An α-SF salt-containing liquid detergent having excellent low-temperature stability and high viscosity is provided. An α-sulfo fatty acid alkyl ester salt having 16 to 18 carbon atoms in a fatty acid residue (a), a sulfonic acid type anionic surfactant other than (a), a sulfate type anionic surfactant, and a nonionic interface It contains at least one (b) selected from the group consisting of activators and unsaturated fatty acid salts (c) having 16 to 22 carbon atoms, and the content of (c) is 1.2 to 7.5% by mass. Yes, the total content of (a) and (b) is 8 to 30% by mass, the content of (a) is 50% by mass or less with respect to the total amount of (a) and (b), When (b) does not contain or contains linear alkylbenzene sulfonate (b1) and contains (b1), it contains (b) other than (b1), and (b) other than (b1) (B1) / {(b)-(b1)} representing the mass ratio of (b1) to the total content is 2 0 or less, the liquid detergent.
