  • Patent number: 6462013
    Abstract: An isotropic liquid detergent composition comprising at least one surfactant and from about 0.1 to about 75 weight percent, based on the total weight of the liquid detergent composition, of a water-soluble or water-dispersible polymer having pendant acid functionality and a terminal fragment of a chain transfer agent, wherein the polymer is the polymerization product of a ethylenically unsaturated acid monomer and a C1 to C24 chain transfer agent. Unexpectedly, these polymers are compatible in isotropic liquid detergent formulations. When these polymers are used in a laundering process, they remove soil from textiles, inhibit soil redeposition onto textiles, and function as cobuilders by complexing metal ions present in hard water such as calcium and magnesium which otherwise may complex with the surfactants of a liquid detergent rendering the surfactants water-insoluble.
