Description
本発明は、構成成分として（Ａ）薄片状基質表面上に酸化チタンを主成分とする金属酸化物被覆層が形成されて成るパール顔料の表面を、粒子径２００〜４００ｎｍの球状有機粉体で２．０〜１０．０重量％被覆した複合粉体、（Ｂ）絹雲母の表面を、ルチル型微粒子酸化チタンで１５．０〜２５．０重量％被覆した複合粉体、及び（Ｃ）２５℃においてペースト状である油性成分を含有する、顔に立体感を与え、たるみを隠しリフトアップした印象を与える効果と紫外線防御効果を両立しながら、さらに化粧もちに優れる固形粉末化粧料に関する。 In the present invention, the surface of a pearl pigment formed by forming a metal oxide coating layer mainly composed of titanium oxide on the surface of a flaky substrate as a constituent component is a spherical organic powder having a particle diameter of 200 to 400 nm. Composite powder coated with 2.0 to 10.0% by weight, (B) Composite powder coated with 15.0 to 25.0% by weight of rutile type fine titanium oxide on the surface of sericite, and (C) 25 The present invention relates to a solid powder cosmetic containing an oily component in a paste form at 0 ° C., providing a three-dimensional effect on the face, concealing sagging and giving a lift-up impression, and an ultraviolet protection effect, and further improving makeup.
従来、メイクアップ化粧料には、肌のシミ、ソバカス、色ムラ、くすみ、毛穴の目立ち、シワ等を隠し、肌を綺麗に見せたり、質感を変えたりする機能がある。しかし、高齢化社会を迎え、これらの機能に加えて、加齢に伴う顔や肌のたるみを隠して若々しい印象の顔に見せる機能もこれからの時代は重要になってくると考えられる。 Conventionally, makeup cosmetics have functions to hide skin spots, freckles, color unevenness, dullness, conspicuous pores, wrinkles, etc., to make the skin look beautiful and to change the texture. However, as we enter an aging society, in addition to these functions, the function of hiding the sag of the face and skin that accompanies aging and making it appear as a youthful face will be important in the coming years.
このうち、たるみを隠して若々しい印象を与えるためには、顔に立体感を与えることが重要である。そのために、顔を上下に分け、上部と下部で色調の異なるファンデーションを用いて、上部のメイクアップ化粧料の明度が下部のものよりも高くなるように塗布して陰影をつけ、フェイスラインをすっきり見せる方法（特許文献１）、低次酸化チタンで着色された干渉色を有さない雲母チタン系顔料を配合した下地化粧料を塗布してからファンデーションを重ねることで、フェイスラインや鼻筋をすっきり見せ立体感を上げる方法（特許文献２）、微細なパール顔料と球状樹脂粉末を最適な量と最適な混合比でファンデーションや化粧下地へ配合する方法（特許文献３）等が示されている。 Among these, it is important to give the face a three-dimensional effect in order to hide the slack and give a youthful impression. For that purpose, the face is divided into upper and lower parts, using a foundation with different color tones at the top and bottom, and applied so that the brightness of the makeup cosmetics on the top is higher than the one on the bottom, shading, and the face line is clean How to show (Patent Document 1), by applying a foundation cosmetic blended with a mica titanium pigment that does not have interference color colored with low-order titanium oxide, and then the foundation is overlaid, the face line and nose are clearly shown A method of increasing the three-dimensional effect (Patent Document 2), a method of blending a fine pearl pigment and a spherical resin powder into a foundation or a makeup base with an optimal amount and an optimal mixing ratio (Patent Document 3), and the like are shown.
しかし、特許文献１のような顔の場所によって塗り分ける方法では、化粧塗膜の微妙な境目が気になり、自然な仕上がりとは言い難く、また、特許文献２の方法では、メイクアップ化粧品を組み合わせて使用しているためメイクのテクニックが必要となり、簡便にリフトアップした印象に仕上げるのは難しい。さらに、特許文献３のような方法では、パール顔料の光の正反射と球状樹脂粉末の光の拡散反射が、互いの光の特性を相殺して、十分に若々しい印象を与えるものではなかった。 However, in the method of painting differently depending on the location of the face as in Patent Document 1, the delicate boundary of the cosmetic coating is concerned, and it is difficult to say that the finish is natural, and in the method of Patent Document 2, makeup cosmetics are not used. Because they are used in combination, make-up techniques are required, and it is difficult to create a lifted impression. Furthermore, in the method as disclosed in Patent Document 3, the regular reflection of the light of the pearl pigment and the diffuse reflection of the light of the spherical resin powder cancel each other's light characteristics and do not give a sufficiently youthful impression. It was.
さらに、小鼻から口元あたりの頬の下部において、顔のたるみによって影が発現し、この影がたるみを認識させているとして、この影を消して若返ったように見せるレフ板のような効果を持った複合粉末も特許文献４に紹介されている。 In addition, a shadow appears due to sagging of the face from the nose to the lower part of the cheek around the mouth, and if this shadow recognizes sagging, it has the effect of a reflex board that makes this shadow disappear and looks rejuvenated A composite powder is also introduced in Patent Document 4.
しかしながら、この複合粉末の利用では、複合化によって母体の雲母チタンの明るさが大きく低下し、また、実際に顔の影が少なくなっているものの、逆に、顔が膨張しているように見え太った印象を与えてしまっていた。 However, with the use of this composite powder, the brightness of the parent mica titanium is greatly reduced due to the composite, and the face shadow actually decreases, but on the contrary, the face appears to expand. It gave a fat impression.
また、肌のシワや毛穴の目立ち等については、特許文献５のようにアクリル樹脂の球状微細粒子を薄片状パール顔料に４０〜６０重量％の濃度で被覆した複合粉体により、パール顔料のつやを抑えて、均一な乱反射の強度をコントロールすることが行われているが、肌の自然さや透明感はあるものの、やはり、顔から反射してくる光が広がるために顔がぼやけた印象で太ったように見える傾向があり、肌のたるみを逆に強調してしまっていた。 Further, as to wrinkles on the skin and conspicuous pores, the pearl pigment is polished with a composite powder in which spherical fine particles of acrylic resin are coated at a concentration of 40 to 60% by weight as in Patent Document 5. Although the intensity of uniform diffuse reflection is controlled by suppressing the natural light, the skin is natural and transparent, but the light reflected from the face is still widened and the face is blurred. It tends to look like it and emphasizes the sagging of the skin.
一方、メイクアップ化粧料の重要な機能の一つに、紫外線から肌を守る機能がある。このため、従来から紫外線防御効果を化粧料に持たせるために、様々な酸化チタン、酸化亜鉛をはじめとする無機系紫外線防御剤が汎用されている（非特許文献１〜３）。これらの技術の進歩は、紫外線の皮膚の老化に及ぼす影響や皮膚がんとの因果関係などから紫外線の有害性が明らかになってきた中で、一般消費者における紫外線防御への関心が高まり、より高い紫外線防御効果を有する化粧料の開発が必要となってきたことに起因する。 On the other hand, one of the important functions of makeup cosmetics is to protect the skin from ultraviolet rays. For this reason, in order to give the cosmetics an ultraviolet protection effect, inorganic UV protection agents including various titanium oxides and zinc oxides have been widely used (Non-Patent Documents 1 to 3). The advancement of these technologies has revealed the harmful effects of ultraviolet rays from the effects of ultraviolet rays on skin aging and the causal relationship with skin cancer. This is because the development of cosmetics having a higher UV protection effect has become necessary.
しかしながら、紫外線のカット効果を高めるために、無機系紫外線防御剤を増量すると、使用感や肌の仕上がりの面で弊害が出てくる。 However, if the amount of the inorganic ultraviolet protective agent is increased in order to enhance the effect of cutting off ultraviolet rays, adverse effects appear in terms of the feeling of use and the finish of the skin.
