Description

【0001】
【発明の属する技術分野】
本発明は、結晶セルロースとフッ素化合物にて複合処理した処理顔料及び該顔料を配合したメイクアップ化粧料に関する。さらに詳しくは、肌への伸展性、付着性に優れる結晶セルロースと撥水撥油性に優れるフッ素化合物とを組み合わせ用いることで、フッ素化合物の欠点である肌に対する親和性の低さを改善し、肌等に対する付着性を高め、感触、化粧持ち効果に優れることを特徴とする処理顔料及びメイクアップ化粧料に関する。
【0002】
【従来の技術】
従来、粉体類をフッ素化合物にて処理することは、特開昭61−55481号公報、特開昭62−249913号公報、特開昭63−107911号公報、米国特許第3632744号公報等にて広く知られている。一方で、親水性高分子類の一つである結晶セルロースは、クリーム状の水分散液として基礎化粧品、頭髪化粧品に、また白色微粉末の粉体としても無機顔料と併用され、メイクアップ化粧品に非常に幅広くも用いられる(特開昭61−189210号公報、特開昭54−62328号公報参照)。
【0003】
【発明が解決しようとする課題】
フッ素化合物処理顔料は撥水撥油性に富み、化粧の持続性を向上させる効果があるため、夏用のメイクアップ化粧料を中心に多用されている。従来、フッ素化合物で処理した粉体をメイクアップ化粧料に配合する場合、バインダーとして高い粘性の油剤を用いる必要があった。これは、フッ素化合物処理粉体の表面が撥水撥油性である場合が多く、低い粘性の油剤でははじかれてしまうため、フッ素化合物処理粉体をつなぎとめるバインダーとしての役割が弱くなってしまい、その結果、肌への付着性、肌なじみが悪くなり、粉っぽい使用感となってしまうためである。
【0004】
一方、高い粘性の油剤を配合する場合、確かにフッ素化合物処理顔料をつなぎとめることが可能となるが、粘性が高いためにメイクアップ化粧料に配合しにくい問題が生じてしまう。例えばパウダーファンデーションの製造の例にとれば、ヘンシェルミキサー等攪拌力の弱い装置を用いてバインダーの混合を行う場合には、バインダーが均一に混合されず局在化する傾向がみられた。また、得られる化粧料は感触面においても伸びが重くなったり、その仕上がりもムラになったりする傾向がみられた。
【0005】
メイクアップ化粧料に用いられる顔料に、結晶セルロースとフッ素化合物の組み合わせによる処理を施すことについてはこれまで知られていなかった。通常、結晶セルロースのような親水性高分子で顔料で処理する場合は、処理量が多くなると得られる処理顔料の凝集強度が強くなる傾向があり、メイクアップ化粧品に配合した場合に凝集体の硬さに起因して感触が悪くなる欠点があった。すなわち、本発明の目的は、撥水撥油性に優れるフッ素化合物の特性を損なうことなく、フッ素化合物の欠点である肌に対する親和性の低さを改善し、肌等に対する付着性を高め、感触、化粧持ち効果、肌への伸展性に優れるメイクアップ化粧料を提供するにある。
【0006】
【課題を解決するための手段】
本発明者等は、これらの問題に鑑み、結晶セルロースの処理粉体の凝集強度を適度に制御する技術、滑らかな感触を付与する技術を、フッ素化合物やフッ素処理顔料との組合せについて検討を行ったところ、フッ素化合物と共に結晶セルロースを用いて処理を行うことでフッ素化合物処理顔料の化粧持続性等の優れた特徴を阻害することなく、肌に対する付着性に優れた官能特性を有し、適度な伸び、すべり性を与え、フッ素系素材の肌なじみの改善を行うことに成功した。そしてこれを配合したメイクアップ化粧料が塗布時の均一感と感触に優れ、かつ化粧持続性を有することを見出し、本発明を完成した。すなわち、本発明は、結晶セルロースとフッ素化合物とで複合処理した顔料、及び該顔料を配合することを特徴とするメイクアップ化粧料にある。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a treated pigment complex-treated with crystalline cellulose and a fluorine compound, and a makeup cosmetic containing the pigment. More specifically, by using a combination of crystalline cellulose having excellent extensibility to the skin and excellent adhesion, and a fluorine compound having excellent water and oil repellency, the low affinity for the skin, which is a drawback of the fluorine compound, is improved. The present invention relates to a treated pigment and a makeup cosmetic, which are characterized in that they have high adhesiveness to the composition and the like, and have an excellent touch and a cosmetic holding effect.
