Description

【0001】
【発明の属する技術分野】
本発明は、肝細胞増殖因子であるHGFの産生促進剤およびこのHGF産生促進剤を含有する抗老化、肌荒れ改善および育毛効果を持つ化粧料に関する。
【0002】
【従来の技術】
細胞増殖因子は、生体の秩序ある構築や恒常性の維持に重要な役割を果たしており、作用異常はしばしば病気につながることが知られている。これら増殖因子の中でも、HGF(肝細胞増殖因子)は主臓器由来の上皮細胞を中心に、血管内皮細胞や造血系、神経系に働き、多岐の細胞賦活作用を示す(非特許文献1参照)。皮膚においても、上皮細胞である角化細胞(非特許文献2参照)、毛母および毛包細胞(非特許文献3参照)や直下の血管内皮細胞に働き(非特許文献4参照)、皮膚の賦活化に関与している。これらの細胞を賦活し、抗老化、肌荒れ改善および育毛効果を求めることを目的とした細胞増殖因子の直接投与により、効果が進む一方、副作用として生体にとって過剰な因子の影響により細胞障害を生じることもある(非特許文献5参照)。よって、HGFなどの細胞増殖因子を化粧料に配合し、用いることは困難であった。一方、HGFを生体に直接投与するのではなく、生体が本来持っているHGFの産生を促進させることにより、上皮細胞の賦活作用を高めることが期待できるものの、HGFの産生を促進させる成分は知られていなかった。また、米抽出物の化粧料への利用としては、養毛剤としての特許文献1や皮膚に対して効果の高い特許文献2および3が知られているものの、HGFの産生促進については言及されていなかった。

【発明が解決しようとする課題】
HGF配合による化粧料は、副作用として生体にとって過剰な因子の影響により細胞障害を生じるため、安全性上問題が多い。
【0005】
そこで、HGFを作り出す間質系細胞中の産生量を増加させ周りの細胞を賦活することにより、優れた皮膚の抗老化、肌荒れ改善および育毛効果を示し、かつ副作用なく安全性の高いHGF産生促進剤やそれを配合した化粧料の開発が望まれていた。
【0006】
【課題を解決するための手段】
このような事情により、本発明者らは皮膚の抗老化、肌荒れ改善および育毛効果を目的に鋭意検討した結果、米の抽出物が間質系細胞である線維芽細胞や毛乳頭細胞自身の持つHGFの産生作用を促進させ、このHGFが上皮系細胞である角化細胞、毛母および毛包細胞を賦活することにより、優れた皮膚の抗老化、肌荒れ改善および育毛効果を示すことを見出し、本発明を完成するに至った。
【0007】
すなわち、本発明は、米抽出物およびそれを含有する皮膚の抗老化、肌荒れ改善および育毛化粧料である。
【0008】
本発明にて用いられる米としては、産地を問わず、白米や有色米である黒米、赤米等が挙げられ、それらの玄米、糠、胚芽等を利用できる。抽出物として、これらのうち、一種または二種以上を組み合わせても良い。
【0009】
抽出する溶媒としては、例えば、水、低級アルコール類(メタノール、エタノール、1−プロパノール、2−プロパノール、1−ブタノール、2−ブタノール等)、液状多価アルコール(グリセリン、プロピレングリコール、1,3−ブチレングリコール等)、ケトン類(アセトン、メチルエチルケトン等)、アセトニトリル、エステル類(酢酸エチル、酢酸ブチル等)、炭化水素類(ヘキサン、ヘプタン、流動パラフィン等)、エーテル類(エチルエーテル、プロピルエーテル、テトラヒドロフラン等)が挙げられる。好ましくは、水、低級アルコールおよび液状多価アルコールが良く、特に好ましくは、水、エタノール、プロピレングリコールおよび1,3−ブチレングリコールが良い。これらの溶媒は一種でも二種以上を混合して用いても良い。
【0010】
これらは抽出した溶液のまま用いても良く、必要に応じて、濃縮、希釈、濾過等の処理および活性炭等による脱色、脱臭処理をして用いても良い。さらには、抽出した溶液を濃縮乾固、噴霧乾燥、凍結乾燥等の処理を行い、乾燥物として用いても良い。
【0011】
本発明に用いる抽出物の化粧料への配合量は、特に限定されていないが、好ましくは本発明における全量に対し、固形分に換算して0.0001重量%以上が良く、さらに好ましくは0.0005〜10重量%が良い。0.0001重量%未満では十分な効果は発揮され難い。10重量%を越えて配合した場合、効果の増強は少なく不経済である。また、添加の方法については、予め加えておいても、製造途中で添加しても良く、作業性を考えて適宜選択すれば良い。
【0012】
本発明の抽出物の効果を損なわない範囲内で、通常の化粧品および医薬部外品に用いられる抽出物である油脂類、ロウ類、炭化水素類、脂肪酸類、アルコール類、エステル類、界面活性剤、金属石鹸、pH調整剤、防腐剤、香料、保湿剤、粉体、紫外線吸収剤、増粘剤、色素、酸化防止剤、美白剤、キレート剤等の抽出物を配合することもできる。
【0013】
本発明の抽出物は、化粧品、医薬部外品および医薬品のいずれにも用いることができ、その剤型としては、例えば、化粧水、クリーム、乳液、ゲル剤、エアゾール剤、エッセンス、パック、洗浄剤、浴用剤、ファンデーション、打粉、口紅等が挙げられる。
【0014】
【実施例】
次に本発明を詳細に説明するため、実施例として本発明に用いる抽出物の製造例、本発明の処方例および実験例を挙げるが、本発明はこれに限定されるものではない。実施例に示す配合量の部とは重量部を、%とは重量%を示す。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an agent for promoting the production of HGF, which is a hepatocyte growth factor, and to a cosmetic containing the agent for promoting aging, improving skin roughness and improving hair growth.
[0002]
[Prior art]
Cell growth factors play an important role in orderly construction and maintenance of homeostasis in living organisms, and it is known that abnormal action often leads to disease. Among these growth factors, HGF (hepatocyte growth factor) acts on vascular endothelial cells, hematopoietic system, and nervous system, mainly on epithelial cells derived from main organs, and has various cell activating effects (see Non-Patent Document 1). . In the skin, it acts on keratinocytes, which are epithelial cells (see Non-Patent Document 2), hair matrix and hair follicle cells (see Non-Patent Document 3), and vascular endothelial cells immediately below (see Non-Patent Document 4). Involved in activation. By direct administration of cell growth factor for the purpose of activating these cells and seeking anti-aging, improvement of skin roughness and hair growth effect, while the effect progresses, the side effect may cause cell damage due to excessive factors for the living body (See Non-Patent Document 5). Therefore, it has been difficult to mix and use cell growth factors such as HGF in cosmetics. On the other hand, it is expected that the activation of epithelial cells can be enhanced by promoting the production of HGF inherent in the living body instead of directly administering HGF to the living body, but the components that promote the production of HGF are not known. Had not been. As for the use of rice extract in cosmetics, Patent Literature 1 as a hair restorer and Patent Literatures 2 and 3 which are highly effective on the skin are known, but no mention is made of the promotion of HGF production. Was.

