Abstract

The process of producing a detergent in the form of portioned pressings by extrusion of a homogeneous premix containing a plasticizer or lubricant into strands through a perforated die under a pressure of from about 25 to about 200 bar and forming compacted granules thereof, and then pressing the compacted granules into portioned pressings such as tablets.
