  • Consumer perception and habits determine the trends in consumer products. Consumers have been looking for novel and interesting cues to inform them about the cleaning process in order to be convinced about the effectiveness, performance and reliability of the cleaning. Consumers have demanded to choose a detergent composition according to the cleaning capability of the product. Additionally, consumers have judged the cleaning capability of a detergent composition according to the cues that they receive during the cleaning process. The amount of generated foam, the duration of it, the breeze of a perfume and the presence of suds in detergents are some of the marks that consumers have faith in that the product is working effectively and sustaining its cleaning performance. Therewithal, consumers dose the detergent according to those cues.

  • the color change is observed upon dilution of the cleaner with water in order to mask the reddish brown water color which is perceived as "dirty and unfit for the use" after items are washed or rinsed.
  • This invention indicates to users of the composition that the water is clean by masking the color of the suds and consumers are brought about to make a decision to wash or rinse the items. This masking can be interpreted wrong and consumers may continue to use the cleaning water although it becomes dirty.
