Article for use in a dishwashing machine, which comprises a water-soluble glass or ceramic composition effective to reduce corrosion of glassware and at least one surfactant containing composition, wherein the amount of the glass or ceramic composition is within the range of 5 to 95 wt. % and the amount of the surfactant is in the range of 5 to 95 wt. %, both percentages based on the weight of the article.

A process for the production of detergent particles comprises feeding an acid precursor of an anionic surfactant, a neutralizing agent and aluminosilicate detergency builder into a horizontal thin-film evaporator/drier. The evaporator/drier comprises a mixing region, a drying region and a cooling region. Neutralization of the acid precursor is effected, together with granulation, drying and cooling, to form the detergent particles. At least some of the aluminosilicate builder is fed into the thi...

In process for producing detergent particles, an acid precursor of an anionic surfactant and a neutralizing agent are fed into a horizontal thin-film evaporator/drier where they are neutralized, granulated and dried. The neutralizing agent is present in an amount equal to or in excess that required for stoichiometric neutralization and has a D50 mean particle size of less than 40 .mu.m.

A process for the preparation of a homogeneous, storage-stable detergent for dishwashing machines in the form of fused blocks containing alkali metal hydroxide, alkali metal silicate, water, penta-alkali metal triphosphate, active chlorine donor, and organic complexing agent; comprising preparing a melt of alkali metal silicate, alkali metal hydroxide and water, maintaining the melt at a temperature of about 50.degree. C. to about 75.degree. C., adding to the melt an active chlorine donor and an...

The invention relates to particulate solids comprising more than 90% by weight of natural or synthetic surface-active compounds for which a) the mean particle size of the particulate solid particles is 10 to 3000 .mu.m, b) the surface-active compounds are solid at room temperature, and c) the surface-active compounds have a melting point of from 25 to 250.degree. C.

A process for making substantially water- and dust-free anionic surfactant granules of high bulk density involving: (a) providing a starting material containing a water-containing paste of a monoglyceride (ether) sulfate having a solids content of at least 20% by weight, based on the weight of the paste; (b) providing a horizontally mounted thin-layer evaporator with rotating internals; (c) providing a negative temperature gradient within the evaporator; (d) passing air into the evaporator in co...

A solid functional material comprises a functional agent such as a cleaning composition, a sanitizing agent, where a rinse agent, etc. in a solid block format. The solid block is formed by a binding agent that forms the active ingredients into a solid block. The binding agent comprises a phosphonate or amino acetate sequestrant, a carbonate salt and water in an E-Form hydrate. These materials at a specific mole ratio form a novel binding agent that can form functional materials into a solid matr...
