Title: PROCESS FOR MAKING A DETERGENT COMPOSITION BY NON-TOWER PROCESS
Abstract:
A non-tower process for continuously preparing granular detergent composition having a density of at least about 600 g/l is provided. The process comprises the steps of: (a) dispersing a surfactant, and coating the surfactant with fine powder having a diameter from 0.1 to 500 microns, in a mixer, wherein first agglomerates are formed, and (b) spraying on finely atomized liquid to the first agglomerates in a mixer, wherein second agglomerates are formed. Optionally, the second agglomerates are further subjected to the step (c), i.e., thoroughly mixing the second agglomerates in a mixer.
