The invention relates to a pasty washing agent for use in commercial laundering which contains a non-ionic surfactant, an organic and/or inorganic builder, a bleaching agent based on peroxygen, and optionally contains other common constituents. The inventive pasty washing agent is characterized in that it contains 30 wt. % to 60 wt. % of non-ionic surfactant, 0.5 wt. % to 5 wt. % of a fatty acid and/or fatty acid alkaline-salt, 5 wt. % to 15 wt. % of citrate and/or citric acid and 15 wt. % to 35 wt. % of an inorganic peroxygen compound. In addition, the pasty washing agent does not contain alkali metasilicate nor a bleach activator. In addition to exhibiting a good cleaning efficiency, the inventive agent has a disinfecting action.

Pasty washing agent

Process for the handling of waste waters

A process for the preparation of a cation-exchanging alkali metal aluminosilicate granulate having a particle size of from 0.05 to 1 mm comprising (a) charging a finely-divided, crystalline water-containing alkali metal aluminosilicate powder having a calcium binding power of from 50 to 200 mg CaO/gm of anhydrous aluminosilicate and a particle size of less than 30.mu. into a conventional granulator, (b) adding thereto (i) m moles of SiO.sub.2 as an aqueous alkali metal silicate solution or an aqueous silicic acid sol, and (ii) n mols of Al.sub.2 O.sub.3 as an acidic hydrolyzing aluminum salt and/or alkali metal aluminate powder and/or an aqueous alkali metal aluminate solution, (c) mixing until the moisture is uniformly absorbed and a granulate with a particle size of 0.05 to 1 mm is formed, and (d) drying said granulate at 80.degree. to 150.degree. C.

Process for the preparation of alumino-silicate granulates

An improvement in the machine washing of solid soiled materials comprising withdrawing and recycling the wash liquor in contact with said solid soiled materials through a silicate cation exchange compound having some combined water and a particle size of at least 10.mu. of the formula:
