【産業上の利用分野】
本発明は、玄米を精米(100〜92%)した際に生じる糠を原料として得られる化粧料に関するものである。
【0002】
【従来の技術】
化粧品関係における糠の利用については、糠そのものの利用に糠袋があり、古来より美容的用途に使われている。糠を原料としたものについては、アルコール抽出したもの(特開昭59−154971)、米糠または米糠を水あるいはアルコール抽出したエキスを含有する貼布剤(特開平4−368314)、また、米糠から単離した多糖類(特公平1−49688)の美容用途としての利用が提案されている。
【0003】
【発明が解決しようとする課題】
米糠の美容的効果を高めるためには、米糠中の有効成分が皮膚から吸収されることが重要な要件と考えられるが、米糠の主要成分は、でんぷん、蛋白質、脂肪など分子量の大きいもので、これらが直接吸収されるのはむつかしいことである。
本発明は、人体に対し安全で、肌に対しベトツキがなく、米糠の持つ有効成分をより効果的に皮膚から吸収しやすいものにすることによって、美容効果を高めることを目的とするものである。
【0004】
【課題を解決するための手段】
本発明者らは、動植物合和すの観点から、主食である米を中心に種々の植物成分の研究を進めてきた。その過程で、米糠について鋭意検討を重ねた結果、下記の処理を行うことによって、保湿効果、つるつる効果および肌のキメを細かくする効果、があることを見出し、本発明を完成するに至った。
▲1▼ 米糠の加水物を酵素分解または麹を作用させる。
▲2▼ 米糠を抽出する。
▲3▼ 米糠を抽出するに当たり、その抽出前、抽出と同時または抽出後に酵素分解または麹を作用させる。
▲4▼ 米糠の加水物を酵素分解または麹を作用させた後、さらにアルコール発酵を行う。
▲5▼ 米糠を抽出するに当たり、その抽出前、抽出と同時または抽出後に酵素分解または麹を作用させた後、さらにアルコール発酵を行う。
【0005】
以下、本発明について詳細に説明する。
米糠は玄米を92%精白するときに得られるものであり、その玄米は品種、種類を問わない。原料処理においては、蒸煮、焙煎(砂焙り、網焙り、熱風焙煎等全てを指す)、蒸煮焙煎、凍結乾燥等の表面変性、UV照射等の光変性、パットライス等の加圧焙煎、揚げる等の原料処理をしてもよく、また、効果も変ることはない。
【0006】
米糠を酵素分解する場合、まず、米糠に加水した後、酵素を添加する。加水量は、収率、作業性、最終使用目的などに応じて適宜選定する。また、加水温度は、酵素あるいは麹の至適温度が効率的であるが、低温でも長時間おけば酵素分解は充分に行われる。ただし、40℃以下の低温の場合は、なんらかの防腐を行うことが必要である。また、分解さえすれば温度は高温でもよい。分解時間は、分解さえ行われれば短くても長くてもよい。すなわち、分解さえ行われれば本効果を有するエキスが得られる。 ここで使用する酵素は、澱粉分解酵素、蛋白分解酵素および脂肪分解酵素であり、これらの酵素のうち1種または2種以上を用いる。また、麹を使用する場合においては、加水量、作用温度、作用時間は、酵素分解の場合と同様に行なう。使用する麹は、一般に使用される麹を使用すればよく、麹菌の種類および品種は問わない。
【0007】
米糠を抽出する場合、抽出温度は高温が効率的であるが、低温でも十分に抽出することができる。ただし、40℃以下の低温の場合は、pHを酸性あるいはアルカリ性にするか、防腐剤あるいはアルコールを加えて、米糠が腐敗しないように処理することが望ましい。抽出時間は、有効成分さえ抽出できれば長くても短かくてもよく、抽出温度により定めればよい。また、抽出は、加圧下または常圧下で行っても、減圧下で行ってもよい。
【0008】
水抽出の場合、最も問題になるのは糊化現象である。糊状になれば抽出効率が悪くなるばかりでなく、実作業においては困難を極める。これを防ぐためには、アミラーゼを加えて反応させるか、塩酸などで酸性にして澱粉を切ってやればよく、この方法を用いることにより、十分に解決でき、実用上も全く問題はない。
抽出物中の有効成分は、酸、アルカリに安定であるためか、酸分解抽出あるいはアルカリ分解抽出を行うのも有効である。この場合、必要により中和、脱塩を行う。
【0009】
有機溶媒で抽出を行うことも有効である。有機溶媒はアルコール、アセトン、n−ヘキサン、メタノール等の一般的な有機溶媒でよいが、人体に対して有害なものは、抽出後、溶媒を完全に除去する必要があるので安全なものがよい。
抽出を行うに当たり、その抽出前、抽出と同時、または抽出後に酵素分解または麹を作用させると効果的である。
ここで、抽出と同時に酵素分解あるいは麹を作用させる場合、具体的には、有機溶媒中で酵素分解あるいは麹を作用させるか、減圧抽出下で酵素分解あるいは麹を作用させるなどの方法により行う。
本発明においては、上記の各処理を行うと同時または処理後、アルコール発酵を行えば、さらに有効である。
【0010】
このアルコール発酵を行う場合、上記のようにして得られた抽出物、酵素分解物(酵素分解、抽出を組み合わせて得られるものも含む)、また、麹を作用させたものをそのまま、あるいは圧搾、濾過して得た液をアルコール発酵させる。酵素分解とアルコール発酵とを同時に行ってもよい。すなわち、米糠に加水後、酵素または麹、さらに酒母または酵母を添加して、糖化、アルコール発酵を同時に行う。澱粉分解酵素または麹を使用しないものにおいては、補糖をすればよい。大量に製造する場合、糖化と発酵のバランスを考えながら、清酒醸造に準じて3段階あるいは何段階にも分けて、米糠を添加するのが望ましい。特に少量を処理する場合においては、一度に添加するのが有効である。糖化およびアルコール発酵は約10〜24日間行い、この際、腐敗が心配な場合は、酸を添加するか、発酵の阻害にならない適当な防腐を施す。
