Description

  The present invention relates to a hair restorer, and more particularly to a hair restorer containing a humus extract.

  It is known that hair growth occurs by proliferation and differentiation of hair matrix cells and is regulated by hair papilla cells (Non-patent Document 1). The dermal papilla, which is an aggregate of dermal papilla cells, grows greatly during the growth phase of the hair. Therefore, it is considered that the proliferation of dermal papilla cells plays an important role in forming thick and firm hair.

  The increase in dermal papilla cells is a type of male hormone that is promoted by cell growth factors such as EGF and FGF, and is considered to suppress the production of dihydrotestosterone (DHT), which is known as a cell growth inhibitor in animal studies. It is done. Therefore, conventionally, methods for activating cell growth factors such as EGF and FGF, methods for suppressing cell growth inhibitors such as DHT, and the like have been studied as methods for promoting hair growth. Finasteride, which is known as an antiandrogen used as a positive control in Examples described later, is more effective as a 5α-reductase inhibitor than EGF or FGF production promotion. It is thought to be involved in the androgen receptor contained in the papillary cells and showed cell proliferation. Minoxidil also appears to have a similar mechanism of action as finasteride.

  Patent Document 1 discloses a hair growth agent characterized by containing a humus soil extract. According to Patent Document 1, it is said that it is possible to provide a hair restorer that is gentle to the human body and that has an excellent feeling of use and a moisturizing effect. Patent Document 2 discloses that a hair thickener and a hair restorer are produced using an aqueous liquid containing a humus extract material. The humus soil extract used in the examples of Patent Document 1 and Patent Document 2 is an extract of humus soil collected from Kara Nishina, Moriyama-machi, Kitakaku-gun, Nagasaki Prefecture. This humus soil extract is contained in the commercially available hair restorer used in Comparative Example 2 described later.

JP 2006-327978 (hair restorer) Patent No. 3507347 (humus soil extractable aqueous solution)

  In general, humus is a fertilized soil containing many nutrients approximately 100 million years old that remains as organic matter without being transformed into oil or coal. More specifically, when the plant that inhabited the period entered the ice age, it was buried underground, changed to peat moss by microorganisms such as bacteria, and new organic matter accumulated on top of it, and again decomposed by bacteria etc. A deposited layer is formed as the process proceeds. Humus is an amorphous organic polymer such as fulvic acid or humic acid, which is formed by the decomposition of carbohydrates and proteins in plant residues and microbial remains in the soil by microorganisms, and the decomposition products are condensed. Contains minerals. Humic acid is a red-brown or black-brown amorphous high-molecular organic acid that is soluble in alkali and insoluble in acid, and fulvic acid is an amorphous high-molecular organic acid that is soluble in alkali and acid.

  Amorphous polymeric organic acids such as fulvic acid and humic acid vary depending on factors such as the soil of the humus production area and the age of its generation. The effect of humus is also considered to change due to the difference in the structure and physical properties of the amorphous polymer organic acid.

  Then, the subject of this invention is providing the hair restoring agent which contains humus extract substance and was excellent in the hair growth effect | action.

As a result of intensive studies on the above problems, the inventor of the present invention has hitherto been known to have a hair growth action like finasteride on a fulvic acid having a structure based on specific infrared absorption among fulvic acids having various molecular structures and substituents. Furthermore, the present invention was completed by discovering that it exhibited an excellent hair growth action even when compared with a conventionally known humus extract-containing hair restorer. That is, the present invention provides an effective amount of a humus extract containing fulvic acid having infrared absorption peaks at wave numbers 3362, 2875, 1675, 1559, 1360, 1200, 1047 and 835 cm ⁻¹ in the infrared absorption spectrum in the FT-IR method. And a hair restorer comprising cosmetic, dermatological and / or pharmaceutically acceptable additives or food additives. In the present specification, the “hair growth agent” is used in the meaning including a hair growth effect in addition to the hair growth effect.

  More specifically, the humus extract contains fulvic acid having an infrared absorption spectrum shown in FIG.

  It is preferable that the said humus extract does not have a naphthalene ring structure.

  The average molecular weight of the fulvic acid in the humus extract is preferably less than 4,000.

  The hair restorer of the present invention is for example for transdermal administration.

  The form of the hair growth agent for transdermal administration is, for example, a liquid agent, a liquid agent, an emulsion, an emulsion, an emulsion, a cream, a powder, or a clay pack.

  The hair restorer of the present invention is for oral administration, for example.

  Examples of the hair-restoring agent for oral administration are powders, granules, capsules, pills, tablets, chewable tablets, drops, liquids, syrups, or drinks.

  According to the hair restorer of the present invention, which contains a humus extract containing a fulvic acid defined by a specific infrared absorption wavelength, the hair restoring action is exerted like finasteride, and its effect is humus It is significantly higher than known humic substance-containing hair restorers containing extracts.

