Title: Absorbent soap

Description:
BACKGROUND OF THE DISCLOSURE 
     1. Field of the Invention 
     The present disclosure relates to absorbent soaps, and specifically relates to an absorbent soap with multiple functions and the method of making the same. 
     2. Description of Related Art 
     The bar soap commonly found in the market are used by rubbing the soap onto a user&#39;s body with water, so as to convert the solid soap into liquid state. The user can maintain personal hygiene using the liquid soap having cleansing property. 
     Most of the conventional soap structures are solid bar soap structures, and a few are hollow bar soap structures. With the conventional design of the soap structure, the area of the soap, which comes in contact with water, is only limited to the outer surface of the soap preventing water from penetrating deeply into the soap to dissolve the soap, when the soaps is used. For example, conventionally some soap is made by soaking loofah mesh in liquid soap which later solidifies to form loofah soap. Even though the loofah soap has plenty of pores resulted from filling the loofah mesh, the design of the loofah soap still is not able to efficiently enhance the dissolving rate of the soap. To the contrary, the benefits of the loofah mesh in terms of water-absorbing and foaming enhancement are not utilized in conventional design. 
     Recently, in order to solve the issue of the dissolving rate of the conventional soap, liquid detergents become replacements. However, for using a liquid detergent, the amount of the liquid soap is difficult to control, which could be wasteful. Regarding efficiency, many liquid detergents are not foamable when applied directly onto the skin, and users sometimes feel that the skin is not washed clean, leaving a slimy feeling. Therefore, when liquid detergents are used, additional foaming tools such as sponge and bath ball are usual companions for foaming to achieve better cleansing efficiency. 
     The design of the cleansing and caring properties of the conventional soap structures is implemented during the saponification. However, the quality of the design after curation can be limited and affected by the alkaline environment during saponification, which results in the disablement of exhibiting the functions of the added materials by failing to achieve expected effects. 
     SUMMARY OF THE DISCLOSURE 
     The present disclosure provides an absorbent soap which may include water-moisture absorbing materials and cleansing-caring materials to form a stacked structure with multiple properties. The absorbent soap includes at least a cleansing-caring layer which comprises body cleansing-caring materials with easily shapeable property in the shape of powder, granular, liquid, film, sheet, paste, gel, filament or the like; and at least an absorbent layer which comprises water-moisture absorbing materials. The absorbent soap having a stacked structure with multiple functions is formed by combining said cleansing-caring layer and said absorbent layer in a non-specific stacking format. The structure creates extra spaces within and between each of the cleaning-caring layer and absorbent layer to retain air, so that water from outside can take over the air spaces inside the soap, when the soap is used. The water molecule can further and continuously dissolve the cleansing-caring materials in the absorbent soap utilizing a larger tightly-contacted surface. It improves the dissolving efficiency of said cleansing-caring materials and still maintains the functions of the original materials. The present disclosure ultimately solves the problems of the conventional bar soap in terms of dissolving efficiency and maintaining the functions of the original materials through the design of the absorbent soap which is easily shapeable and can be stacked in a non-specific format. 
     The other advantage of the absorbent soap of the present disclosure is that any combination of the water-moisture absorbing materials and cleansing-caring materials in the finished products can be optionally removed, replaced or added. It enables each material in the soap to exhibit the functions of the original material without affected by the saponification, when the soap is used. 
     The formed absorbent structure enables a more efficient dissolving reaction to take place between the cleansing-caring material and the water molecules from outside, when the soap is used. It enhances the dissolving efficiency of the cleansing-caring materials and maintains the functions of the original materials. 
     In order to enable the cleansing-caring layer in the stacked structure of the absorbent soap of the present disclosure to satisfy the stacked structure in a non-specific format and to be squeezed or transformed by external force after the soap is made, the appearance of the cleansing-caring materials may have an easily shapeable property in the shape of powder, granular, liquid, film, sheet, paste, gel, filament, or the like. 