【0011】
なお、アルコール発酵を行うと、ベトツキがなくなること、濃縮がしやすく有効成分の濃縮が容易になることなどの利点もある。
以上のようにして得られる本発明品は、残渣を分離することなくそのまま、あるいは圧搾、濾過して用いる。そのまま用いるときは、殺菌あるいは除菌して製品にする。なお、本発明品を配合する場合、実際の用途に応じて常法にしたがって、クリーム、洗顔料、乳液、化粧水、クレンジング、パック、石鹸などの化粧料のような剤型にする。他の配合成分は、通常用いられるものいずれでもよく、さらに、他の薬効剤を併用してもよい。
【0012】
次に、本発明品の効果を調べるために行った試験とその結果について説明する。
試験例1
皮膚のしなやかさやなめらかさを決める大きな要因に、皮膚表層の角層の水分含有量がある。そこで、それを高周波伝導度測定装置で測定した。
【0013】
パネラー5名の前腕届側4×4cmに、20mlの本発明品を塗布する前と塗布2時間後における角層水負荷試験を行って、角層の水分含有量および水分保持能がどのように変化したかを調べた。
角層水負荷試験の方法は、田上らの方法によった。すなわち、本発明品を塗布する前腕届側の4×4cmの場所内の任意の3ケ所を決め、その場所をボールペンでしるしをしておく。
はじめはその場所の水分含有量を測定する。その後、10秒間蒸留水を1滴その部に置き、水滴をガーゼでよくふきとった直後の測定値、次いで30秒毎に2分間測定を行い、吸収された水分が失われてゆく状態より、その角層の水分保持能を調べる。
水分保持能は以下のように吸収された水分が保たれる割合を百分率に算出して表わす。
【0014】
【数1】
【0015】
次いで、本発明品を塗布し、塗布2時間後、塗布前に測定した場所において、角層水負荷試験を行った。測定は温度20℃、相対湿度40%に設定した室でパネラーは測定の30分前に入室し、安静状態で測定した。結果を表1に示す。
【0016】
【表1】
【0017】
表1に示したように、本発明品はいずれも対照の水と比較して、塗布後、水分含有量が増加し、水分保持能も高くなり、保湿効果が示された。特に実施例5および9〜13においては、保湿剤として用いられている0.2%ヒアルロン酸ナトリウムと比較して、より高い保湿効果を有していることが示された。
【0018】
試験例2
実施例13で得た本発明品を、下記に示すような化粧水に剤型化したときの効果について調べた。
化粧水は次の処方により作製した。
実施例13で得た本発明品 20.0(重量%)
ソルビトール 3.0
グリセリン 5.0
精製水 66.4
アラントイン 0.1
ポリオキシエチレンヒマシ油誘導体 0.5
エタノール 5.0
試験方法は、パネラー10名(女性)の右頬に本発明品を配合した化粧水を、左頬に本発明品を精製水に置きかえたブランク用化粧水を1日2回、1カ月間塗布し、塗布前後の水分含有量および水分保持能を試験例1と同様の方法で調べた。結果を表2に示す。
【0019】
【表2】
【0020】
表2に示すとおり、本発明品を配合した化粧水において、1カ月間の塗布前後で、ブランク化粧水のそれと比較し、明らかに水分含有量が増加し、また、水分保持能も高くなっていることが分かった。
さらに、官能評価をアンケート調査したが、パネラー全員が、本発明品を配合した化粧水の方が肌がしっとりし、みずみずしさが増し、化粧ののりがよくなった。と答えた。なお、肌荒れなどトラブルは1名もなかった。
【0021】
このように、特に酵素分解抽出し、アルコール発酵を行ったものについて保湿効果が高かったが、それについて成分を調べると、アミノ酸度(滴定アミノ酸度)が12.4と非常に高い値であることが分った。アミノ酸類は天然の保湿因子であることが知られている。また、米糠には脂肪が約17%含まれているが、これがリパーゼにより脂肪酸とグリセリンに分解される。これらの脂肪酸およびグリセリンも保湿に関係していることが考えられる。
【0022】
なお、糖類は発酵によって酵母に消費され、直糖として0.9%であった。また、アルコールを加え、アルコール濃度を70%程度にしても白色沈澱が生成されなかったことから、多糖類もないことが分かった。
試験例3
肌のつるつる効果、さらに肌のキメが細かくなる効果を動摩擦計による測定で調べた。
【0023】
被験者15名で右前腕部届側に1カ月間、1日2回塗布し、塗布前後の変動係数(MMD)および摩擦係数(MIU)を測定した。対照は左腕の同部位で行った。測定条件は以下のとおりである。
温度 25℃
湿度 60%
使用センサー KES−SE摩擦感テスターSE−2タイプ(0.5mmピアノワイヤー使用)
摩擦静荷重 50gf
測定速度 1mm/sec
測定距離 30mm(積分有効範囲20mm)
結果を表3に被験者15名の平均値で示す。
【0024】
【表3】
【0025】
表3において、MMDは皮膚表面の凹凸の状態を示し、MIUは摩擦抵抗を示す。したがって、MMDの値が低くなることは、肌のキメが細かくなることを示し、MIUの値が低くなるのは、肌のつるつるさが増すことを示す。