It is a figure of the FT-IR absorption spectrum based on the ATR method of the fulvic acid fraction of the humus extract (product name: Humicle (trademark)) used in Example 1. FIG. It is a FT-IR absorption spectrum figure based on the ATR method of the standard fulvic acid and the standard humic acid of Danto used in Comparative Example 3. 2 is a three-dimensional fluorescence spectrum diagram of a 4% aqueous solution of humus extract used in Example 1. FIG. It is a three-dimensional fluorescence spectrum figure of the aqueous solution (concentration 10 microgram / mL) of the terraced fulvic acid used in the comparative example 3, and the aqueous solution (concentration 10 microgram / mL) of the terraced humic acid. In Example 1 and Comparative Examples 1-4, it is the figure which plotted the density | concentration (logarithmic scale) of the humus extract to the X-axis, and the proliferation rate of the human hair papilla cell to the Y-axis. A growth rate of 100% means a control (no test article added). From FIG. 5, the hair restorer of the present invention (Example 1) is an artificially synthesized fulvic acid product (Comparative Example 1), an existing hair restorer product (Comparative Example 2) or a humus extract containing a humus extract. It can be seen that the hair papilla cell proliferation rate is higher than that of the standard product (Comparative Examples 3 and 4).

Hereinafter, embodiments of the present invention will be described in detail. The hair restorer of the present invention effectively uses a humus extract containing fulvic acid having infrared absorption peaks at wave numbers 3362, 2875, 1675, 1559, 1360, 1200, 1047 and 835 cm ⁻¹ in the infrared absorption spectrum in the FT-IR method. Including quantity.

  In the hair restorer of this invention, it is essential to use the humus extract which has the above-mentioned specific infrared absorption peak among humus extracts. A humus extract will not ask | require the origin, if it has said infrared absorption characteristic.

  By mixing the humus containing the humus extract having the infrared absorption peak with water (for example, distilled water, ion exchange water, reverse osmotic pressure water, etc.), the humus extract is extracted into the water. In that case, humus is normally mixed in 5-35 weight part with respect to 100 weight part of water, Preferably it is 15-25 weight part, Most preferably, it is a ratio of 17-18 weight part. The mixture is left at room temperature, usually for 24 to 96 hours, preferably 48 to 72 hours. During the standing, the mixture may be appropriately stirred. Next, the supernatant or filtrate of the above mixture is used as a humus extract. The pH of the liquid humus extract is usually 3.0. This liquid humus extract may be dried to a powder.

  The average molecular weight of the fulvic acid in the humus extract is usually less than 4,000, preferably 3,500 or less, particularly preferably 3,000 or less, more preferably 3,000 to 1, 000.

  The humus extract may be commercially available, and is available in Japan under the product name “Humicle (registered trademark) HC fulvic acid powder” from, for example, Style and Value Japan. Table 1 shows the component analysis results (content in the sample wet weight).

  From the results of the total organic carbon (TOC) measurement of the 4% aqueous solution of Humicle and the total organic carbon (TOC) measurement of the fulvic acid fraction, almost all of the carbon in the Humicle is occupied by organic carbon, and the organic carbon It was confirmed that almost the entire amount constituted fulvic acid. The fulvic acid content in the fumicle was estimated to be about 3%.

  Fulvic acid was fractionated by extracting the fumaric alkali (0.1N sodium hydroxide) and acid (hydrochloric acid, pH 2) soluble components. The physical property test method and analysis results of the fumicle or fulvic acid fraction are shown below.

(1) Three-dimensional spectrofluorimetry The three-dimensional excitation-fluorescence spectrum (measuring device JASCO FP-8200) of a 4% aqueous solution of Humicle is shown in FIG. For comparison, fulvic acid and humic acid extracted and refined from Danto forest soil in Aichi Prefecture (both are distributed as “Standard Material of the Japanese Humic Society” by the Japanese Humic Society, respectively) FIG. 4 shows three-dimensional fluorescence spectra of fulvic acid and corrugated humic acid. In the three-dimensional excitation-fluorescence spectrum of Humicle and Danto's fulvic acid, there are peaks of excitation around 250 nm-fluorescence near 430 nm and excitation around 320 nm-fluorescence near 430 nm, which are characteristic of fluorescence derived from fulvic acid. ing.

(2) GPC-UV / TC analysis The GPC-UV / TC analysis method separates dissolved organic substances in water at high speed according to the size of molecules and the degree of exclusion, and separates the separated dissolved molecules into a UV detector and a TC detector (Total Carbon). (Analyzer) is a monitoring method. The following GPC-TC device:
GPC: Shodex GPC SYSTEM 21
Separation column TOSO HW-50S
Eluent 30 mM Na ₂ HPO ₄
UV absorption (220 nm) detector: GL7450 (manufactured by GL Sciences)
TC detector: LCT-100 (manufactured by Toray Engineering)
Was used to measure the molecular weights of the fumicle and the fulvic acid from Dando.

