    Abstract: SOLID BLOCK ALKALINE DETERGENT COMPOSITIONS ARE DISCLOSED COMPRISING A SOURCE OF ALKALINITY, AND OTHER DETERGENT ADDITIVES INCLUDING SEQUESTRANTS. THE SOLID BLOCK DETERGENTS OF THE INVENTION USED A MIXED INORGANIC AND ORGANIC SEQUESTRANT COMPOSITION THAT SUCCESSFULLY SOFTENS SERVICE WATER USED IN MANUFACTURING AQUEOUS DETERGENTS FROM THE COMPOSITION, BUT ALSO OBTAINS SUBSTANTIALLY IMPROVED ORGANIC SOIL REMOVAL ON DISHWARE OR FLATWARE. THE SOLID BLOCK DETERGENTS OF THE INVENTION COMPRISE LARGE MASSES OF THE CHEMICAL INGREDIENTS HAVING A WEIGHT OF GREATER THAN ABOUT 500 GRAMS IN A SOLID BLOCK PRODUCT FORMAT THAT IS TYPICALLY DISPENSED USING A SPRAY ON WATER DISPENSER THAT CREATES AN AQUEOUS CONCENTRATE THAT IS USED IN A WASHING MACHINE.
