Description

  The present invention relates to a polishing detergent containing cocoa powder obtained by squeezing cacao mass as an active ingredient for polishing cleaning action, and a dentifrice containing the cocoa powder.

  For cleaning agents such as toothpaste, toothpaste, face-washing foam, body soap, dishwashing detergent, kitchen detergent, bathroom and toilet cleaner, car body detergent, etc. There is something to include.

  In the cleaning by this polishing cleaning action, fine particles constituting the polishing component in the polishing detergent are added by rubbing and sliding on the polishing surface with a towel, sponge, palm, cleaning brush / toothbrush tip, etc. Dirt can be removed by mechanically acting on the object to be cleaned. Therefore, even if it is dirt that is difficult to remove by chemical dissolution / surfactant action, such as tea astringency, scale, rounding, etc., it is possible to easily remove the dirt by cleaning with the polishing cleaning action Become.

  In order to effectively exhibit such a polishing cleaning action, in addition to fine particles that are polishing components that give a mechanical polishing action, a wetting agent, a binder, etc. are blended to adjust the consistency of the polishing cleaning agent itself. It is necessary to ensure the dispersibility of the fine particles of the polishing component and the application / adhesion to the polishing surface. When used as a cleaning agent, in addition to abrasive cleaning agents, surfactants for enhancing the effect of foaming and dirt removal, and further, human skin such as toothpaste, toothpaste, face washing foam, body soap, etc. When used for oral or oral use, a flavoring agent, a flavoring agent, a refreshing agent, a coloring agent, a flavoring agent, and the like may be added to improve the feeling of use.

  For example, in dentifrices, in addition to calcium phosphate as a polishing detergent, preservatives, wetting agents, binders, foaming agents, stabilizers, pH adjusters, flavoring agents, flavoring agents, cooling agents, coloring agents, flavors What mix | blends various functional additives, such as an agent, is common.

  The polishing detergent as described above is generally composed of a synthetic compound as a main component, but since it is released into the environment as a rinse drain, it cannot be said that it is preferable from the viewpoint of environmental pollution. It is desired to provide a polishing detergent in which the main components are composed of natural materials with few such problems.

  For such a problem, for example, Patent Document 1 below includes, as a technique for using a natural material as a polishing component of a dentifrice, including pulverized rice husk particles that pass through a 200 mesh sieve as an essential tooth polishing agent, and polishing. A dentifrice is disclosed in which the total amount of the agent is less than 40% by weight of the total.

  On the other hand, as a technique for using a cocoa bean-derived composition in an oral composition, for example, Patent Document 2 below discloses an anti-periodontal disease fungus composition characterized by containing a cocoa component contained in cocoa mass as an active ingredient. It is disclosed that it can be used as a component of an oral cleaning agent that can safely and easily prevent periodontal disease. And in the Example, the toothpaste formed by mix | blending a cocoa hot-water extract is described.

Patent Document 3 listed below has a cacao powder as an additional component in an oral dental composition containing a fragrance selected from the group consisting of peppermint oil, spearmint oil, cinnamon oil and mixtures thereof as one component. A plaque-suppressing oral composition is disclosed, and a dentifrice containing cocoa powder is disclosed.
JP 58-85812 A International Publication No. 03/099304 JP 56-32410 A

  However, since the toothpaste disclosed in Patent Document 1 uses pulverized rice husk as an abrasive, it is necessary to limit the blending amount of the abrasive component in order to obtain a suitable consistency as an abrasive cleaner. Moreover, since the pulverized rice husk is a natural material, it is not a food material. Therefore, the pulverized rice husk could not have a function of imparting a fragrance, flavor or the like that improves the feeling of use when blended in an oral composition.

  Moreover, the dentifrice described in the said patent document 2 uses a cocoa extract as an anti-periodontal disease microbe component, and was not used as an active ingredient of an abrasive cleaning action. Furthermore, the plaque-suppressing oral composition described in Patent Document 3 contains cocoa powder as an anti-plaque component, but does not use cocoa powder as a polishing detergent, such as a water-insoluble phosphate. A dental abrasive was formulated as an abrasive cleaner.

  Accordingly, an object of the present invention is to provide a polishing detergent and a dentifrice which give a preferable feeling of use even when a natural material is a main component and it is applied to human skin or oral cavity.

  The inventors of the present invention have found that the cocoa powder obtained by squeezing cacao mass has a polishing and cleaning action unexpectedly, and have completed the present invention.

  That is, the polishing detergent of the present invention is characterized by containing cocoa powder obtained by squeezing cacao mass as an active ingredient for polishing cleaning action.

