DETERGENT COMPOSITION AND METHOD FOR DETECTING PRESENCE OF A MARKER MOLECULE IN A SOLUTION

摘要

The present invention provides a detergent composition for use in a water-utilizing appliance, that allows for selection of an enhanced mode of operation of the appliance, based on the detection of a marker molecule in the solution of the detergent composition, where the enhanced mode comprises treatment of waste water generated during use of the appliance. The present invention also provides a method of selecting an enhanced mode of operation in a washing machine including a sensor assembly for detecting the presence of a marker molecule in a solution of the detergent composition.
