Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a composition for treating hair containing a fermented rice bran / soybean extract. The hair treatment composition of the present invention is suitably used as a treatment agent for moisturizing and protecting hair, as well as for improving perm efficiency in permanent waves and reducing unpleasant odors such as sulfur.

[0002]

2. Description of the Related Art Hair is mainly composed of keratin proteins. The polypeptides that make up the keratin protein contain cysteine as an amino acid,
By the disulfide bond between the cysteines, a plurality of keratin proteins are cross-linked and intertwined. For this reason, the hair is tough and elastic, and has the property of immediately returning to its original state even when a physical external force is applied. Moisture is contained in hair, and this moisture greatly affects the physical properties and feel of hair. That is, if the hair is damaged by a chemical treatment such as a permanent wave or dyeing or bleaching, or by ultraviolet rays, etc., the moisture in the hair is lost, resulting in the hair becoming dull or less glossy, resulting in impaired beauty. In addition, it is known that the strength also decreases.

[0003] In this manner, the hair is repaired by a chemical treatment such as a permanent wave or dyeing or bleaching, or by repairing a damaged portion of the hair due to ultraviolet rays or the like, or by giving the hair a gloss, smoothness, and elasticity, thereby improving the beauty of the hair. Conventionally, various treatment agents have been used to maintain the taste. As such treatment agents, protein hydrolysates such as hydrolyzed collagen, hydrolyzed keratin, and hydrolyzed silk have been conventionally known, but permanent waves, dyeing and decoloring are widely used to produce a beautiful self. Today, there is a demand for the development of a hair-friendly treatment agent that has better moisturizing properties and hair protection properties than conventional ones.

[0004] Further, as described above, hair is tough and elastic since keratin protein is disulfide (SS) cross-linked, and has the property of immediately returning to the original state even when a physical external force is applied. are doing. Therefore, conventionally, to produce beauty by making hair a predetermined shape,
A permanent wave is taking place. The permanent wave is performed as follows. That is, the waving hair is first bent around a suitable mold and then the disulfide bridge is reductively cleaved by applying a reducing agent to the hair. At a later time, the reducing agent is removed and the oxidizing agent is added to form a new disulfide bond between adjacent cysteine residues of the paired polypeptide chains.
As a result, a new disulfide bridge is formed at the place where the α-helix coil of the hair fiber is twisted or bent, so that the predetermined shape formed by the permanent wave can be maintained for a long period of time.

[0005] Since the permanent wave is performed to maintain a predetermined shape of hair for a long period of time,
The perm agent used for this purpose is required to be able to exhibit excellent wave forming power and wave holding power. In addition, thioglycolic acid or its salts (ammonium salt, monoethanolamine salt), glycerin monothioglycolate, thiolactic acid or its esters, and inorganic sulfite are usually used as the components of the permanent agent used in the permanent wave. ing. However, since these permanent agents contain a sulfur compound in particular as described above, there is a problem that an unpleasant odor mainly due to a sulfur component remains on hair after a permanent wave treatment.

On the other hand, a fermented rice bran / soybean extract obtained by inoculating a medium containing rice bran, soybeans and a carbon source with natto or Bacillus subtilis and fermenting and cultivating the same has various physiological functions. It is known. For example, an active oxygen removing action and an antioxidant action (JP-A-6-284872) and a blood alcohol concentration reducing action (JP-A-3-272657).
Japanese Patent Application Laid-Open No. H10-209, etc.). However, all uses of these fermented rice bran / soybean extracts have been studied only for their effects when administered in vivo, and their effects on the properties of hair when applied to hair are mentioned. Absent.

[0007]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has an excellent moisturizing effect and a hair protecting effect as compared with conventional treatment agents. An object of the present invention is to provide a hair treatment agent composition that exhibits excellent waving and holding effects and that can suppress unpleasant odors such as sulfur derived from a perm agent.

[0008]

The present inventors have conducted various studies on the physiological effects of the rice bran / soybean fermented extract, and as a result, the rice bran, which has been known to have antioxidant and active oxygen inhibitory effects, has been known. When the soybean fermented extract was added to the treatment agent, it showed a moisturizing effect superior to conventional treatment agents containing hydrolyzed collagen and hydrolyzed keratin, a hair protection effect, and excellent wave formation and permanent wave treatment. The present invention has been found to exhibit a holding effect and to be able to suppress unpleasant odors such as sulfur derived from a perm agent to a low level, thereby completing the present invention.

The hair treatment composition of the first invention is a fermented rice bran / soybean extract obtained by inoculating a medium containing rice bran, soybeans and a carbon source with Bacillus natto or Bacillus subtilis, and fermenting and culturing. It is characterized by containing. The “fermented rice bran / soybean extract” is an extract obtained by inoculating a medium containing rice bran, soybeans, and a carbon source with Bacillus natto or Bacillus subtilis, and fermenting and culturing. The above-mentioned "fermented rice bran / soybean extract" may be a liquid obtained by filtering a culture fermented liquid obtained by culturing, or a liquid obtained by post-treatment such as decolorization,
A concentrated solution obtained by concentrating this may be used. In addition, solids or powdered powders from which the solvent has been removed by a known method such as spray drying may be used.

The above-mentioned "rice bran" refers to rice germ, defatted rice germ, rice bran, defatted rice bran, etc. The "soybean" refers to defatted soybean, china flour, soy flour, soybean hus, and hydrolysis thereof. Refers to things. In addition, as the above-mentioned “carbon source”, commonly used ones can be used, and for example, one or more of glucose, dextrin, lactose, starch and the like can be used. Usually, the ratio of these additives is 1 to rice bran.
When it is 00 parts by weight, soybeans are 1 to 20 parts by weight, preferably 10 to 20 parts by weight, and the carbon source is 20 to 80 parts by weight, preferably 40 to 60 parts by weight. This is because when it is within these ranges, it is most preferable for the growth of bacteria. The “medium” is not particularly limited as long as it contains the rice bran, soybeans, and carbon source and is capable of growing Bacillus natto or Bacillus subtilis. Usually, it is a liquid medium, but it may be a solid medium. The above-mentioned "natto bacteria" and "Bacillus subtilis" are usually commercially available common natto bacteria and Bacillus subtilis. However, even if it is a mutant of Bacillus subtilis or Bacillus subtilis, which is obtained by natural or chemical substances such as nitrosoguanidine, X-rays, ultraviolet rays and the like and is mutated by mycological properties, the present invention Rice bran included
It can be used as long as it does not lose its ability to produce a fermented soybean extract.

[0011] The above-mentioned "fermentation culture" is usually carried out by aeration and stirring. About the conditions of this fermentation culture,
Although there is no particular limitation as long as the fermentation is performed, the pH is usually 7.5 to 10, preferably 8.5 to 10, and the culture temperature is about 40 to 45 ° C. When adjusting the pH of the medium, sodium bicarbonate or the like can be used as an alkaline agent. In addition, protease can be used as a medium material. This case is useful because the soybean peptide is further decomposed.

The solid content of the above-mentioned “fermented rice bran / soybean extract” is, as shown in the second invention, 0.005 parts by weight or more, preferably 100 parts by weight or more, based on 100 parts by weight of the hair treatment composition. 0.015 parts by weight or more, more preferably 0.015 parts by weight
-0.5 parts by weight, most preferably 0.025-0.05
Parts by weight. If the solid content of the rice bran / soybean fermented extract is less than 0.005 parts by weight, the effect of protecting hair, such as a treatment effect and a moisturizing effect, is undesirably reduced.

The rate of change of the water content at a relative humidity of 90% of the permanent-treated hair treated with the hair treatment compositions of the first and second inventions is determined by the test method described in the following examples. 60% or less, preferably 50%
% Or less, more preferably 45% or less, and the percentage change in water content at a relative humidity of 90% of perm-treated hair treated with a hair treatment composition not containing a rice bran / soybean fermented extract. On the other hand, it is at most 70%, preferably at most 60%, more preferably at most 55%. Furthermore, the cysteic acid content of the perm-treated hair treated with the hair treatment compositions of the first and second inventions was determined for the perm-treated hair only in the test method described in the following examples. It is not more than 80%, preferably not more than 75%, more preferably not more than 70%, based on the cysteic acid content. 90 to the cysteic acid content of the hair
%, Preferably 80% or less.

The hair treatment composition of the present invention can be used independently as a treatment agent, or can be previously added to a permanent agent or the like as an additive for various hair treatment agents. The composition for treating hair of the present invention contains the above-mentioned fermented rice bran / soybean extract as an essential component, but usually maintains the basic performance as a composition for treating hair (treatment agent, perm agent, etc.). In order to do so, various additives can be appropriately added as needed as long as the object of the present invention is not impaired. For example, surfactants such as alkyltrimethylammonium chloride, higher alcohols, esters, oils such as silicone oils, humectants such as glycerin, propylene glycol, and pyrrolidone carboxylic acid, and perm agents for increasing the reducing power of the reducing agent. Agents (basic amino acids such as ammonia, amino alcohol, arginine, morpholine, various carbonates, phosphates, sodium hydroxide, potassium hydroxide, etc.) and other various additives (protective agents [hydrolyzed collagen, hydrolyzed keratin, etc.] , Hydrolyzed silk, etc.), stabilizers, chelating agents, pH adjusters,
Coloring agents, thickeners (such as sodium alginate), preservatives (such as paraoxybenzoates, sorbic acids, etc.),
Perfume etc.) can also be added.