この表3のとおり、本発明品のすべてにおいて、対照と比較してMMD、MIU共値が低くなった。実施例7〜10において顕著に低くなっていることが分かった。
以上の結果より、本発明品は、保湿効果のみでなく、つるつる効果、そして、肌のキメを細かくする効果を有することが明らかとなった。

[Industrial application fields]
The present invention relates to a cosmetic obtained by using rice bran produced when brown rice is polished (100-92%) as a raw material.
[0002]
[Prior art]
Regarding the use of candy in cosmetics, there is a candy bag for the use of candy itself, and it has been used for cosmetic purposes since ancient times. As for the raw material made from koji, alcohol extracted (Japanese Patent Laid-Open No. 59-154971), rice paste or rice bran containing water or alcohol extracted extract (Japanese Patent Laid-Open No. 4-368314), The use of the isolated polysaccharide (Japanese Patent Publication No. 1-49688) as a cosmetic application has been proposed.
[0003]
[Problems to be solved by the invention]
In order to enhance the cosmetic effect of rice bran, it is considered that the active ingredient in rice bran is absorbed from the skin, but the main ingredients of rice bran are those with large molecular weight such as starch, protein, fat, It is difficult to absorb these directly.
An object of the present invention is to enhance the cosmetic effect by making the active ingredient of rice bran more effective and easy to absorb from the skin, which is safe for the human body, is not sticky to the skin, and is effective. .
[0004]
[Means for Solving the Problems]
The inventors of the present invention have been researching various plant components, mainly rice, which is a staple food, from the viewpoint of combining plants and animals. In the process, as a result of intensive studies on rice bran, it was found that there are a moisturizing effect, a slippery effect, and a fine skin texture by performing the following treatment, and the present invention has been completed.
(1) Enzymatic decomposition of rice bran hydrolyzate or rice bran.
(2) Extract rice bran.
(3) In extracting rice bran, enzymatic degradation or koji is allowed to act before, simultaneously with or after extraction.
(4) Enzymatic decomposition of rice bran hydrolyzate or mashing, followed by alcohol fermentation.
(5) When extracting rice bran, after subjecting it to enzymatic degradation or koji before or simultaneously with or after extraction, alcohol fermentation is further performed.
[0005]
Hereinafter, the present invention will be described in detail.
Rice bran is obtained when 92% of brown rice is refined. The brown rice can be of any variety and kind. In raw material processing, steaming, roasting (refers to sand roasting, net roasting, hot air roasting, etc.), steam roasting, surface modification such as freeze drying, photo-modification such as UV irradiation, and pressure roasting such as Patrice. Raw materials such as roasting and frying may be processed, and the effect is not changed.
[0006]
When enzymatically degrading rice bran, first add water after adding water to the rice bran. The amount of water added is appropriately selected according to the yield, workability, end use purpose, and the like. In addition, the optimal temperature of the enzyme or koji is efficient as the hydration temperature, but the enzymatic decomposition is sufficiently carried out at a low temperature for a long time. However, in the case of a low temperature of 40 ° C. or lower, it is necessary to perform some preserving. Further, the temperature may be high as long as decomposition is performed. The decomposition time may be short or long as long as decomposition is performed. That is, an extract having this effect can be obtained as long as decomposition is performed. The enzymes used here are starch degrading enzymes, proteolytic enzymes and lipolytic enzymes, and one or more of these enzymes are used. In addition, when using koji, the amount of water added, the working temperature, and the working time are the same as in the case of enzymatic degradation. The cocoon to be used may be a commonly used cocoon, and any kind and variety of gonococci are available.
[0007]
When extracting rice bran, a high extraction temperature is efficient, but it can be extracted sufficiently even at a low temperature. However, in the case of a low temperature of 40 ° C. or lower, it is desirable to make the pH not acidic or alkaline, or by adding a preservative or alcohol so that the rice bran is not spoiled. The extraction time may be long or short as long as the active ingredient can be extracted, and may be determined by the extraction temperature. The extraction may be performed under pressure, normal pressure, or reduced pressure.
[0008]
In the case of water extraction, the most serious problem is the gelatinization phenomenon. If it becomes paste-like, not only extraction efficiency will worsen but it will be extremely difficult in actual work. In order to prevent this, the reaction may be performed by adding amylase or acidifying with hydrochloric acid or the like to cut the starch. By using this method, the problem can be solved sufficiently and there is no problem in practical use.
It is also effective to perform acid decomposition extraction or alkali decomposition extraction because the active ingredient in the extract is stable to acid and alkali. In this case, neutralization and desalting are performed as necessary.
[0009]
It is also effective to perform extraction with an organic solvent. The organic solvent may be a common organic solvent such as alcohol, acetone, n-hexane, methanol or the like, but those that are harmful to the human body should be safe because the solvent must be completely removed after extraction. .
In performing the extraction, it is effective to allow enzymatic degradation or soot to act before, simultaneously with, or after the extraction.
Here, when enzymatic degradation or soot is allowed to act simultaneously with extraction, specifically, enzymatic degradation or soot is allowed to act in an organic solvent, or enzymatic degradation or soot is allowed to act under reduced pressure extraction.
In the present invention, it is more effective if alcohol fermentation is performed at the same time or after the above treatments.
[0010]
When this alcoholic fermentation is performed, the extract obtained as described above, the enzyme degradation product (including those obtained by combining enzymatic degradation and extraction), or the one that has been subjected to koji as it is or pressed, The liquid obtained by filtration is subjected to alcohol fermentation. Enzymatic degradation and alcohol fermentation may be performed simultaneously. That is, after adding water to rice bran, an enzyme or koji, and further a mash or yeast are added to perform saccharification and alcohol fermentation simultaneously. What does not use starch degrading enzyme or koji may be supplemented with sugar. When producing in large quantities, it is desirable to add rice bran in three or several stages according to sake brewing, considering the balance between saccharification and fermentation. In particular, when a small amount is processed, it is effective to add it at once. Saccharification and alcohol fermentation are carried out for about 10 to 24 days. At this time, if there is a concern about decay, an acid is added, or appropriate preservative that does not inhibit fermentation is applied.
[0011]
In addition, when alcoholic fermentation is performed, there are also advantages such as no stickiness, easy concentration, and easy concentration of active ingredients.
The product of the present invention obtained as described above is used as it is or without being separated or pressed and filtered. When it is used as it is, it is sterilized or sterilized to make a product. In addition, when the product of the present invention is blended, it is made into a dosage form such as cosmetics such as cream, face wash, milky lotion, skin lotion, cleansing, pack, soap, etc., according to an ordinary method according to the actual use. Any other commonly used ingredients may be used, and other medicinal agents may be used in combination.
