Abstract: Methods for manufacturing surfactant granules, which methods comprise: (a) neutralizing an anionic surfactant acid with a solid neutralization agent, wherein the anionic surfactant acid has a water content of 5 to 24 wt %, and wherein the anionic surfactant acid and the solid neutralization agent are agglomerated in a free-fall mixer, to form surfactant granules having a bulk density of 300 to 800 g/l, are described.

Abstract: Processes which comprise: (a) blending a solid component and a liquid component in a mixer/granulator to form an intermediate granule mix; and (b) further treating the intermediate granule mix in a fluidized bed granulator to form granules; wherein a first portion of the liquid component is introduced into the mixer/granulator and a second portion of the liquid component is introduced into the fluidized bed granulator are disclosed. The solubility of granules prepared in accordance with the disclosed processes can be manipulated. Detergent and/or cleansing agents containing such granules and tablets incorporating such agents, as well as their use, are also described.

They can be used as bleaches or bleach component in, in particular, particle-shaped detergents and cleaners and for the production thereof.

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: 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.

Abstract: A process for making detergent granules having a bulk density of 300 to 700 g/l. A solid carrier containing neutralizing agent is mixed in a rotating mixer with a liquid binding agent containing surfactant acid to forma partially granulated premixture. The premixture is fluidized, sprayed with additional binder, and granulated in a fluidized bed reactor to form the detergent granules.

Abstract: A detergent or cleaner shaped body having a viscoelastic phase. The viscoelastic phase contains, based on its weight, 40 to 85% by weight of one or more alkylbenzenesulfonates and has a storage modulus of between 40,000 and 800,000 Pa.

Abstract: A process for making a detergent tablet by forming a disintegrating agent by compacting cellulose or a cellulose derivative, forming disintegrating agent particles comprising the disintegrating agent, dry mixing a washing- or cleaning-active substance and an amount of the disintegrating agent particles effective to rapidly dissolve or disperse the composition in water, and shaping the resulting mixture into a tablet. The disintegrating agent particles have a particle size distribution of less than 10% by weight smaller than about 0.2 mm particle size and no more than 1% by weight of dust-fine particles.

Abstract: Finely ground zeolithic alkali metal aluminum silicates having the general formula: xMe.sub.2 O.Al.sub.2 O.sub.3.ySiO.sub.2.zH.sub.2 O, are prepared by mixing both reaction components, alkali metal silicate and alkali metal aluminate, in the presence of a stoichiometrically excessive amount of alkali metal hydroxide. The thus obtained gel is matured, the reaction mixture is heated up to crystallisation temperature, then crystallised. During crystallisation, at least one of both reaction components is added to the reaction mixture.

Abstract: 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.