(3) Method for Testing Perm Agent (Example 2) Measurement / Evaluation of Wave Efficiency In order to evaluate the perm forming power of the perm agent of this example, it is most commonly used as a method for measuring the wave effect of the perm agent. As a test method, the Kilby method (DH Kirby, Pro
ceedings of the Scientific
c Section, 26, 12 [1956]), the wave effect of the perm agent of this example was evaluated.
After washing test hair (collected from the same person) having a length of 20 cm with a 5% sodium lauryl sulfate solution, rinsing it sufficiently with water, allowing it to dry naturally at room temperature, and drying the test hair, a set of 20 test hairs A bundle was formed, and the end near the hair root was fixed with an adhesive. The bristle bundle was set on the wave device shown in FIG. As shown in FIG. 6, the wave device 1 used in the second embodiment includes a wave forming unit 11, a hair bundle fixing unit 12, and a rod 13. The wave forming portion 11, the hair bundle fixing portion 12, and the rod 13 are all made of plastic.
The size of the wave device 1 is a rectangular parallelepiped shape having a length of 10 mm, a width of 70 mm, and a thickness of 6 mm, of which the wave forming portion 11 is 50 mm in width and the hair bundle fixing portion 12 is 10 mm in width. The rod 13 has a cylindrical shape of 3 mmφ, and the interval between adjacent rods (distance between centers of circles) is 6 mm.

The wave device in which the hair bundle was set was placed in a petri dish, and the test sample prepared in the above (1) was poured until the hair bundle was immersed. After leaving this at 25 ° C. for 5 minutes in a thermostat, the test sample was discarded, and then a commercially available perm agent (first agent) containing 15% of the test sample was poured until the hair bundle was immersed. And
The hair bundle was left in a thermostat at 25 ° C. for 15 minutes, washed with water, and then a commercially available perm agent (15%) containing 15% of a test sample.
Agent), and the mixture was similarly left at 25 ° C. for 15 minutes and thoroughly washed with water. This was used as a test group, and a control group using water instead of the test sample was used. Thereafter, the hair bundle was removed from the device, and the distance of the formed wave (the distance for five peaks) was measured, and the wave efficiency (%) was obtained by the following equation.
The results are shown in Table 3 below and FIG. Wave efficiency (%) = 100− [100 × (BA) /
(CA)] A: The distance between the first rod and the sixth rod of the instrument (constant depending on the instrument) B: The distance of the formed wave (distance of 5 peaks) C: B was straightened Time distance (constant depending on the instrument) The commercially available perm agent used this time (first agent and second agent)
Used a cold two-bath permanent agent ("Benezel Wave Perm" manufactured by Dariya Corporation) containing thioglycolate as an active ingredient.

Measurement / Evaluation of Wave Retention Rate The hair bundles of the test group and the control group, which were waved by the above treatment, were immersed in a 20% sodium lauryl sulfate solution and left in a thermostat at 60 ° C. for 1 hour (abuse) test). After washing with water, the distance of the retained wave (the distance of five peaks) was measured for the hair bundles of the test group and the control group, and the wave efficiency was calculated by the above equation.
The wave retention was determined by the following equation. The results are shown in Table 3 below and FIG. Wave retention (%) = 100 × D / ED D: Wave efficiency after abuse test (%) E: Wave efficiency before abuse test (%)

Measurement / Evaluation of Cold Odor The test hair treated in the same manner as described above was naturally dried at room temperature. 0.1 g of the test hair was placed in a measuring bottle for odor sensor, sealed, and allowed to stand at 25 ° C. for 60 minutes, followed by odor sensor (FRAGANCE SENSOR SF-1).
05, manufactured by Mutual Pharmaceutical Co., Ltd.), and the cold odor was evaluated by measuring the odor in the gas phase by a closed saturation method. Then, the test hair was stored at 25 ° C., and the measurement was continued for 10 days. The measurement results are shown in Table 4 below and FIG. Also,
At the same time, the cold odor was evaluated by a sensory test. The test was performed for 10 days after the perm treatment, and the test hair was 25
Stored at ° C. The inspection was performed by 10 persons, and the odor intensity was indicated by the evaluation points as described below. Table 5 shows the measurement results (the number of persons indicating the evaluation points), and FIG. 5 shows the total of the evaluation points. Odor intensity Evaluation points Odorless 1 Smell that can be detected at last 2 Smell to be able to judge the type of odor 3 Smell that can be detected well 4 Strong odor 5

