PURPOSE: To obtain a uniform and excellent solidifying agent useful for various organic liquids by addition of a small amount, having excellent stability to long-term preservation and change in temperature, comprising a prescribed dialkylurea derivative as an active ingredient.
CONSTITUTION: This solidifying agent comprises a dialkylurea of the formula (R is a 2-18C saturated alkyl) as an active ingredient obtained by subjecting (A) a diaminocyclohexane, preferably 1,2-diaminocyclohexane and (B) a 2-18C saturated alkyl group-containing alkyl isocyanate (e.g. dodecyl isocyanate) to addition reaction, for example, at a room temperature or under cooling with ice for 1-5 hours. The organic liquid is preferably an animal or vegetable oil, an ester, a polyol, an ether, an alcohol or a hydrocarbon-based oil agent.
