Definitions

  • the present invention relates to detergent compositions comprising sensory enhancing ingredients
  • the sensory enhancing ingredients provide improved sensory perceptions including improved mildness, and a feeling of freshness and coolness on the skin especially when used in granular detergents for handwash operations
  • Detergent compositions in the form of synthetic detergent granules and liquids are used in may areas throughout the world for purposes of laundering soiled clothes In areas in which mechanical washing machines are not prevalent, laundering soiled clothes generally entails some sort of handwashing operation Such geographic areas use detergent compositions in granular, paste, gel, or bar form In operations involving hand laundering, the hands and arms of the user are typically exposed to the aqueous wash solutions in which the detergent composition is contained Repeated exposure to wash solutions during handwashing operations can lead to skin irritation which can eventually lead to skin lesions, itching, burning, cracking or other skin damage Many attempts have been made by formulators of handwash laundry detergents to alleviate the detrimental effects of hand laundering operations on the arms and hands of users of such detergent products It is therefore desirable to have a laundry detergent composition suitable for handwash operations which exhibits mildness toward the skin of users while maintaining cleaning performance
  • the present invention relates to detergent compositions that signal mildness to the consumer during the wash and thereby significantly improve consumer acceptance of such compositions
  • the present invention also relates to detergent compositions that improve the consumers' overall experience through the handwash process
  • compositions containing conventional surfactant systems By the present invention it has now been discovered that by adding sensory enhancing ingredients to detergent compositions containing conventional surfactant systems, the resulting compositions are perceived to be milder than compositions without the sensory enhancing ingredient These compositions also impart a freshness and coolness to the wash solution and consumers' skin during the wash Additionally, the sensory enhancing ingredients do not have a detrimental impact on the cleaning performance ofthe compositions
  • the present invention solves the long-standing need for a simple, effective, hand wash detergent composition which delivers superior cleaning and provides a mild and fresh skin feel during and after the wash
  • the present invention relates to detergent compositions comprising from 0 01% to 1 0% by weight of the total composition, of a sensory enhancing ingredient, preferably 0 01%) to 0 5% by weight of the total composition, most preferably 0 01 % to 0 1% by weight of the total composition and from about 99 0% to about 99 99%, preferably from about 99.50% to 99 99%, and most preferably 99 90%o to about 99 99% of conventional laundry ingredients selected from the group consisting of surfactants, builders, chelants, brighteners, bleaching ingredients, photobleaches, enzymes, soil release polymers, dye transfer inhibitors, fillers, perfumes and mixtures thereof

  • a sensory enhancing ingredient is an ingredient that when added to a detergent composition creates a physiological sensation of freshness and coolness on the skin ofthe hands and arms when the detergent composition is dissolved in the wash water While not wishing to be bound by theory, it is believed that the sensory enhancing ingredients enhance the perception of coolness on the nerve's endings ofthe skin by binding with calcium (Ca) ions and reducing their transport through the cellular membrane A low level of Ca ions increases the frequency of discharge ofthe neurons sensible to cold, and as a consequence creates a cooling sensation
