To obtain the subject composition capable of improving an effect to a skin and a rinsing property without damaging primary cleaning and foaming properties by blending a hydrophilic polyether-based copolymer in a specific amount to a conventional detergent.

This liquid detergent composition for a hard surface contains (A) 1-70wt.% anionic surfactant, (B) 0.5-20wt.% nonionic surfactant and (C) 0.001-10wt.% hydrophilic polyether-based copolymer having a structural unit of the formula (R1, R2 are each a 1-20C alkyl which may have hydroxyl; Y is a 1-10C alkylene which may have hydroxyl). Thus, a detergent composition of a practical value having an extremely mild effect to a skin and an excellent rinsing property, and not causing a roughness in the skin, can be expected.
