Abstract

The invention is a process for manufacturing granules of a washing or cleaning agent from an at least partly solid mixture of granules by admixing plasticizers or lubricants with the granules and passing the mixture through a mixing zone at an elevated temperature and pressure to form a plastic flowable material and passing the plastic flowable material through a plurality of orifices of small diameter and cutting the extruded material at predetermined lengths to form a particulate washing or cleaning agent.
