  • Publication number: 20020111285
    Abstract: A rinse-added fabric treatment composition having a rinse aid increases the rinse capacity of an aqueous rinse bath solution for removing laundry residue from laundered fabrics. When properly diluted in water, the rinse-added fabric treatment composition provides a rinse bath solution having a rinsing capacity of greater than 1. In addition, a rinse-added fabric treatment composition reduces the surfactant residue on a fabric, and includes from about 0.05% to about 10% of a residue reduction agent, a suds suppresser, and the balance adjunct ingredients. The residue reduction agent is selected from a cationic residue reduction agent, a zwitterionic residue reduction agent, and a combination thereof. Moreover, methods for reducing surfactant residue on fabric and a method for reducing the amount of water used in a rinsing step of a laundry process are included. A kit for improving the rinsing capacity of water includes a rinse-added fabric treatment composition and an instruction set.
