The invention relates to an agglomerate containing at least one of the following water-soluble or water-dispersible materials as a bonding base polymer: carboxylized and/or alkoxylized starch, cellulose ether and fully synthetic vinyl polymers and/or polyacrylates. The agglomerate is characterized in that it contains a blasting agent which produces a high swelling pressure, but, advantageously, does not gel. The agglomerate can have a regular geometric form or not. Its weight should be between 0.5 and 500 g. The agglomerate is used in particular in the production of lump-free paste.

Agglomerates for the production of an aqueous binder system

A process for the production of pourable and free-flowing granular detergent composition components containing an active substance at least partly liquid at room temperature and a fine-particle carrier material for that active substance wherein the carrier material has a mean particle size of 3 &mgr;m to 0.5 mm by dropping the carrier material onto a rotating disk where it is radially accelerated by vanes arranged on the upper surface of said disk, and applying the liquid active substance to a stream of the carrier particles through an annular die formed by the outer edge of the rotating disk and a stator surrounding the disk.

The present invention relates to a granular adsorbent having a high uptake capacity for liquid ingredients of detergents and cleaning preparations, comprising

Granular adsorbent

A detergent having improved detergency particularly with respect to greasy soil comprising (a) a mixture of water-insoluble nonionic surfactants, (b) a water-soluble anionic surfactant of the sulfonate or sulfate type, (c) a detergent builder and (d) other standard detergent ingredients. The nonionic surfactant comprises a mixture of (i) an ethoxylated C.sub.16 -C.sub.18 alcohol with 4 to 6 glycolether groups, (ii) an ethoxylated C.sub.10 -C.sub.14 alcohol with 4 to 6 glycolether groups and (iii) an ethoxylated C.sub.10 -C.sub.18 alkylamine with 1 to 3 glycolether groups. The nonionic surfactant is adsorbed on a granular carrier material which is soluble or dispersible in water. The weight ratio of constituent (i) to constituent (ii) to constituent (iii) is within the range of 1:2(2-6):(0.8-2.5) and the weight ratio of the nonionic surfactant to the anionic surfactant is within the range of 4:1 to 4:3. The carrier material preferably comprises a spray-dried mixture of from 60 to 80% zeolite, from 3 to 20% of a copolymeric carboxylic acid, from 0.1 to 3% sodium silicate and water and may contain up to 40% by weight of nonionic surfactant. The carrier material which is impregnated with the nonionic surfactant is combined with other, optionally spray-dried powder constituents containing the other components to form a homogeneous powder mixture.

Granular detergent of improved detergency containing 2 ethoxylated

A free-flowing washing powder of low specific gravity (powder density 300 to 500 g/l) and containing large quantities of nonionic surfactants is produced by spray-drying an aqueous suspension containing on the spray-dried basis (A) from 15 to 30% by weight of nonionic tensides, (B) from 8 to 18% by weight of sodium silicate, (C) from 25 to 55% by weight of finely crystalline zeolite, (D) from 0 to 25% by weight of sodium tripolyphosphate, (E) no more than 3% by weight of soap and synthetic anionic tensides, and from 35 to 50% by weight of water. The suspension, which has a temperature of from 75.degree. C. to 90.degree. C., is sprayed through nozzles into a drying zone under a pressure of from 35 to 100 bar. The drying gas flowing in countercurrent has an entry temperature of from 160.degree. C. to 240.degree. C. and an exit temperature of from 80.degree. C. to 95.degree. C. The spray-dried product contains from 9 to 16% by weight of water which is removable at a drying temperature of 130.degree. C.

Process for the production of a spray-dried nonionic washing aid

Foam regulators particularly suitable for use in surfactant-containing compositions, comprising a mixture of paraffin hydrocarbons and hydrophobic silica, preferably admixed with a carrier.

Foam regulators containing paraffin hydrocarbons and hydrophobic silica

This invention relates to a granular, free-flowing detergent component which dissolves rapidly in water and which has a powder density of from 550 to 900 g/l, consisting of synthetic, essentially nonionic surfactants, inorganic supports, other organic washing aids, and water bound by adsorption and in hydrate form. The detergent component is produced by spray-drying, and more than 50% by weight thereof consists of droplet-like to rodlet-like particles having an average diameter of from about 0.02 to 1.5 mm, an average length of from about 0.1 to 5 mm, and a ratio of average diameter to average length of from about 1:1.2 to 1:10, optionally coated with a finely divided water-soluble or water-dispersible solid material as a fluidity improving agent.

Granular, free-flowing detergent component and method for its production

A spray-dried, high-sudsing detergent granulate is disclosed having a bulk density of not more than 450 gm/l and a high content of anionic tensides, which is characterized by a granule structure resistant to mechanical and climatic influences. The detergent granulate contains a tenside component of alkylbenzene sulfonates and, possibly, fatty alcohol sulfates, a builder component of sodium tripolyphosphate, finely crystalline sodium aluminosilicate (zeolite NaA) and sodium silicate. For the preparation, an aqueous slurry is sprayed in spray-drying equipment. The obtained spray-dried product has a porous granule structure with a mean granule size of 0.4 to 0.8 mm. The bulk density is preferably in the range from 250 to 400 gm/l.

High-sudsing, granular detergent composition with greater granulate

C.sub.8 -C.sub.40 Alcohols, or C.sub.8 -.sub.C 40 alcohol containing one or more hydroxyl groups and onto which up to 20 moles of ethylene oxide and/or propylene oxide can be added per mole of alcohol, when added to aqueous industrial anionic surfactant concentrates, particularly concentrates of .alpha.-sulfofatty acid esters containing at least 50% by weight of the sodium salt of .alpha.-sulfofatty acid ester, significantly improve the rheological behavior thereof. The alcohols are added in quantities of from about 1 to about 15% by weight, based on the quantity of surfactant, whereupon the viscosity of the surfactant concentrate becomes at most 10,000 mPas at 70.degree. C.