例えば、紫外線防御効果を有する微粒子酸化チタンは分散性が悪く、凝集しやすいため、のびが悪く、高い紫外線防御効果を求めて高配合すると、塗布時ののびの滑らかさを失うという問題点があった。さらには、皮膚の上では均一に塗布されないため、隙間が空いてしまい、微粒子酸化チタンの配合量に見合った紫外線防御効果を得られないという欠点や、光を遮り肌の透明感やつやを損ねてしまうため、立体感のない(のっぺりとした)顔印象になるといった仕上がりの不自然さが目立ってくる。すなわち、肌に立体感を与えるために様々な工夫をこらしても、微粒子酸化チタンを配合することで、その効果を大きく損ねてしまうという問題があった。 For example, fine particle titanium oxide having an ultraviolet protection effect is poor in dispersibility and easily agglomerated, so that it has a problem of spreading, and if high blending is required for a high ultraviolet protection effect, the smoothness of spreading at the time of application is lost. It was. Furthermore, since it is not evenly applied on the skin, gaps are left, and the UV protection effect corresponding to the amount of particulate titanium oxide cannot be obtained, and the transparency and glossiness of the skin is impaired by blocking light. As a result, unnatural finishes such as a three-dimensional (non-shrinking) face impression become conspicuous. That is, even if various ideas are applied to give the skin a three-dimensional effect, there is a problem that the effect is greatly impaired by adding fine particle titanium oxide.
こうした理由から、肌に立体感を与え、若々しい印象の顔を演出することと、紫外線防御効果を両立させることは非常に困難であった。 For these reasons, it has been very difficult to impart a three-dimensional effect to the skin and produce a youthful face with a UV protection effect.
以上の状況を踏まえ、特に、加齢に伴う顔や肌のたるみ等が気になる年代の女性をターゲットとしたメイクアップ化粧料では、つやのある若々しい印象の顔に見せる機能を有しながら、そのつや感を損なうことなく紫外線防御効果に優れたメイクアップ化粧料の開発が望まれていた。 Based on the above situation, makeup cosmetics targeted at women who are particularly concerned about facial aging and skin sagging, etc., while having the function of showing a glossy, youthful face Therefore, there has been a demand for the development of a makeup cosmetic that has an excellent UV protection effect without impairing its gloss.
従って、本発明の目的は、顔に立体感を与え、たるみを隠しリフトアップした印象を与えて、若々しく見せるメイクアップ効果を有しながら、さらに紫外線防御効果に優れる、すなわち、つや感を損なわずに紫外線から肌を守る機能を持つ固形粉末化粧料を提供することにある。 Therefore, the object of the present invention is to provide a three-dimensional effect on the face, hide the sagging and give a lifted-up impression, have a makeup effect that makes youthful, and have an excellent UV protection effect, that is, a glossy feeling. The object is to provide a solid powder cosmetic having a function of protecting the skin from ultraviolet rays without damage.
本発明者は、このような事情に鑑み、鋭意研究を重ねた結果、構成成分として（Ａ）薄片状基質表面上に酸化チタンを含有する金属酸化物被覆層が形成されて成るパール顔料の表面を、粒子径２００〜４００ｎｍの球状有機粉体で２．０〜１０．０重量％（パール顔料と球状有機粉体の全重量に対する球状有機粉体の重量百分率）被覆した複合粉体、（Ｂ）絹雲母の表面を、ルチル型微粒子酸化チタンで１５．０〜２５．０重量％（絹雲母とルチル型微粒子酸化チタンの全重量に対するルチル型微粒子酸化チタンの重量百分率）被覆した複合粉体、及び（Ｃ）２５℃でペースト状の油性成分を含有する固形粉末化粧料であれば、それを塗布することによって、今まで以上に顔がリフトアップしたように見えて若々しい印象を与えながらも、紫外線防御効果、化粧もちに優れることを見出し、本発明を完成した。 In view of such circumstances, the present inventor has conducted extensive research and as a result, (A) a surface of a pearl pigment formed by forming a metal oxide coating layer containing titanium oxide on a flaky substrate surface as a constituent component A composite powder in which 2.0 to 10.0 wt% (weight percentage of the spherical organic powder with respect to the total weight of the pearl pigment and the spherical organic powder) is coated with a spherical organic powder having a particle diameter of 200 to 400 nm, (B ) A composite powder in which the surface of sericite is coated with 15.0 to 25.0% by weight of rutile type fine particle titanium oxide (weight percentage of rutile type fine particle titanium oxide based on the total weight of sericite and rutile type fine particle titanium oxide), And (C) If it is a solid powder cosmetic containing a paste-like oily component at 25 ° C., applying it will give the youthful impression that the face appears to be lifted up more than before Even purple Found that excellent line defense effect, the cosmetic have, and have completed the present invention.