[0012]
Next, tests conducted for examining the effects of the product of the present invention and the results thereof will be described.
Test example 1
A major factor that determines the suppleness and smoothness of the skin is the water content of the stratum corneum of the skin surface. Therefore, it was measured with a high-frequency conductivity measuring device.
[0013]
How is the water content and water retention capacity of the stratum corneum by conducting a stratum corneum water load test before applying 20 ml of the product of the present invention to the front arm 4 × 4 cm of 5 panelists and after 2 hours of application? We examined whether it changed.
The method of the stratum corneum water load test was based on the method of Tagami et al. That is, three arbitrary locations within a 4 × 4 cm location on the forearm delivery side where the product of the present invention is applied are determined, and the locations are marked with a ballpoint pen.
First, measure the water content of the place. After that, place a drop of distilled water in that part for 10 seconds, measure the value immediately after wiping the water drop well with gauze, then measure for 2 minutes every 30 seconds, and from the state where the absorbed moisture is lost, Check the water retention capacity of the stratum corneum.
The water retention capacity is expressed by calculating the percentage of the absorbed moisture as follows as a percentage.
[0014]
[Expression 1]
[0015]
Next, the product of the present invention was applied, and after 2 hours of application, a stratum corneum water load test was performed at a place measured before application. The measurement was performed in a room set at a temperature of 20 ° C. and a relative humidity of 40%, and the paneler entered the room 30 minutes before the measurement and measured in a resting state. The results are shown in Table 1.
[0016]
[Table 1]
[0017]
As shown in Table 1, each of the products of the present invention had a moisture content increased and a water retention ability increased after application as compared with the control water, indicating a moisturizing effect. In particular, in Examples 5 and 9 to 13, it was shown that it has a higher moisturizing effect than 0.2% sodium hyaluronate used as a moisturizing agent.
[0018]

Polyoxyethylene castor oil derivative 0.5
Ethanol 5.0
The test method consists of applying a lotion containing the product of the present invention to the right cheek of 10 panelists (female), and a blank lotion with the product of the present invention replaced with purified water on the left cheek twice a day for one month. Then, the moisture content and moisture retention ability before and after coating were examined by the same method as in Test Example 1. The results are shown in Table 2.
[0019]
[Table 2]
[0020]
As shown in Table 2, in the lotion formulated with the product of the present invention, the moisture content was clearly increased and the water retention capability was higher before and after the application for one month than that of the blank lotion. I found out.
Furthermore, a questionnaire survey was conducted on sensory evaluation. All panelists found that the skin lotion containing the product of the present invention had a moisturized skin, increased freshness, and improved makeup. I replied. There was no trouble such as rough skin.
[0021]
In this way, especially those that were enzymatically extracted and subjected to alcohol fermentation had a high moisturizing effect. However, when the ingredients were examined, the amino acid degree (titration amino acid degree) was very high, 12.4. I found out. Amino acids are known to be natural moisturizing factors. Rice bran contains about 17% fat, which is broken down into fatty acids and glycerin by lipase. These fatty acids and glycerin may also be involved in moisturizing.
[0022]
In addition, saccharides were consumed by yeast by fermentation and were 0.9% as straight sugar. Moreover, since alcohol was added and white precipitate was not produced even if the alcohol concentration was about 70%, it was found that there was no polysaccharide.
Test example 3
The smoothness effect of the skin and the effect of making the skin texture finer were examined by measurement with a dynamic friction meter.
[0023]
Fifteen subjects were applied twice a day to the right forearm report side, and the coefficient of variation (MMD) and coefficient of friction (MIU) before and after application were measured. The control was performed at the same site on the left arm. The measurement conditions are as follows.
Temperature 25 ° C
Humidity 60%
Sensor used KES-SE friction tester SE-2 type (0.5mm piano wire used)
Friction static load 50gf
Measurement speed 1mm / sec
Measuring distance 30mm (integral effective range 20mm)
The results are shown in Table 3 as average values of 15 subjects.
[0024]
[Table 3]
[0025]
In Table 3, MMD indicates the state of unevenness on the skin surface, and MIU indicates frictional resistance. Therefore, a lower MMD value indicates that the skin texture is finer, and a lower MIU value indicates that the smoothness of the skin increases.
As shown in Table 3, in all of the products of the present invention, the MMD and MIU values were lower than that of the control. It turned out that it is remarkably low in Examples 7-10.
From the above results, it was revealed that the product of the present invention has not only a moisturizing effect but also a smooth effect and an effect of making the skin texture fine.