(4) Effects of the Embodiment If the hair is damaged, the moisture holding capacity of the hair is reduced, and as a result, the change in the moisture in the hair due to the change in the environment is increased. That is, in a dry environment, the amount of moisture in the hair is reduced, resulting in dry and dry hair, and in a humid environment, the amount of moisture in the hair is excessive, resulting in hair lacking elasticity. Therefore, a change in moisture in hair due to a change in moisture in the environment is a criterion for evaluating damage to hair. From Table 1 and FIG. 1, when the control group treated with the conventionally used hydrolyzed keratin-containing treatment agent and the test group combined with the rice bran / soybean fermented extract were compared, the relative humidity was found to be lower in the control group. When the ratio changes from 20% to 90%, the water content in the hair increases by about 83%, whereas in the test group, the increase is only about 41%, indicating that the change in the water content is small. From these results, in the test group treated with the treatment agent to which the rice bran / soybean fermented extract was added, drying in a low-humidity environment and absorption of water in a high-humidity environment were suppressed. It can be seen that the change in water in the inside was small, and the water retention ability by the treatment agent was enhanced.

Disulfide bond (S
If the restoration of —S bond) is incomplete, the SH group is oxidized to become an SO ₃ H group, and cysteic acid is generated. As a result, the structure of the hair is broken, and hair components are easily eluted, resulting in damage. Therefore, the cysteic acid content in the hair is a criterion for evaluating the damage of the hair. From Table 2 and FIG. 2, the cysteic acid content of the permed hair was 2
88 μmol / g and perm-untreated hair (172 μm
ol / g). And, in the control group treated with the conventionally used treatment agent containing hydrolyzed keratin, 243 μmol was used.
/ G, and a decrease of about 17% as compared to the hair subjected to the permanent treatment. On the other hand, in the test group in which the rice bran / soybean fermented extract was used in combination, the value was 186 μmol / g, which was almost the same as that of the untreated perm, and decreased by about 37% compared to the hair treated with the perm. In addition, it can be seen that it is reduced by about 24% as compared with the control group. As described above, by adding the fermented rice bran / soybean extract of the present example to the treatment agent, the effect of inhibiting the production of cysteic acid by the hydrolyzed keratin was enhanced, and the hair was almost restored to the untreated hair. You can see that.

From Table 3 and FIG. 3, comparing the wave efficiency of the control group and the test group, the wave efficiency of the test group was 65%.
And about 26% larger than the control group (51.7%). The high wave efficiency indicates that the distance of the formed wave (the distance of five peaks) is small, that is, the effect as a permanent agent is strong. When the wave retention of the control group and the test group was compared, the wave retention of the test group was 79.8%, and the control group (68.2%)
17% larger than that of FIG. A large wave retention ratio indicates that the wave effect after the abuse test is large relative to the wave effect before the abuse test, that is, the wave shape is maintained even after the abuse test. From the above, it can be seen that by using the rice bran / soybean fermented extract in combination with the perm, a wave can be efficiently formed in the perm treatment, and the shape of the formed wave can be maintained.

From Table 4 and FIG. 4, comparing the control group and the test group for the cold odor after the perm treatment measured by the odor sensor, the control group showed a higher measured value from the time of the perm treatment, and the number of days passed. Also, it can be seen that the rate of reduction in cold odor is small, and it takes 6 days for the measured value to reach a steady state. On the other hand, in the test group, the measured value was low from the time of the permanent treatment, and the rate of reduction of the cold odor was large, indicating that the measured value had already reached the steady state after 3 days. Further, from Table 5 and FIG. 5, when the control group and the test group were compared for the cold odor after the perm treatment by the sensory test, the same tendency as in Table 4 and FIG. 4 was found. That is, in the control group, the evaluation points (total value) are high from the time of the perm treatment, and the reduction rate of the cold odor is small even after the lapse of the number of days. (2 or less) takes 6 days. On the other hand, in the test group, the evaluation points (total value) were low since the perm treatment,
It can be seen that the rate of reduction in cold odor is large, and after three days, more than half of the people have already evaluated that they do not feel much cold odor. From the above, it can be seen that when the rice bran / soybean fermented extract is used in combination with the perm, the cold smell mainly derived from the sulfur component of the perm can be suppressed.

The present invention is not limited to the specific embodiments described above, but may be variously modified within the scope of the present invention in accordance with the purpose and application. That is,
The rice bran / soybean fermented extract contained in the hair treatment composition of the present invention is added separately to a treatment agent or a perm agent in advance, and is separately prepared in the form of a powder, a concentrate or an aqueous solution. At the time of use, a rice bran / soybean fermented extract may be added to and mixed with a treatment agent or a perm agent.

[0034]

EFFECTS OF THE INVENTION According to the hair treatment compositions of the first and second inventions, the combined use of rice bran and soybean fermented extract is superior to conventional treatment agents and perm agents. It exhibits a moisturizing effect and a hair protecting effect, and exhibits excellent wave forming and holding effects in permanent wave treatment, and can suppress unpleasant odors such as sulfur derived from a permanent agent. As a result, it can be suitably used as various hair treatment agents such as treatment agents and perm agents.
