<p>The present invention provides a microencapsulated insecticide which is prepared by oil-in-water interfacial polymerisation, wherein said insecticide is a solid insecticide at room temperature and pressure and having limited solubility in organic solvents. Various delivery systems for delivering the microencapsulated to a companion animal are also described. A preferred delivery system is an organic dispersion of the microencapsulated insecticide, wherein an oil-in-water-in-oil emulsion is prepared by emulsifying the product of the interfacial oil-in-water polymerisation method in a continuous organic phase.</p> |
