Description

【0001】
【発明の属する技術分野】
本発明は、小皺や毛穴等の肌上の微小な凹凸を自然にぼかし、目立たなくする化粧料(いわゆる、凹凸補正化粧料)に関するものであり、複数の略球状粒子が凝集合一し、表面に複数の凹凸を有する形状の異形複合粉体を含有することを特徴とする凹凸補正化粧料に関するものである。そして、更に詳細には、小皺や毛穴等の肌上の微小な凹凸を自然にぼかし、目立たなくさせる効果に優れ、伸び広がりが良好で、しかも経時的に肌から分泌される皮脂等により肌が油光する現象(いわゆる、テカリ現象)を防ぐ効果に優れた凹凸補正化粧料に関するものである。
【0002】
【従来の技術】
近年の高齢化社会において、いつまでも若々しい肌でいたいという女性のニーズにより、種々の凹凸補正効果を有する化粧料が開発されている。凹凸補正化粧料とは、メーキャップ化粧料の前後に、肌上の小皺や毛穴等の好ましくない微小な凹凸を目立たなくする特殊用途の化粧料や、好ましくない微小な凹凸を目立たなくする機能を付加したファンデーション、コンシーラー、下地料等のメーキャップ化粧料であり、多数の商品が発売され、市場で好評を得ている。
【0003】
これら従来の凹凸補正化粧料には、特定範囲の屈折率を有する粉体と高粘度のシリコ−ン油とを組み合わせた透明な組成物を、肌上の凹部に埋め込み、凹凸を平滑にする方法(例えば、特許文献1参照)や、特定の球状粉体を皮膜形成剤とともに肌上に配列させ、塗布膜表面での光散乱により肌の凹凸を見え難くする方法(例えば、特許文献2参照)等が用いられていた。
【0004】

【特許文献2】
特開2001−2530号公報(第1頁−第5頁)
【0005】
【発明が解決しようとする課題】
しかしながら、特定範囲の屈折率を有する粉体と高粘度のシリコ−ン油とを組み合わせた組成物を用いる方法では、シリコ−ン油が骨格となるため、シリコーン油特有の肌馴染みの悪さがあり、且つ、塗布時に粉体と高粘度シリコーン油との凝集体が発生し、いわゆる「ヨレ」を生じる場合があった。また、特定の球状粉体を皮膜形成剤とともに肌上に配列させ、塗布膜表面での光散乱により肌の凹凸を見え難くする方法は、皮膜形成成分を相当量配合しなければ、粉体を配列させることは不可能であり、その場合には、経時的に肌が油光するテカリ現象を生じる場合があった。
【0006】
このため、小皺や毛穴等の肌上の微小な凹凸を自然にぼかし、目立たなくさせる効果に優れ、伸び広がりが良好で、しかも経時的に肌が油光する現象を防ぐ効果に優れた凹凸補正化粧料の開発が望まれていた。
【0007】
【課題を解決するための手段】
かかる実情に鑑み、本発明者は鋭意検討した結果、複数の略球状粒子が凝集合一し、表面に複数の凹凸を有する形状の異形複合粉体が、伸び広がりに優れ、且つ、略球状粒子間の隙間に過剰な油剤や肌から分泌される皮脂等を吸着する特性に優れることを見出した。また、更に、該異形複合粉体は、表面に複数の凹凸を有するため、照射された光を多方向に散乱させる特性に優れるため、光学的にも、小皺や毛穴等の肌上の微小な凹凸を自然にぼかし、目立たなくさせる効果に優れることを見出した。そこで、これら知見に基づき、複数の略球状粒子が凝集合一し、表面に複数の凹凸を有する形状の異形複合粉体を凹凸補正化粧料に用いると、上記課題が解決されることを見出し、本発明を完成させた。
【0008】
すなわち、本発明は、複数の略球状粒子が凝集合一し、表面に複数の凹凸を有する形状の異形複合粉体を含有することを特徴とする凹凸補正化粧料を提供するものである。
【0009】
また、ポリアクリル酸アルキル及び/又はポリメタクリル酸アルキルとポリイソプレンを主成分とし、複数の略球状粒子が凝集合一し、表面に複数の凹凸を有する形状の異形複合粉体を含有する凹凸補正化粧料を提供するものである。
【0010】
【発明の実施の形態】
本発明の凹凸補正化粧料に用いられる異形複合粉体は、複数の略球状粒子が凝集合一したような、表面に複数の凹凸を有する形状の異形複合粉体(以下、「本発明の異形複合粉体」という)である。本発明の異形複合粉体における、略球状粒子とは、球状、楕円状等の概ね球に近い形状の粒子であり、その平均粒径は0.1〜10μmが好ましい。また、本発明の異形複合粉体は、一粒子中に前記略球状粒子が5〜30個凝集合一しているような形状が好ましい。そして、本発明の異形複合粉体は、前記略球状粒子が凝集合一している形状なので、略球状粒子間の隙間として凹部を形成し、略球状粒子自体で凸部を形成することにより、表面に複数の凹凸を有している。このような異形複合粉体は、例えば、図1に表されるような形状の粉体である。
【0011】
本発明の異形複合粉体の平均粒径は、特に限定されないが、1〜20μmが好ましく、更に5〜10μmが好ましい。更に、本発明の異形複合粉体のJIS K−5101により求めた、かさ(見かけ比容)は、特に限定されないが、2.5〜4.5mL/gが好ましく、JIS K−5101により求めた、煮アマニ油の吸油量は、特に限定されないが、60〜100mL/100gが好ましい。

