Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scrub soap in which a plurality of granular scrub materials are arranged in soap, and a method for producing the scrub soap.

[0002]

2. Description of the Related Art Conventionally, a so-called scrub soap in which a plurality of granular scrub members are arranged in soap is known. In this conventional scrub soap, a resin such as tree nut or polyethylene is formed into a scrub material, and the scrub material is arranged in the soap. By doing so, for example, when paint, paint, oil, etc. adheres to the hand, scrubbing material can be used to easily remove stains that are difficult to remove with normal soap, and the skin is rubbed to improve blood circulation. It is a thing.

On the other hand, there has also been proposed a scrub soap in which a scrubbing material is composed of a wax such as carnavallo or candelillaro, which is the main component, and the scrubbing material is arranged in soap. By doing this, scrub material,
It can be made softer than polyethylene and the like, and it can improve the feel of the skin during cleaning. Also, after use, the wax oil acts as a superfatting agent, and the skin can be appropriately replenished with oil.

However, such a scrub soap has different effects depending on the type of scrubbing material, and is convenient for removing dirt such as oil when using a scrubbing material made of a relatively hard material such as resin. However, some people may get rough skin. In addition, the manufacturing cost is increased by the amount of scrubbing material that has to be provided as compared with the soap that does not have a normal scrubbing material. Therefore, there is a problem that it is uneconomical to use constantly. Therefore, for example, a soap provided with a scrubbing material when paint, paint, oil, etc. adheres to the hand, a soap having no scrubbing material in the normal case, or the like, or
If the paint or oil is very dirty, first use soap with a scrub material made of resin such as tree nuts or polyethylene to remove some dirt, and then scrub the wax as the main component. If one soap can be used selectively, such as using a soap provided with a material to prevent rough skin, it can be used effectively, and is economical and convenient.

DISCLOSURE OF THE INVENTION The present invention has been proposed in view of the above circumstances. The object of the present invention is to selectively use a scrubbing material with one soap in accordance with the usage situation. It is intended to provide a scrub soap and a method for producing the scrub soap.

[0006]

The present invention solves the above problems by providing a scrub soap having the following features. The scrub soap of the present invention is composed of a plurality of soap layers having different specific gravities. These soap layers are sequentially laminated in layers from one having a large specific gravity to one having a small specific gravity. Also, at least one soap layer includes a plurality of scrubbing materials composed of particles. The scrubbing material has a specific gravity substantially the same as the specific gravity of the soap base of the soap layer on which the scrubbing material is arranged.

The present invention also solves the above problems by providing a method for producing a scrub soap having the following features. The method for producing a scrub soap of the present invention prepares several kinds of soap bases having different specific gravities. Meanwhile, at least one type of scrubbing material formed so as to match the specific gravity of the soap base is prepared. Then, the soap base and the scrubbing material are mixed in a state where the soap base has fluidity. After that, they are simultaneously cooled and solidified. The term “having fluidity” as used in the present invention means a state in which, when the soap base and the scrub material are mixed, the scrub material can move inside the soap base.

An embodiment of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a perspective view of a scrub soap 1 of the present invention. Scrub Soap 1 of the Invention in this Example 1
As shown in FIG. 1, is composed of two layers, an upper soap layer 2 on the upper side and a lower soap layer 3 on the lower side.

The upper soap layer 2 is made of transparent soap colored red and has a smaller specific gravity than the lower soap layer 3. Inside the upper soap layer 2, a plurality of granular scrubbing materials 4 ... 4 are arranged so as to be dispersed substantially uniformly.

As the scrubbing material 4, various materials such as tree nuts, polyethylene, cellulose, styrene, wax and pigment can be applied. In this embodiment, a resin containing polyethylene as a main component is used, and its specific gravity is the upper soap. Layer 2
It is said to have the same specific gravity as the soap base that forms the. The specific gravity of polyethylene alone is about 0.9, but it can be appropriately adjusted by appropriately mixing a specific gravity adjusting agent such as calcium carbonate or titanium oxide. For example, by mixing 15% by weight of calcium carbonate, the specific gravity can be adjusted to about 1.1, and by adjusting the amount of calcium carbonate appropriately, the specific gravity can be adjusted to the same level as the soap base of the upper soap layer 2. it can.

The lower soap layer 3 is made of blue-colored transparent soap, and the scrubbing material 4 like the upper soap layer 2 is used.
4 is not included, and is composed only of a transparent soap base.

Although the boundary surface 5 between them is drawn by a solid line in the figure, there is no step due to simultaneous cooling and solidification of both in the same container as described later,
The boundaries of the colors are clearly visible, creating an aesthetic effect. In addition, the interface 5 does not peel off during use.

In order to produce the upper soap layer 2 and the lower soap layer 3 having different specific gravities, 65 ° C. to 7 ° C. after the saponification reaction is completed.
While maintaining the temperature at 5 ° C, the transparent soap matrix obtained by blending sucrose or the like is separated into two in a molten state. Then, the compositions of the respective transparent soap substrates are changed so that the specific gravity is different. The specific gravity can be changed by changing the composition of the transparent soap. Specific examples of the factors that can be mentioned are alcohols, glycols, and saccharides, and any one of them can be increased or decreased to change the specific gravity. it can.

When the specific gravity is changed only with alcohols such as ethanol, the specific gravity is reduced by adding at least 10% or more of ethanol to the heated and melted liquid soap, and the ethanol is added. It can be clearly separated from the former one by adding ethanol to the upper part and to the lower part to the lower part in a liquid form by heating and melting. The limit of the amount of ethanol to be added is 100 with respect to 100 of the weight of fats and oils at the time of preparation, and if it exceeds 100, the soap becomes whitish after solidification and the moldability deteriorates. May be deposited.

In the case of only glycols such as glycerin, the specific gravity becomes heavy when at least 4% or more of glycerin is added to the weight of the liquid soap heated and melted, and glycerin is added in the liquid heated and melted. The lower part can be clearly separated, and the one before the addition can be clearly separated on the upper part. Also, the limit of glycerin to be added is 100 with respect to 100 of the weight of oil and fat at the time of preparation.
It does not solidify or feels sticky.

In the case of only sugars such as white sugar,
At least 2% by weight of the liquid soap heated and melted
When the above-mentioned sucrose is added, the specific gravity becomes heavy, and in the heated and melted liquid, it is possible to separate the sucrose into the lower part and the sucrose into the upper part. The maximum amount of sucrose to be added is 63 with respect to the weight of 100 parts of fats and oils at the time of charging, and if it exceeds the limit, it may become soft or may not solidify.

Usually, the above three factors are used in combination to increase the difference in specific gravity, so that transparency can be maintained and separation can be achieved in the molten state by heating. The temperature for mixing is preferably about 50 ° C to 60 ° C. The specific gravity of the transparent soap base material forming the upper soap layer 2 is adjusted to be smaller than that of the lower soap layer 3 and to match the specific gravity of the scrubbing material 4. The method for adjusting the specific gravity of the upper soap layer 2 and the scrubbing member 4 is to adjust both of them to a specific gravity value set in advance, or to adjust the upper soap layer 2 to the previously formed scrubbing member 4, or vice versa. The scrubbing material 4 can also be combined with the upper soap layer 2.

On the other hand, the coloring may be performed by adding an appropriate pigment to each of the liquid transparent soaps before or after changing the above-mentioned specific gravity.

Then, the obtained two transparent soap bases having different specific gravities are put in the same container together with the plurality of scrub members 4 ... 4 whose specific gravities are adjusted. The reason is that there may be a slight time difference as long as the transparent soap base is in a fluid stage. In addition to putting the transparent soap base and the scrubbing material 4 in the container at the same time, the transparent soap base may be added first, or The scrubbing material 4 ... 4 may be put in first. Further, the scrubbing materials 4 ... 4 may be arranged in advance with the transparent soap base material when the specific gravity is adjusted to the transparent soap base material to be arranged.
As a result, in the molten state, the transparent soap base can be naturally separated in layers from one having a large specific gravity to one having a small specific gravity. Further, at that time, the scrubbing materials 4 ... 4 move together with the transparent soap base material having a matching specific gravity, are disposed only in the transparent soap base material having a matching specific gravity, and are naturally dispersed.

