摘要：To provide: a water-soluble amphoteric copolymer having excellenthydrophilicity and high adsorption capability, and capable of exhibiting dramaticallyexcellent dispersibility even under high hardness conditions and being preferably used ina detergent composition application, for example; an application thereof; and aproduction method of such a water-soluble amphoteric copolymer. A water-solubleamphoteric copolymer produced by a copolymerization of a monomer componentcomprising a cationic monomer (a), an anionic monomer (b), and an unsaturatedpolyalkylene glycol monomer (c), wherein the monomer (b) is a carboxyl group-containing monomer and/or a sulfonic acid group-containing monomer (d), and themonomer (b) is more than 50% by mole relative to 100% by mole of a total amount ofthe monomers (a), (b), and (c) if the monomer (b) consists of the carboxyl-group
containing monomer, and at least one species of monomer among the monomers (a), (d),and (c) is 30% by mole or less relative to 100% by mole of a total amount of themonomers (a), (d), and (c) if the monomer (b) comprises the sulfonic acid group-
containing monomer (d).
