PROCESS AND APPARATUS FOR PRODUCING A CLEANSING BAR

摘要

A process for preparing a cleansing bar having well defined platelet striations therein which comprises extruding a cleansing bar having platelet s therein using an extruder having a perforated barrier across the cross secti on of the extruder, the barrier a sufficient distance from the spider so that well-defined platelet striations are observed in the finished bar with the human eye. Generally the perforated barrier is located at least about 60% preferably at least about 70% from the spider, as measured from the spider t o the extruder cone outlet. Generally, a standard extruder cone length from spider to cone outlet is about 483mm to about 560mm.
