  • the present invention relates to liquid manual dishwashing detergent compositions, which have improved viscous properties. Furthermore, the present invention relates to usage of such liquid manual dishwashing detergents for dish cleaning purposes and a process for cleaning dishes using liquid manual dishwashing detergent compositions according to the present invention.
  • cleaning compositions such as hand dishwashing compositions are those that they should have a certain consistency or viscosity.
  • the desired viscosity expected by the consumer, should not be too thin.
  • the consumer desires viscous formulations allowing a controlled handling (providing good pourability and ease of dissolution in water). Also, the consumer associates viscous cleaning compositions with good performance and quality as well as with high levels of active ingredients.
  • high viscous cleaning compositions areobtained by incorporating gums, polymeric thickeners and/or high levels of salts and/or active matter of surfactants into the cleaning compositions.
  • This approach has the drawback that it negatively affects the formula costs while providing no benefit (apart from thickening).
  • this approach is not sustainable, since cleaning formulations with high levels of polymeric thickeners and/or surfactants are under environmental aspects undesirable.
  • aqueous cleaning composition in particular a hard-surface cleaning composition, which is highly viscous (jelly like) by means of a self- thickening system and which delivers improved cleaning performance (degreasing performance), lather performance (rapid generation of foam, stability of the foam) and solubility in water.