  According to the polishing detergent of the present invention, the fine particles contained in the cocoa powder exhibit a mechanical polishing action, and the components other than the fine particles contained in the cocoa powder can disperse the fine particles and affect the polishing surface. Since it is thought that application | coating and adhesiveness will also become favorable, a stain | pollution | contamination can be removed effectively. Moreover, a favorable feeling of use can be given with the fragrance and material feeling of cocoa powder.

  The polishing detergent of the present invention preferably contains 10% by mass or more of cocoa powder in the solid content. According to this, dirt can be removed more effectively.

  In the present invention, the polishing cleaning action means an action of the same quality as the action due to the function of a so-called polishing component in a cleaning agent or the like. In addition, although the specific mechanism of the polishing cleaning action by the cocoa powder is not clear, for the sake of convenience of description, the component of the cocoa powder that contributes to the polishing cleaning action is hereinafter referred to as the polishing cleaning ingredient of the cocoa powder. It is called.

  Another aspect of the present invention provides a dentifrice containing cocoa powder obtained by squeezing cacao mass in a solid content of 10% by mass or more.

  According to the dentifrice of the present invention, since the cocoa powder contains an anti-periodontopathic fungus component and a plaque formation suppressing component together with the above-mentioned polishing cleansing component of the cocoa powder, the daily oral cleaning work for maintaining a healthy oral cavity is efficient. Can be done. Moreover, since the active ingredient of the polishing cleaning action is the cocoa powder, it is preferable from the viewpoint of environmental pollution.

  The dentifrice of the present invention was selected from the group consisting of preservatives, wetting agents, binders, foaming agents, stabilizers, pH adjusting agents, flavoring agents, flavoring agents, cooling agents, coloring agents, and flavoring agents. At least one additive can be further blended. According to this, the composition suitable for a product form can be provided, making the said cocoa powder a main component.

  The polishing detergent of the present invention contains cocoa powder obtained by squeezing cacao mass as an active ingredient for polishing cleaning action, whereby mechanical polishing is performed by the fine particles in the cocoa powder, and the fine particles in the cocoa powder. Since it is considered that the dispersibility of the fine particles and the application / adhesion to the polishing surface are improved by the components other than the above, it is possible to effectively remove dirt. Moreover, a favorable feeling of use can be given with the fragrance and material feeling of cocoa powder. Therefore, the polishing detergent of the present invention can be suitably used for brushing teeth, for example.

  Furthermore, the dentifrice of the present invention is preferable from the viewpoint of environmental contamination because the active ingredient for polishing and cleaning action is the cocoa powder.

  The cocoa powder obtained by squeezing from the cacao mass used in the present invention can be prepared according to a known method. For example, it can be obtained as follows. That is, cocoa beans are taken out from cocoa fruits, and are usually fermented at about 30 ° C. for 4 to 7 days, and then dried. The dried cocoa beans are selected with a cleaner to remove foreign substances such as metals and stones, and then crushed with a separator to remove the skin, germs and the like to obtain cocoa nibs.

  The obtained cocoa nibs may be subjected to an alkali treatment for removing the bitterness and astringency of cocoa beans as necessary.

  The cocoa nibs obtained as described above are roasted at 100 to 150 ° C. for 20 to 120 minutes and ground with a grinder to prepare cocoa mass, and the resulting cocoa mass is squeezed with a cocoa press to obtain cocoa butter. Cocoa powder can be obtained by separating and pulverizing with a cocoa mill into a fine powder. The cocoa powder usually obtained has a cocoa butter content of about 15 to 25%, but in the present invention, the cocoa powder (cocoa butter content 8% is defined in the Fair Competition Rules for the Display of Chocolates). In addition to the above, defatted cocoa (cocoa butter content of less than 8%) that cannot be said to be cocoa powder in accordance with the above rules can also be used.

  Moreover, the cocoa powder used for a commercially available cocoa drink etc. can also be used as the cocoa powder used for the said invention.

  The cocoa powder used in the present invention is composed of protein, carbohydrate, dietary fiber (water-soluble indigestible polysaccharide, hemicellulose, cellulose, lignin, etc.), phospholipid, and inorganic substances (phosphorus, magnesium, calcium, iron, zinc, copper) , Potassium, sodium, etc.), vitamin A, vitamin B group, vitamin C, vitamin E (various tocopherols, etc.), niacin, oxalic acid, citric acid, malic acid, succinic acid, lactic acid, acetic acid, polyphenols (tannin, epicatechin) Catechin, quercetin, etc.), anhydrous caffeine, theobromine, various free fatty acids (palmitic acid, stearic acid, oleic acid, linoleic acid, etc.) and the like.

  The polishing detergent of the present invention preferably contains 10% by mass or more of the cocoa powder, more preferably 20 to 90% by mass, in terms of solid content. Moreover, you may contain the said cocoa powder 100 mass%.

  The polishing detergent of the present invention can be used as a polishing component suitable for cleaning agents such as toothpaste, toothpaste, face washing foam, body soap, dishwashing detergent, and the like.

  When used as the cleaning agent, in addition to the polishing detergent, for example, a wetting agent, a binder, a polishing aid, or the like for suitably exerting the function of the fine particles of the polishing component, chemical dissolution, etc. -You may mix | blend the surfactant for removing by surface active action, etc., and can raise the effect of dirt removal by it. Furthermore, in order to improve the feeling of use, a flavoring agent, a corrigent, a refreshing agent, a coloring agent, a flavoring agent, etc. can also be mix | blended.

  The polishing detergent of the present invention adheres to towels, sponges, palms, cleaning brushes, toothbrush tips, etc., applies the adhered surface to the dirt surface, and then removes dirt by applying friction and sliding. be able to.

  On the other hand, in the dentifrice of this invention, it is preferable to contain 10 mass% or more of cocoa powder obtained by pressing from cacao mass in solid content, and it is more preferable to contain 20-90 mass%. Moreover, you may mix | blend grinding | polishing components other than cocoa powder, such as calcium phosphate, but it is preferable that the content in the dentifrice solid content is 80 mass% or less.

  In the dentifrice of the present invention, a preservative, a wetting agent, a binder, a foaming agent, a stabilizer, a pH adjusting agent, a flavoring agent, a corrigent, a refreshing agent, as long as the preferred content of the cocoa powder is maintained. Additives for known dentifrices such as colorants and flavoring agents can be blended.

  Further, in the dentifrice of the present invention, a further oral cleansing effect can be expected by further blending an antibacterial agent and / or anti-plaque-forming agent within a range that maintains the preferred content of the cocoa powder. It is preferable because periodontal disease, plaque formation, caries, etc. can be prevented and a healthy oral cavity can be maintained.

  According to Patent Document 2 (International Publication No. WO 03/099304), the cocoa content contained in cocoa mass is effective as an anti-periodontal fungus composition, so that the toothpaste using the dentifrice of the present invention is used. At the time of work, the active ingredient from the cocoa powder acts on the teeth and gums, and the anti-periodontal fungus action effect can be expected together with the abrasive cleaning action according to the present invention.

  The form of the dentifrice of the present invention is not particularly limited, and examples thereof include a powder dentifrice, a moisturized dentifrice, a toothpaste, a liquid dentifrice, and the like, and can be used for daily dentifrice in the same manner as a normal dentifrice. .

  In the present invention, although the details of the mechanism by which the cocoa powder obtained by squeezing cacao oil exerts the abrasive cleaning action is not clear, insoluble dietary fibers such as hemicellulose and lignin contained in cocoa powder are substantially free of mechanical polishing. It is considered that lipids, saccharides, water-soluble dietary fiber, and the like contained in cocoa powder play an auxiliary role.

  EXAMPLES Hereinafter, the present invention will be specifically described with reference to examples, but these examples do not limit the scope of the present invention.

<Example 1> (Adjustment of polishing detergent)
A commercially available cocoa powder (trade name: “Pure Cocoa”, manufactured by Morinaga Seika Co., Ltd.) was suspended in distilled water to a concentration of 20% by weight to prepare a polishing detergent. This abrasive detergent had a viscosity comparable to that of a normal liquid dentifrice.

<Test Example 1> (Polish polishing test)
In order to compare the effectiveness of the polishing cleaning action of the polishing detergent prepared in Example 1 above, 20% by mass of calcium hydrogen phosphate (CaHPO ₄ ) as a representative of the polishing agent used in commercially available dentifrices. Distilled water was prepared as a suspension and a control, and all three test groups (20% CaHPO ₄ , 20% cocoa, distilled water) (hereinafter collectively referred to as a sample polishing solution) were compared.

  Bovine teeth that are widely used for dental in vitro experiments were used as the teeth for the polishing and cleaning test. Since there is a very thin cementitious layer on the bovine enamel surface, in order to bring it close to the condition of the human tooth surface, the cementum on the surface is used as a polishing agent (trade name: “Melsage Regular, Fine”, The cementum layer was removed by polishing with Matsukaze Co., Ltd. to expose the enamel. Further, in order to facilitate the dipping operation and the polishing operation, an aluminum rod having a diameter of about 2 mm was inserted into the pulp cavity and fixed with a resin resin.

