Description
本発明は、塗布時にべた付きが少なく、肌にしっとり感を付与し、かつ保湿効果の持続性を実感でき、使用感にも優れた化粧料組成物に関するものである。 TECHNICAL FIELD The present invention relates to a cosmetic composition which is less sticky when applied, imparts a moist feeling to the skin, allows the user to feel the persistence of the moisturizing effect, and is excellent in feeling of use.
従来、皮膚や毛髪用の化粧料には、水分を保持し、かさつき感やぱさつき感を抑えしっとり感を与える目的として、グリセリンや１，３－ブチレングリコール（１，３－ＢＧ）等の水溶性多価アルコールや、ムコ多糖類のヒアルロン酸ナトリウム等の水溶性高分子が保湿剤として用いられている。一方で、天然保湿因子の構成成分であるアミノ酸やアミノ酸誘導体であるピロリドンカルボン酸ナトリウムは、安全性の高い保湿剤として注目されている。さらに、保湿力及び吸湿力に優れた保湿剤として、ポリアスパラギン酸塩の配合が提案されている（特開平６－１５７２３７号公報）。
しかしながら、ポリアスパラギン酸塩はその保湿効果が充分なものとは言えず、多量に配合すると、皮膚に塗布した際にべたつきが生じ、使用感を損ねるという欠点があった。このような問題を解決するために、以下のような解決案が提案されている。
すなわち、塗布時のべたつきが少なく、肌へのなじみを良くするために、アミノ酸及びその塩、ピロリドンカルボン酸及びその塩並びにグリシンベタインからなる群より選ばれる化合物を併用することが提案されている（特開平７－２７７９１６号公報）。
また、べたつきが少なく、肌にすべすべ感を付与するために、リン脂質、液状油、水溶性保湿剤を併用することが提案されている（特開２０００－１０３７２７号公報）。
しかしながら、これらの技術では、保湿効果を持続的に実感することや、塗布時のべたつきを抑え、しっとり感を付与するには、十分に満足するものではない。
また、グリシルグリシンやアラニルグルタミン等についても、保湿剤としての効果が知られている（特開２００６－２９８７９６号公報、特許３６２３５４８号公報）が、これらの保湿剤は肌との馴染みが良くなく、角層への浸透性に劣る。Conventionally, water-soluble ingredients such as glycerin and 1,3-butylene glycol (1,3-BG) have been used in cosmetics for skin and hair for the purpose of retaining moisture and giving a moist feeling by suppressing dryness and dryness. Polyhydric alcohols and water-soluble polymers such as sodium hyaluronate, which is a mucopolysaccharide, are used as moisturizing agents. On the other hand, sodium pyrrolidone carboxylate, which is an amino acid or an amino acid derivative, which is a component of natural moisturizing factors, is attracting attention as a highly safe moisturizing agent. Further, as a moisturizing agent having excellent moisturizing power and hygroscopic power, the blending of polyaspartate has been proposed (Japanese Unexamined Patent Publication No. 6-157237).
However, it cannot be said that the moisturizing effect of polyaspartate is sufficient, and when it is blended in a large amount, it has the drawback of causing stickiness when applied to the skin and impairing the feeling of use. In order to solve such problems, the following solutions have been proposed.
In other words, it has been proposed to use a compound selected from the group consisting of amino acids and their salts, pyrrolidone carboxylic acid and its salts, and glycine betaine in combination in order to reduce stickiness upon application and improve skin compatibility ( Japanese Patent Laid-Open No. 7-277916).
Also, in order to impart a smooth feel to the skin with little stickiness, it has been proposed to use a phospholipid, a liquid oil, and a water-soluble moisturizing agent in combination (Japanese Unexamined Patent Application Publication No. 2000-103727).
However, these techniques are not fully satisfactory in achieving a sustained moisturizing effect, suppressing stickiness during application, and imparting a moist feeling.
Glycylglycine, alanylglutamine and the like are also known to be effective as moisturizing agents (Japanese Patent Application Laid-Open No. 2006-298796, Japanese Patent No. 3623548), but these moisturizing agents are familiar with the skin. and poor penetration into the stratum corneum.
本発明は、塗布時にべた付きが少なく、肌にしっとり感を付与し、かつ保湿効果の持続性を実感でき、使用感にも優れた化粧料を提供することを目的とする。 An object of the present invention is to provide a cosmetic that is less sticky when applied, imparts a moist feeling to the skin, allows a user to feel the persistence of the moisturizing effect, and has an excellent feeling of use.