After that, by cooling and solidifying, the layers can be simultaneously dried integrally, and the step of the boundary surface which occurs when the liquid soap is poured onto the solidified solid is prevented, and It is possible to draw the boundary surface 5 clearly by preventing color unevenness on the boundary surface. Further, it is possible to prevent the peeling from the boundary surface during use, which occurs when the two solidified soap pieces are adhered by an adhesive material or the like.

With the above-described structure, the upper soap layer 2 or the lower soap layer 3 can be selectively used. For example, when paint, paint, oil, etc. are attached to the hand, the upper soap layer 2 is used.
The lower soap layer 3 which does not include the scrubbing material can be used in the normal case.

Next, another embodiment will be described with reference to FIG. In this embodiment, the upper soap layer 2, the middle soap layer 6 and the lower soap layer 3 are laminated in three layers.

These layers are such that the upper soap layer 2, the middle soap layer 6 and the lower soap layer 3 have higher specific gravity in this order. Further, the upper soap layer 2 and the lower soap layer 3 include scrubbing members 4 ... 4 therein. 4a of the upper soap layer 2 is mainly composed of wax, while the scrub members 4b ... 4b of the lower soap layer 3 is mainly composed of polyethylene.

Scrub material 4a containing wax as a main component
4a can be composed of any wax having a melting point higher than that of the soap base, and examples thereof include carnavallo, candelilla, sugar cane roast, ceramic roe, chew claw, palm roe, and mitsulo. Then, it can be obtained by forming one kind or two or more kinds selected from these into particles and then impregnating this with a specific gravity adjusting agent. The obtained scrubbing materials 4 ... 4 can be formed to be softer than those made of polyethylene or the like, and can be made to have a good texture when washed. Further, after use, the wax oil acts as a superfatting agent, and the oil can be appropriately replenished to the skin.

As the specific gravity adjusting agent, titanium oxide, calcium carbonate or glycerin can be used. Specifically, a wax in a molten state composed of carnavallo, candelilla, etc. is sprayed into water to be cooled and solidified to form a granular wax having a hollowed shape. Then, by immersing this in glycerin having a specific gravity of about 1.2 for a predetermined time, the hollowed portion can be impregnated and the specific gravity can be adjusted.

Then, the specific gravity of each of the upper soap layer 2, the middle soap layer 6 and the lower soap layer 3 is adjusted in the same manner as in the above embodiment, while the scrubbing material 4b ...
Is adjusted to the same level as the specific gravity of the soap base of the lower soap layer 3, and a scrub material 4a ...
Are matched with the specific gravity of the soap base of the upper soap layer 2, and then they are cooled and solidified in the same container to laminate the three layers shown in FIG. You can get scrubbing soap.

By doing so, for example, when the hand is heavily soiled with paint, paint, oil, etc., the upper soap layer 2 provided with the scrubbing material 4a made of polyethylene resin is used to a certain extent. And then the lower soap layer 3 provided with the scrubbing material 4b containing wax as a main component is used to quickly remove dirt, and finally the wax oil acts as a superfatting agent. You can get rid of rough skin.

It should be noted that the scrubbing materials 4 ... 4 may be colored with the same color as the soap layer provided by mixing a pigment or with a different color. Examples of pigments include inorganic pigments such as ultramarine, cadmium yellow, red iron oxide, chrome yellow, lead white, titanium white, and carbon black, or organic pigments such as azo-based, triphenylmethane-based, quinoline-based, anthraquinone-based, and phthalocyanine-based pigments. ..
