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.

Alkanediol bisacetals useful as surface-active substances for industrial purposes, in particular in washing and cleaning agents, have the formula I ##STR1## where R.sup.1 is alkyl or alkenyl of from 6 to 30 carbon atoms,

Alkanediol bisacetals

1,1-Dialkoxy-2-oxo-6-aryl-3,5-alkadienes of the general formula I ##STR1## where Ar is a phenyl, biphenyl or naphthyl radical which may be substituted by one, two or three C.sub.1 -C.sub.4 -alkyl groups, C.sub.1 -C.sub.4 -alkoxy groups, hydroxyl groups, phenoxy groups, amino groups which may be mono- or di-C.sub.1 -C.sub.4 -alkyl-substituted, halogen atoms or a methylenedioxy group, the substituents being identical or different,
