Title:
HIGH-DENSITY POWDERED DETERGENT COMPOSITION
Document Type and Number:
WIPO Patent Application WO/1997/027278
Kind Code:
A1
Abstract:
A high-density powdered detergent composition having a bulk density of 0.6 to 1.2 g/ml, which comprises 0.5 to 30 wt.% of a glycine-N,N-diacetic acid derivative (a), 5 to 45 wt.% of a nonionic surfactant (b) having an HLB value of 10.5 to 15.0, 0.5 to 18 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 90:1 and 60:40. This composition contains a glycine-N,N-diacetic acid derivative, which is a builder excellent in biodegradability and metal-sequestering power, together with an inorganic builder such as zeolite or crystalline silicate, and exhibits high detergency.
