Claim:
A liquid detergent, comprising: an acrylic acid/maleic acid-based copolymer (salt), wherein the acrylic acid/maleic acid-based copolymer (salt) contains maleic acid (salt) in an amount of 5-90 mol% per mole of the sum of acrylic acid (salt) and maleic acid (salt), and a product (MA×Mw) of a weight average molecular weight (Mw) of the copolymer (salt) and a proportion (MA (mol%)) of the maleic acid (salt) in the copolymer (salt) is 450,000 or less; and a surfactant, wherein the liquid detergent is transparent, has a water content of 1.5 to 50 mass% and a kaolin turbidity of 200 mg/liter or less, and wherein the surfactant is present in an amount of 10-60 mass%, based on the mass of the liquid detergent.
