Abstract: PROBLEM TO BE SOLVED: To provide a block copolymer having excellent solubilizing capacity and stability upon dilution of the substance to be solubilized, which copolymer is a block copolymer having a structure: A-B-A (wherein A is a polyethylene oxide block, and B is a polymer comprising an olefinically unsaturated quat. ammonium compound) and used as a surfactant. SOLUTION: Block A has an average degree of polymerization of 5-100. Block B contains a polymer comprising a quat. ammonium compound (monomer I) represented by formula (wherein (x) is 5-18; R and R are each a 1-5C alkyl; R is a 1-5C alkyl or a hydroxyalkyl; and X is a halide, acetate or metasulfate ion) or contains a mixture of monomer II represented by formula II (wherein R is Cn H2n+1 ; (n) is 5-18; and X is as defined in formula I) and monomer III represented by formula III (wherein R and R are each a 1-3C alkyl or a 1-3C hydroxyalkyl; and X is as defined in formula I) in a ratio of III to II of 1:20 to 20:1.
