Abstract: Disclosed is an emulsifiable concentrate composition characterized by containing not less than 0.5% by weight but not more than 50% by weight of a hydrophobic agrochemically active compound, not less than 5% by weight but not more than 15% by weight of a surfactant, not less than 2% by weight but not more than 60% by weight of an aromatic hydrocarbon solvent, not less than 2% by weight but not more than 40% by weight of methyl oleate, and not less than 12% by weight but not more than 90% by weight of 1,3-dimethyl-2-imidazolidinone. The emulsion composition is also characterized in that the weight ratio of 1,3-dimethyl-2-imidazolidinone to methyl oleate is within the range from 1:0.03 to 1:2.
