Process for preparing spray dried detergent compositions

Abstract

Abstract A PROCESS IS PROVIDED FOR PREPARING SPRAY DRIED SUBSTANTIALLY HOMOGENEOUS DETERGENT COMPOSITIONS FROM AQUEOUS SLURRIES CONTAINING SURFACE-ACTIVE ETHYLENE OXIDE ADDUCTS WHEREIN PRIOR TO SPRAY DRYING THE AQUEOUS SLURRY, AN ORGANIC MONO- OR POLYPHOSPHATE ESTER IS INCORPORATED WITH THE SURFACE-ACTIVE ETHYLLENE OXIDE ADDUCT AND OTHER INGREDIENTS EMPLOYED IN THE DETERGENT COMPOSITION, IN ORDER TO INHIBIT THE SLURRY FROM SEPARATING INTO DIFFERENT LAYERS SO THAT THE PARTICULATE DETERGENT COMPOSITION PRODUCTED WILL BE SUBSTANTIZLLY HOMOGENEOUS AND LOW FOAMING AND HAVE GOOD CLEANING POWER. THE PHOSPHATE ESTER MAY BE ADDED TO THE INGREDIENTS OF THE DETERGENT COMPOSITION PRIOR TO, DURING OR SUBSEQUENT TO THE PREPARATION OF THE AQUEOUS SLURRY TO THE INGREDIENTS. DETERGENT COMPOSITIONS ARE ALSO PROVIDED, WHICH CAN BE PREPARED EMPLOYING THE ABOVE PROCESS, CONSISTING ESSENTIALLY OF AT LEAST ONE SURFACE-ACTIVE ETHYLENE OXIDE ADDUCT, AND AN ORGANIC MONO- OR POLYPHOSPHATE ESTER, AND OPTIONALLY, INORGANIC BUILDERS, OPTICAL WHITENERS, CHELATING AGENTS AND DIRT CARRIERS, SUCH AS CARBOXYMETHYL CELLULOSE.
