Abstract
Abstract A process for making multicolored soap bars wherein a coloring agent is dispersed in a meltable solid vehicle and introduced into a base soap material as a liquid colored material before the base soap material is extruded in the form of a continuous log which is subsequently cut and pressed to form a multicolored soap bar. The meltable solid material solidifies upon contact with the base soap material to form variegated, striated or marbleized colored regions in the final bar.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
133 words
A method for producing multicolored soap bars comprising the steps of, supplying to the vacuum chamber of a double barrel plodder which comprises upper and lower barrels separated by a vacuum chamber, a liquid colored material including a meltable solid vehicle in a melted state selected from wax and wax-like materials having a melting point above about 100° F and a water soluble dye, supplying a base soap material to said plodder, combining said colored material with said base soap material such that said colored material solidifies when in contact with said base soap material, in the lower barrel of said double barrel plodder to form a multicolored soap mass, extruding said multicolored soap mass to form a multicolored billet, subdividing said billet into bars and pressing said bars to a desired shape.
