Abstract
A rinse-added fabric treatment composition for reducing detergent residue and/or for improving the color and/or clarity of the rinse solution contains an agent for removing residual detergent surfactants from laundered fabrics and an appearance-enhancing selected from a peroxygen bleach, bluing agent and mixtures of the same. An antifoaming or suds suppressing material is optional but highly preferred for reducing the formation of suds during the rinsing of the laundered fabrics. Moreover, methods and uses of the compositions for improving the color and/or clarity of the rinse solution are included. A fabric treatment product for reducing detergent residue and/or for improving the color and/or clarity of the rinse solution includes a rinse added fabric treatment composition, a container for the composition and set of instructions concerning the use of the composition to improving the color and/or clarity of the rinse solution.
