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 stilbene type, and to their use 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.
  • optical brighteners of the formulas I to V are known and can be prepared by known methods.
  • the peracids or their salts are organic or inorganic compounds described in the literature or on the market, which preferably bleach textiles even at temperatures from 20 ° C.
  • Diperoxydodecanedioic acid (DPDDA) can be used as the organic peracid.
  • the amount of organic peracid to be used is preferably 0.5% to 10%, in particular 1% to 5%.
  • very effective inorganic peracids such as persulfate and / or percarbonate can also be used.
  • the amount of these inorganic peracids is preferably 1% to 20%, in particular 10% to 20%, based on the total detergent weight. If appropriate and advantageously, they are used in combination with small amounts of catalytically active bivalent metal salts, as are described in US Pat. Nos. 4,655,782 and 4,655,953.
  • Metal salts of copper and / or manganese are preferably used.
  • the peracids are added to the detergent by dry mixing e.g. with the help of automatic 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, for example, pentasodium tripolyphosphate or substitute products such as phosphonates, polycarboxylates, acrylic-maleic copolymers, zeolites, nitrilotriacetate, ethylenediaminotetraacetate , Dirt suspending agents such as sodium carboxymethyl cellulose, salts for adjusting the pH such as alkali or alkaline earth silicates, foam regulators such as soap, salts for adjusting the spray drying and granulate properties such as sodium sulfate, perfumes, and optionally antistatic and plasticizers, enzymes, photobleaches, pigments and / or shading agents.
  • these components should be stable with respect to the bleaching system used.
  • 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 of solvent consisting of 9 parts of dimethyl sulfoxide and 1 part of water and 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:
