Patent number: 4752408Abstract: 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.Type: GrantFiled: October 9, 1986Date of Patent: June 21, 1988Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Klaus Koester, Franz-Josef Carduck, Heinz-Manfred Wilsberg, Rolf Puchta

Patent number: 4726908Abstract: 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.Type: GrantFiled: February 11, 1986Date of Patent: February 23, 1988Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Hans Kruse, Franz-Josef Carduck, Jochen Jacobs, Klaus Koester, Rolf Puchta, Heinz-Manfred Wilsberg

Patent number: 4714479Abstract: Delicate fabrics of wool or silk are hand-washed or machine-washed using an aqueous detergent which is free from inorganic builder salts and optical brighteners and which shows a substantially neutral reaction, comprising (a) from 5 to 25% by weight of an alkyl glycol ether sulfate containing primary C.sub.12 -C.sub.18 -alkyl groups and from 1 to 3 ethylene glycol ether groups, (b) from 0.5 to 5% by weight of monoethanolamides of C.sub.12 -C.sub.18 -fatty acids, (c) from 0.1 to 1.0% by weight of an emulsified silicone defoamer, and water. In addition, the detergent may contain (d) up to 5% by weight of non-surface-active detergent additives, such as sequestrants, preservatives, dyes and perfumes.

Patent number: 4642197Abstract: 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.Type: GrantFiled: May 13, 1985Date of Patent: February 10, 1987Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Hans Kruse, Klaus Koester, Franz-Josef Carduck, Heinz-Manfred Wilsberg, Rolf Puchta
