Definitions

  • the present invention relates to storage-stable detergents which, in addition to at least diperoxydodecanedioic acid or its salts, contain at least one specific optical brightener of the bis-benzofuranyl type, and to the production and use thereof for washing textiles.
  • M in formula (I) is, for example, alkaline earth metal such as magnesium or calcium, but preferably alkali metal such as lithium, sodium, potassium and optionally substituted ammonium such as ammonium, mono-, di- or triethanol-ammonium, mono-, di- or tripropanol -ammonium or tri- or tetramethyl-ammonium.
  • alkaline earth metal such as magnesium or calcium
  • alkali metal such as lithium, sodium, potassium
  • ammonium such as ammonium, mono-, di- or triethanol-ammonium, mono-, di- or tripropanol -ammonium or tri- or tetramethyl-ammonium.
  • the detergents contain brighteners of the formula
  • These optical brighteners of the formula I and II are known and can be prepared by known methods (DE-OS-2 238 734).
  • the peracids or their salts are organic or inorganic compounds which have been described in the literature or are on the market and which preferably bleach textiles even at temperatures from 20 ° C.
  • Diperoxydodecanedioic acid (DPDDA) is necessary as an organic peracid.
  • the amount of organic peracid to be used is preferably 0.5% to 10%, in particular 1% to 5%. But it can also be very effective, inorganic peracids such as persulfate and / or percarbonate are used.
  • the amount of inorganic peracids is preferably 1% to 20%, in particular 10% to 20%, based on the total weight of the detergent and, if appropriate, and advantageously in combination with small amounts of catalytic bivalent metal salts, as described in US Pat. No. 4,655,782 and U.S. 4,655,953.
  • Metal salts of copper and / or manganese are preferably used.
  • the peracids are mainly added to the detergent by mixing the components e.g. with the help of screw dosing systems and / or fluidized bed mixers.
  • the detergents are dry detergents of conventional compositions.
  • they contain, for example, anionic, nonionic, amphoteric and / or cationic surfactants, builders such as e.g. Pentasodium tripolyphosphate or substitute products such as phosphonates, polycarboxylates, acrylic-maleic copolymers, zeolites, nitrilotriacetate, ethylenediaminotetraacetic acid, soil suspending agents such as e.g. Sodium carboxymethyl cellulose, salts for adjusting the pH such as e.g.
  • Alkali or alkaline earth silicates foam regulators such as Soap
  • salts to adjust the spray drying and granulate properties such as Sodium sulfate, perfumes, and optionally antistatic and softening agents, enzymes, photobleaches, pigments and / or shading agents.
  • these components should be stable with respect to the bleaching system used.
  • a granulate A is produced by drying and granulating a slurry consisting of approx. 1 part water and 1 part detergent of the following composition: 84 g linear dodecylbenzenesulfonate 31 g tallow alcohol tetradecane ethylene glycol ether (14 AeO) 37 g Na soap (mainly from behenic acid and C14-C20) 458 g Na tripolyphosphate 79 g Na silicate 20g magnesium silicate 12 g carboxymethyl cellulose 2 g ethylenediamine tetraacetate 222 g Na sulfate 1 g optical brightener (FWA) according to the formula (I) - (II).
  • FWA optical brightener
  • the peracid B (15 g DPDDA) is mixed homogeneously into 500 g of this granulate A, which has a residual moisture of ⁇ 5% after drying.
  • the FWA determination mentioned above is carried out as follows: The washing powder is homogenized well by grinding and 1 g of it is mixed with 200 ml Solvent consisting of 9 parts of dimethyl sulfoxide and 1 part of water is added, and the mixture is stirred at room temperature for 30 minutes. Then it is centrifuged for 30 minutes. A sample of the clear solution thus obtained is transferred with a pipette into a 1 cm quartz cuvette and its absorbance in the UV range is measured at the absorption maximum against a standard solution of the respective FWA. The absorbance is proportional to the FWA concentration. The reproducibility of the results is approx. ⁇ 1% if the test conditions are observed exactly the same.
  • Example According to the conditions described above, the percentage FWA loss is determined. Storage is in a closed package, at 20 to 25 ° C. After 6 months, the FWA loss is:
