DETERGENT COMPOSITIONS AND METHODS FOR CLEANING

摘要

A detergent composition which produces a signal on contact with water to indicate to the user that the detergent composition is at least partially dissolved and chemical cleaning can commence. The advantage is that the user can delay the start of mechanical cleaning until this time, thereby maximising efficiency of the mechanical cleaning. The signal is preferably an audible signal. The invention also includes a method for washing using such detergent compositions and use of such detergent compositions.
