To obtain a liquid detergent composition which is excellent in dispersion stability of a silicone and in adhesion to an object to be cleaned by compounding a polyoxyethylene alkyl or alkenyl ether as a nonionic surfactant with an anionic surfactant and an organopolysiloxane.

A nonionic surfactant used is represented by formula I, satisfies formula II, and has an HLB of 10 or higher, In formula I, R is 10-18C alkyl or alkenyl; and n is the number of moles of ethylene oxide added, In formula II, nMAX is the number of moles of ethylene oxide added having a highest wt.%; and Yi is the wt.% of a polyoxyethylene alkyl ether added in an amount of i mol. Preferably, the anionic surfactant is selected from among sulfonates, sulfates, carboxylates, N-acylglutamates, derivatives of these salts, and N-acyl-N- alkylamino acids and their salts.
