A continuous, high speed process for making translucent soap bars which, optionally are provided with a striated pattern. The process uses a mixture of tallow and coconut fatty acids saponified with a mixture of sodium hydroxide and potassium hydroxide. To the neat soap is added a superfatting agent and glycerin and the resulting neat soap is dried to a moisture level of from about 14% to about 18%. The dried soap is thereafter subject to amalgamation where a slurry containing additional glycerin and a polyethylene glycol of molecular weight of about 600 is added to and mixed with said soap. Following amalgamation, the soap is refined and thereafter compacted and extruded into a continuous log which may be cut and stamped into bars. A striated pattern may be incorporated into the translucent bars by adding mica platelets to the slurry at the amalgamation stage and conducting the compaction and extrusion of said soap in an extrusion plodder provided with a compaction plate, such plate having a series of openings through which the soap is forced resulting in soap bars having a unique striated pattern.
In a process for the production of translucent soap wherein a blend of tallow fat and coconut oil or other fats and oils useful in the production of soap or the corresponding fatty acids derived therefrom are saponified or neutralized, with the resulting neat soap being dried, amalgamated, refined and formed in bars, the improvement comprising:
A process for the production of translucent bar soap having a striated pattern comprising saponifying a blend of tallow and coconut fatty acids with an alkali mixture of sodium hydroxide and potassium hydroxide, adding from about 0.8 to about 2.1% glycerin and from about 1.2 to about 2.0% superfatting agent to the resulting neat soap, the foregoing percentages being based on the weight of the neat soap, drying said neat soap to a moisture level of from about 14% to about 18%, subjecting the dried soap to amalgamation wherein a slurry containing polyethylene glycol with an average molecular weight of 600, additional glycerin and a planar reflective material are added to and mixed with said soap, the amount of said polyethylene glycol added to said soap being from about 2.5 to about 4.5% by weight of said soap and the amount of glycerin so added being at least about 0.5% by weight of said soap with the total amount of glycerin in said soap not exceeding 3.5% by weight of said soap, subjecting said soap to refining using a screen having openings no greater than about 0.8 mm., and thereafter compacting and extruding said soap in an extrusion plodder having an extrusion worm mounted to a worm support having openings therein, and a compaction plate mounted adjacent to said support, said compaction plate being provided with a series of openings through which said soap is forced, and wherein the ratio of the total open area of said worm support to the total area of the openings in said compaction plate is from 2:1 to about 3:1.
