Abstract

【0001】
【発明の属する技術分野】
本発明は、コラーゲン合成亢進作用を有する哺乳動物の乳清またはその分画成分と糖蜜から抽出されるメラニン生成抑制成分を含むエキスを生理活性物質として同時に含有することを特徴とする皮膚化粧料(化粧品、医薬部外品たる薬用化粧料を含む。以下おなじ。)であって、コラーゲン合成亢進剤のコラーゲン合成亢進能を相乗的に増強する効果を発揮させうる皮膚化粧料に関するものである。
【0002】
【従来の技術】
本発明の背景としては、皮膚の主要基質蛋白であるコラーゲンが皮膚の引っ張り強さに関与していることはよく知られている。皮膚中のコラーゲンは過齢とか紫外線照射によりかなり減少することが判っている。これらが破壊又は分解されると皮膚の引っ張り強度が減少し、皺やたるみが生ずる。皮膚の組織学と太陽光線が照射された皮膚のコラーゲンレベルの減少とにいくつかの相関性があることが報告されている(Chen.S.,et al.,THE New Eng.Jou.of Medicine(1993),321)。また皮膚コラーゲン量は20才から80才までの間に65%減少し、真皮の厚さは薄くなる(Shuster,S.,British Journal of Der− matology,93,639,1975)。これらの研究結果により、真皮繊維芽細胞のコラーゲン合成を特異的に促進することができれば、真皮のコラーゲン含有量が増加し、真皮の厚さを増し、それに伴って代謝回転も活性化され、引っ張り強度、伸展性、柔軟性を改善し、その結果皺に代表される老化皮膚の形態的変化を抑制することが可能である。
【0003】
この観点から、種々のコラーゲン合成亢進剤の皮膚外用剤としての使用が提案されている。例えばレチン酸がI型コラーゲンを回復させ、コラーゲン合成と皺の消失との間の対応作用が示され、米国等では実用化している。しかしこのものは治療域と安全域の範囲が極めて狭く皮膚傷害等の恐れも高い。またL−アスコルビン酸及びその誘導体も表皮メラノサイトのメラニン生成抑制効果と同時に、コラーゲン合成促進効果を有しており、皮膚外用材として多用されている。しかしL−アスコルビン酸類は、L−アスコルビン酸に代表されるように酸化、熱、光に対して不安定であるという欠点を有する。また一般的に生体皮膚からの吸収が悪く、真皮まで吸収させることが難しく、実際の使用に当たって、コラーゲン合成亢進剤としての効果はそれ程期待し得ない。その他コラーゲン合成亢進剤として、ベツリン酸(特許公開平8−208424)、ミッドカイン(特許公開平9−157183)、さらには硫酸アルギン酸、ローズマリーのエッセンス、シラカバのエッセンス等種々物質が多数報告がされているがこれらもまた充分満足すべきものではない。

【特許文献2】
特許第2080442公報(特公平7ー103012号公報)
【0005】
【発明が解決しようとする課題】
本発明は、このような現状のもと加齢変化、紫外線照射等に伴う皺の増加を、皮膚の繊維芽細胞のコラーゲン合成を促進させることにより、抑制し、張り、艶のある肌に改善させるのにより有効な皮膚化粧料を提供することにある。
【0006】
特許文献1のみでは、コラーゲン合成亢進効果が十分に得られないし、特許文献2のみでは、コラーゲン合成亢進効果は得られない。このため、本発明者等は哺乳動物の乳清及びその分画成分、殊に分娩後5日以内の初乳の乳清及びその分画成分にコラーゲン合成亢進効果を有することに着目し、皮膚化粧料への応用を実用化した。
【0007】
一方糖蜜から抽出される着色成分を除去して得られるエキスは、高い美白効果を有していることが開示されている。しかしこのものにコラーゲン合成亢進剤のコラーゲン合成亢進能の増強効果を相乗的に高めるという事実については全く知られていない。
【0008】
【課題を解決するための手段】
そこで、発明者らは、哺乳動物の乳清由来のコラーゲン合成亢進剤の新なる応用展開を図るために鋭意研究努力を重ねた結果、哺乳動物の乳清由来のコラーゲン合成亢進剤と糖蜜から抽出されるエキスとを含有する皮膚化粧料としたり、或いは、乳清がヒト、ウシ、ヤギ、ヒツジ、ブタの乳清より選ばれた1種又は2種以上である皮膚化粧料等としたことにより、コラーゲン合成亢進剤のコラーゲン合成亢進能を相乗的に増強する効果を発揮し、前記課題を解決したものである。
【0009】
【発明の実施の形態】
(1)本発明の皮膚化粧料の必須成分である乳清は、ヒト、ウシ、ヤギ、ヒツジ、ブタ等の哺乳動物から採取された乳汁、或いはその乳汁を予め乾燥粉末化した後水に溶解したものが用いられ、通常、遠心分離によって最上層の脂肪分を取りのぞいて脱脂後、種々の方法でカゼイン画分を除去して得られる。カゼイン画分の除去は通常、大きく二つの方法に分けられる。一つは乳酸、塩酸、硫酸等の酸を添加によりpH4.4〜4.6程度の酸性でカゼインを等電点沈殿させ、もう一つはキモシン等の酵素の作用によりカゼインを凝固させ、いずれも不溶化したカゼイン画分を濾過、遠心分離或いはデカンテーション等により除去する方法で行なわれ、得られるカゼイン画分は、前者を酸カゼイン、後者をレンネットカゼインと呼ぶ。
【0010】
なお、哺乳動物の分娩後5日以内に採取される初乳から得られる初乳清中のコラーゲン合成亢進作用が、特に高いことが明らかとなり、従来、初乳中にはグロブリン含量が多いことが知られていることからも、生理学上、重要な意味をもつものと考えられる。
【0011】
更に、乳清中のコラーゲン合成亢進作用成分の分画法につき検討した結果、乳清の酸・アルコール処理により、その可溶画分に極めて効率的に移行することが判明した。この際酸・アルコールの処理条件はpH1〜5、アルコール濃度10〜50%(V/V%)好ましくはpH2.0〜4.5,アルコール濃度30〜40%(V/V%)に調整する。使用するアルコールはメタノール、エタノール、イソプロパノール、n−ブタノール等任意のものが用いられるが、好ましくはエタノールが用いられる。使用する酸も特に限定しない。酸・アルコール処理の結果生ずる不溶物は濾過、遠心分離或いはデカンテーション等によりコラーゲン合成亢進作用成分を豊富に含有する可溶画分が得られる。酸・アルコール可溶画分は必要に応じてpHを調整し、減圧濃縮、限外濾過或いは凍結濃縮の方法により濃縮してもよく、また、凍結乾燥、噴霧乾燥或いは平板乾燥等の方法により乾燥粉末化することも可能である。
【0012】
乳清中のコラーゲン合成亢進作用成分の分画法については、酸・アルコールによる処理に限らず、乳清中に存在するコラーゲン合成亢進作用成分が効率良く分画できるものであれば如何なる方法でも良く、例えば、脱乳糖、脱塩、溶剤分画、塩析、限外濾過、ゲル濾過、イオン交換法等によっても分画、精製或いは濃縮することができる。
【0013】
(2)本発明の皮膚化粧料の必須成分である糖蜜から抽出されるメラニン生成抑制成分を含むエキスは、コラーゲン合成亢進剤のコラーゲン合成亢進能を相乗的に増強する効果のある成分が抽出できる方法であれば、特に限定されるものではない。着色成分を除去し、効率よくメラニン生成抑制成分を抽出できる方法であれば、その目的を容易に達成することができる。具体的には、水、メタノール、エタノール、n−ブタノール、イソプロピルアルコール、1,3−ブチレングリコール、プロピレングリコール、グリセリン、酢酸エチル、ヘキサン、アセトン、ベンゼン、トルエン、クロロホルム、ジエチルエーテル、メチルセロソルブ等またはこれらの混液を抽出溶媒として使用することができる。より好ましくはアルコールまたはアルコールと水の混液がのぞましい。抽出する溶媒の種類により多くの場合、糖蜜中に存在する着色成分が同時に抽出される場合が多い。着色成分が混入すると、皮膚化粧料に配合した場合、化粧料そのものを著しく着色し一般的な化粧料としては使用し難い。着色成分を除去する手段としては、活性炭、活性白土、またはシリカゲル、活性アルミナ、合成樹脂吸着剤、逆浸透膜等を用いる方法を選択することができる。また必要に応じて、スプレードライ、凍結乾燥等により乾燥して使用することも可能である。
【0014】
(3)本発明の皮膚化粧料は、必須成分として哺乳動物の乳清由来のコラーゲン合成亢進剤と糖蜜から抽出されるメラニン生成抑制成分を含むエキスとを含有することを特徴とする。本発明の化粧料に使用する哺乳動物の乳清由来のコラーゲン合成亢進剤と糖蜜から抽出されるメラニン生成抑制成分を含むエキスの配合量は、症状の程度、剤形などによって適宜変更できるが通常それぞれ乾燥固形分として0.1〜3.0重量%の範囲で用いられる。
【0015】
本発明の化粧料には上記の必須成分の他、化粧料の配合成分として一般的に用いられる界面活性剤、多価アルコール、低級アルコール、増粘剤、紫外線吸収剤、散乱剤、防腐剤、酸化防止剤、キレート剤、pH調整剤、香料、色素、水等を適宜配合することができる。
【0016】
これらの配合成分の具体例を以下に示す。

【実施例】
以下にこの発明に係る化粧料について実施例、試験例及び処方例を示すことにより、この発明を明確にするが、本発明がこれらの実施例等のみに限定されないことは言うまでもない。
試験等を実施するに当たり次の試料を調整した。
【0022】
試料A コラーゲン合成亢進作用を有する牛初乳清の分画成分の調製
牛の分娩後1〜5日経過時に採取された初乳10lを遠心分離(15000g×30min)し最上層の脂肪分を除去した後、30℃に加温、適量のキモシンを加え2時間攪拌後、遠心分離(720g×30min)し、その上清をメンブランフィルターにて濾過し清澄な初乳清を得た。この初乳清5lにメタノール3lを混和し、酢酸でpH3.0とし、更にホモミキサーで2時間混合した。その後デカンテーションにより上清を分取し、分画分子量1万の限外濾過膜で2倍濃縮し、セライト濾過により清澄な初乳清分画成分を得た。
【0023】
試料B 糖蜜から抽出されるメラニン生成抑制成分を含むエキスの調製
糖蜜1kgに70%メタノール水溶液5lを加え、攪拌抽出した後、濾過により不溶物を取り除く。濾液を減圧濃縮しメタノールを取り除く。これに水41、活性炭120gを加えて1時間攪拌する。次にこれを濾過しエキス41を得る。
【0024】
試料C 試料Bの調整過程で得られた不溶物に水4l、活性炭120gを加えて1時間攪拌する。次にこれを濾過しエキス4lを得る。
【0025】
試料Bメラニン生成抑制効果試験
B16メラノーマ細胞2×105 個を径6cmの培養シャーレ中、試料B5mlを添加した牛胎児血清加イーグルMEM培地を用い、5%炭酸ガスを含有する空気下37℃、7日間培養した。その後細胞は0.025%トリプシンを含むダルベッコリン酸緩衝液で剥離し、細胞数の測定を行い、遠心分離し得られた細胞の白色化の程度を肉眼的に観察した。コントロールとして試料Bの代わりに滅菌精製水を用いた。表1に示す様に、試料添加区とコントロールとの間に、細胞数には殆ど変化はなかったが、白色化度においては、試料添加区では顕著に白色化したのに対し、コントロールでは殆ど変化は無かった。このことから試料Bは糖蜜から抽出されるメラニン生成抑制成分を含むエキスであることが確認できる。
一方、糖蜜の70%メタノール不溶物はメラニン生成抑制成分を含まないことが解る。
【0026】
【表1】
【0027】
試験例1 培養繊維芽細胞のコラーゲン合成能試験
継代培養してきたWI−38細胞(人胎児肺正常2倍体細胞PDL40)を、試験前日に新しいMEM培地(10%牛胎児血清含有)に培地交換し24時間培養後(preculture)後、培養上清に試料を添加、〔3H〕−プロリンを終濃度2μCiとなるよう添加し、6時間、5%CO2+95%Air,37℃で培養した。なお、試料無添加区を対象とした。その後培養上清を取り除き、細胞画分にコラーゲナーゼタイプ(Worthington社製)5unitu/mlを37℃18時間作用させ、トリクロロ酢酸溶液で除蛋白を行い、この可溶画分の〔3H〕−プロリン量をシンチレーターにてカウントしコラーゲン量とした。なお、非コラーゲン蛋白質量は、コラゲナーゼ無処理の総〔3H〕−プロリン量からコラーゲン量を差し引いた値として表した。培地へ添加した試料の種類と試料の添加量及びその試験結果は表2の通りである。
【0028】
【表2】
【0029】
表2より明らかな様に牛初乳清由来のコラーゲン合成亢進剤と糖蜜から抽出されるメラニン生成抑制成分を含むエキスを同時に配合すると、コラーゲン合成亢進剤のコラーゲン合成促進能を有意に増強する効果が有ることが解る。試験区7及び8から解るように、糖蜜から抽出されるメラニン生成抑制成分を含まないエキス(この場合はメタノール不溶物)は、これ自体にコラーゲン合成促進効果はなく、コラーゲン合成亢進剤のコラーゲン合成亢進能を増強する効果も無いことが解る。
【0030】

【発明の効果】
以上詳述した如く、この発明に係る哺乳動物の乳清由来のコラーゲン合成亢進剤と糖蜜から抽出されるメラニン生成抑制成分を含むエキスとを含有することを特徴とする皮膚化粧料は、乳清由来のコラーゲン合成亢進剤を単独でしようとするのに比して、糖蜜から抽出されるメラニン生成抑制成分を含むエキスを同時に配合すると、コラーゲン合成亢進剤のコラーゲン合成亢進能を相乗的に増強する効果を奏するものである。特に、糖蜜から抽出されるメラニン生成抑制成分を含むエキスのみには、コラーゲン合成亢進作用はないが、哺乳動物の乳清由来のコラーゲン合成亢進剤に包有させることで、該コラーゲン合成亢進剤が持っているコラーゲン合成亢進する能力を相乗的に増加させることができるという特有の効果を発揮し得るものである。また同時に配合する本発明に係わる糖蜜エキスは、当然のことながらメラニン生成抑制成分を含むエキスであるから、コラーゲン合成亢進能増強効果を示すと同時に皮膚化粧料としては好ましい作用である美白効果を同時に現すことができる利点がある。[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a skin cosmetic comprising, as a physiologically active substance, a whey of a mammal having a collagen synthesis-enhancing effect or an extract containing a melanin production-inhibiting component extracted from molasses and a fractional component thereof at the same time. Cosmetics and quasi-drugs, including cosmeceuticals. The same shall apply hereinafter), which relates to a skin cosmetic capable of synergistically enhancing the ability of a collagen synthesis enhancer to enhance collagen synthesis.
[0002]
[Prior art]
As the background of the present invention, it is well known that collagen, which is a major protein of the skin, is involved in the tensile strength of the skin. Collagen in the skin has been found to be significantly reduced by aging and UV irradiation. When these are broken or decomposed, the tensile strength of the skin decreases, and wrinkles and sagging occur. Several correlations have been reported between skin histology and reduction in collagen levels in sun-irradiated skin (Chen. S., et al., THE New Eng. Jou. Of Medicine). (1993), 321). In addition, the amount of skin collagen is reduced by 65% between the ages of 20 and 80, and the thickness of the dermis is reduced (Shuster, S., British Journal of Der-matology, 93, 639, 1975). Based on these findings, the ability to specifically promote collagen synthesis in dermal fibroblasts would increase the dermal collagen content, increase the thickness of the dermis, and, consequently, activate turnover and pull. It is possible to improve strength, extensibility, and flexibility, thereby suppressing morphological changes of aged skin represented by wrinkles.
[0003]
From this viewpoint, use of various collagen synthesis enhancers as external preparations for skin has been proposed. For example, retinoic acid restores type I collagen and shows a corresponding effect between collagen synthesis and disappearance of wrinkles, and has been put to practical use in the United States and the like. However, this has a very narrow range of the treatment area and the safety area, and has a high possibility of skin injury. L-ascorbic acid and its derivatives also have a melanin production inhibitory effect on epidermal melanocytes and a collagen synthesis promoting effect, and are widely used as external skin materials. However, L-ascorbic acids, as represented by L-ascorbic acid, have the disadvantage of being unstable to oxidation, heat and light. Further, in general, absorption from living skin is poor, and it is difficult to absorb it into the dermis. In actual use, the effect as a collagen synthesis enhancer cannot be expected so much. In addition, various substances such as betulinic acid (Patent Publication No. 8-208424), midkine (Patent Publication No. 9-157183), alginic acid sulfate, rosemary essence, and birch essence have been reported as collagen synthesis enhancers. However, these are also not satisfactory enough.

[Problems to be solved by the invention]
The present invention suppresses the increase in wrinkles due to age-related changes, ultraviolet irradiation, and the like under the current conditions by promoting collagen synthesis of fibroblasts of the skin, thereby improving skin with firmness and gloss. To provide a more effective skin cosmetic.
[0006]
Patent Document 1 alone does not provide a sufficient collagen synthesis enhancing effect, and Patent Document 2 alone does not provide a collagen synthesis enhancing effect. Therefore, the present inventors have focused on the fact that mammalian whey and its fraction components, particularly colostrum whey within 5 days after parturition, and its fraction components have an effect of enhancing collagen synthesis, Practical application of cosmetics.
[0007]
On the other hand, it is disclosed that an extract obtained by removing a coloring component extracted from molasses has a high whitening effect. However, nothing is known about the fact that a collagen synthesis enhancer synergistically enhances the effect of enhancing collagen synthesis of a collagen synthesis enhancer.
[0008]
[Means for Solving the Problems]
Therefore, the present inventors have made intensive research efforts to develop new applications of mammalian whey-derived collagen synthesis enhancer, and as a result, extracted from mammalian whey-derived collagen synthesis enhancer and molasses. Or a skin cosmetic containing whey, which is one or more selected from human, cow, goat, sheep and pig whey. The present invention has solved the above-mentioned problem by exhibiting an effect of synergistically enhancing the ability of a collagen synthesis enhancer to enhance collagen synthesis.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
(1) Whey, which is an essential component of the skin cosmetic of the present invention, is milk collected from mammals such as humans, cows, goats, sheep, pigs, or the like, or is dried and powdered beforehand and then dissolved in water. Usually, it is obtained by removing fat in the uppermost layer by centrifugation to remove fat and then removing the casein fraction by various methods. The removal of the casein fraction is generally divided into two main methods. One is to add casein such as lactic acid, hydrochloric acid, sulfuric acid and the like to make it isoelectrically precipitate casein under acidic condition of pH 4.4-4.6, and the other is to coagulate casein by the action of enzymes such as chymosin. The insoluble casein fraction is also removed by filtration, centrifugation, decantation, or the like, and the resulting casein fraction is referred to as acid casein and the latter as rennet casein.
[0010]
Collagen whey obtained from colostrum collected within 5 days after parturition of a mammal has a particularly high collagen synthesis-enhancing effect. Conventionally, colostrum has a high globulin content. From what is known, it is considered to have important physiological significance.
[0011]
Furthermore, as a result of examining the fractionation method of the collagen synthesis-enhancing component in whey, it was found that treatment with whey acid / alcohol extremely efficiently transferred to the soluble fraction. At this time, the treatment conditions of the acid / alcohol are adjusted to pH 1 to 5 and alcohol concentration to 10 to 50% (V / V%), preferably to pH 2.0 to 4.5, and alcohol concentration to 30 to 40% (V / V%). . As the alcohol to be used, any one such as methanol, ethanol, isopropanol and n-butanol is used, but ethanol is preferably used. The acid used is not particularly limited. The insolubles resulting from the acid / alcohol treatment can be filtered, centrifuged, decanted, or the like to obtain a soluble fraction rich in collagen synthesis-enhancing components. The acid / alcohol soluble fraction may be adjusted for pH as necessary and concentrated by vacuum concentration, ultrafiltration or freeze concentration, or dried by freeze drying, spray drying or plate drying. Powdering is also possible.
[0012]
The method for fractionating the collagen synthesis-enhancing component in whey is not limited to treatment with an acid or alcohol, and any method may be used as long as the collagen synthesis-enhancing component present in whey can be efficiently fractionated. For example, fractionation, purification or concentration can also be carried out by de-lactose, desalting, solvent fractionation, salting out, ultrafiltration, gel filtration, ion exchange, or the like.
[0013]
(2) The extract containing a melanin production-inhibiting component extracted from molasses, which is an essential component of the skin cosmetic of the present invention, can extract a component having an effect of synergistically enhancing the collagen synthesis-enhancing ability of the collagen synthesis-enhancing agent. The method is not particularly limited as long as it is a method. If the method can remove the coloring component and efficiently extract the melanin production suppressing component, the object can be easily achieved. Specifically, water, methanol, ethanol, n-butanol, isopropyl alcohol, 1,3-butylene glycol, propylene glycol, glycerin, ethyl acetate, hexane, acetone, benzene, toluene, chloroform, diethyl ether, methyl cellosolve and the like or These mixtures can be used as an extraction solvent. More preferably, alcohol or a mixture of alcohol and water is preferred. In many cases, the coloring components present in molasses are often simultaneously extracted depending on the type of the solvent to be extracted. When a coloring component is mixed, the cosmetic itself is markedly colored when blended into a skin cosmetic, and is difficult to use as a general cosmetic. As a means for removing the coloring component, a method using activated carbon, activated clay, silica gel, activated alumina, a synthetic resin adsorbent, a reverse osmosis membrane, or the like can be selected. Further, if necessary, it is also possible to use by drying by spray drying, freeze drying or the like.
[0014]
(3) The skin cosmetic of the present invention is characterized by containing a collagen synthesis enhancer derived from mammalian whey and an extract containing a melanin production-inhibiting component extracted from molasses as essential components. The amount of the collagen whey-derived collagen synthesis enhancer derived from mammalian whey and the extract containing a melanin production-inhibiting component extracted from molasses used in the cosmetic composition of the present invention can be appropriately changed depending on the degree of symptoms, dosage form, etc. Each is used in a range of 0.1 to 3.0% by weight as a dry solid content.

【Example】
Hereinafter, the present invention will be clarified by showing Examples, Test Examples, and Formulation Examples of the cosmetic according to the present invention, but it goes without saying that the present invention is not limited only to these Examples.
The following samples were prepared for conducting tests and the like.
[0022]
Sample A Preparation of fractional components of bovine colostrum having collagen-synthesizing activity 10 l of colostrum collected 1-5 days after calving of cows was centrifuged (15000 g × 30 min) to remove fat in the uppermost layer After that, the mixture was heated to 30 ° C., an appropriate amount of chymosin was added, and the mixture was stirred for 2 hours, centrifuged (720 g × 30 min), and the supernatant was filtered through a membrane filter to obtain clear colostrum. 3 l of methanol was mixed with 5 l of this colostrum, adjusted to pH 3.0 with acetic acid, and further mixed for 2 hours with a homomixer. Thereafter, the supernatant was separated by decantation, concentrated twice by an ultrafiltration membrane having a molecular weight cut off of 10,000, and filtered through celite to obtain a clear colostrum fraction.
[0023]
Sample B Preparation of an extract containing a melanin production-inhibiting component extracted from molasses To 1 kg of molasses was added 5 l of a 70% aqueous methanol solution, and the mixture was extracted with stirring. The filtrate is concentrated under reduced pressure to remove methanol. To this, 41 g of water and 120 g of activated carbon are added and stirred for 1 hour. Next, this is filtered to obtain an extract 41.
[0024]
Sample C 4 l of water and 120 g of activated carbon were added to the insoluble matter obtained in the preparation process of sample B, followed by stirring for 1 hour. Next, this is filtered to obtain 4 l of extract.
[0025]
Sample B melanin production inhibitory effect test 2 × 10 5 B16 melanoma cells were placed in a culture dish of 6 cm in diameter using an Eagle MEM medium supplemented with fetal bovine serum containing 5 ml of sample B at 37 ° C. in air containing 5% carbon dioxide gas. Cultured for 7 days. Thereafter, the cells were detached with a Dulbecco's phosphate buffer containing 0.025% trypsin, the number of cells was measured, and the degree of whitening of the cells obtained by centrifugation was visually observed. As a control, sterilized purified water was used in place of sample B. As shown in Table 1, there was almost no change in the number of cells between the sample-added group and the control, but the whiteness was markedly whitened in the sample-added group, but hardly increased in the control. There was no change. This confirms that Sample B is an extract containing a melanin production-inhibiting component extracted from molasses.
On the other hand, it is understood that the 70% methanol-insoluble matter of molasses does not contain a melanin production inhibitory component.

Test Example 1 Collagen Synthesizing Ability Test of Cultured Fibroblasts WI-38 cells (human fetal lung normal diploid cells PDL40) that had been subcultured were cultured in a new MEM medium (containing 10% fetal bovine serum) the day before the test. After exchanging and culturing for 24 hours (preculture), a sample was added to the culture supernatant, [ 3 H] -proline was added to a final concentration of 2 μCi, and cultivation was performed at 37 ° C. for 5 hours with 5% CO 2 + 95% Air. did. In addition, the sample non-addition section was targeted. Thereafter, the culture supernatant was removed, and 5 units / ml of collagenase type (manufactured by Worthington) was allowed to act on the cell fraction at 37 ° C. for 18 hours, deproteinized with a trichloroacetic acid solution, and [ 3 H]- The amount of proline was counted using a scintillator to determine the amount of collagen. The non-collagen protein content, collagenase total [3 H] untreated - expressed as a value obtained by subtracting the amount of collagen proline amount. Table 2 shows the types of the samples added to the medium, the amounts of the samples added, and the test results.

As is clear from Table 2, when a collagen synthesis enhancer derived from bovine colostrum and an extract containing a melanin production-inhibiting component extracted from molasses are simultaneously added, the effect of the collagen synthesis enhancer to significantly enhance the ability to promote collagen synthesis is demonstrated. It is understood that there is. As can be seen from the test plots 7 and 8, the extract containing no melanin production-inhibiting component (in this case, methanol-insoluble matter) extracted from molasses has no effect of promoting collagen synthesis itself, and the collagen synthesis enhancer collagen synthesis It is understood that there is no effect of enhancing the enhancing ability.

【The invention's effect】
As described above in detail, a skin cosmetic comprising the collagen synthesis enhancer derived from mammalian whey according to the present invention and an extract containing a melanin production-inhibiting component extracted from molasses, Compared to using a collagen synthesis enhancer of origin alone, when an extract containing a melanin production inhibitory component extracted from molasses is simultaneously added, the collagen synthesis enhancer of the collagen synthesis enhancer is synergistically enhanced. It is effective. In particular, only the extract containing a melanin production-inhibiting component extracted from molasses does not have a collagen synthesis-enhancing effect, but by being included in a collagen synthesis enhancer derived from mammalian whey, the collagen synthesis-enhancing agent is It has a unique effect of synergistically increasing its ability to enhance collagen synthesis. Further, the molasses extract according to the present invention to be added at the same time is, of course, an extract containing a melanin production-inhibiting component. There are advantages that can be manifested.
