摘要:
The process of preparing granules of sodium perborate monohydrate having an increased density by dry-compacting a mixture of sodium perborate monohydrate and from about 0.2 to about 30% by weight of a compacting aid, based on the weight of the mixture. The compacting aid is selected from the group consisting of an alkali metal salt, alkaline earth metal salt, carbohydrate, anionic surfactant, and nonionic surfactant. After forming a compactate of the mixture, the compactate is size-reduced to obtain granules having the desired particle size.
摘要:
Solid fabric-care preparations showing a tendency towards troublesome interactions, or constituents thereof, are coated by application of dissolved or dispersed organic film-forming polymers soluble in alkaline medium. Suitable polymers contain in particular carboxyl groups and are preferably derived from vinyl esters. The carboxyl groups emanate from copolymerized carboxylic acids which make up from about 2 to 10 mole % of the copolymer. The copolymers are best prepared in the form of finely divided dispersions and optionally contain a protective colloid and/or an emulsifier.
摘要:
A washing additive consisting of a bag, filled with a detergent composition, of a polyvinyl-alcohol-based film readily soluble in borate-containing aqueous solutions. The detergent composition is a mixture of a nonionic surfactant, a quaternary ammonium compound containing a long-chain radical, which may be completely or partly replaced by a fatty amine ethoxylate or by a .beta.-aminoalkyl propionic acid derivative, an activator for per compound, an antigel agent, and a viscosity regulator, wherein the mixture has a viscosity of from 1000 to 100,000 mPas for a shear gradient of from 5 to 500 s.sup.-1.

摘要:
A cigarette paper pack for storing and supplying cigarette paper sheets for the self-rolling of cigarettes includes a container. The container comprises an insertion opening, the insertion opening comprising a latching protrusion, and at least one stack of cigarette paper sheets. An uppermost layer of the at least one stack of cigarette paper sheets extends through at least one removal opening assigned thereto in a wall. The wall is configured to form an upper side of the container during the use thereof. A recloseable cover is connected to the container. The reclosable cover comprises an insertion tab which comprises a latching opening. The reclosable covering is configured to be pivoted about a periphery so as to form a hinge axis. The insertion tab is configured to be inserted into the insertion opening. The latching opening and the latching protrusion are configured to form a latching device.
摘要:
For the production of solid, substantially anhydrous alkali metal salts of .alpha.-sulfofatty acid alkyl esters containing from 8 to 22 carbon atoms in the fatty acid chain and from 1 to 6 carbon atoms in the ester alkyl radical, solid or molten .alpha.-sulfofatty acid alkyl esters are simltaneously mixed with an aqueous solution of hydrogen peroxide or an H.sub.2 O.sub.2 -yielding compound and with solid alkali metal carbonate at a temperature of from 20.degree. to 80.degree. C. optionally in the presence of aqueous alkali metal hydroxide, the ratio by weight of ester of H.sub.2 O.sub.2 being from 1:0.01 to 1:0.06 and the molar ratio of ester to alkali metal carbonate being in the range of from 1:0.5 to 1:0.75, the foam formed through the release of CO.sub.2 is mechanically destroyed under a pressure of from 0.2 to 1.0 bar and at a temperature of from 50.degree. to 70.degree. C., and the product formed is residually degassed and residually dehydrated under a pressure of from 15 to 50 mbar and a temperature of from 50.degree. to 80.degree. C.

摘要:
A free-flowing granulate of a powder-form or fine-grained component and a liquid component; the granulate containing at least 20% by weight of the liquid component, is prepared by moving the powder-form or fine-grained component in a mixer-granulator, adding the liquid component while mixing until a moist granulate having a particle size of at most 1.5 mm is obtained, subsequently coarsening the granulate thus obtained with an increase in temperature to a particle size of from 0.4 to 4 mm and optionally coating this coarse granulate with another powder-form and/or fine-grained component at 60.degree. to 90.degree. C. The optionally coated granulate is converted by lowering the treatment temperature into a dry-looking, free-flowing, coarse-grained product, which if desired, may be coated with another powder-form and/or fine-grained material. Despite the high percentage of a liquid component, the granulate thus obtained appears as a dry granulate and is free-flowing.

A process for purification of an aromatic fraction containing acetylenes as impurities by selective hydrogenation of the acetylenes by means of a catalyst containing nickel or palladium at a temperature of not more than about 60° C. is described.
摘要:
A powdery activator for per compounds is granulated by, at the same time, mixing it together with nonionic surface-active compounds certain nitrogen-containing compounds and, optionally, the water-soluble salt of an alkane polyphosphonic acid. The granulate thus obtained is powdered with a powdery absorbent and the powdered granulate is sprayed with a liquid binder and dried to a water content of at most 6% by weight. After the addition of a tablet disintegrating agent, the dried granulate is formed by compression under special conditions into tablets having special properties. When added to a wash liquor containing a standard detergent containing a per compound, the tablets improve the removal of fatty/oily stains, pigment-containing soil and bleachable stains.
