Abstract

PROBLEM TO BE SOLVED: To provide an external preparation for skin, suitable for preventing wrinkle formation and rough skin by promoting collagen production, specifically by promoting collagen production in human skin fibroblasts.SOLUTION: The inventors have found that a conchiolin hydrolysate is effective to promote collagen production and have expanded its use. They also have found that, when used as an origin of conchiolin, black-lip pearl oysters are effective to promote collagen production.

Description

本発明はコラーゲン産生促進剤に関し、詳細には、ヒト皮膚線維芽細胞のコラーゲン産生を促進させることにより、シワ形成の予防、肌荒れ防止等に好適な皮膚外用剤に関する。   The present invention relates to a collagen production promoter, and in particular, to a skin external preparation suitable for preventing wrinkle formation and preventing rough skin by promoting collagen production of human skin fibroblasts.

皮膚の構造を支持する成分にはエラスチン、コラーゲン、ヒアルロン酸、コンドロイチン硫酸、ヘパラン硫酸、デルマタン硫酸、ラミニン等があり、皮膚の柔軟性、弾力性、水分保持がなされ、外見的にもハリや艶のあるみずみずしい状態を呈する。
しかし、老化、光等による、皮膚構造支持物質の減少や構造の変化により、期待する皮膚の柔軟性、弾力性、水分が失われなされ、外見的にもハリや艶のあるみずみずしい状態が保たれない。
このなかでも、コラーゲンは重要な役割を持ち、コラーゲンを配合した製品は勿論、皮膚中でのコラーゲン産生を促進する物質を配合した皮膚外用剤も上梓されている。
Ingredients that support the structure of the skin include elastin, collagen, hyaluronic acid, chondroitin sulfate, heparan sulfate, dermatan sulfate, laminin, etc. It has a fresh state with no.
However, due to aging, light, etc., the decrease in skin structure-supporting substances and changes in structure result in the loss of expected skin flexibility, elasticity, and moisture, and the appearance of the skin is refreshing and glossy. Absent.
Among these, collagen plays an important role, and not only products containing collagen, but also external preparations for skin containing substances that promote collagen production in the skin are listed.

コンキオリンは真珠層を形成する蛋白質を主成分とする物質で、真珠蛋白とも呼ばれ、真珠あるいは貝殻の真珠光沢に関与している。
コンキオリンは必要に応じて加水分解され、化粧品、食品、医薬品に利用されており、皮膚の外用剤等での効果としては、ヒスタミン抑制、活性酸素抑制、抗炎症、損傷治癒、皮膚角化促進が知られている。(特許文献1〜5)
Conchiolin is a substance mainly composed of a protein that forms a pearl layer, also called a pearl protein, and is involved in the pearl luster of pearls or shells.
Conchiolin is hydrolyzed as needed, and is used in cosmetics, foods, and pharmaceuticals. The effects of topical skin preparations include histamine suppression, active oxygen suppression, anti-inflammation, damage healing, and promotion of skin keratinization. Are known. (Patent Documents 1 to 5)

本発明の目的は、安全で、シワ形成予防や弾力のある皮膚を得るためのコラーゲン産生促進作用を有する製剤を得ることにある。   An object of the present invention is to obtain a preparation having a collagen production promoting action for obtaining a safe, wrinkle-preventing and elastic skin.

本発明者らが鋭意検討した結果、コンキオリンの加水分解物が上記目的を達することがわかった。
コンキオリンは、アコヤガイ、クロチョウガイ、シロチョウガイ、マベ、アワビ、イケチョウガイ等の真珠または貝殻の真珠層に含まれるので、これらの真珠あるいは貝殻から炭酸カルシウムを除いた(脱灰)のちに加水分解することによって、コンキオリンの加水分解物が得られる。
脱灰は酸類(通常は安価な塩酸がもっともよく利用されるが)で、水不溶性の炭酸カルシウムから塩化カルシウム等の水によく溶解する物質に変化させ、デカンテーション、遠心分離、濾過等の方法で、不溶のコンキオリンと分ける。コンキオリン以外の物質も不溶物の中に含まれるが特に問題ない。
このコンキオリンを酸、アルカリや蛋白分解酵素で分解する。コンキオリンは通常、蛋白分解酵素では分解しないので、酸やアルカリで分解するが酸を用いることが一般的である。
酸は、塩酸、硫酸、リン酸、乳酸、蟻酸、シュウ酸、マレイン酸、サリチル酸、酒石酸、フマル酸、クエン酸、リンゴ酸、コハク酸が例示され、この中から1種以上を選択して加水分解する。また、酸加水分解した後、蛋白分解酵素でさらに分解することもできる。
必要な加水分解を行ったら、酸を用いた場合は中和し、製剤として用いやすいようにpHを中性付近にしておく。中和剤としては特に限定はないが、水酸化ナトリウム、水酸化カリウム等が一般的に利用される。
中和すると塩が生じるので、場合によっては製剤を作成する場合に障害になるので塩を除く操作を行う。
脱塩の方法は特に限定はなく、イオン交換樹脂、電気透析等の方法がある。しかしコストがかかるので、特開昭62−223104号公報や特願2012−148228号等の方法を取ると安価にそして不純物も減少させたコンキオリンの加水分解物を得ることができる。
As a result of intensive studies by the present inventors, it was found that a hydrolyzate of conchiolin achieves the above object.
Conchiolin is contained in the nacreous layer of pearls or shells such as pearl oysters, black butterflies, white butterflies, abalone, and skeletal oysters. A hydrolyzate of conchiolin is obtained.
Decalcification is an acid (usually cheap hydrochloric acid is most commonly used), but it is changed from water-insoluble calcium carbonate to a substance that dissolves well in water, such as calcium chloride, and decantation, centrifugation, filtration, etc. Separate it from insoluble conchiolin. Substances other than conchiolin are also included in the insoluble matter, but there is no particular problem.
This conchiolin is decomposed with acid, alkali or proteolytic enzyme. Since conchiolin is not normally decomposed by proteolytic enzymes, it is generally decomposed with acid or alkali, but acid is generally used.
Examples of the acid include hydrochloric acid, sulfuric acid, phosphoric acid, lactic acid, formic acid, oxalic acid, maleic acid, salicylic acid, tartaric acid, fumaric acid, citric acid, malic acid, and succinic acid. Decompose. Further, after acid hydrolysis, it can be further decomposed with a proteolytic enzyme.
After the necessary hydrolysis, the acid is neutralized when it is used, and the pH is kept near neutral so that it can be easily used as a preparation. Although there is no limitation in particular as a neutralizing agent, Sodium hydroxide, potassium hydroxide, etc. are generally utilized.
When neutralized, a salt is formed. In some cases, it becomes an obstacle when preparing a preparation.
There is no particular limitation on the desalting method, and there are methods such as ion exchange resin and electrodialysis. However, since the cost is high, it is possible to obtain a hydrolyzate of conchiolin at a low cost and with reduced impurities by adopting methods such as JP-A-62-2223104 and Japanese Patent Application No. 2012-148228.
