Laundry detergent compositions that provide soil release benefits to all fabric comprising an organophosphorus soil release agents and optional non-cotton secondary soil release agents. The present invention further relates to a method for providing soil release benefits to cotton fabric by contacting cotton articles with a water soluble and/or dispersible organophosphorus material. The contacting can be during washing or by pretreating by applying the composition directly to stains or by presoaking the clothing in the composition prior to washing. The present invention further relates to providing soil release benefits to all fabric in the laundry wash load in the presence of a bleaching agent.
