Description
本発明は、乳化化粧料に関する。 The present invention relates to an emulsified cosmetic.
α−ゲルは、水和型の結晶構造であり、ラメラ構造を有する。皮膚最外層の角層に存在する角層細胞間脂質も、その大半がこのα−ゲル構造をとっており、皮膚に対して、外部からの物質の侵入、内部からの水分蒸散を抑制すると同時に、そのもの自身が水分を保持することで、皮膚の柔軟性やなめらかな外観を保つ機能を有している。そこで、保湿効果を得るための化粧料などとして、液晶構造を形成する組成物が検討されているが、α−ゲルを形成する組成物は、皮膚に塗布後、経時でべたつきが生じるという課題があった。 α-gel is a hydrated crystal structure and has a lamellar structure. Most of the stratum corneum intercellular lipids present in the outermost stratum corneum also have this α-gel structure, and at the same time suppress the invasion of substances from the outside and the evaporation of moisture from the inside to the skin. , By itself retaining moisture, it has the function of maintaining the skin's flexibility and smooth appearance. Therefore, as a cosmetic for obtaining a moisturizing effect, a composition that forms a liquid crystal structure has been studied. However, a composition that forms an α-gel has a problem that stickiness occurs over time after being applied to the skin. there were.
このため、α−ゲルに粉体を配合して、さらさら感を得ることが検討されている（特許文献１）。
また、特許文献２には、ＨＬＢ１０以下の界面活性剤を用いてラメラ液晶構造を形成させ、粉体を配合した化粧料が記載されている。
For this reason, it has been studied to obtain a smooth feeling by blending powder into α-gel (Patent Document 1).
Patent Document 2 describes a cosmetic in which a lamellar liquid crystal structure is formed using a surfactant having an HLB of 10 or less and a powder is blended.
しかしながら、特許文献１に記載されている組成物は、塗布時には液晶構造が壊れ、αゲル被膜は形成されないため、粉体を均一に付着させることは難しく、高い保湿効果とべたつきのなさの持続を両立させることも困難である。また、特許文献２に記載されている組成物は、ラメラ液晶構造と粉体のかかわりについての具体的な効果の記載はない。 However, the composition described in Patent Document 1 breaks the liquid crystal structure at the time of application, and the α gel film is not formed. Therefore, it is difficult to uniformly apply the powder, and the high moisturizing effect and non-stickiness are maintained. It is difficult to achieve both. Moreover, the composition described in Patent Document 2 does not describe a specific effect regarding the relationship between the lamellar liquid crystal structure and the powder.
本発明は、皮膚に塗布した際、皮膚表面に粉体を含む柔軟なラメラ状のα−ゲル構造の皮膜を形成し、粉体が均一に付着して摩擦に対しても取れにくく、高い保湿効果とべたつきのなさが持続する乳化化粧料に関する。 The present invention forms a soft lamellar α-gel structure film containing powder on the skin surface when applied to the skin, and the powder adheres uniformly and is difficult to remove against friction, and is highly moisturizing. The present invention relates to an emulsified cosmetic that maintains its effectiveness and non-stickiness.

本発明において、成分（Ｆ）の水は、乳化化粧料中の溶剤として使用され、乳化化粧料を構成する前記成分及びその他成分の残部となる。含有量は、全組成中に、５０質量％以上が好ましく、６０質量％以上がより好ましく、９８質量％以下が好ましく、９５質量％以下がより好ましい。成分（Ｆ）は、本発明の乳化化粧料を塗布乾燥後、成分（Ａ）〜（Ｄ）及び（Ｆ）で構成される皮膜に柔軟性を付与する働きがあり、皮膚に追従する皮膜形成が可能となる。更に、成分（Ｅ）が皮膜から落ちにくくする効果もある。 In this invention, the water of a component (F) is used as a solvent in emulsified cosmetics, and becomes the remainder of the said component and other components which comprise emulsified cosmetics. The content is preferably 50% by mass or more, more preferably 60% by mass or more, preferably 98% by mass or less, and more preferably 95% by mass or less in the entire composition. Component (F) has a function of imparting flexibility to the film composed of components (A) to (D) and (F) after applying and drying the emulsified cosmetic of the present invention, and forms a film that follows the skin. Is possible. Furthermore, there is an effect that the component (E) is less likely to fall off the film.
本発明の乳化化粧料は、成分（Ｅ）の粉体を皮膚に均一に塗布することが可能である。これは、従来の乳化化粧料とは異なる性能である。例えば、水中油型乳化物に、粉体が分散された系では、該乳化物を皮膚に塗布すると油滴と連続相である水が皮膚表面に付き、水が乾燥すると油滴が、島状になって皮膚に残る。粉体は、この状態で皮膚上に残り、油滴に付着することになる。すると、油滴が、不均一に肌に残ることになるので、粉体も不均一に肌に残ることになる。一方、本発明の乳化化粧料は、乳化化粧料自体が、ラメラ構造を有する液状又はクリーム状となっており、塗布乾燥後、皮膚表面を、αゲル構造をなす皮膜が均一に覆う。従って、ラメラ構造を有することによって粉体は、どこでも皮膚に付着できることになり、粉体の均一塗布が可能となることを見出した。 The emulsified cosmetic of the present invention can uniformly apply the powder of component (E) to the skin. This is a performance different from conventional emulsified cosmetics. For example, in a system in which powder is dispersed in an oil-in-water emulsion, when the emulsion is applied to the skin, water that is in a continuous phase with the oil droplets adheres to the skin surface, and when the water dries, the oil droplets form islands. And remains on the skin. In this state, the powder remains on the skin and adheres to the oil droplets. Then, since oil droplets will remain unevenly on the skin, the powder will also remain unevenly on the skin. On the other hand, in the emulsified cosmetic of the present invention, the emulsified cosmetic itself is in the form of a liquid or cream having a lamellar structure, and after coating and drying, the skin forming the α gel structure uniformly covers the skin surface. Therefore, it has been found that the powder can adhere to the skin everywhere by having a lamellar structure, and the powder can be uniformly applied.

成分（Ｇ）は、１種又は２種以上を用いることができ、含有量は、皮膚表面にできた皮膜の柔軟性及び使用感の点から、１質量％以上が好ましく、３質量％以上がより好ましく、３０質量％以下が好ましく、２０質量％以下がより好ましい。また、成分（ＧＦ）の含有量は、全組成中に１〜３０質量％が好ましく、３〜２０質量％がより好ましい。

Component (G) can be used singly or in combination of two or more, and the content is preferably 1% by mass or more, preferably 3% by mass or more from the viewpoint of the flexibility of the film formed on the skin surface and the feeling of use. More preferably, it is preferably 30% by mass or less, and more preferably 20% by mass or less. Moreover, 1-30 mass% is preferable in the whole composition, and, as for content of a component (GF), 3-20 mass% is more preferable.
