Abstract

Abstract The invention relates to an apparatus and process for producing striated soap bars using a high intensity mixer extruder. A soap mass is levigated and homogenized in a high intensity mixer barrel and forced into a dye injection assembly wherein dye is injected into the soap mass. The soap mass with the injected dye is then forced through conically tapered nozzles to form a striated soap bar.
