  • Patent number: 6852260
    Abstract: A process for preparing a cleansing bar having well-defined platelet striations therein which comprises extruding a cleansing bar composition having platelets therein to form a cleansing bar using an extruder having a perforated barrier across the cross section of the extruder, wherein the perforated barrier is located at a sufficient distance downstream from the spider to allow well-defined platelet striations to be observed in the finished cleansing bar with the human eye. The perforated barrier is located at a distance from the spider equal to at least about 60%, preferably at least about 70%, of the distance from the spider to the extruder cone outlet of the extruder. Generally, a standard extruder cone length from spider to cone outlet is about 483 mm to about 560 mm.
