Definitions

  • the present invention is in the field of hard surface cleaning compositions, in particular liquid detergent compositions with improved emulsification and oily soil removal of hard surfaces, such as tableware.
  • Household cleaning activities involve the use of a detergent product and water to rinse off the detergent product and finish the cleaning process.
