Description

【0001】
【発明の属する技術分野】
本発明は酒粕の発酵生成物からなる化粧料用素材配合化粧料、特に、優れた美肌効果(荒れ肌改善、くすみ改善)を発現し、使用感の優れた化粧料に関する。
【0002】
【従来の技術】
肌は年齢と共に乾燥し、弾力が失われて小じわが増え、また、メラニン色素が蓄積してシミが多くなってくる。からだ自体の新陳代謝も悪くなり、角質細胞の生まれ変わりであるターンオーバーが乱れ、それをそのままにしておくと古い角質がたまることにより、肌がざらつき、化粧のりも悪くなる。加えて古い角質にはメラニン色素が含まれているので、肌がくすんだように見えてくる。それを改善するためには保湿とターンオーバーの乱れをなおすことが必要であり、そのための成分としてアミノ酸、有機酸、ビタミン類を多く含む、酒粕発酵エキスが有効であることの研究が行われている(特許文献1)。
近年、有機酸の中でもα−ヒドロキシ酸(AHA)の肌トラブルに対する改善効果が報告されており(例えば、特許文献2および3参照)、角化症に対する有効性、ターンオーバーの正常化、シワ改善効果、細胞賦活作用等も期待できる。特に、リンゴ酸はフルーツ酸とも呼ばれているα−ヒドロキシ酸の1種で肌の生まれ変わりであるターンオーバーを正常にし、肌にたまっている古い角質を取り除き、透明感のある健康な肌に導く。
また、肌は水分の蒸散を防ぎ、ある程度の水分量を保つために天然保湿因子(NMF)と呼ばれる成分を持っており(例えば、特許文献4参照)、その成分としてはアミノ酸が主成分である。また、ビタミン類は肌にとっても肌の健康を保つためには不可欠な成分である。
一方、発酵に用いる酵母の生産するα−ヒドロキシ酸、特にリンゴ酸量を変化させた変異酵母の育種方法が提案されている(特許文献5参照)。

【発明が解決しようとする課題】
本発明の目的は、肌に対して安全かつ効果のある天然素材を用い、美肌効果(荒れ肌改善、くすみ改善)を発現し、使用感の優れた化粧料を提供することにある。
【0005】
【課題を解決するための手段】
本発明者らは鋭意研究を重ねた結果、リンゴ酸高生産酵母を利用して酒粕を再発酵させることにより、有効成分であるアミノ酸類、有機酸類、ビタミン類が増加し、中でも有機酸であるリンゴ酸が通常酵母の約10倍生産したエキスが得られ、これを配合することにより、目的とする化粧料が得られることを見出し、本発明を完成するに至った。
すなわち、本発明は、
【0006】
(1)リンゴ酸高生産変異酵母で酒粕を発酵させた後、濾過して得られる発酵生成物からなる化粧料用素材を配合したことを特徴とする化粧料、
(2)発酵生成物が、酒粕に水を添加し、5〜35℃で、3日以上発酵させた後、圧搾濾過して得られたものである上記(1)記載の化粧料、
(3)リンゴ酸高生産変異酵母がサッカロミセス・セレビシエ(Saccharomyces cerevisiae)7H6−aa11(FERM P−19000)である上記(1)記載の化粧料、
(4)リンゴ酸高生産変異酵母がサッカロミセス・セレビシエ(Saccharomyces cerevisiae)7H6−aa93(FERM P−19001)である上記(1)記載の化粧料、
(5)発酵生成物が液体である上記(1)記載の化粧料、
(6)皮膚化粧料用である上記(1)記載の化粧料、および
(7)入浴剤用である上記(1)記載の化粧料を提供するものである。
本発明の化粧料、肌に対して新陳代謝を促進させ、引いては荒れ肌を改善し、くすんだ肌に透明感を取り戻すように促す作用を示す。
【0007】
【発明の実施の形態】
本発明で用いる化粧料用素材の原料として用いる酒粕は、特に限定するものではなく、通常の清酒粕でよい。清酒粕以外に、味醂粕、米糠のような副原料を適宜添加することも可能である。