In order to avoid experimental errors due to the color difference of the tooth surface inherent to the bovine teeth, the average value and standard deviation of the measured values and lightness L ^* values measured by a spectroscopic color difference meter, which will be described later, are made almost equal. 18 bovine teeth (bovine teeth No. 1 to 18) were selected and used for each test group as shown in Table 1 below.

  After immersing 60g of the above-mentioned bovine teeth in a black tea solution extracted with 90ml of 200ml hot water for 5 minutes and placing it in a 37 ° C incubator for 2 days to form a stain on the crown surface of the bovine teeth, It was taken out from the black tea solution and rinsed lightly with water to obtain a post-stained bovine tooth used in the following polishing cleaning test.

  The stained surface of the bovine tooth after the staining was attached by attaching the sample polishing liquid attached to the brush portion of a polishing brush (trade name: “Young Prophy Brush No. 0270”, manufactured by Young Dental Co., Ltd.). A polishing operation at a rotational speed of 5000 rpm was applied by a micro engine (trade name: “Osada BL-30”, manufactured by Nagata Electric Industry Co., Ltd.).

  As a polishing part, as shown in the center photograph in FIG. 1, a horizontal edge line connecting six horizontal arrows and a vertical line connecting two vertical arrows intersect, as shown in the center photo, Polishing was performed on three portions of the center and the gingival margin.

  Re-adjust the sample polishing solution every 1 minute so that the sample polishing liquid is not depleted with respect to the three color tone measuring parts (cut edge part, center part, gingival edge part). A polishing operation was applied for 3 minutes for a total of 9 minutes. And the color tone of three color tone measurement parts was measured, and this measured value obtained by polishing for 3 minutes per site was used as data after polishing for 3 minutes. Further, the same polishing operation was repeated to measure the color tone at three color tone measuring portions, and the data was used as data after polishing for 6 minutes.

  In the polishing cleaning test, three polishing brushes of the same lot were prepared and named as Brush A, Brush B, and Brush C. And two bovine teeth for each test group per day according to the correspondence relationship of the sample polishing liquid, brush, and bovine teeth shown in Table 2 below so that the number of times each brush used for polishing is equalized for each test group A total of six were performed. Specifically, as shown in the numbers in parentheses in Table 2 below, the order of the test work is shown in the order of (1) → (2) → (3) → (4) → (5) → (6). When 6 polishing / color tone measurements have been made, the first day's polishing cleaning test is completed and the second day (polishing order (7) → (8) → (9) → (10) → (11) → ( 12)) On the third day (polishing order (13) → (14) → (15) → (16) → (17) → (18)), the same experiment was conducted, and a total of 18 samples were polished and toned. Was measured.

  The color tone of the tooth surfaces before staining, before polishing, after 3 minutes of polishing, and after 6 minutes of polishing were compared as follows.

That is, using a spectroscopic color difference meter (trade name: “Spectro colormeter SE2000”, manufactured by Nippon Denshoku Industries Co., Ltd.), the measured value of the color tone quantified in the L ^* a ^* b ^* color system was obtained. The L ^* a ^* b ^* color system is one of color models for digitizing color information, and is a color system standardized by the CIE (International Commission on Illumination). The color system consists of a lightness element (L ^* ) ranging from black to white, and two hue / color elements ranging from green to red (a ^* ) and from blue to yellow (b ^* ). It is known that it is possible to define a color space close to human vision.

  In addition, as shown in the middle row of the middle row of FIG. 1, the color tone measurement points are the tooth surface portions corresponding to the three intersections of the straight lines from the marks of the six horizontal edges and the two vertical edges of the bovine teeth ( Measure from the top (cutting edge, center, gingival margin) twice for each tooth, and the average value and standard value of the measured values (total of 12 measured values) from 6 bovine teeth in each test group Deviation was calculated.

FIG. 1 is a photograph showing the color tone change of the tooth surface of one of the six bovine teeth in each test group. When the upper stage is 20 wt% calcium hydrogen phosphate suspension (20% CaHPO ₄ ), the middle stage is the polishing detergent (20% cocoa) of Example 1 above, and the lower stage is distilled water as a sample polishing liquid. It is a photograph which shows the state of. The left column is a photograph showing the state after stain formation and before polishing, the middle column after polishing for 3 minutes, and the right column after polishing for 6 minutes.

As is apparent from FIG. 1, when polished with 20 wt% calcium hydrogen phosphate suspension (20% CaHPO ₄ ) or the polishing detergent of Example 1 (20% cocoa), it was polished with control distilled water. Compared to the case, it was clear from the naked eye that the stain in the polished portion was better removed.

In FIG. 2 (a)-(c), the result of the measurement by the said spectral color difference meter is shown with a graph. As described above, in the L ^* a ^* b ^* color system, the L ^* value indicates lightness, and the a ^* value and b ^* value indicate hue and saturation. Specifically, a ^* indicates the red direction, -a ^* indicates the green direction, b ^* indicates the yellow direction, and -b ^* indicates the blue direction.

  As shown in FIG. 2, by forming stain, the lightness of the teeth decreased (FIG. 2 (a)), and redness (FIG. 2 (b)) and yellowness (FIG. 2 (c)) became stronger. Moreover, the brightness is restored by polishing with the sample polishing liquid (FIG. 2 (a)), and redness (FIG. 2 (b)) and yellowness (FIG. 2 (c)) are closer to the color tone of the teeth before stain. The yellowness tended to be less likely to decrease than the redness.

  3 (a) to 3 (c) show the difference between the bovine teeth with respect to the degree of stain, and compare each of FIGS. 2 (a) to 2 (c) before and after polishing. It is a graph showing a measured value as the amount of change.

  As shown in FIG. 3, the brightness is significantly increased by polishing with the polishing detergent of Example 1 (20% cocoa) for 3 minutes as compared with polishing with distilled water (FIG. 3 (a)). Redness (FIG. 3 (b)) and yellowness (FIG. 2 (c)) were significantly reduced. Moreover, yellowishness further decreased by polishing for 6 minutes.

  From the above, it was revealed that the polishing detergent of Example 1 (20% cocoa) exhibited a significant polishing cleaning action. The effect was not inferior to that of calcium hydrogen phosphate which has been conventionally used as a polishing component.

Next, the amount of change (ΔL ^* , Δa ^* , Δb ^* ) before and after polishing of the L ^* value, a ^* value, and b ^* value shown in FIG. 3 is substituted into the following formula (1) to obtain L ^* a ^*. The overall color tone change amount color difference value ΔE ^* ab in the b ^* color system was determined. FIG. 4A shows the color difference values after polishing for 3 minutes, and FIG. 4B shows the color difference values after polishing for 6 minutes.

As shown in FIG. 4, it can be seen that by polishing for 3 minutes with the polishing detergent of Example 1 (20% cocoa), a significantly higher color difference value can be obtained compared to when polishing with distilled water (FIG. 4). 4 (a)). Further, in the polishing with the 20 wt% calcium hydrogen phosphate suspension (20% CaHPO ₄ ), an increase in color difference value was observed by polishing for 3 to 6 minutes, whereas the polishing of Example 1 above. In polishing with a detergent (20% cocoa), no increase in color difference value was observed due to polishing for 3 to 6 minutes (FIG. 4B). Therefore, according to the polishing with the polishing detergent (20% cocoa) of Example 1 above, dirt is effectively removed in a shorter time than the polishing with the 20 wt% calcium hydrogen phosphate suspension (20% CaHPO ₄ ). It was suggested that it could be dropped.

<Test Example 2>
In order to examine the presence or absence of cocoa stain formation, in the same manner as in Test Example 1 above, cocoa stain was formed on bovine teeth with a 4% by weight cocoa solution at a normal drinking concentration, and the color tone was changed to that of the tea solution stain. Compared. The results are shown in FIGS.

  As shown in FIG. 5, when bovine teeth were soaked in a 4% by weight cocoa solution, it was revealed that the change in color tone was significantly smaller than that of the black tea solution, and almost no stain was formed.

<Example 2>
A powder dentifrice was prepared by a conventional method at a blending ratio shown in Table 3 below to obtain a powder dentifrice containing 98.1% cocoa powder per solid content.

<Example 3>
A moisturized dentifrice was prepared by a conventional method at a blending ratio shown in Table 4 below to obtain a moisturized dentifrice containing 87.4% cocoa powder per solid content.

<Example 4>
A toothpaste was prepared by a conventional method at a blending ratio shown in Table 5 below to obtain a toothpaste containing 60.4% cocoa powder per solid content.

<Example 5>
A liquid dentifrice was prepared by a conventional method at a blending ratio shown in Table 6 below to obtain a liquid dentifrice containing 29.9% cocoa powder per solid content.

  The powder dentifrices, moisturizing dentifrices, toothpaste dentifrices, and liquid dentifrices prepared in Examples 2 to 5 were all dentifrices with excellent usability.

  The present invention provides a polishing detergent that can be used as a polishing component to be blended in dentifrices, facial cleansing foams, body soaps, dishwashing detergents, and the like.
