Description

  The present invention relates to a soap and a method for producing the same, and more particularly to a solid soap with reduced skin irritation, particularly a soap that can be used as a facial soap or a cosmetic soap, and a method for producing the same.

  Conventionally, various solid soaps formed using vegetable oil components have been proposed. For example, in Patent Document 1 (Japanese Patent Application Laid-Open No. 2004-99851), in order to provide a mineral-containing cosmetic soap that is gentle on human skin and is useful for skin health by being used for bathing and facial washing, Solid soaps containing 10% by weight, olive oil 0.5-5% by weight and turmeric 0.1-3% by weight have been proposed.

  Patent Document 2 (Japanese Patent Application Laid-Open No. 2005-264128) has the effect of preventing the occurrence of acne and pimples, the use of those with atopic diseases and eczema, and the effect of suppressing body odor, as well as the prevention of the occurrence of spots and freckles. A whitening soap production method has been proposed in which whitening whitening effect is noticeable. Especially, as vegetable oil used for soap production, grape seed oil is the main raw material, and olive oil, coconut oil and palm oil are used as appropriate. It has been proposed to mix in proportions.

  Furthermore, Patent Document 3 (Japanese Patent Application Laid-Open No. 2007-56174) discloses photosynthetic bacteria, lactic acid bacteria, and yeast as ingredients in order to provide soap that contributes to the improvement of symptoms of athlete's foot and beetles without contaminating socks and the like. Soaps containing a large amount of useful microorganisms such as fungi, actinomycetes and bacilli have been proposed. However, in this document, regarding the method for producing the soap, a useful microorganism group is mixed in a liquid composed of other soap components (oil and fat, sodium hydroxide and starch), and then placed in a mold and left for about 2 months. Only the timing of the saponification reaction and the addition of useful microorganisms is not taken into consideration. In addition to starch, salad oil (3 liters) is used as fat.

  As described above, soaps that can be used for reducing skin irritation and atopic diseases have been proposed in the past, and useful microorganism groups (hereinafter referred to as EM) to improve the symptoms of athlete's foot and beetle. Soaps that use bacteria are also proposed.

  However, the actual situation is that there has not been proposed a substance that improves hypoallergenicity to the skin while simultaneously improving the effect after use. Further, the soap used for washing will be sufficiently washed away by the subsequent rinsing, but it may be slightly left on the skin depending on the rinsing method.

  Therefore, the first object of the present invention is to provide a soap that improves the feeling of use after use while pursuing low irritation to the skin, and can effectively remove the soap even if it remains after washing. And

  In addition, as described above, although a soap using a useful microorganism group has been proposed, the fact is that the useful microorganism group cannot be effectively used due to problems in its production method.

  Then, this invention reconfirms the manufacturing method of soap, and makes the manufacturing method of the soap which can utilize a useful microorganism group effectively as a 2nd subject.

  As a result of diligent development to solve the above problems, the present inventor is a soap formed using vegetable oil, especially olive oil, and blends microbial components such as useful microorganisms with such vegetable oils and fats. Thus, the present invention has been completed by finding that it has a good synergistic effect on the skin during and after use.

  That is, in order to solve at least one of the above-mentioned problems, the present invention is olive oil, castor oil, palm oil, palm kernel oil, palm stearic acid, coconut oil, rice bran oil, safflower oil, sesame oil, camellia oil, One or two or more vegetable oil components selected from vegetable oils including corn oil, cottonseed oil, soybean oil, sunflower oil, an alkaline component that reacts with the vegetable oil components to produce soap, and the above plant properties Provided is a soap comprising a microbial component blended in an amount of 0.5 to 6 parts by volume with respect to 100 parts by volume of an active ingredient comprising an oil and fat component and an alkali component.

