Abstract (en)

[origin: WO9727283A1] A high-density granulated detergent composition having a bulk density of 0.6 to 1.2 g/ml which comprises 0.5 to 30 wt.% of an aspartic acid-N,N-diacetic acid salt (a), 5 to 45 wt.% of a nonionic surfactant (b) having an HLB value of 10.5 to 15.0, 0.5 to 15 wt.% of an anionic surfactant (c), and 1 to 30 wt.% of an aluminosilicate (d), each percentage being based on the total weight of the composition, and in which the weight ratio of the component (b) to the component (c) is between 99:1 and 70:30. This composition contains an organic builder excellent in biodegradability together with an inorganic builder and exhibits high detergency.
