Abstract
Production of laundry and detergent-active surfactant granulates comprises granulating a mixture containing anionic surfactant, which is prepared by partial to complete neutralisation of anionic surfactant(s) in their acid form with inorganic or organic neutralising medium in a mixer, in which the anionic surfactant mixture is added to a solid (or solid mixture) in the mixer. The solid is a spray-dried compound containing alkyl benzenesulphonate and/or fatty alcohol sulphate and optionally other solids normally used in laundry agents and detergents. The (partly) neutralised mixture containing anionic surfactant optionally at elevated temperature, is added to the solid (mixture) and granulation is regulated so that the total surfactant content of the dried granulate is > 40 wt.%. Also claimed are (i) a surfactant granulate with a bulk density > 700 g/l and (ii) laundry agents and detergents containing at least 50 wt.% surfactant granulate produced in this way.
