Abstract
A non-tower process for continuously preparing granular detergent compositions having a density of at least of about 600 g/l comprises the steps of (a) dispersing a surfactant, and coating the surfactant with fine powder having a diameter from 0.1 to 500 microns, while wetting the surfactant coated with the fine powder with finely atomized liquid, in a mixer, wherein first agglomerates are formed and (b) granulating the first agglomerates in one or more fluidizing apparatus.
