(57) [Summary] [Purpose] Having a specific range of molecular weight cut-off and copolymer composition, Provided are a detergent composition, an inorganic pigment dispersant, and a fiber treating agent containing a maleic acid-based copolymer having a high calcium ion-capturing ability, a good clay-dispersing ability, and a low gelling property. [Constitution] The molecular weight cut-off by gel permeation chromatogram is a specific ratio, and the molecular weight cut-off is A maleic acid / (meth) acrylic acid-based copolymer having a specific ratio of a copolymerization ratio, and a detergent composition, an inorganic pigment dispersant, and a fiber treatment agent containing the polymer. |