Next, experimental examples will be described in order to explain the effects of the present invention in detail.
[0031]
Experimental Example 1 HGF production promoting action in human dermal fibroblasts In a case where 10 and 100 μg / mL of the hot water extract of black rice bran of Production Example 1 were added to cultured human dermal fibroblasts (NB1RGB: RIKEN). The effect of promoting HGF production was examined. The amount of HGF produced was determined by the enzyme antibody method (A'NAYZA HUMAN HGF kit), and the cell viability was measured by absorbance as the amount of neutral red uptake. In each case, the evaluation was made at a ratio of 100 when no additive was added.
[0032]
As a result, as shown in Table 1, the amount of HGF production increased by 410% or more at a concentration of 10 µg / mL or more in the treatment with the hot water extract of black rice bran.
[0033]

[0037]
Each of the cosmetics obtained in Examples 2 to 7 showed a sufficient effect of improving skin abrasion and rough skin.
[0038]
Experimental Example 3 HGF production promoting action on human hair papilla cells The HGF production promoting action was investigated when 100 μg / mL of the black rice bran hexane extract of Production Example 7 was added to cultured human hair papilla cells (manufactured by Toyobo). The amount of HGF produced was determined by an enzyme-linked immunosorbent assay and the cell viability was measured by absorbance as the amount of neutral red uptake. The cell viability was evaluated at a ratio of 100 when no addition was made.
[0039]
As a result, as shown in Table 3, the amount of HGF produced was detected at 0.23 ng / mL in the treatment with the black rice bran hexane extract. Since no HGF could be detected in the control, the rate of increase could not be calculated. The cell viability increased and it was considered that there was also a cell proliferation effect.
