Abstract (en)
[origin: EP0351937A1] A granular detergent composition or component therefor having a bulk density of at least 650 g/litre is prepared by granulating a particulate material, preferably spray-dried, in a high-speed mixer/granulator having both a stirring action and a cutting action, in the absence of an agent for improving surface properties. The particulate starting material comprises (a) from 12 to 70 wt% of non-soap detergent-active material (preferably consisting at least partially of anionic detergent-active material) and (b) at least 15 wt% of water-soluble crystalline inorganic salts, including sodium tripolyphosphate and/or sodium carbonate, the weight ratio of (b) to (a) being at least 0.4:1.
