Abstract (en)
[origin: WO9629389A1] The invention concerns the production of compressed washing or cleaning agents of high apparent density: a pre-mixture of washing agent components containing anionic surfactants, non-ionic surfactants, builders, and (optionally) alkalisation agents is produced and compressed; more than 50 wt.% of the non-ionic surfactants are fatty acid alkylester alkoxylates of formula (I): R<1>-CO2-(AO)m-R<2>, (II): R<2>-CO2-(AO)m-R<1> or (III), in which: R<1> stands for a branched or straight-chain, saturated or unsaturated alkyl group with 5-21 carbon atoms; R<2> stands for hydrogen or a straight-chain or branched alkyl group with 1-6 carbon atoms; R<3>, R<4> and R<5> can be identical or different and can stand for hydrogen or the group (a) shown, in which R<6> can be a branched or straight-chain, saturated or unsaturated alkyl group with 5-21 carbon atoms; (a condition is that R<3>, R<4> and R<5> may not all be hydrogen); AO stands for a C2-C4 alkylene oxide unit; m, n, o and p can be identical or different and stand for a number between 1 and 60, preferably 1 and 30, in particular 3 and 12. The process yields washing and cleaning agents of high pouring density and good solubility, without any deterioration in washing power.
