Abstract
Storage-stable homogeneous granules with detersive properties, which are obtained by agglomeration of one or more solids with one or more granulation liquids in a free-fall mixer divided into a mixing zone and a post-mixing zone and comprising a knock-down bar fixed to an end plate from which it crosses the entire mixing zone and optionally extends into the post-mixing zone and are optionally aftertreated, may be produced by in situ neutralization of anionic surfactant acids. The products thus produced show distinct performance advantages, the process also having cost-efficient aspects.