  Such soaps are further used as auxiliary components such as soil release polymers, polymer dispersants, polysaccharides, abrasives, bactericides, anti-fogging agents, builders, enzymes, opacifiers, dyes, fragrances, thickeners, antioxidants. , At least one selected from the group consisting of processing aids, other soap foaming enhancers, buffers, antifungal agents or mold control agents, insect repellents, rust preventive aids, and chelating agents You can also However, the blending amount is desirably within a range that does not deviate from the requirement of low irritation to the skin. Rather, it is desirable not to add these additives in order to reduce irritation to the skin. That is, it is desirable that the soap according to the present invention is formed with only vegetable oil components, alkaline components, and useful microorganisms. Note that when starch is added as a nutrient for microbial components, the quality change of the component during storage must be taken into account, and it may be possible to increase irritation to the skin. Then it is not necessary to mix.

  In the soap according to the present invention, it is desirable to use a vegetable oil derived from fruits typified by olive oil as the vegetable oil component. Further, among the olive oils, virgin olive oil is preferable, and among them, the free acidity is preferably 2 g or less per 100 g in terms of oleic acid (that is, extra virgin olive oil and virgin olive oil).

  By using such olive oil, even when soap remains on the skin after washing, the irritation to the skin by the soap is reduced, and the moisture retention in the skin can be further increased. As a result, even if a person suffering from dermatitis such as an atopic disease is used, since there is little irritation to the skin, it is possible to improve the symptoms. Moreover, by using olive oil as a vegetable oil component, even when it is formed as a solid soap, it can be used for a long time without losing its shape.

  Moreover, as an alkaline component which can be used for manufacture of the soap concerning this invention, various alkaline components currently used for manufacture of soap, such as potassium hydroxide and sodium hydroxide, can be used. In particular, sodium hydroxide is used when manufacturing a soap bar, while potassium hydroxide is used when manufacturing a liquid soap. However, since the soap according to the present invention is intended to be hypoallergenic to the skin and interact with useful microorganisms, the alkali component used for saponification is preferably sodium hydroxide, and thus solid It is desirable to be a soap.

  Therefore, the soap according to the present invention is desirably solid and appropriately formed into a three-dimensional shape. This three-dimensional shape means the fluid is excluded, and may be powder, and is preferably a shape having a certain size. The shape includes various shapes such as a sphere, a vertical body, a column, a shape combining a spherical surface and a plane, and other shapes such as a star shape, a heart shape, and a character shape. There is no particular problem with the size as long as it is suitable for use.

  The soap according to the present invention further contains a microbial component consisting of a group of useful microorganisms in a volume ratio of 0.5 to 6%, preferably a volume ratio with respect to an active ingredient consisting of a vegetable oil and fat component and an alkali component. 0.5% to 4% is blended. If the amount is less than 0.5 with respect to 100 parts by volume of the active ingredient of soap, the effect based on this useful microorganism group cannot be sufficiently obtained. On the other hand, even if the amount exceeds 6 parts by volume, the effect does not change so much. This is because the material is wasted.

  The group of useful microorganisms constituting such a microbial component includes a plurality of useful microorganisms, such as lactic acid bacteria group, yeast group, photosynthetic bacteria group, fermentation filamentous fungus group, and Gram-positive actinomycetes group, anaerobic and microaerobic microorganisms. It is an aggregate that coexists with each other, and is a symbiotic microbial material. However, it is desirable that the microorganism used for the microorganism material is a safe type used for food processing, such as yeast and lactic acid bacteria. The useful microorganism group used as such a microbial component may use, for example, trade names “EM1 to 3”, “EMW”, “EMX” and the like provided by EM Research Institute, Inc. and Sanko Sangyo Co., Ltd. it can.

  The above-mentioned useful microorganism group has strong anti-oxidant power, so it can be added to soap to prevent oxidative degradation of organic substances by (oxidizing) microorganisms in the atmosphere with high oxygen content. It is thought that it can be changed to a biodegradable good cycle.

  In addition, by adding a microbial component consisting of such useful microbial groups, the decomposition of the surfactant that is a soap maintenance component is promoted, and even if the soap component remains on the skin, The effect on the skin can be reduced. Furthermore, the action of promoting the decomposition of the surfactant by the useful microorganism group also promotes the decomposition of the surfactant in the waste water generated during the cleaning, and thus can contribute to environmental conservation.

  In the soap according to the present invention, vegetable oil and fat, particularly oil derived from olive oil is used as the main component of the soap, so that metal and other inorganic substances do not remain on the skin due to decomposition by the useful microorganism group. Disassembled. And since the useful microorganisms adhering to the skin at the time of use of soap are hold | maintained at about 36 degrees Celsius optimal for the activity, the activity of the useful microorganisms is also activated and a more remarkable effect can be obtained. I can do it.

  Furthermore, in order to solve at least any one of the above-mentioned problems, the present invention provides a method for producing soap that can effectively cause a group of useful microorganisms in the soap.

That is, a method for producing a soap containing the above useful microorganism group,
(A) an alkali component creating step for creating an alkali component which is the property of an aqueous solution;
(B) a first mixing step of mixing the vegetable oil component and the alkali component;
(C) comprising a second mixing step of mixing and mixing microbial components in a mixed suspension of vegetable oil and fat components and alkali components,
The second mixing step is a method for producing soap performed at less than 60 degrees Celsius.

  In such a production method, heat is generated when sodium hydroxide or the like is dissolved in water in order to produce an alkali component, which may be 60 degrees Celsius or more. If a microbial component is mixed in such a temperature environment, the microorganism may be killed. Therefore, in the present invention, an alkali component is first prepared, and the temperature of the suspension is lowered by mixing and stirring the vegetable oil in the first mixing step, which is less than 60 degrees Celsius, preferably 40 degrees Celsius or less. At this stage, the microbial component is mixed in the suspension in the second mixing step and further mixed.

  By passing through such a manufacturing process, there is no possibility that the useful microorganism group constituting the microbial component will be killed at 60 degrees Celsius or more, and it can be effectively present in the manufactured soap. Furthermore, the saponification of the alkali component and the vegetable oil / fat component is performed at a high temperature by the heat generated in the alkali component preparation step, so that the saponification reaction is sufficiently accelerated.

  Thus, the soap produced by the method for producing a soap according to the present invention has a large number of microorganism components that are not inactivated therein, and therefore can effectively generate enzymes in the skin at body temperature. .

Schematic diagram showing the manufacturing process of the soap bar according to the present embodiment Schematic showing the soap bar according to this example

  Hereinafter, the soap according to the present embodiment, in particular, the solid soap and the manufacturing method thereof will be specifically described with reference to the drawings.

  First, the solid soap according to the present embodiment is manufactured by using olive oil as a vegetable oil component and using sodium hydroxide as an alkaline component and reacting (saponifying) the two. In the production of this soap bar, 4000 cc of olive oil and 560 cc of sodium hydroxide are used, and 100 cc of microbial components consisting of useful microorganisms are used. When molding such soap bars for washing, a saponification reaction product is poured into a mold, cooled, dried and aged, and if necessary, it is molded after demolding.

  Specifically, as shown in the soap manufacturing process diagram of FIG. 1, first, 560 cc of sodium hydroxide 20 is added to 560 cc of water 21 and stirred until both are sufficiently mixed (about 15 minutes). Mix to create an alkali component (alkali component creation step a). This alkaline component preparation process is an exothermic reaction and may exceed 60 degrees Celsius, depending on the environment in which it is carried out.

  Then, 4000 cc of olive oil 30 is added to the prepared alkali component, and further stirred and mixed for about 30 minutes to perform a saponification reaction (first mixing step b). As a result, the mixed solution 50 is in a suspended state, and the heat generated in the alkaline component preparation step (a) is also released, and the temperature drops to about 40 degrees Celsius.

  Thereafter, 560 cc of the microbial component 40 sold under the name of EM (Effective Microorganisms: useful microorganism group) is mixed in this suspension mixed solution, and this is stirred and mixed for about 5 minutes (second mixing step c). When the EM is charged, it is desirable to appropriately control the temperature of the mixed suspension with a thermometer 70 or the like.

  Then, the solution 50 can be poured into a molding die 80 (molding step D), aged for 2 days to 1 week after being put in the die, and then removed from the mold. It should be noted that the stirring step in this manufacturing method is not required to be so rigorous with respect to the stirring speed or the like, and may be performed manually, depending on the amount to be manufactured.

