A bar soap recycling device including an enclosure assembly, a tray assembly, an electrical assembly, and a soap assembly is disclosed. These assemblies in conjunction with one another provide a simple solution to recycling used bars of soap. Leftover chips, slivers, or pieces of used soap bars are placed within a mold of the tray assembly. The tray assembly is placed within an enclosure that includes an integrated heating element. The heating element warms the heat conducting mold to the point of melting the used soap bars. A timer determines when the soap bars have had enough time to melt into the shape of the mold. A cooling element in the form of a fan then cools the mold and soap contained therein to resolidify the used bars of soap into a single bar. The resolidified bar of soap is then removed from the mold and ready to be used.

Provided is a method for productively producing a liquid or a paste soap composition which, even at low temperatures, maintains a liquid or paste state for a long time without separating, is gentle on the skin and eyes, and has high foaming power and good cleaning power. In this production method for a soap composition containing a sodium of a higher fatty acid and a potassium of a higher fatty acid, a liquid soap composition is prepared by: heating, to at least 80? C., and melting a mixed saturated fatty acid which is composed of 12- to 18-carbon saturated fatty acids containing 85 to 100 mol % of a 12- and a 14-carbon saturated fatty acid and does not contain an 8- to 10-carbon saturated fatty acid; then adding a cooling liquid composed of glycerin and water to the mixed saturated fatty acid all at once, cooling the mixture to a temperature at least 20? C. lower than the heated temperature, and then heating the mixture again and holding the mixture at a temperature between 40 and 55? C.; adding a mixed alkaline aqueous solution all at once to the mixed fatty acid-containing liquid that has been heated and held at said temperature, said mixed alkaline aqueous solution being obtained by mixing potassium hydroxide and/or potassium carbonate and sodium hydroxide and/or sodium carbonate in a molar ratio in the range from 90/10 to 30/70; and, while agitating, heating the mixture and then holding the mixture at a temperature between 80 and 95? C. in order to neutralize the mixture.
