Abstract (en)
[origin: ES8609454A1] A process for the production of a granular, free-flowing detergent composition which is rapidly soluble in water, and the product thereof which has a bulk density of at least 600 g/l and a particle size of 0.1-2 mm, wherein an aqueous slurry of the composition ingredients is continuously homogenized to yield a viscosity of 4,000 to 20,000 mPa.s and heated to a temperature of 85 DEG -105 DEG C. The homogenized heated slurry is then sprayed in a drying tower through nozzles having a bore diameter of 2.5-5 mm under a pressure of 20-45 bar. The slurry and resulting product contain 10-28% alkoxylated nonionic surfactant, 40-80% inorganic carrier and 0.5-10% organic washing auxiliary.
