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.

Phthalimidoperoxyhexanoic acid particles encapsulated in a water soluble material

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.

Method for producing bleach activator granules

A process of deodorizing water-containing solutions of cationic nitrile bleach activators by exposure to the action of a combination of a percarboxylic acid, a carboxylic acid and hydrogen peroxide.

Deodorization of cationic acetonitrile derivatives

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.

Polymer granules produced by fluidized bed granulation

A process for coating laundry detergent or cleaning product tablets that contain builder(s) and also, if desired, further laundry detergent and cleaning product ingredients, by transporting the tablets on a conveyor belt provided with a multiplicity of apertures and forcing coating material through the conveyor belt apertures from below with a force such that the coating material forced over the conveying plane forms a surge through which the tablets are transported.

Process for coating detergent tablets

A process for making substantially odorless granules of alkyl sulfates corresponding to formula (I): R-O-SO X (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.

Process of making alkyl sulfate granulates

A process for making detergent granules having a bulk density above 500 g/l involving: (a) providing a fluidized bed; (b) providing an apertured inflow base located below the fluidized bed for introducing fluidization gas into the fluidized bed; (c) providing a grid interposed between the fluidized bed and the apertured inflow base, the grid having a mesh size of less than 600 &mgr;m; (d) providing a surfactant preparation in liquid to paste form; and (e) introducing the surfactant preparation into the fluidized bed to form the detergent granules.

Method for producing tenside granulates with a higher bulk density

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.

Method of preparing saccharose surfactant granulates

Process for the production of detergent or cleaning tablets

The invention relates to a continuous process for the production of lower alkyl esters at temperatures of up to 100.degree. C. and under pressures of up to 10 bar by reaction of fatty acid triglycerides containing less than 1% free fatty acid with a lower alcohol in two stages in the presence of a homogeneous alkaline catalyst, the glycerol formed being removed after the first stage. To enable the process to be carried out with high yields and with lower maintenance, investment and energy costs than in the prior art, the reaction mixture is passed through a reactor and a following static separator only once in each stage, tube reactors are used as the reactors and the Reynolds number of the flow of the reaction mixture is greater than 2,300.
