PROBLEM TO BE SOLVED: To provide an aqueous composition capable of decreasing equilibrium and dynamic surface tension, particularly a composition for coating materials, inks, storage liquids, adhesives, fertilizer and photoresist development/electronics cleaning. SOLUTION: An alkylated amino alkyl piperazine compound expressed in formula I is blended by the quantity enough to decrease the surface tension. (In the formula, one of R1 and R2 represents a 5-14C alkyl or cycloalkyl group and the remainder represents H or both of R1 and R2 represent a 5-8C alkyl group and (n)/represents 2 or 3.).