[0002]
[Prior art]
Conventionally, treating powders with a fluorine compound is disclosed in JP-A-61-55481, JP-A-62-249913, JP-A-63-107911, U.S. Pat. No. 3,632,744 and the like. And widely known. On the other hand, crystalline cellulose, one of the hydrophilic polymers, is used as a creamy aqueous dispersion in basic cosmetics and hair cosmetics, and as a fine white powder in combination with inorganic pigments, making it into makeup cosmetics. It is also used very widely (see JP-A-61-189210 and JP-A-54-62328).
[0003]
[Problems to be solved by the invention]
Fluorine compound-treated pigments are rich in water / oil repellency and have the effect of improving the durability of makeup, and therefore are frequently used mainly in summer makeup cosmetics. Conventionally, when a powder treated with a fluorine compound is blended into a makeup cosmetic, it has been necessary to use a highly viscous oil as a binder. This is because the surface of the fluorine compound-treated powder is often water- and oil-repellent, and is repelled by a low-viscosity oil agent, which weakens the role as a binder for binding the fluorine compound-treated powder. As a result, the adhesion to the skin and the adaptation to the skin are deteriorated, and the feeling of use becomes powdery.
[0004]
On the other hand, when a highly viscous oil agent is blended, the fluorine compound-treated pigment can certainly be retained, but a problem arises in that it is difficult to blend it into a makeup cosmetic because of its high viscosity. For example, in the case of producing a powder foundation, when a binder is mixed using an apparatus having a low stirring power such as a Henschel mixer, the binder tends to be localized without being uniformly mixed. In addition, the obtained cosmetics tended to have a large elongation on the touch surface and a tendency that the finish was uneven.
[0005]
It has not been known to treat pigments used in makeup cosmetics with a combination of crystalline cellulose and a fluorine compound. In general, when a pigment is treated with a hydrophilic polymer such as crystalline cellulose, a large amount of the treated pigment tends to increase the cohesive strength of the obtained pigment. However, there was a drawback that the feel was deteriorated due to this. That is, the object of the present invention is to improve the low affinity for the skin, which is a disadvantage of the fluorine compound, to enhance the adhesion to the skin and the like, without impairing the properties of the fluorine compound having excellent water and oil repellency, An object of the present invention is to provide a makeup cosmetic which has a long-lasting makeup effect and extensibility on the skin.
[0006]
[Means for Solving the Problems]
In view of these problems, the present inventors have studied a technique for appropriately controlling the cohesive strength of a treated powder of crystalline cellulose and a technique for imparting a smooth feel, in combination with a fluorine compound or a fluorine-treated pigment. However, by performing the treatment using crystalline cellulose together with a fluorine compound, without impairing the excellent features such as cosmetic persistence of the fluorine compound-treated pigment, having a functional property with excellent adhesion to the skin, moderate It gives elongation and smoothness, and succeeds in improving skin familiarity with fluorine-based materials. The present inventors have found that a makeup cosmetic containing this compound has excellent uniformity and feel during application and has long-lasting makeup, and has completed the present invention. That is, the present invention resides in a pigment which has been subjected to a composite treatment with crystalline cellulose and a fluorine compound, and a makeup cosmetic comprising the pigment.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
The crystalline cellulose used in the present invention is obtained by hydrolyzing wood pulp or linter pulp using an inorganic acid, removing amorphous substances and impurities, neutralizing and washing, and is insoluble in water, ethanol and ether. belongs to. The shape is not particularly limited, and it can be used in the form of a powder, an aqueous dispersion or the like.
