Abstract:
2,2'-oxodisuccinate detergent builder salts (ODS), especially tetrasodium 2,2'-oxodisuccinate, are difficult to dry and tend to pick up water due to the hygroscopicity of the 2,2'-oxodisuccinate: yet the present invention secures improved granular built detergent compositions comprising ODS by an aqueous ODS/zeolite coagglomeration process, the resulting agglomerate being remarkably stable and nonhygroscopic. Other detergent ingredients, such as perborate bleach, surfactants and the like, can be dry-mixed with the agglomerates to form fully-formulated granular detergents. The invention encompasses the agglomeration process, the ODS agglomerates and granular detergent compositions containing same.