  In both TC chromatograms, the peak position of Danfu fulvic acid was 51 minutes, whereas it was 54 minutes for the 4% humicule solution. When the retention time at the peak position is converted into the exclusion characteristics of the polysaccharide and PEG (polyethylene glycol) of the separation column used, the molecular weight of the terraced fulvic acid is about 4,000, and the molecular weight of the organic matter in the Humicle solution Was estimated to be about 1,000 to 3,000.

  TC output value (mV) at the retention time at the peak top, output value (mV) at UV (220 nm) absorption, and UV output value / TC output value (intensity of UV absorption per unit organic substance amount (carbon amount)) The results are shown in Table 2.

  From Table 2, the UV / TC value of the Humicle solution is nearly similar to that of the Danto fulvic acid solution. The similarity in ultraviolet absorption (220 nm) derived from the molecular structure of organic matter indicates that there is similarity in the skeleton and functional group types of both molecular structures.

(3) Fourier transform infrared spectrophotometer method (FT-IR)
An infrared absorption spectrum was obtained by the ATR method (Attenuated Total Reflection, total reflection absorption method) of the fulvic acid fraction. Specifically, the fulvic acid fraction was applied to Dax-8 resin (manufactured by Spelco), and the organic matter adsorbed thereon was desorbed with an alkaline solution. The desorbed organic substance was further passed through an ion exchange resin to remove unnecessary salts. The obtained sample was subjected to FT-IR spectroscopic analysis (PerkinElmer Spectrum 65) based on the ATR method.

  FIG. 1 shows an infrared absorption spectrum of fulvic acid contained in the humus extract (humicicle). For comparison, FIG. 2 shows infrared absorption spectra of fulvic acid and humic acid produced in Danto. Major infrared absorption peaks were extracted from FIG. 1 (Humicle) and FIG. 2 (Stepbo fulvic acid), and the results are shown in Table 3 in terms of wave number.

The fulvic acid contained in the fumicle and the fulvic acid produced from the terraced house have a carboxyl group (CO) absorption peak at 1200 cm ⁻¹ in common, but the level of the humicule is higher than that of the fulvic acid produced from the terraced house. small. That fulvic acid in Hyumikuru is clearly different spectrum of Danto producing fulvic acids are 1559,1047 and tri-substituted benzene type signals were observed at 835 cm ^-1, and phenol or an alcohol type 3362 and 1360 cm ^-1 Is observed.

  The results of infrared spectroscopic analysis suggest that the fulvic acid in the humicle has fewer carboxyl groups than the dansted fulvic acid, and has more trisubstituted benzene type phenolic compounds. Although not intended to limit the invention, it is considered that this difference in molecular structure is reflected in a difference in the proliferation rate of hair papilla cells as shown in Examples and Comparative Examples described later. That is, the hair restorer to which an effective amount of a humus extract containing fulvic acid having the specific infrared absorption spectrum characteristic specified in the present invention is added has an effect superior to that of a conventional hair restorer containing humic substances. .

  Hereinafter, the present invention will be described in more detail by showing Examples and Comparative Examples of the present invention. However, the present invention is not limited to the following examples.

[Example 1, Comparative Examples 1 to 4]
Whether or not the hair-restoring agent of the present invention has a hair-growing action was examined by a hair papilla cell proliferation effect test (in vitro), which is an experimental model system for hair papilla cells. Specifically, the hair growth agent of the present invention was added to the hair papilla cells, the cell growth promotion rate of the hair papilla cells was measured by MTT assay, and the hair papilla cell growth rate was calculated.

1. Preparation of Hair Growth Agent Test Product As Example 1, a humus extract product “Humicle” (manufactured by Style and Value Japan Co., Ltd.) obtained by drying an aqueous extract of humus produced in Utah, USA was prepared. The physical properties of the fulvic acid fraction contained in the vehicle are as described above.

As a positive control for evaluating the effect of the hair restorer of the present invention, finasteride, which has been conventionally known for its hair restoring action, was prepared. As a control (negative control), a medium (no test product added) was employed. Furthermore, in order to compare the hair-restoring agent containing the humic substance which does not satisfy | fill this invention, and the hair-restoring agent of this invention, the product containing the humus extract shown below and the standard fulvic acid were prepared.
Comparative Example 1: 100% fulvic acid obtained by fermentation of fruits and plants, health drink manufactured by M Company Comparative Example 2: Company N containing humus extract (fulvic acid) from Karabi, Moriyama-cho, Kitakagi-gun, Nagasaki Prefecture Soft drink comparative example 3: Danto fulvic acid (humic acid reference material, manufactured by Japanese Society of Humic Substances)
Comparative example 4: Lake Biwa fulvic acid (humic acid reference material, manufactured by Japanese Humic Society)

2. Basic culture of human hair papilla cells Human hair papilla cells (manufactured by Takara Bio Inc.) were used as test cells. In a culture flask (culture area 75 cm ² ), the human hair dermal papilla cell culture medium and the human hair dermal papilla cell suspension are adjusted to a final concentration of 2.5 × 10 ⁴ cells / mL in the culture solution and a total volume of 10 mL. The cells were added and cultured in a CO ₂ incubator (37 ° C., CO ₂ 5%) for 7 days to ensure the necessary number of cells.

