Abstract: The invention relates to encapsulated bleaching agent particles. Said particles consist of a core that contains a bleaching-agent active ingredient and a coating of water-soluble material that at least partially surrounds said core, the core containing peroxocarboxylic acid and the coating material containing polyvinyl alcohol. The particles can be produced by introducing a particulate peroxocarboxylic acid into a fluidized bed, by spraying an aqueous solution containing polyvinyl alcohol onto said bed and by subsequent drying or spray drying.

Abstract: Surfactant granulates containing 10 to 90 wt. % amine oxide, 10 to 90 wt. % carrier material and 0 to 50 wt. % binder can be manufactured by fluidized bed granulation and employed for upgrading a washing detergent or cleaning agent composition. The upgraded washing detergent or cleaning agent composition is characterized inter alia by an improved performance for the removal of fat-containing stains.

Abstract: The present invention relates to methods for producing bleach-activator-containing granules from a water-containing bleach activator preparation form by granulation and simultaneous drying in a fluidized-bed and subsequent consolidation of the primary granules by treatment with an aqueous polymer and/or phosphonate solution, in a fluidized bed.

Abstract: The invention relates to a method of producing soluble polymer granules which are suitable for use in washing and/or cleaning surfactants. According to said method, an aqueous preparation of the polymer which contains at least 30% by weight polymer, optionally in admixture with other washing and/or cleaning surfactant ingredients, is granulated and at the same time dried batchwise or continuously, preferably continuously, in a circular fluidized bed. In said fluidized bed, an eddy flow about the vertical axis of the apparatus is produced above the ground of the fluidized bed by means of an air inlet. The invention also relates to soluble, spherical polymer granules with a polymer content of 50 to 95% by weight and to washing or cleaning surfactants containing the inventive granules.

Abstract: A process for making substantially odorless granules of alkyl sulfates corresponding to formula (I): R-O-SO3X (I) wherein R is an alkyl group containing from 6 to 18 carbon atoms, and X is selected from the group consisting of an alkali metal, an alkaline earth metal, ammonium, an alkyl ammonium, and alkanolammonium, and a glucammonium ion, the process involving: (a) providing a water-containing paste of alkyl sulfates having a content of unsulfonated components of greater than 0.3% by weight; and (b) simultaneously granulating and drying, in a fluidized bed, the water-containing paste of alkyl sulfates to form substantially odorless granules of alkyl sulfates, and wherein the substantially odorles granules thus formed have less than 0.2% by weight, based on the weight of active substance, of unsulfonated components present therein.

Abstract: The invention relates to a process for the production of sugar surfactant granules in which water-containing sugar surfactant pastes are subjected to granulation in the presence of selected silicon compounds. In the production of such granules, caking problems are frequently encountered in the production units. A process for the production of sugar surfactant granules in which such problems are avoided has now been found. In this process, water-containing pastes of a) alkyl and/or alkenyl oligoglycosides and/or b) fatty acid-N-alkyl polyhydroxyalkyl amides are subjected to granulation in the presence of zeolites and/or waterglasses and optionally dried in a following process step, the granules being powdered with dusts during granulation.

Abstract: The problem addressed by the invention was to provide granules which would have a high content of liquid nonionic surfactants, more particularly above 20% by weight, but which would have little need for a water-insoluble carrier material and would be eminently suitable for incorporation in detergents. It has been found that granules of nonionic surfactants liquid at room temperature which contain a solidified polymer melt as carrier material and less than 10% by weight of inorganic carrier satisfy these requirements.

Abstract: The problem addressed by the invention was to provide a process for the production of organic granules which would give granules with a minimal dust content. It was found that this problem could be solved by a process for the production of granules in which organic compounds are introduced in the form of a melt into a fluidized bed which has a temperature below the softening temperature of the compounds to be granulated, granulated and optionally dried and in that the granules are discharged from the fluidized bed via a grading stage.

Abstract: The proposal is for unsaturated fatty substances with improved cold behavior obtained by (a) transesterifying a new low stearic (LS) sunflower oil with an oleic acid content of over 85 wt. % and a stearic acid content of under 3 wt. %, and (b) hydrogenating the resultant methyl esters in the prior art manner into the corresponding unsaturated fatty alcohols in the iodine number range from 90 to 100. The fatty substances are also distinguished by improved color and odor and are suitable for making fatty chemical products, e.g. alkoxylates, ether sulphates, sulphates and esters.
