Abstract
An improved soil release polymer composition comprising a soil release polymer and a long chain nonionic alkoxylate surfactant and/or amphoteric that is able to generate very low critical micelle concentration values in water. Preferably, the soil release composition is incorporated in a detergent system such as a commercial laundry detergent which comprises a second anionic, nonionic or cationic surfactant and mixtures thereof. By lowering the cmc values of the detergent wash water to very low levels, the surfactant greatly enhances the performance of the soil release polymer.