  In particular, in all of the above steps (i) to (d), since the raw material is not heated at all, not only can the generation of carbon dioxide being restricted as a global warming gas be suppressed, Since saponification can be performed with the amount of water initially charged, it becomes easy to manage the moisture in the soap produced. Furthermore, the effect that the inactivation of the useful microorganism group can be surely avoided can be obtained. And when it is made by a cold process without heating, olive oil, which is a raw oil component, remains in the soap, which moisturizes the skin and activates useful microorganisms. It is done. That is, by using olive oil and making it by a cold process, it is not necessary to add a nutrient of a useful microorganism group such as starch separately.

  Drawing 2 (A)-(E) has shown the whole shape of the bar soap concerning this embodiment. That is, the entire shape of the soap formed by molding is shown. As shown in this figure, the soap bar according to the present embodiment can be formed in various shapes as having a certain area and thickness. In particular, when the soap is used in a net or cloth bag, the size of the soap is, for example, when it is formed into a spherical solid soap 10 as shown in FIG. Has a diameter of about 15-40 mm. Moreover, when it forms in the column-shaped solid soap 11 as shown in FIG.1 (B), the diameter shall be about 20 mm and axial center length shall be 10-30 mm. Moreover, when it forms in the prism-shaped solid soap 12 as shown in FIG.1 (C), all the side lengths shall be 15-30 mm. Moreover, when it forms in the pyramid-shaped solid soap 13 as shown in FIG.1 (D), all the side lengths shall be 20-40 mm. It can also be formed as a solid soap 14 having various designs such as a star shape as shown in FIG. 1E, and preferably has a volume of about 60 cc.

  According to the solid soap produced as described above, washing with slightly warm water of about 35 degrees Celsius activates the useful microorganism group and can suppress the propagation of various bacteria. Even when the soap component remains, the solid soap according to the present embodiment is formed using olive oil, and no extra components such as other fluorescent paints are blended. Has been reduced. Furthermore, this soap contains a microbial component consisting of useful microorganisms, and the excess soap component is decomposed by this useful microorganisms activated at body temperature, so that the irritation to the skin is greatly increased. Has been reduced. Furthermore, since it contains a microbial component, environmental pollution due to water after rinsing is reduced.

  Further, if a microorganism component that has been approved for oral administration is selected, it can be used for mouth washing, for example, and by the action of useful microorganisms, periodontal disease bacteria that cause alveolar pyorrhea can be used. Removal can also be performed.

  In this example, the following soap was prepared for comparison with the soap prepared in the above embodiment (hereinafter referred to as “the present soap”). The soap prepared in the above embodiment is saponified by mixing 560 cc of sodium hydroxide with 560 cc of water and then mixing 4000 cc of olive oil as a vegetable oil component. After that, when the suspension solution reaches 40 degrees Celsius, 100 cc of the microbial component consisting of a group of useful microorganisms sold under the name of EM is added and mixed, then molded, cooled, dried and aged. Formed.

[Comparative Soap 1] Comparative soap 1 was prepared in the same manner except that in the production of the soap, olive oil as a vegetable oil component was replaced with 4000 cc, and mixed oil of beef tallow, coconut oil and palm oil was used. .
As a result of using this comparative soap 1, it was confirmed that the skin was washed up as if a film was stretched on the skin. In addition, there was a person who developed a rash with the feeling that the pores were clogged.

[Comparative Soap 2] In the production of the soap, a microbial component consisting of a group of useful microorganisms was added immediately after the alkaline component preparation step, and then a vegetable oil component was blended and saponified to prepare a comparative soap 2 .
As a result of using this comparative soap 2, as for the feeling of washing, the same effect as that of the soap was obtained, but the improvement effect for those having skin diseases such as athlete's foot was not obtained. In this regard, when this soap was used, itching over the skin disease after washing was reduced over a long period of time.

[Comparative soap 3] In the production of the soap, comparative soap 3 was prepared without blending microbial components consisting of useful microorganisms.
As a result of using this comparative soap 3, as with the comparative soap 2, the same effect as that of the soap was obtained with respect to the feeling of washing, but the improvement effect for those having skin diseases such as athlete's foot was obtained. There wasn't.
