【発明の属する技術分野】
本発明は、安全性、保湿効果に優れ、皮膚のハリ、タルミ、キメ改善に優れる皮膚化粧料に関する。
【0002】
【従来の技術及び課題】
老化した皮膚では、表皮及び真皮の細胞活性の低下が見られ、そのため角質層の機能低下による乾燥肌や真皮線維芽細胞の機能低下による弾力性のない肌になる。その結果、高齢者の皮膚は、ハリがなく、たるんだ状態になりがちである。このような老化皮膚の活性を回復させるために、細胞賦活剤の探索が行われ、カバノキ科のカバノキ属に属するシラカンバ、ハンノキ属に属するハンノキの抽出エキスに表皮細胞の増殖を顕著に促進し、角質層の機能を改善する作用があることが開示されている。(特開平6−263627号公報)
【0003】
【発明が解決しようとする課題】
したがって、さらに皮膚のハリ、キメ、たるんだ状態、あるいは角質層の機能を改善するための皮膚化粧料の開発が待ち望まれている。
【0004】
【課題を解決するための手段】
本発明者は、皮膚のハリ、タルミ、キメ改善向上させるべく鋭意研究を重ねたところ、カバノキ科のカバノキ属に属する植物、又はハンノキ属に属する植物の抽出エキスと、ホエイを配合することにより、皮膚のハリ、タルミ、キメが相乗的に改善、向上することを見出し、本発明の完成に至った。
【0005】
【発明の実施の形態】
本発明に用いるカバノキ科カバノキ属植物抽出物は、例えばシラカンバ(Betula platyphylla var. japonica)、コウアンシラカンバ(Betula platyphylla var.platyphylla)、シセンカンバ(Betula platyphylla var. szechanica)、ヨーロッパシラカンバ(Betula pendula)、ケカンバ(Betula pubescens)、トルトーサカンバ(Betula pubescens var. tortuosa)、イベリアカンバ(Betula certiberica)、ベトゥラ・パピリフィラ(Betula papyrifera)、ベトゥラ・ケナイカ(Betula kenaica)、ベトゥラ・ポプリフォリア(Betula populifplia)等からの抽出物である。また、同科のハンノキ属植物抽出物は、例えばハンノキ(Alnus japonica)、エゾハンノキ(ヤチハンノキ)(Alnus japonica var. arguta)、サクラバハンノキ(Alnus trabeculosa)、ネパールハンノキ(Alnus nepalensis)、ケヤマハンノキ(Alnus hirsuta)、ヤマハンノキ(Alnus hirsuta var. sibirica)、ヤハズハンノキ(Alnus matsumurae)、コバノヤマハンノキ(タニガワハンノキ)(Alnus inokumae)、カワラハンノキ(Alnus serrulatoides)等の抽出物である。これらの植物のうち、特にシラカンバ(Betula platyphylla var. japonica)、コウアンシラカンバ(Betula platyphylla var. platyphylla)、ヨーロッパシラカンバ(Betula pendula)が好ましい。

【0007】
これらの抽出物の配合量は、化粧料全量に対し0.001〜10重量%、特に0.01〜5重量%が好ましい。配合量が0.001重量%未満であると皮膚老化防止効果が十分に発揮できない。また、10重量%を超えて配合しても、それ以上のキメなどの改善効果が認められない。

BACKGROUND OF THE INVENTION
The present invention relates to a skin cosmetic that is excellent in safety and moisturizing effect, and is excellent in improving skin elasticity, talmi, and texture.
[0002]
[Prior art and problems]
In aged skin, cell activity of the epidermis and dermis is reduced, and therefore, dry skin due to a decrease in the function of the stratum corneum and inelastic skin due to a decrease in the function of dermal fibroblasts. As a result, the skin of the elderly tends to be in a sagging state without firmness. In order to restore the activity of such aging skin, a search for a cell activator was performed, and the birch belonging to the birch genus of the birch family, the extract of the alder belonging to the alder genus significantly promotes the proliferation of epidermal cells, It is disclosed that there is an effect of improving the function of the stratum corneum.

[0016]
The evaluation method is shown.
1. Practical evaluation (improvement of elasticity and tarmi)
Cream was applied to 20 female subjects twice a day (morning and evening) for 1 month, and the improvement of elasticity and tarmi after 1 month was evaluated as follows.
More than 15 people answered good: ◎
6-14 people who answered good: ○
Number of people who answered good is 5 or less: △
[0017]
2. Skin measurement evaluation (texture improvement effect)
The cream was applied to 20 female subjects twice a day (morning and evening) for 1 month, and the texture improvement effect after 1 month was measured. For the measurement, an image analysis method using a replica of the application site was used.
[0018]
The measurement method is shown. For each subject, a replica of the application part of the example (comparative example) was created, and these were observed with a microscope (HI-SCOPE MODEL KH-2200 MD2: manufactured by HIROX), and an image analysis apparatus (AVIO EXCEL: manufactured by NIPPON AVIONICS) Statistical analysis of the images taken in
[0019]
The texture improvement effect is expressed by labeling the number of textures within a certain area. Here, as the increase rate (%) of the texture (area surrounded by the skin groove on the image) within a certain area is larger, the texture improvement effect is higher.
[0020]
[Expression 1]
[0021]
[Table 1]
[0022]
As shown in Table 1, in the examples, improvements in elasticity and sagging were observed synergistically, and texture improvements were further observed synergistically.
[0030]
【The invention's effect】
According to the present invention, there is provided a skin cosmetic comprising whey in combination with an extract of a plant belonging to the genus Birchaceae of the family Birchaceae, or a plant belonging to the genus Alder for synergistic improvement of skin tension, tarmi and texture Can be provided.