3. Preparation of test article solution The hair growth agent test articles of Example 1 and Comparative Examples 1 to 4, respectively, had a test article concentration of 125, 31.25, 7.81, 1.95, 0.48, or 0.12 μg / Diluted sequentially with hair papilla cell culture medium to a volume of ml. The positive control Finasteride was diluted to 3 ng / mL.

4). 4. Cell Proliferation Evaluation Test 4.1 Culture of human hair dermal papilla cells Cultured human hair dermal papilla cells were collected from the culture flask by trypsin treatment, and the number of cells was counted. Cells were suspended in a hair papilla cell medium to prepare a cell suspension having a cell concentration of 1 × 10 ⁴ cells / mL. 0.2 mL of the prepared cell suspension was added to each well on a test plate (96 well micro plate), and allowed to stand at room temperature for 20 minutes. Pre-cultured for 18 hours in a CO ₂ incubator (37 ° C., CO ₂ 5%). After the preculture, the medium in each well of the test plate was replaced with the prepared test solution, and further cultured in a CO ₂ incubator (37 ° C., CO ₂ 5%) for 72 hours. After 72 hours, viability was confirmed by MTT assay. * Test results were calculated three times independently.

4.2 MTT assay The medium of the plate after completion of the culture was discarded, and 0.1 mL of MTT reagent-containing medium (1 mg MTT / mL medium) was newly added to each well. The color reaction was performed by culturing in a CO ₂ incubator (37 ° C., CO ₂ 5%) for 3 hours. MTT solubilized solution (isopropanol) was added to each well in an amount of 0.1 mL to extract MTT taken up by living cells. The absorbance of the MTT extract was measured at 570 nm using a microplate reader. As shown in the following formula, the cell growth rate was calculated as a percentage when the absorbance of the control (untreated cells of the test product) was 100.

4.3 Test data and statistical analysis An analysis of variance was performed on the obtained data. When equal variance was confirmed, an uncorresponding t-test was performed as a statistical analysis, and a comparison with a control group was performed. The test results are shown in Table 4 and FIG.

  Finasteride at a concentration (3 ng / ml), which is a positive control, showed a hair papillary cell proliferation rate of 106.8 ± 0.6% relative to the control (cell growth rate 100%), confirming hair papillary cell increasing activity. It was done.

  On the other hand, the hair restorer of the present invention (Example 1) showed a cell growth rate of 107.4 to 116.2% at a concentration of 0.48 to 125 μg / ml. In particular, the dermal papilla cell proliferation rate of 116.2% at a concentration of 1.95 μg / ml in Example 1 showed 1.09 times (= 116.2 / 106.8) greater proliferation activity than the positive control. .

  Next, Comparative Example 3 (stepped acid fulvic acid) and Comparative Example 4 (Lake Lake acid) are fulvic acids that are standard products of the Japanese Humic Society. When Comparative Examples 3 and 4 were compared with Example 1, Comparatives 3 and 4 showed a tendency similar to Example 1 at a fulvic acid concentration of 0.48 to 125 μg / ml, but the cell growth rate was 99.99. 8-106.7% (Comparative Example 3) and 96.4-102.7% (Comparative Example 4), inferior to Example 1.

  Comparative Example 1 is a fulvic acid artificially synthesized using fruits and plants as starting materials, unlike the humus extract used in the present invention. Comparative Example 2 is presumed to be a humus extract produced in Karabi, Moriyama-cho, Moritaka-machi, Kitakagi-gun, Nagasaki Prefecture, which was used in Examples of Patent Documents 1 and 2. When these Comparative Examples 1 and 2 are compared with Example 1, the cell growth rates of Comparative Examples 1 and 2 are 86.1 to 104.4% and 94.2 to 101.2%, respectively. Obviously inferior to 1.

  From the above results, the hair restorer of the present invention containing a specific humus extract is more effective than finasteride, a humus extract standard product, and an existing hair restorer product containing a humus extract, which are known to have hair papilla cell proliferation activity. It was found to have high hair papilla cell proliferation activity. Accordingly, the hair growth agent of the present invention is expected to be industrially useful as a hair growth agent having an excellent hair growth action.
