2. Description of the Related Art Conventionally, emulsions, wettable powders, sols, EWs, and the like are known as formulations of agrochemical active ingredients that are hardly soluble in water. However, since the emulsion and the EW agent use an organic solvent, they have problems such as odor and skin irritation, and the wettable powder also has problems such as dusting. Sols have been proposed to solve this problem. However, sols have the drawback that they cannot be used with pesticidal active ingredients having a low melting point or raw materials having a particle size growing.
