Definitions

  • Bleach activators are important components in detergents, stain salts and Dishwashing detergents. They already enable a bleaching effect Temperatures below 60 ° C by using a source of hydrogen peroxide - mostly Perborates or percarbonates - with the release of an organic peroxy acid react.
  • Similar granules can be produced by spray-drying aqueous slurries containing the activator and the cellulose ether.
  • Granules consisting of bleach activator, cellulose ethers and additives of an organic C 3 -C 6 carbon or hydroxy carboxylic acid are described in WO 90/01 535 and WO 92/13 798. While in WO 90/01 535 the organic carboxylic acid is incorporated into the granulate core to accelerate its solubility, in WO 92/13 798 the carboxylic acid is applied to the finished granulate in an additional coating step.
  • the acidic protective coat is intended to prevent spotting of the bleaching agent and to protect the color of the fabric.
  • WO 94/03 395 claims for the same purpose the use of acidic polymer compounds with a water solubility> 5 g / l (at 20 ° C.) and molar masses of 1000 to 250,000.
  • Also known are granules of bleach activators in which mixtures of soaps and free fatty acids are used as granulation aids.
  • particles can also be produced in which a bleach activator which is solid per se is deposited in finely divided form on an inorganic carrier material.
  • the activator and carrier material are first mixed intimately and an organic solvent (ethanol or toluene) is added, whereby the activator goes into solution. Subsequent distillation of the solvent causes the activator to be deposited on the carrier in finely divided form.
  • the preferred particle size distribution of the particles according to the invention is between 60 and 250 ⁇ m.
  • the invention thus relates to bleach activator granules consisting of essentially from an ammonium nitrile and a layered silicate.
  • a mixing unit e.g. Ploughshare mixer
  • the mixture of ammonium nitrile and binder intimately mixed.
  • the mixture becomes larger particles pressed. Suitable for this include Roller compactors.
  • the compacts will then subjected to comminution (grinding) and to the desired Grain size crushed. Toothed pulley rollers and / or are suitable for this purpose Passiersrebe.
  • ammonium nitriles trimethylammonium acetonitrile toluenesulfonate (1) and N-cyanomethyl-N-methylpiperazinium toluenesulfonate (2) and TAED (3) were tested in non-granulated form: 2.7 g bleach activator powder 1 3.1 g bleach activator powder 2 2.3 g bleach activator TAED powder
