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.

A particulate washing or cleaning composition containing (A) a phosphate-free water-soluble builder component and (B) alkali metal percarbonate particles having a coating containing alkali metal silicate.

Bleach-containing washing or cleaning agents containing a sulfate/silicate coated percarbonate

A textile-care composition that advantageously combines colour preservation with care of fibres and especially greying-inhibiting action was to be developed. That was achieved by means of a composition for textile care, comprising at least one cellulase and at least one colour-fixing polymer containing imidazolidine units.

Fabric-care agent

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.

A low-foam emulsifier system is presented containing (a) an ethoxylate/propoxylate of one or more C -C fatty alcohols, where the ethoxylate/propoxylate contains 2 to 6 ethylene oxide units and 4 to 8 propylene oxide units, with (b) a fatty alcohol propoxylate or distillation residue of fatty alcohol or fatty alcohol propoxylate, where the fatty alcohol contains 12 to 24 carbon atoms and up to three propylene oxide units. The weight ratio of (a) to (b) is from 1:0.3 to 0.3:1. The emulsifier system produces a low amount of foam, and is useful in industrial metal processing applications such as cleaning, corrosion protection or cooling lubricant emulsions.

The invention set out to improve the oxidizing and bleaching effect of inorganic peroxygen compounds in dishwashing, more particularly machine dishwashing, in terms of their storage stability. This was essentially achieved by using particulate compounds corresponding to formula R R R N CH CN X , in which R , R , and R independently of one another represent an alkyl, alkenyl or aryl group containing 1 to 18 carbon atoms, in addition to which the groups R and R may even be part of a heterocycle including the N atom and optionally other hetero atoms, and X is a charge-equalizing anion. Dishwashing detergents, more particularly machine dishwashing detergents, contain about 1% by weight to 10% by weight of this bleach-boosting agent.

A process for phosphating metal surfaces in which a nitrite- and nickel-free zinc-containing phosphating solution is applied to the metal surfaces which, if desired, are then rinsed and subsequently after-rinsed with an aqueous solution with a pH value of 3 to 7 which contains 0.001 to 10 g/l of one or more of the cations of Li, Cu and Ag.

Detergents containing enzymes and bleach activators

The invention relates to detergents characterized in that they contain &agr;-amylase from and protease from , optionally modified by genetic engineering, in addition to our usual ingredients compatible with said enzymes.

Detergents containing amylase and protease

An acidic aqueous phosphating solution is presented having 0.2 to 3 g/l of zinc ions, 3 to 50 g/l of phosphate ions expressed as PO , and 0.05 to 4 g/l of an organic N-oxide containing a saturated, unsaturated or aromatic 5- or 6-membered ring system, where the N atom of the N-oxide is part of said ring system, and where the ratio by weight of phosphate ions to zinc ions is from 3.7 to 30:1. The solution is free of hydroxylamine and useful in phosphating metal surfaces.

The storage stability of bleach-activating acetonitrile derivatives in solid detergent compositions was to be improved. This was essentially achieved by the use of compounded compounds corresponding to formula R,R,R,N,CH,CN X,, in which R,, R,and R,independently of one another represent an alkyl, alkenyl or aryl group containing 1 to 18 carbon atoms, in addition to which the groups R,and R,may even be part of a heterocycle including the N atom and optionally other hetero atoms, and X is a charge-equalizing anion. &ldquo;Compounds&rdquo; of this type are produced by drying in vacuo, for which purpose a suspension of the acetonitrile derivative and a solid carrier material is introduced into a mixer and the resulting mixture is dried with superheated vapor. Dishwashing detergents, more particularly machine dishwashing detergents, contain about 1% by weight to 10% by weight of this bleach boosting compound.
