Abstract

A process for the production of pourable and free-flowing granular detergent composition components containing an active substance at least partly liquid at room temperature and a fine-particle carrier material for that active substance wherein the carrier material has a mean particle size of 3 .mu.m to 0.5 mm by dropping the carrier material onto a rotating disk where it is radially accelerated by vanes arranged on the upper surface of said disk, and applying the liquid active substance to a stream of the carrier particles through an annular die formed by the outer edge of the rotating disk and a stator surrounding the disk.
