A spray-dried amorphous alkali metal silicate compound which provides multiple-cycle washing performance. The silicate compound has a molar ratio of M O to SiO of 1:1.5 to 1:3.3 wherein M represents an alkali metal. The compound contains 0.5 to less than 30% by weight of anionic surfactant and has an absorption capacity for liquid components which is at least 20% higher than that of the same quantity of the alkali metal silicate compound which is free from anionic surfactant.

In the production of granules containing anionic surfactants and having a bulk density above 450 g/l by granulation of a surfactant preparation containing a non-surface-active liquid component, the water demand and hence the energy demand for evaporating the water can be reduced if the anionic surfactant in its acid form or a mixture containing one or more anionic surfactants in their acid form and an aqueous alkaline solution are separately treated with a gaseous medium, subsequently sprayed in substantially stoichiometric quantities into the granulation and drying zone either separately or together under a high propellant gas pressure and then granulated and, at the same time, dried, optionally with addition of one or more inorganic or organic solids.

Process for the production of surfactant-containing granules

The invention is a process for producing surfactant granules by mixing a water-containing surfactant with a solid to form granules, drying the granules and recycling the dried granules as a portion of the solid.

A magnetic deflection system for a high-power electron beam with an expanding cross-section area is used for melting or vaporizing metallic materials. Saddle coils are provided which open in a direction of expansion of the electron beam. With the aid of these saddle coils large deflection speeds of the electron beam are obtained with small imaging errors and large deflection angles.

The crude reaction products from the synthesis of alkyl glycosides are bleached by kneading the material substantially freed from the excess fatty alcohol and containing at most limited quantities of water with an oxidizing agent at such elevated temperatures that the reaction mixture lends itself to plastic processing. Temperatures of from about 50.degree. to 150.degree. C. are particularly suitable, although it is best to apply temperatures in the range from about 80.degree. to 100.degree. C. using aqueous hydrogen peroxide as the oxidizing agent. Bleaching is carried out under basic conditions, optionally by addition of an alkaline compound, such as for example 50% sodium hydroxide solution. The bleached product accumulates in the form of a solid. It is preferably mixed with typical compatible solids, more particularly typical constituents of detergents and cleaning preparations, to form a solid and preferably free-flowing alkyl glycoside compound.
