Abstract:
1. An extruded and stamped personal washing bar comprising an artisan crafted appearance having top and bottom stamped faces bounded by a parting line or edge band and a horizontal plane intersecting the parting line or edge band, said bar further comprising an outer surfactant phase and an inner vein comprising a thermoplastic mass wherein the outer surfactant phase and inner vein are thermoplastic within the temperature range of 30° C. to 50° C., wherein said inner vein is located between the top and bottom stamped faces of the bar and wherein a projection of the inner vein onto the horizontal plane intersecting the parting line or edge band has a maximum width that is at least 20% of a maximum width of the bar in said horizontal plane; wherein the outer surfactant phase comprises 25-95% surfactant and is an extruded phase: wherein the inner vein has at least some difference in chemical composition from the outer surfactant phase; and wherein the thermoplastic mass comprising the inner vein has a penetrometer hardness no greater than the penetrometer hardness of the mass comprising the outer surfactant phase when measured by the Cylinder Impaction Test carried out at a temperature in the range from about 35° C. to about 45° C.