     The cleansing-caring layer of said absorbent soap may include moisturizing material such as vegetable oils or marine mud; fragrance material such as concentrated fragrance oils or fragrance essences; exfoliation material such as white charcoal (Binchö-tan) particles or fruit kernel powders; cleansing material such as soaps, amino acids, phospholipids, surfactants, or sea salt; or caring material such as hyaluronic acid, collagen, vitamin E or Chinese herbal medicine. 
     The absorbent layer of said absorbent soap may include water-moisture absorbing materials such as spunlace nonwoven fabric, nonwoven fabric, PET fiber nonwoven fabric, biodegradable fiber nonwoven fabric, cotton, dried plants, sponge, gauze, nylon yarn, fibrous plant, or porous (multiple holes) materials or water-soluble materials. 
     In order to achieve a more efficient dissolving rate of the absorbent soap, the thickness of the absorbent layer is preferably in the range of 0.01 to 30 mm and the thickness of the cleansing-caring layer is preferably in the range of 0.01 to 8 mm.

     Referring to the embodiment of  FIG. 2 , the present disclosure provides a design of an absorbent soap having a stacked structure with multiple functions. Said absorbent soap may include one or more layer(s) to react with water: cleansing soap layer  22 , soap  25  and honey capsule caring layer  27 ; and one or more absorbent layer(s) consisting of water-moisture absorbing materials to provide spaces to exchange for the water molecules from outside: spunlace nonwoven fabric  21 , dried plant  23 , cotton  24 , spunlace nonwoven fabric  26 . The aforesaid 7 layers were combined together in a square stacked manner vertically from the bottom to the top and then layers  21 - 26  were secured by sewing to form an absorbent soap having square stacked structure. 
     Referring to the embodiments of  FIGS. 4 and 5 , the present disclosure provides a spirally stacked absorbent soap. Said absorbent soap included: a cleansing layer  41  with the thickness of 3 mm comprising powder soap to react with water; a gel-like caring layer  42  with the thickness of 6 mm comprising grape seed oil, fruit kernel powder, and concentrated rose oil with the functions of moisturizing, exfoliating and fragrant; and one or more layer(s) of absorbent layers (spunlace nonwovens  43 ,  44 ,  45  and sponge  46 ) with the total thickness of 15 mm comprising water-moisture absorbing materials to provide spaces to exchange for water molecules from outside. The aforesaid 6 layers were combined together in a square stacked manner vertically from the bottom to the top. Due to the shapeable property of the stacked structure, the stacked layers were rolled forward and secured with an adhesive to form a spiral absorbent soap having cleansing and caring functions. 
     Said absorbent soaps can be designed as the combination of the square stacks shown in  FIGS. 1 and 2 . In order to provide better visual senses for the users and more efficient dissolving rates of soap, said absorbent soaps can be designed as a concentrically cylindrical absorbent soap as shown in  FIG. 3 , a randomly stacked absorbent soap shown in  FIG. 6 , and the absorbent soaps having other stacked structure. 
     Besides having water-moisture absorbing materials, such as spunlace nonwoven fabric, cotton, or dried plant in the absorbent layer of said absorbent soap, the water-moisture absorbing materials can further be substituted by other water-moisture absorbing materials with same functions, such as sponge, woven fabric, nylon yarn, non-woven fabric, PET fiber nonwoven fabric, biodegradable fiber nonwoven fabric, loofah mesh, Chinese herbal medicines, fibrous plants (such as coconut fibers or rice hulls), porous (multi-holes) materials, water-soluble materials (such as capsules), or the like. 
     The cleansing layer of said absorbent soap can be substituted with other cleansing materials with same functions other than soap, such as amino acids, phospholipids, surfactants, sea salt or the like. 
     The caring layer of said absorbent soap may be substituted with moisturizing materials such as vegetable oils, marine mud, honey or the like; or fragrance materials such as concentrated fragrance oils, fragrance essences or the like; or exfoliation materials such as white charcoal (Binchö-tan) particles, kernel powders or the like; or caring materials such as hyaluronic acid, vitamin C, collagen, vitamin E, or the like.
