Abstract
A manganese exchanged Zeolite A laundry bleach activator is made in a single reaction vessel by mixing dry Zeolite A with an inorganic acid in an amount to lower the pH to 8.0-10.5, adding and mixing in an aqueous manganese (II) salt, adding and mixing in a chelating agent such as sodium tripolyphosphate, adding and mixing in a binding agent such as carboxymethylcellulose, mixing and adding water to cause the Mn-exchanged Zeolite A, chelating agent and binder to agglomerate to form small granules and drying the resulting small granules for use as a bleach activator in laundry detergent compositions.
