[0070] The present invention is further directed to a method of making a sodium and potassium soap sponge comprising i) heating a translucent soap comprising glycerinum, propranediol, sorbitol, an alkali, a foaming agent, 12 dodecanoic acid, stearic acid, CAB-35 (cocamidopropyl betaine), industrial white granulated sugar, edible alcohol, purified water, a fatty acid sodium salt and a fatty acid potassium salt until the soap is completely melted; ii) mixing an amount of milky white soap base in with the translucent soap and heating the combination until melted completely wherein the milky white soap base comprises glycerinum, propranediol, sorbitol, an alkali, a foaming agent, 12 dodecanoic acid, stearic acid, CAB-35 (cocamidopropyl betaine), industrial white granulated sugar, edible alcohol, purified water, a fatty acid sodium salt and a fatty acid potassium salt and titanium white pulp; and wherein the ratio of translucent soap to milky white soap base is about 1:0.45; iii) mixing in a foaming surfactant agent to the combination of translucent soap and milky white soap base, wherein the amount of foaming surfactant agent is 2% of the total mixture; iv) adding a coloring agent and/or a flavoring agent to the mixture and then further mixing; v) pouring the mixture into a mold; vi) placing a sponge into the mold containing the soap and allowing the soap to sink into the sponge; vii) cooling the molds containing the soap and sponge until the soap is solid and removing the sodium and potassium soap sponge from the mold.

[0071] The transparent soap is heated until melted. In certain embodiments, the heating is carried out in a microwave, with the soap being heated for about 8 minutes at a temperature of about 100 C.

[0072] After the transparent soap has been melted, the milky white soap base is mixed in. The combination of the transparent soap and the milky white soap base is then heated until the mixture is completely melted. In certain embodiments, the heating is carried out in a microwave for about 6 minutes at a temperature of about 97.3 C.

[0073] After the mixture of soaps is completely melted, a foaming surfactant agent is mixed in with the transparent and milky soaps. The mixture is heated after the foaming surfactant agent is added in. Preferably, the heating is by microwave for about 6 seconds at about 97 C.

[0074] In certain embodiments of the present invention, a coloring agent and/or fragrance are added to translucent soap/milky white soap base/foaming surfactant mixture. Preferred fragrances include sea & rose, forest, volcanic mud, bamboo carbon, green tea flavor.

[0075] The mixture is then poured into a mold. The molds used in the present invention can be of any size and shape desired and of a variety of materials known to those of skill in the art. For example, the molds can be made of silicone, ethylene vinyl acetate copolymer or polypropylene In preferred embodiments of the present invention, the molds are not completely filled with the mixture to allow room for the placement of the sponge in the mixture without overflow of the mixture.

[0076] In certain embodiments, the bottom of the mold is scraped as the mixture is poured in to avoid air bubbles. A sponge is then placed in the soap filled mold before the soap solidifies, with a portion of the sponge left out of the soap. The sponge can e.g. be a hydrophilic polyurethane sponge manufactured in the manner detailed below or in another suitable manner known to those of skill in the art. In most preferred embodiments, about 4 mm of the sponge is left out of the soap after solidity.

[0077] The molds containing the soap and sponge are then cooled until the soap is solid. In preferred embodiments, the molds can be placed in a refrigerator for cooling at 15 C. for 2 hours and until the soap is solid. In certain preferred embodiments, immediately after removing the mold from the refrigerator, the soap sponge is removed from the mold and wrapped with a plastic film to avoid deterioration.

[0078] The sponges used for the present invention can be standard sponges used with sponges. Alternatively, sponges can be specifically manufactured for the sodium and potassium soap sponge. For example a preferred sponge is made of hydrophilic polyurethane. The sponges are cut and shaped to fit the desired mold shapes and sizes. Preferably, the sponges are from 55 mm55 mm to 95 mm67 mm.

[0079] In certain embodiments, the molds are slightly bigger in dimension than the sponges. In certain preferred embodiments the molds range in size from about 60 mmabout 60 mm to about about 100 mmabout 72 mm.

Example 4: Production of Sodium and Potassium Soap Sponge

[0084] 1320 grams of the transparent soap from Example 1 are heated in a microwave for 8 minutes at a temperature of 100 C. so that the transparent soap is completely melted. 600 grams of the milky white soap base from Example 2 are then mixed in with melted transparent soap and the mixture is then heated in a microwave for about 6 minutes at a temperature of about 97.3 C. so that both the milky and transparent soaps are melted completely.

[0085] The mixture is then removed from the microwave and 39 grams of APG2000, a foaming surfactant agent is added to mixture of the transparent and milky soaps and then the mixture is heated in a microwave for about 6 seconds at about 97 C.

[0086] 39 grams of forest flavor are added to the mixture, after which 1.1 grams of CO15, a green pigment color is added. The mixture is then mixed for about 11 seconds at a temperature of about 82.7 C. The temperature can be measured by e.g. the use of a temperature measuring gun.

[0087] Twelve grams of the mixture is next poured into each mold (with the mold having a height of about 25 mm), after which the bottom of each mold is scraped to prevent air bubbles from appearing in the soap. In certain embodiments, a rubber or silicone device is used to scrape the bottom of each mold. More of the mixture is then slowly poured into the mold to the desired height. In certain embodiments, the mixture is contained in and is slowly poured into the mold from a glass flask to eliminate bubbles, particularly at any desired area that should have a smooth surface, such as a logo area.

[0088] A sponge is then placed into each individual mold and the soap is allowed to sink into the sponge. Approximately 4 mm of the sponge should remain above the top level of the soap. The molds containing the soap and sponge are them placed in a refrigerator for cooling at at approximately 15 C. for about 2 hours and until the soap is solid.

[0089] Immediately after removing the mold from the refrigerator, the soap sponge is removed from the mold and wrapped with a plastic film to avoid deterioration.
