A process for producing solid detergent granular materials is presented involving (a) forming an aqueous surfactant paste of an anionic surfactant, an amphoteric surfactant or mixtures thereof, and (b) drying and granulating the aqueous paste in a horizontal thin-layer evaporator or dryer having rotating fittings, wherein the drying is carried out at a temperature of 120&deg; C. to 130&deg; C. The process produces granules having a bulk density greater than 600 grams/liter and a uniform particle size distribution.

Process for preparing raw materials for washing agents

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 fatty ketones

A process for the production of solid or paste-form products by fast reactions is carried out stoichiometrically wherein a gaseous medium is introduced into each of the reactants to be reacted with one another, the reactant streams formed are combined and are subsequently forced through a spray unit in a weight ratio of gaseous medium to product stream of from 0.04 to 0.3 (kg/kg) and at a rate of 0.1 to 15 m/second, as calculated from the gas-free reactant streams and based on the free cross-section of the spray unit. The products obtained are free from readily volatile constituents.

Process for the production of solid or paste-form products

Alkaline dishwashing machine detergent compositions containing an active chlorine composition and a foam inhibiting amount of a ketone containing at least 25 carbon atoms. A process for their preparation wherein the ketone is introduced into the composition as a dispersion in a liquid.
