICROORGANISM CONTROL AGENT AND STABILIZING METHOD - Disclosed is a microorganism control agent containing not less than 1% by weight but less than 10% by weight of N,N′-hexamethylenebis(4-carbamoyl-1-decylpyridinium bromide), not less than 35% by weight but less than 60% by weight of at least one alcohol having 2 or 3 carbon atoms, water and an acid. | 03-18-2010 |
