Description

本発明は、バリア機能向上、及び表皮水分保持能に優れた構造組成物である保湿剤、及びこれを含有する皮膚外用剤に関する。   The present invention relates to a moisturizing agent which is a structural composition excellent in barrier function improvement and epidermal moisture retention ability, and a skin external preparation containing the same.

肌の最外層にある角質層は、水分保持機能と、バリア機能とよばれる肌内部からの水分蒸散を防いで、外部刺激から肌を守るという2つの働きをもつことが知られている。皮膚炎や乾癬、アトピー性皮膚炎等に見られる数々の皮膚疾患の肌荒れ症状においては、皮膚からの水分消失が、健常な皮膚に比べて盛んであることが知られており、いわゆる経表皮水分損失量(TEWL)の増加は、表皮で水分保持機能やバリア機能を担っている成分の減少が関係するものと考えられている。   It is known that the stratum corneum, which is the outermost layer of the skin, has two functions of preventing moisture evaporation from the inside of the skin called a moisture retention function and a barrier function and protecting the skin from external stimuli. It is known that water loss from the skin is more prominent than healthy skin in rough skin symptoms of numerous skin diseases such as dermatitis, psoriasis, and atopic dermatitis. The increase in the amount of loss (TEWL) is considered to be related to the decrease in the components responsible for the moisture retention function and the barrier function in the epidermis.

従来より、皮膚疾患や肌荒れに対して改善・予防効果を有する有効成分として、水分保持機能や皮膚バリア機能を担う表皮内成分を皮膚に補充するという観点から、NMF(Natural Moisturizing Factor)としてのアミノ酸や、セラミドなどの表皮角質細胞間脂質を外部から供給する目的で、化粧料や皮膚外用剤に配合し、これを皮膚に継続的に適用することにより、角質水分保持能が回復し、皮膚の状態を健やかに保つことはよく知られている。   Amino acids as NMF (Natural Moisturizing Factor) from the viewpoint of replenishing the skin with components in the epidermis responsible for moisture retention and skin barrier functions as active ingredients that have an effect of improving and preventing skin diseases and rough skin. For the purpose of supplying keratin intercellular lipids such as ceramide from the outside, it is incorporated into cosmetics and topical skin preparations, and this is continuously applied to the skin. It is well known to keep the state healthy.

表皮角質細胞間脂質は、脂質ニ重層が幾重にも重なり、規則正しく整列したラメラ構造を形成していることから、生体内でバリア機能を発揮するものであり、このようなラメラ構造を有するものであれば、生体成分でなくても同様の作用を有することはわかっている。もともと肌荒れ症状は、皮膚からの水分の損失が健常皮膚に対し大きいために生じるもので、水分を長時間保持することで、肌荒れは改善に向かう。そこで、表皮角質細胞間脂質と同様の機能を発揮する成分が求められてきた。   Epidermal stratum corneum lipids exhibit a lamellar structure in which the lipid bilayers overlap and form a regularly arranged lamellar structure, and thus exhibit a barrier function in vivo, and have such a lamellar structure. If it exists, it is known that it has the same effect even if it is not a biological component. Originally, rough skin symptoms are caused by the loss of moisture from the skin, which is greater than that of healthy skin. By holding the water for a long time, rough skin tends to improve. Therefore, there has been a demand for a component that exhibits the same function as that of epidermal keratinocytes.

自己ラメラ形成能のあるステロール脂肪酸エステル類が、角質水分含量保持能に優れた保湿性能を有し、これを配合することにより保湿作用に優れ、かつ使用感の良好な化粧料や、乾燥に起因する皮膚疾患の治療薬が得られる(特許文献1参照)ことが知られている。また特定の混合分岐脂肪酸コレステリルと水素添加レシチンとジアルキルエーテルを配合とを配合することで(特許文献2参照)、分岐脂肪酸コレステリルを安定に製剤中に配合するとともに、この三者が相乗的に皮膚に作用して、皮膚の乾燥を予防することにより、肌目(きめ)を細かなかつしっかりとした皮膚にする(美肌効果)と共に、優れた皮膚老化防止効果等、顕著な効果を表すことも知られている。ステロール脂肪酸エステルの中で、分岐脂肪酸フィトステリルは、単独でラメラ液晶構造体を形成することができ、単独で水分保持機能を有することはよく知られている。   Sterol fatty acid esters with the ability to form self-lamellar have a moisturizing performance with an excellent ability to retain keratin water content, and by incorporating this, cosmetics with excellent moisturizing action and good feeling of use, and due to drying It is known that a therapeutic drug for skin diseases can be obtained (see Patent Document 1). In addition, by blending a specific mixed branched fatty acid cholesteryl, hydrogenated lecithin, and dialkyl ether (see Patent Document 2), the branched fatty acid cholesteryl is stably blended in the preparation, and these three members synergistically It works to prevent skin dryness to make the skin texture (fine texture) fine and firm (beautifying skin effect), and also exhibits outstanding effects such as excellent skin aging prevention effect. It has been. Among the sterol fatty acid esters, it is well known that the branched fatty acid phytosteryl can form a lamellar liquid crystal structure alone and has a water retention function alone.