【0014】
このような本発明の異形複合粉体は、市販品として、ポリアクリル酸アルキルとポリイソプレンの混合比(質量比)が95/5で、平均粒径8μm、かさ3.5mL/g、吸油量85mL/100gのガンツパ−ルGMI−0804(ガンツ化成社製)を用いることができる。尚、本市販品の形状は、図1に表されるような形状である。
【0015】
本発明の凹凸補正化粧料において、本発明の異形複合粉体は、照射された光を多方向に散乱させる特性に優れるため、肌上の微小な凹凸を自然にぼかし、目立たなくさせる肌の凹凸補正効果に優れる。また、本発明の異形複合粉体は、伸び広がりが良好であり、且つ、略球状粒子間の隙間に、過剰な油剤や肌から分泌される皮脂等を吸着する特性により、経時的なテカリ現象防止効果を有するものである。
【0016】

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a cosmetic (so-called unevenness correction cosmetic) in which minute irregularities on the skin such as fine wrinkles and pores are naturally blurred and made inconspicuous, and a plurality of substantially spherical particles aggregate and coalesce. The present invention relates to a cosmetic for correcting unevenness, characterized by containing a modified composite powder having a shape having a plurality of unevennesses. And, in more detail, the fine irregularities on the skin such as fine wrinkles and pores are naturally blurred, the effect of making them inconspicuous is excellent, the spread is good, and the skin is secreted from the skin over time by sebum etc. The present invention relates to an unevenness-correcting cosmetic which has an excellent effect of preventing a phenomenon of glowing (so-called shiny phenomenon).
[0002]
[Prior art]
In the recent aging society, cosmetics having various unevenness correcting effects have been developed according to the needs of women who want to have young skin forever. Unevenness correction cosmetics are special-purpose cosmetics that make undesired fine irregularities such as fine wrinkles and pores on the skin before and after makeup makeup, and a function that makes undesired fine irregularities less noticeable. Makeup cosmetics such as foundations, concealers, and base materials. Many products have been released and are well received in the market.
[0003]
In these conventional unevenness correcting cosmetics, a method of embedding a transparent composition in which a powder having a specific range of refractive index and a high-viscosity silicone oil are embedded in recesses on the skin to smooth the unevenness. (See, for example, Patent Document 1) and a method of arranging a specific spherical powder together with a film-forming agent on the skin to make the unevenness of the skin difficult to see by light scattering on the surface of the applied film (for example, see Patent Document 2). Etc. were used.

[Problems to be solved by the invention]
However, in a method using a composition in which a powder having a specific range of refractive index and a high-viscosity silicone oil are combined, since the silicone oil serves as a skeleton, there is poor skin familiarity unique to silicone oil. In addition, aggregates of the powder and the high-viscosity silicone oil may be generated at the time of application, and so-called "slipping" may occur. In addition, a method of arranging a specific spherical powder together with a film forming agent on the skin and making it difficult to see the unevenness of the skin by light scattering on the surface of the applied film is a method of mixing the powder unless a considerable amount of the film forming component is blended. It is impossible to arrange them, and in that case, there is a case where a shiny phenomenon occurs in which the skin glows with time.
