A process for preparing a detergent tablet having two or more regions comprises the steps of: (a) compressing a particulate composition comprising a detergent active component to form a compressed region of the tablet having a recess; (b) delivering to the recess a solution or melt comprising a mixture of at least one detergent active component and a fusible carrier material; and (c) solidifying the solution or melt.

Process for preparing detergent tablets having two or more regions

A method for providing multi-phase cleaning and washing agent shaped bodies is provided. A particulate premix ix compressed to form a shaped body containing a cavity and the cavity is filled with a molten suspension or emulsion of a matrix material with a melting point above 30% and at least one active material dispersed or suspended in the matrix material.

Method for producing multi-phase cleaning and washing agent shaped bodies

A solid-form dishwasher detergent that contains a builder combination of conventional phosphates and crystalline layer silicates. Despite its phosphate content, the detergent provides improved protection to sensitive tableware, more particularly glasses and decorated tableware, and improved cleaning performance.

Solid machine dishwashing detergent with phosphate and crystalline lamellar silicates

Laundry/dishwasher detergent portion

Shaped bodies containing builders, alkali sources, bleaching agents, enzymes and surfactants. Particularly high-performance detersive shaped bodies with high stability in storage, a good perfume profile and a defined solubility profile are obtained if more than 80% by weight of the total content of an active substance ( ) containing a constituent from the group of soil-release compounds is present in a region which makes up no more than 40% by volume of the shaped body.

Moulded body dishwasher detergents with soil release polymers

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.

Particulate acetonitrile derivatives as bleach activators in solid detergents

Bull's-eye tablets in which both the shaped body per se and the lands surrounding the bull's-eye are mechanically stable and even lend themselves to production in modern high-throughput tablet presses and in which the core placed in the larger shaped body is joined to the tablet in a stable manner and does not separate from the tablet matrix during production, packaging, transportation and handling can be obtained if the contour line of the core falls from the edge zone to the lowest point and climbs back to the edge zone.

Bull's-eye tablet

Complexes of the transition metals cobalt, iron, copper, and ruthenium having at least one and preferably at least five ammonia ligands are used to activate peroxygen compounds in aqueous cleaning solutions for hard surfaces. Compositions preferably contain 0.0025% to 0.25 by weight of the activating complex.

Cleaning agent with oligoammine activator complexes for peroxide compounds

Free-flowing, storage-stable homogeneous granules for protecting silver in machine dishwashing are obtained through a granular free-flowing component comprising an organic solid (I) from the group of alkylaminotriazoles and a constituent (II) selected from the group of alkali metal sulfates, the ratio of solid (I) to solid (II) being from 1:100 to 2:1, preferably from 1:70 to 3:2 and more preferably from 1:50 to 2:3 and the component having a particle size of 0.01 to 2 millimeters, preferably 0.05 to 1.8 millimeters and more preferably 0.1 to 1.6 millimeters.

Granular component containing alkylaminotriazole for use in machine dishwashing detergents

In machine dishwashing using low-alkaline detergents, the protection of silver was to be guaranteed. This was achieved by using 3-amino-5-alkyl-1,2,4-triazoles and salts thereof as silver protectors in machine dishwashing detergents. In addition, the dishwashing detergents may contain bleaching agents and builders.

Machine dishwashing detergents with silver protection

A phosphate-free mildly alkaline, dishwashing detergent composition containing:

Mildly alkaline dishwashing detergents

A process for inhibiting the corrosion of silver in a dishwashing detergent solution by adding to the solution an inorganic redox-active substance.

Corrosion inhibitors for silver

Enzyme preparation containing a silver corrosion inhibitor

Mixtures of nonionic ethers for use as rinse aids and/or cleaning hard
