The present invention provides a liquid detergent composition containing a specific amount of surfactant (A); a specific amount of a polymer compound (B) having the polyether chain moiety (i) and the polymer chain moiety (ii) composed of polymerization units derived from the specific unsaturated monoethylenic monomer; and water, wherein component (A) contains a specific amount of a specific alkoxyl nonionic surfactant (a1), and component (B) is a polymer compound having the polyether chain moiety (i) composed of polymerization units derived from an epoxide having 2 to 5 carbon atoms and the polymer chain moiety (ii) composed of polymerization units derived from one or more unsaturated carboxylic acid monomers selected from acrylic acid, methacrylic acid and maleic acid, the polymer compound having a graft structure wherein one of the chain moieties (i) and (ii) is the main chain and the other is a side chain.

Liquid detergent composition

The invention provides a liquid detergent composition containing (a) a nonionic surfactant obtained by adding ethylene oxide and an alkylene oxide with from 3 to 5 carbon atoms to a compound represented by R&#x2014;OH (wherein R represents an alkyl group or an alkenyl group with from 8 to 18 carbon atoms) under a specified condition, (b) an anionic surfactant and (c) a water-miscible organic solvent in specified ratios, respectively.
