Abstract

The present invention relates to a method for producing granular or pulverulent detergent compositions, comprising the production of a detergent base powder by drying an aqueous detergent slurry, which comprises adding to the slurry a copolymer which is obtained by free-radical copolymerization of (A) from 20 to 80% by weight of at least one monomer selected from the group consisting of monoethylenically unsaturated monocarboxylic acids, dicarboxylic acids and dicarboxylic anhydrides, and (B) from 20 to 80% by weight of at least one monomer selected from the group consisting of aliphatic or aromatic monoolefins.
