FIELD: detergents.

SUBSTANCE: invention relates to detergent compositions. Described is a detergent liquid composition containing the following components from (A) to (D), in which the weight ratio of component (A) to total amount of component (B) and component (C), i.e. (A/(B+C)) is 0.6 or more and 5 or less; and weight ratio of component (B) to component (C), i.e. (B/C) is 0.05 or more and 1.8 or less: (A)—from 10 to 40 wt % of an internal olefin sulphonate salt, having 16 or more and 18 or less carbon atoms, wherein the content of the sulphonate salt of the internal olefin, having a sulphonate group in the C-2 position, is 5 % by weight or more and 25 % by weight or less, (B)—0.5 to 16 % by weight of a fatty acid salt, represented by following formula (1) R¹COOM (1), in which R¹ is an alkyl group or an alkenyl group having 10 or more and 14 or less carbon atoms; and M represents a hydrogen atom, an alkali metal, alkali-earth metal (1/2 atom), an ammonium or organic ammonium ion, (C) an organic solvent having one or more hydroxyl groups, wherein content of component (C) in liquid detergent composition is from 0.1 to 50 % by weight; and (D) is water.

EFFECT: technical result is excellent stability at low temperatures without reducing detergent power.
