OIL-IN-WATER PESTICIDE COMPOSITION AND ITS PRODUCTION

Japanese Patent JP3284569

B2

PURPOSE: To provide the subject composition easy to prepare in the form of an emulsion from an original form of pesticide, also causing no crystallization of the pesticide in the emulsion with longterm stable dispersion of emulsified droplets, thus excellent in preservability for a long period.
CONSTITUTION: Part of an aqueous phase is added to a mixture of (A) poorly soluble or insoluble original form of a pesticide ≤100°C in melting point and ≤0.5wt.% in the solubility at 20-25°C in water and (B) a surfactant, and, in case said original form is solid at normal temperatures, furthermore (C) an oily phase containing an organic solvent pref. ≤10wt.% in the solubility in water at 20°C to form a gelled product. The rest of the aqueous phase is then added to this product to effect phase inversion from water-in-oil type to oil-in- water type, thus easily obtaining the objective composition having the original pesticide effect without no problems such as dusting in use and flash ignition danger in the production, transportation and storage etc. The preferable amounts of the components are as follows:A=1-60wt.% (esp. 1-50wt.%); B:1-30wt.% (esp. 5-20wt.%);andC=0-50wt.% (esp. 5-40wt.%).
