A liquid detergent comprising: an α-sulfofatty acid alkyl ester salt (a) in which the fatty acid residue has 16-18 carbons; at least one (b) selected from the group consisting of sulfonic acid-type anionic surfactants other than (a), sulfate ester-type anionic surfactants, and nonionic surfactants; and an unsaturated fatty acid salt (c) having 16-22 carbons. With respect to the total mass of the liquid detergent, the content of (c) is 1.2-7.5 mass% and the total content of (a) plus (b) is 8-30 mass%. The content of (a) is not more than 50 mass% with respect to the total amount of (a) plus (b). (b) may or may not contain a linear alkylbenzenesulfonate salt (b1). If (b1) is incorporated, a (b) other than (b1) is incorporated and (b1)/{(b)-(b1)}, which is the mass ratio of (b1) with respect to the total content of (b) other than (b1), is not more than 2.0. |
