Definitions

  • liquid or solid components In the preparation of powder detergents or base powders for further processing into solid detergents (for example extrusion with the addition of further components to granules), up to 30 liquid or solid components must be homogenized as intensively and uniformly as possible in partly very different amounts, which is done by slurrying in water.
  • various components e.g. Surfactants and zeolites used as builders, highly viscous mixtures. Since highly concentrated slurries are desired for the subsequent spray drying, it is necessary to use auxiliaries which lower the viscosity of the slurries.
  • WO-A-91/09932 discloses a process for the preparation of granular detergent compositions in which a deflocculant polymer having hydrophilic polymer backbone and hydrophobic side chains is added to the detergent slurry.
  • the backbone is based on unsaturated monocarboxylic acids, dicarboxylic acids and / or alcohols as monomer units.
  • the side chains which may contain polyalkylene oxide blocks, are attached to the backbone via ester, ether or amide functions.
  • a copolymer of acrylic acid and dodecyl maleate is used.
  • the copolymers used according to the invention contain as copolymerized monomer (A) a monoethylenically unsaturated monocarboxylic acid or dicarboxylic acid or a mixture of these acids.
  • the acids can be used in the form of their water-soluble salts, in particular the alkali metal salts, such as potassium and especially sodium salts, or ammonium salts, the dicarboxylic acids can also be wholly or partially in anhydride form. Of course, acid mixtures can also be used.
  • the monomers (A) preferably contain 3 to 10 carbon atoms.
  • Suitable monomers (A) are: acrylic acid, methacrylic acid, crotonic acid, vinylacetic acid, maleic acid, maleic anhydride, fumaric acid, citraconic acid, citraconic anhydride and itaconic acid.
  • Particularly preferred monomers (A) are acrylic acid, methacrylic acid and maleic acid (anhydride), with maleic acid (anhydride) being very particularly preferred.

  • suitable monomers (B) are: 1-butene, isobutene, 1-pentene, 1-hexene, diisobutene (2-methyl-4,4-dimethyl-1-pentene), 1-decene, 1-dodecene, 1-tetradecene, 1-hexadecene, C 18 -C 24 - ⁇ -olefins such as 1-octadecene, 1-eicosene, 1-docoses and 1-tetracoses, C 20 -C 24 - ⁇ -olefin mixtures, 1-hexacoses, polyisobutenes with an average of 12 to 100 carbon atoms and styrene.
  • isobutene, diisobutene and styrene are suitable as monoolefins (B1).
  • Particularly suitable monoolefins (B2) are 1-dodecene, C 18 -C 24 - ⁇ -olefins, C 20 -C 24 - ⁇ -olefin mixtures and polyisobutenes having an average of 12 to 100 carbon atoms.
  • the copolymers used according to the invention contain from 20 to 80% by weight, preferably from 30 to 70% by weight, of the monomer (B).
  • Very particularly preferred copolymers used according to the invention are by free-radical copolymerization of (A) 30 to 70 wt .-% maleic acid (anhydride), (B1) 20 to 40 wt .-% isobutene and (B2) 5 to 20 wt .-% of a C. 18 -C 24 - ⁇ -olefins available.
  • the copolymers used according to the invention have an average molecular weight M w of from 1,000 to 200,000 g / mol, preferably from 2,000 to 50,000 g / mol (determined by gel permeation chromatography at room temperature with aqueous eluent).
  • K values are accordingly from 10 to 150, preferably from 15 to 60 (measured at pH 7 in 1% strength by weight aqueous solution at 25 ° C.) H. Fikentscher, Cellulose Chemistry, Vol. 13, pp. 58-64 and 71-74 (1932 )).
  • copolymers used according to the invention can be prepared by known processes.
  • aqueous polymer solutions or dispersions which have a solids content of from 10 to 70% by weight, preferably from 25 to 60% by weight.
  • the viscosity of aqueous Waschschslurries, in particular of the slurries, which are dried to produce granular or powdered detergent compositions effectively lower, so that even highly concentrated slurries can be handled easily.
  • the slurry concentrations can always be ⁇ 50% by weight, preferably ⁇ 60% by weight, based on the anhydrous detergent components.
  • copolymers used according to the invention additionally bring about stabilization and homogenization of the slurries and prevent separations.
  • the anionic surfactants are preferably added to the detergent in the form of salts.
  • Suitable salts are e.g. Alkali metal salts such as sodium, potassium and lithium salts, and ammonium salts such as hydroxyethylammonium, di (hydroxyethyl) ammonium and tri (hydroxyethyl) ammonium salts.

  • Suitable color transfer inhibitors are, for example, homo-, co- and graft polymers of 1-vinylpyrrolidone, 1-vinylimidazole or 4-vinylpyridine-N-oxide. Homo- and copolymers of 4-vinylpyridine reacted with chloroacetic acid are also suitable as color transfer inhibitors.
  • the viscosity-lowering effect of the copolymer P was investigated in two detergent slurries.
  • the copolymer P was a copolymer of maleic anhydride, isobutene and 1-octadecene in a weight ratio of 65: 26: 9, which had an average molecular weight M w of 3000 g / mol and a K value of 24 (measured at Value 7 in 1% strength by weight aqueous solution at 25 ° C.).
  • the copolymer was used in the form of a 40 wt .-% aqueous solution.

  • Two different detergent slurries were prepared with stirring in a 500 ml heatable double-walled stainless steel vessel.
  • the liquid components were first heated to 50 ° C. with stirring for 10 minutes.
  • the stirrer used had a torque absorption.
  • the previously mixed solid components were then uniformly metered in over 4 minutes, with the slurry being further stirred at 150 rpm. After completion of the addition, the slurry was stirred at a constant speed while determining the torque.
  • the torque reflects the force needed to stir the slurry at a constant speed of rotation.
  • Table 1 lists the compositions of the detergent slurries. The amounts mentioned here refer to feedstocks in anhydrous form, i. without water or water of crystallization contained in the total water content.
  • Table 2 summarizes the torques obtained after each 30 minutes. For comparison, the results obtained without polymer addition are included.
