ABSTRACT:
A phosphate-reduced, granular free-flowing detergent containing (a) from 5 to 40% nonionic surfactant, (b) from 3 to 20% anionic surfactant, (c) from 15 to 50% zeolite, (d) from 0.5 to 15% homopolymeric or copolymeric carboxylic acid or alkali metal salts thereof and (e) from 10 to 72.5% detergent constituents which are stable under spray-drying conditions, with the proviso that the detergent comprises a mixture of two powder components (A) and (B) in a weight ratio of from 1:5 to 3:1, component (A) containing from 50 to 100% of constituent (a), from 80 to 100% of constituent (c) and from 50 to 100% of constituent (d). Component (A) has an average particle size of from 0.4 to 0.8 mm and a powder density of from 500 to 800 g/l. Component (B) contains from 80 to 100% of constituent (b) and 100% of constituent (e), has a powder density of from 300 to 500 g/l and differs in its particle size distribution by at most 50% from the particle size distribution of component (A).