新鮮な酒粕中には、もとの清酒酵母の生育が旺盛であり、リンゴ酸高生産酵母を添加したとしてもその増殖を上回ることが多く、結果としてリンゴ酸高含有酒粕発酵生成物の調製ができない場合があるので、好ましくは、長期間冷凍した酒粕を用いる。
酒粕を発酵させる際には、水を添加する。水は、良好な発酵を行わせる点から、通常、酒粕重量1に対して、0.5〜4倍量、好ましくは、0.6〜2.5倍量用いる。
酵素剤は、必ずしも必要としないが、原料利用率の向上、目的とする成分の含有量を上げるために添加した方が好ましい。酵素剤の種類としては、糖化酵素、蛋白分解酵素、セルロース分解酵素等または麹等が挙げられ、良好な発酵を行わせる点から、酵素剤の場合、粕重量の1/100〜1/5000分、麹の場合、粕重量の1/3〜1/50分を添加する。
【0008】
用いる酵母は、通常の清酒酵母や焼酎酵母やワイン酵母などでよく、その添加量も所望の発酵状態に応じて適宜選択できるが、リンゴ酸高生産の変異酵母を使用する。
リンゴ酸デヒドロゲナーゼ遺伝子(MDH2)がコードするリンゴ酸デヒドロゲナーゼのアイソザイムは、酢酸を単一炭素源として生育させると、グリオキサル酸サイクルの一部として機能し、それゆえMDH2破壊株は表現形として酢酸資化能が欠損することが報告されている(Mol. Cell. Biol. 11, 370(1991))。そこで、本発明で使用するリンゴ酸高生産酵母は、例えば、エチルメタンスルホネート(EMS)による化学的変異法、紫外線による物理的変異法等により、親酵母株を変異させ、酢酸資化能欠損変異とリンゴ酸生産能の低下を指標にスクリーニングすることにより得られる。
以下の参考例に示すサッカロマイセス・セレビジエ清酒酵母協会7号の1倍体株から酢酸資化能欠損変異とリンゴ酸生産能を指標にスクリーニングを行なって得られたリンゴ酸高生産株であるサッカロミセス・セレビシエ(Saccharomyces cerevisiae)7H6−aa11および7H6−aa93は新規な株であり、各々、FERM P−19000およびFERM P−19001の受託番号の下、平成14年9月6日より、独立行政法人産業技術総合研究所、特許微生物寄託センターに寄託してあり、本発明においては、これらの酵母を使用することが特に好ましい。
【0009】
発酵は、5〜35℃、好ましくは、12〜25℃で、3〜20日間、好ましくは、5〜14日間行う。これにより、アミノ酸類、有機酸類、ビタミン類等の有効成分を引き出すことができる。発酵させた後、所望により圧搾前または圧搾後に食塩を添加し、液体の発酵生成物を得る。
【0010】
本発明における化粧料用素材として使用する発酵生成物は、このようにして得られた液体そのまま、または凍結乾燥処理等の自体公知の濃縮方法により、ペーストないし固形物としたものである。
本発明の化粧料用素材は自体公知の方法により化粧料に配合することができ、その配合量や他の配合成分は特に限定するものではない。
例えば、ミツロウ、カルナウバロウ、キャンデリラロウ、カカオ脂、種々の高級アルコール、種々の高級脂肪酸、ラノリン、オリーブ油、ツバキ油、ホホバ油、スクワラン、マイクロクリスタリンワックス、ワセリン、流動パラフィン、固形パラフィン、種々の高級脂肪酸エステル、種々のシリコーン誘導体などの油剤;種々の陰イオン性界面活性剤、非イオン性界面活性剤、陽イオン性界面活性剤および両イオン性界面活性剤などの界面活性剤;グリセリン、プロピレングリコール、ブチレングリコール、ソルビトール、ポリエチレングリコール、ピロリドンカルボン酸塩、水溶性の天然高分子等の溶剤・保湿剤;クインスシードゴム、トラガカントゴム、カルボキシメチルセルロース等の粘結剤;酸化防止剤;pH調整剤;金属封鎖剤;色素;香料;その他の有効成分などの公知の化粧品原料を適宜添加し、自体公知の製法にて、液体ないしは固体の化粧料、例えば、洗浄用化粧料、化粧水、クリーム、乳液、ファンデーション、口紅、アイライナー、マスカラ、アイシャドー、マニキュア、シャンプー、リンス、トリートメント、ヘアトニック、整髪料、染毛剤、ハミガキ剤、洗口剤、入浴剤などの(医薬部外品を包含する)とすることができる。
発酵生成物の効用から、特に、皮膚(整肌)化粧料や入浴剤が好ましい。

1Mリン酸緩衝液(pH8.0)4.6ml、40%グルコース溶液0.25ml、EMS 0.15mlを混合した溶液に細胞(約10個)を懸濁し、30℃で30分間処理した。EMSを中和するために5%チオ硫酸ナトリウム溶液中で10分間反応させた後、滅菌水で2回洗浄を行なった。次いで酢酸を炭素源としてナイスタチン濃縮後適宜希釈し、YPDプレートに約2万個のコロニーを形成させた。その後グルコースまたは酢酸を単一炭素源とする最小培地プレート(ディフコ社製イーストニトロゲンベース0.67%、グルコース2%または酢酸ナトリウム2%、寒天2%、pH5.5)にレプリカし、30℃、6日間培養後、酢酸資化能欠損株176株を分離した。分離された176株についてYPD15培地(グルコース15%、ペプトン2%、酵母エキス1%)で25℃、6日間静置培養を行ない、培養上澄の有機酸分析を行ないリンゴ酸のみが増加した変異株7H6−aa11と7H6−aa93の2株を分離した。
(清酒小仕込み試験)
上記2株のリンゴ酸生産能を確認すべく、清酒小仕込み試験を行なった(総米200g、2段仕込み、15℃一定、汲み水140%)。留後16日目にもろみをろ過し、上澄の成分分析を行なった。以下表1および2に結果を示す。
【0012】
【表1】

【表2】
Figure 2004137236
上記結果より、7H6−aa11と7H6−aa93は親株と比較して、約4〜5倍のリンゴ酸を生成していた。また表1よりアルコール生産能等から判断して、清酒酵母としても問題ない酵母であるといえる。
【0013】

参考例2
リンゴ酸高生産酵母による酒粕発酵生成物の調製
冷凍酒粕5kgに対して、水5Lと酵素剤(アマノエンザイム社製グルク100)2gを添加し、リンゴ酸高生産酵母(7H−6aa11および7H−6aa93)または通常の清酒酵母(親株)2×10個/mlとなるように植菌し、15℃、14日間発酵させた。発酵終了後、遠心分離(8000rpm、10分間)を行い液体の酒粕発酵エキス約2.5Lを取得した。
表7に酒粕発酵エキス各種成分分析を行なった結果を示す。
また、対照として酒粕を再発酵させていないものの成分を分析した結果を示す(表中水抽出)。
【表7】
Figure 2004137236
表7中の水抽出液とそれ以外の酒粕発酵生成物の結果を比較すると、発酵したものは化粧料用素材として有用な有機酸含量、アミノ酸含量ともに高かった。このことは発酵によって酵母が生成したものといえ、酒粕抽出液中にもともと豊富に含まれる有機酸やアミノ酸の含量をさらに再発酵することによって高めることができる。
また、リンゴ酸高生産酵母を用いた酒粕発酵エキスについては、親株のものと比較してリンゴ酸の含量が特異的に約8〜10倍高くなっており、リンゴ酸高生産酵母を用いて発酵させることによって美白効果のあるAHAを増加させることができた。その他の有機酸、アミノ酸については特に差は見られない。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cosmetic material blended cosmetic material comprising a fermentation product of sake lees, and more particularly to a cosmetic material which exhibits excellent skin effect (improves rough skin and dullness) and has excellent feeling in use.
[0002]
[Prior art]
The skin dries with age, loses elasticity, increases fine wrinkles, and accumulates melanin pigment and increases stains. The metabolism of the body itself also deteriorates, and the turnover, which is the reincarnation of keratinocytes, is disrupted. If left untouched, old keratin accumulates, making the skin rougher and worsening makeup. In addition, the old keratin contains melanin, which makes the skin look dull. In order to improve it, it is necessary to correct the disorder of moisturizing and turnover, and studies on the effectiveness of fermented sake lees extract containing many amino acids, organic acids and vitamins as components for that purpose have been conducted. (Patent Document 1).
In recent years, among the organic acids, α-hydroxy acid (AHA) has been reported to have an effect of improving skin troubles (for example, see Patent Documents 2 and 3), and is effective against keratosis, normalizing turnover, and improving wrinkles. An effect, a cell activating effect, etc. can also be expected. In particular, malic acid is a kind of α-hydroxy acid, also called fruit acid, which normalizes turnover, which is the reincarnation of the skin, removes old keratin that has accumulated on the skin, and leads to a transparent and healthy skin. .
In addition, the skin has a component called natural moisturizing factor (NMF) to prevent evaporation of water and maintain a certain amount of water (for example, see Patent Document 4), and amino acids are the main components. . Vitamins are also essential ingredients for skin to maintain skin health.
On the other hand, a method for breeding a mutant yeast in which the amount of α-hydroxy acid, particularly malic acid, produced by yeast used for fermentation has been changed has been proposed (see Patent Document 5).

[Problems to be solved by the invention]
An object of the present invention is to provide a cosmetic composition that uses a natural material that is safe and effective for the skin, exhibits a beautiful skin effect (improves rough skin and dullness), and has an excellent feeling in use.
[0005]
[Means for Solving the Problems]
The present inventors have conducted intensive studies, and as a result of re-fermenting sake lees using malic acid high producing yeast, amino acids, organic acids, and vitamins as active ingredients are increased, and among them, organic acids are An extract in which malic acid is usually produced about 10 times that of yeast was obtained, and it was found that the desired cosmetic could be obtained by blending the extract, and the present invention was completed.
That is, the present invention
[0006]
(1) Cosmetics characterized by blending a material for cosmetics comprising a fermentation product obtained by fermenting sake lees with malic acid high-producing mutant yeast and then filtering.
(2) The cosmetic according to (1) above, wherein the fermentation product is obtained by adding water to sake lees, fermenting at 5 to 35 ° C. for 3 days or more, and then pressing and filtering.
(3) The cosmetic according to the above (1), wherein the malic acid high-producing mutant yeast is Saccharomyces cerevisiae 7H6-aa11 (FERM P-19000),
(4) The cosmetic according to the above (1), wherein the malic acid-high producing mutant yeast is Saccharomyces cerevisiae 7H6-aa93 (FERM P-19001).
(5) The cosmetic according to (1), wherein the fermentation product is a liquid.
(6) The cosmetic according to (1), which is used for skin cosmetics, and (7) the cosmetic according to (1), which is used for bath salts.
The cosmetic of the present invention has an effect of promoting metabolism on the skin, improving the rough skin by pulling the skin, and promoting the clarity of the dull skin.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
The sake lees used as a raw material of the cosmetic material used in the present invention is not particularly limited, and may be ordinary sake lees. In addition to sake lees, auxiliary materials such as mirin lees and rice bran can be appropriately added.
The growth of the original sake yeast in fresh sake lees is vigorous, and even when the malic acid-high producing yeast is added, it often exceeds the growth, resulting in the preparation of malic acid-rich sake lees fermentation products. In some cases, sake lees frozen for a long period of time are preferably used.
When fermenting sake lees, water is added. Water is usually used in an amount of 0.5 to 4 times, preferably 0.6 to 2.5 times the weight of sake lees in terms of good fermentation.
Although the enzyme agent is not necessarily required, it is preferable to add the enzyme agent in order to improve the raw material utilization rate and increase the content of the target component. Examples of the type of the enzymatic agent include saccharifying enzymes, proteolytic enzymes, cellulolytic enzymes and the like, and koji and the like. In the case of koji, 1/3 to 1/50 minute of the weight of the lees is added.
[0008]
The yeast to be used may be ordinary sake yeast, shochu yeast, wine yeast, or the like, and the amount of the yeast to be added can be appropriately selected according to the desired fermentation state.
The malate dehydrogenase isozyme, encoded by the malate dehydrogenase gene (MDH2), functions as part of the glyoxalate cycle when grown on acetic acid as a sole carbon source, and thus the MDH2-disrupted strain is phenotypically assimilated to acetate. It has been reported that the function is lost (Mol. Cell. Biol. 11, 370 (1991)). Therefore, the malic acid-producing yeast used in the present invention is obtained by mutating the parent yeast strain by a chemical mutation method using ethyl methanesulfonate (EMS), a physical mutation method using ultraviolet light, etc. And a decrease in malic acid-producing ability as an index.
Saccharomyces cerevisiae, a malic acid-producing strain obtained by screening from a haploid strain of Saccharomyces cerevisiae Sake Yeast Association No. 7 shown in the following Reference Examples using mutations deficient in acetic acid assimilation ability and malic acid producing ability as indices. Saccharomyces cerevisiae 7H6-aa11 and 7H6-aa93 are new strains, each of which has a deposit number of FERM P-19000 and FERM P-19001. These yeasts are deposited at the Research Institute and the Patent Microorganisms Depositary Center, and in the present invention, it is particularly preferable to use these yeasts.
[0009]
The fermentation is carried out at 5 to 35 ° C, preferably 12 to 25 ° C, for 3 to 20 days, preferably 5 to 14 days. Thereby, active ingredients such as amino acids, organic acids, and vitamins can be extracted. After fermentation, if desired, before or after pressing, salt is added to obtain a liquid fermentation product.
[0010]
The fermentation product used as a material for cosmetics in the present invention is a liquid obtained as such or a paste or solid obtained by a concentration method known per se such as freeze-drying treatment.
The cosmetic material of the present invention can be blended with the cosmetic by a method known per se, and the blending amount and other blending components are not particularly limited.
For example, beeswax, carnauba wax, candelilla wax, cocoa butter, various higher alcohols, various higher fatty acids, lanolin, olive oil, camellia oil, jojoba oil, squalane, microcrystalline wax, vaseline, liquid paraffin, solid paraffin, various high grades Oils such as fatty acid esters and various silicone derivatives; various surfactants such as anionic surfactants, nonionic surfactants, cationic surfactants and amphoteric surfactants; glycerin, propylene glycol , Butylene glycol, sorbitol, polyethylene glycol, pyrrolidone carboxylate, solvent and humectant such as water-soluble natural polymer; binder such as quince seed rubber, tragacanth rubber, carboxymethyl cellulose; antioxidant; pH adjuster; Blocking agent; Liquid or solid cosmetics, for example, washing cosmetics, lotions, creams, emulsions, foundations, lipsticks, by appropriately adding known cosmetic ingredients such as ingredients; fragrances; other active ingredients, and the like, in a manner known per se. (Including quasi-drugs) such as, eyeliner, mascara, eye shadow, nail polish, shampoo, rinse, treatment, hair tonic, hair styling, hair dye, toothpaste, mouthwash, bath preparation, etc. Can be.

【Example】
Next, the present invention will be described in more detail with reference to Reference Examples and Examples, but the present invention is not limited thereto.
Reference Example 1
Acquisition of malic acid high producing strain (method)
1M phosphate buffer (pH 8.0) 4.6 ml, 40% glucose solution 0.25 ml, was suspended cells (about 109 cells) in a solution obtained by mixing EMS 0.15 ml, was treated at 30 ° C. 30 min. After a reaction in a 5% sodium thiosulfate solution for 10 minutes to neutralize EMS, washing was performed twice with sterilized water. Subsequently, nystatin was concentrated using acetic acid as a carbon source and then appropriately diluted to form about 20,000 colonies on a YPD plate. Then, the medium was replicated on a minimal medium plate (0.67% yeast nitrogen base, 2% glucose or 2% sodium acetate, 2% agar, pH 5.5, manufactured by Difco) using glucose or acetic acid as a single carbon source, and 30 ° C. After culturing for 6 days, 176 strains lacking the ability to utilize acetic acid were isolated. The isolated 176 strain was subjected to static culture at 25 ° C. for 6 days in a YPD15 medium (glucose 15%, peptone 2%, yeast extract 1%) at 25 ° C., and the organic acid analysis of the culture supernatant was performed. Two strains, strains 7H6-aa11 and 7H6-aa93, were isolated.
(Sake small preparation test)
In order to confirm the malic acid-producing ability of the above two strains, a small sake charging test was carried out (total rice 200 g, two-stage charging, constant at 15 ° C., 140% pumping water). On the 16th day after the distillation, the mash was filtered and the supernatant was subjected to component analysis. The results are shown in Tables 1 and 2 below.
[0012]
[Table 1]
Figure 2004137236
[Table 2]
Figure 2004137236
From the above results, 7H6-aa11 and 7H6-aa93 produced about 4 to 5 times as much malic acid as the parent strain. In addition, judging from alcohol production ability and the like from Table 1, it can be said that the yeast is a problem-free yeast as a sake yeast.
[0013]
(Bacteriological properties of 7H6-aa11)
1) Morphological properties After culturing in YPD medium at 30 ° C. for 2 days, the cells were observed with a microscope.
a) Shape: oval b) Size: 4.5-7.0 μm in length, 3.5-5.0 μm in width
c) Form of growth: budding 2) Physiological properties a) Utilization of carbon source and nitrogen source Utilization of carbon source was determined using yeast nitrogen medium (manufactured by Difco) and assimilation of nitrogen source. Used yeast carbon medium (manufactured by Difco) to observe its proliferation.
Tables 3 and 4 show the results.
[Table 3]
Figure 2004137236
[Table 4]
Figure 2004137236
The above morphological and physiological results indicate that 7H6-aa11 is a yeast belonging to Saccharomyces cerevisiae. However, the strain was determined to be a new strain in that it lacked acetic acid availability and produced higher amounts of malic acid than the parent strain.
[0014]
(Bacteriological properties of 7H6-aa93)
1) Morphological properties After culturing in YPD medium at 30 ° C. for 2 days, the cells were observed with a microscope.
a) Shape: oval b) Size: 4.5-7.0 μm in length, 3.5-5.0 μm in width
c) Form of growth: budding 2) Physiological properties a) Utilization of carbon source and nitrogen source The utilization of carbon source was determined using yeast nitrogen medium (manufactured by Difco) and assimilation of nitrogen source. The growth was observed using yeast carbon medium (manufactured by Difco).
Tables 5 and 6 show the results.

Reference Example 2
Preparation of Sake Cake Fermentation Product by Malic Acid High Yeast To 5 kg of frozen sake cake, 5 L of water and 2 g of an enzyme agent (Gluc 100 manufactured by Amano Enzyme Co., Ltd.) were added, and malic acid high producing yeasts (7H-6aa11 and 7H-6aa93) were added. ) Or ordinary sake yeast (parent strain) at 2 × 10 7 cells / ml and fermented at 15 ° C. for 14 days. After the fermentation, centrifugation (8000 rpm, 10 minutes) was performed to obtain about 2.5 L of a liquid sake lees fermented extract.
Table 7 shows the results of analysis of various components of the sake lees fermented extract.
In addition, the results of analyzing the components of sake lees without refermentation as a control are shown (water extraction in the table).
[Table 7]
Figure 2004137236
Comparing the results of the water extract in Table 7 with the other fermentation products of sake lees, the fermented product had high organic acid content and amino acid content useful as a material for cosmetics. This can be said to be yeast produced by fermentation, and can be enhanced by further refermenting the content of organic acids and amino acids originally rich in the sake lees extract.
In addition, as for the sake lees fermented extract using the malic acid high producing yeast, the malic acid content is specifically about 8 to 10 times higher than that of the parent strain, and the fermentation using the malic acid high producing yeast is performed. By doing so, AHA having a whitening effect could be increased. There is no particular difference in other organic acids and amino acids.
