Summary:The inventive method for producing granulated or powdery detergent compounds consists in producing a detergent base powder by drying washing powder slurries and is characterised in that it consists inadding into slurries a copolymer obtainable by radical copolymerisation of (A) 50-99.5 mol % monoethylenically unsaturated monocarboxylic acid and/or the salt thereof, (B) 0.5-20.0 mol % monoethylenically unsaturated alkoxylated monomer of formula (I), wherein the variables have the following significances: R1 is hydrogen or methyl, R2 is R2 -(CH2)x-O-, -CH2-NR5-, -CH2-O-CH2-CR6R7-CH2-O- or -CONH-, R3 is C2-C4 alkylene identical or different radicals arrangeable by blocks or at random, the ethylene radicals proportion is at least equal to 50 mol %, R4 is hydrogen, C1-C4-alkyl, -SO3Mor -PO3M2, R5 is hydrogen or -CH2-CR1=CH2; R6 is -O-[R3-O]n-R4, wherein -[R3-O]n radicals differ from other -[R3-O]n radical contained in the formula (I), R7 is hydrogen or ethyl, M is alkalimetal or hydrogen, n ranges from 4 to 250, x
