A synergistic mixture for promoting soil release from fabric, under laundry washing conditions, which comprises a polyacrylate polymer and at least one water soluble modified cellulose ether. The polyacrylate polymer comprises: (i) 90-100 weight % of polymerized units derived from acrylic acid and (ii) up to 10 weight % of polymerized units derived from one or more C3-C8 monoethylenically unsaturated carboxylic acids, based on the total weight of said polyacrylate polymer. A laundry formulation is also provided which contains the synergistic mixture in an amount of up to 2 weight %, based on the total weight of the laundry formulation. Also provided are methods of promoting soil release from soiled fabric which involve contacting the soiled fabric with an aqueous solution comprising the above-described inventive synergistic mixture or with the above-described laundry formulation.
