Definitions

  • extrusions / pressings can also be carried out in low-pressure extruders, in the Kahl press (from Amandus Kahl) or in the Bepex extruder.
  • the temperature control in the transition region of the screw, the pre-distributor and the nozzle plate is preferably designed such that the melting temperature of the binder or the upper limit of the melting range of the binder is at least reached, but preferably exceeded.
  • the duration of the temperature influence in the compression range of the extrusion is preferably less than 2 minutes and in particular in a range between 30 seconds and 1 minute.
  • fine-crystalline, synthetic and bound water-containing zeolite such as zeolite NaA in detergent quality is used as the solid builder.
  • zeolite NaX and mixtures of NaA and NaX are also suitable.
  • the zeolite can be used as a spray-dried powder or as an undried stabilized suspension that is still moist from its production.
  • the zeolite can contain minor additions of nonionic surfactants as stabilizers, for example 1 to 3% by weight, based on zeolite, of ethoxylated C 12 -C 18 fatty alcohols with 2 to 5 ethylene oxide groups or ethoxylated isotridecanols.
  • agents contain up to 40% by weight of zeolite and in particular up to 35% by weight of zeolite, in each case based on the anhydrous active substance.
  • Other suitable ingredients of the agents are water-soluble amorphous silicates; they are preferably used in combination with zeolite and / or crystalline layered silicates.
  • Particularly preferred are agents which contain, above all, sodium silicate with a molar ratio (module) Na 2 O: SiO 2 of 1: 1 to 1: 4.5, preferably of 1: 2 to 1: 3.5.
  • the content of amorphous sodium silicates in the agents is preferably up to 15% by weight and preferably between 2 and 8% by weight.
  • small amounts of iron can be incorporated into the crystal lattice of the layered silicate according to the above formulas.
  • Suitable polymeric polycarboxylates are, for example, the sodium salts of polyacrylic acid or polymethacrylic acid, for example those with a relative molecular weight of 800 to 150,000 (based on acid).
  • Suitable copolymeric polycarboxylates are, in particular, those of acrylic acid with methacrylic acid and of acrylic acid or methacrylic acid with maleic acid. Copolymers of acrylic acid with maleic acid which contain 50 to 90% by weight of acrylic acid and 50 to 10% by weight of maleic acid have proven to be particularly suitable.
  • Their relative molecular weight, based on free acids is generally 5,000 to 200,000, preferably 10,000 to 120,000 and in particular 50,000 to 100,000. The use of polymeric polycarboxylates is not absolutely necessary.
  • sodium perborate tetrahydrate and sodium perborate monohydrate are of particular importance.
  • Other bleaching agents are, for example, peroxy carbonate, citrate perhydrates and salts of peracids, such as perbenzoates, peroxyphthalates or diperoxydodecanedioic acid. They are usually used in amounts of 8 to 25% by weight.
  • the use of sodium perborate monohydrate in amounts of 10 to 20% by weight and in particular 10 to 15% by weight is preferred. Due to its ability to bind free water with the formation of the tetrahydrate, it contributes to increasing the stability of the agent.
  • cellulose ethers such as carboxymethyl cellulose, methyl cellulose, hydroxyalkyl cellulose and mixed ethers, such as methyl hydroxyethyl cellulose, methyl hydroxypropyl cellulose, methyl carboxymethyl cellulose and mixtures thereof, and also polyvinylpyrrolidone, for example in amounts of 0.1 to 5% by weight, based on the composition.
  • the agents can contain derivatives of diaminostilbenedisulfonic acid or their alkali metal salts as optical brighteners .
  • Suitable are, for example, salts of 4,4'-bis (2-anilino-4-morpholino-1,3,5-triazinyl-6-amino) stilbene-2,2'-disulfonic acid or compounds of similar structure which instead of the morpholino Group carry a diethanolamino group, a methylamino group, anilino group or a 2-methoxyethylamino group.
  • Brighteners of the substituted diphenylstyryl type may also be present; e.g.
  • Uniformly white granules are obtained if, in addition to the usual brighteners, the agents are also present in customary amounts, for example between 0.1 and 0.5% by weight, preferably between 0.1 and 0.3% by weight, even in small amounts, for example Contain 10 -6 to 10 -3 wt .-%, preferably by 10 -5 wt .-%, of a blue dye.
  • a particularly preferred dye is Tinolux® (commercial product from Ciba-Geigy).
  • Soil repellants are substances which preferably contain ethylene terephthalate and / or polyethylene glycol terephthalate groups, the molar ratio of ethylene terephthalate to polyethylene glycol terephthalate being in the range from 50:50 to 90:10.
  • the molecular weight of the linking polyethylene glycol units is in particular in the range from 750 to 5000, ie the degree of ethoxylation of the polymers containing polyethylene glycol groups can be approximately 15 to 100.
  • the polymers are characterized by an average molecular weight of about 5000 to 200,000 and can have a block, but preferably a random structure.
  • Preferred polymers are those with molar ratios of ethylene terephthalate / polyethylene glycol terephthalate from about 65:35 to about 90:10, preferably from about 70:30 to 80:20.
  • polymers which have linking polyethylene glycol units with a molecular weight of 750 to 5000, preferably of 1000 to about 3000 and a molecular weight of the polymer from about 10,000 to about 50,000.
  • examples of commercially available polymers are the products Milease® T (ICI) or Repelotex® SRP 3 (Rhône-Poulenc).
  • the surfactant granules according to the invention were used in detergent tablets (formulations R1 to R3) to evaluate further application properties. These detergent tablets were compared with two examples of conventional detergent tablets (V1 and V2) in terms of their dissolution rate.
  • the preparations were pressed into tablets (weight 40 g, constant breaking hardness), packed airtight and then stored at 40 ° C. for 2 weeks.
  • the composition of the detergent tablets is shown in Table 2.
  • Formulations 1 and 3 are according to the invention, formulations V1 and V2 are used for comparison. To assess the dissolution behavior, the tablets were placed on a wire rack which was in water (0 ° d, 25 ° C). The tablets were completely surrounded by water. The disintegration time from immersion to complete disintegration was measured.
