A stable liquid detergent composition having improved clay soil detergency, clay soil anti-redeposition, oily soil anti-redeposition and soil release properties is disclosed. The detergent composition is comprised of an anionic surfactant, a nonionic surfactant, a hydrotrope, a graft copolymer of polyalkylene oxide and an ester monomer, and a nonionic cellulosic anti-redeposition agent. The graft copolymer is comprised of (a) a polyalkylene oxide based upon an alkylene oxide having from 2 to 4 carbon atoms having a molecular weight of 300 to 100,000 and, (b) at least one vinyl ester derived from a saturated monocarboxylic acid containing 1 to 6 carbon atoms, and/or methyl or ethyl ester of acrylic or meth-acrylic acid in a weight ratio of (a):(b) of from 1:0.2 to 1:10. The nonionic cellulosic anti-redeposition agent is preferably hydroxypropyl methylcellulose. There is a synergism between the nonionic anti-redeposition agent and the graft polyol which imparts improved clay soil detergency, clay anti-deposition and oily soil anti-redeposition properties to the detergent composition.