すなわち、パール顔料を球状有機粉体で被覆した複合粉体の反射特性である、立体感を生み出す反射光の明るさや高い角度依存性を、絹雲母をルチル型微粒子酸化チタンで被覆した紫外線防御複合粉体が弱めることなく、紫外線防御効果を発揮する。さらには、これらの他に２５℃でペースト状の油性成分を含む固形粉末化粧料は、塗布時のフィット感に優れ肌のつや感を損なわず立体感の演出と持続に優れることを見出した。 In other words, the reflection characteristics of composite powders in which pearl pigments are coated with spherical organic powders, such as the brightness and high angle dependence of the reflected light that creates a three-dimensional effect, are UV-protective composites in which sericite is coated with rutile fine-particle titanium oxide. Exhibits UV protection without weakening the powder. Furthermore, it has been found that a solid powder cosmetic containing a paste-like oily component at 25 ° C. in addition to these is excellent in fit at the time of application and excellent in rendering and sustaining a three-dimensional effect without impairing the gloss of the skin.
以下、本発明を詳細に説明する。 Hereinafter, the present invention will be described in detail.
本発明の構成成分（Ａ）の複合粉体において、薄片状基質表面上に酸化チタンを主成分とする金属酸化物被覆層が形成されて成るパール顔料とは、粒子径が１〜１５０μｍ（レーザー回折散乱法による累積粒度分布の微粒側から累積１０％と累積９０％に相当するＤ１０とＤ９０の数値幅、又は市販品のカタログ値）、厚みが５μｍ以下で好ましくは１μｍ以下のマイカ、合成マイカ、ガラスフレーク等の薄片状基質表面に、ルチル型やアナターゼ型等の結晶型を有する酸化チタンが均一に被覆された、真珠光沢を有する顔料である。また、被覆する酸化チタン層の厚みを変えて干渉色を与えるものや、酸化チタンの一部を酸化鉄に換えて被覆したもの、無水ケイ酸等をさらに重ねて被覆したものも、本発明でのパール顔料である。 In the composite powder of component (A) of the present invention, the pearl pigment in which a metal oxide coating layer mainly composed of titanium oxide is formed on the surface of a flaky substrate has a particle diameter of 1 to 150 μm (laser Mica or synthetic mica having a thickness of 5 μm or less, preferably 1 μm or less, and a value range of D10 and D90 corresponding to cumulative 10% and cumulative 90% from the fine particle side of the cumulative particle size distribution by diffraction scattering method, or a catalog value of commercial products) A pigment having a pearly luster, in which the surface of a flaky substrate such as glass flakes is uniformly coated with titanium oxide having a crystal type such as a rutile type or anatase type. In addition, the present invention includes those that give interference color by changing the thickness of the titanium oxide layer to be coated, those that are coated with a part of titanium oxide replaced with iron oxide, and those that are further coated with silicic anhydride. Pearl pigment.
このパール顔料は強い光沢を発する粉体であり、顔を明るく見せる効果を有するが、粒子径の大きなパール顔料では、肌の上で疎らに光り、肌が不均一で粗く見えてしまう。それ故、均一な塗膜で肌のキメが整っているように明るく見せるには、粒子の細かなパール顔料が、本発明の被覆される母粉体として好ましく、パール顔料の粒子径が６０μｍ以下のもの（Ｄ９０又は市販品のカタログ値で示される最大値が、６０μｍ以下のもの）が中でも良い。 This pearl pigment is a powder that emits strong luster and has an effect of making the face look brighter. However, a pearl pigment having a large particle diameter shines loosely on the skin, and the skin looks uneven and rough. Therefore, in order to make the skin look bright with a uniform coating film, a fine pearl pigment with a fine particle is preferable as the mother powder to be coated of the present invention, and the particle diameter of the pearl pigment is 60 μm or less. (The maximum value indicated by the catalog value of D90 or a commercial product is 60 μm or less).

本願発明は、絹雲母をルチル型微粒子酸化チタンで被覆した複合粉体とペースト状油性成分を組み合わせて、パール顔料を球状有機粉体で被覆した複合粉体の光学的特性と紫外線防御効果を両立させた固形粉末化粧料である。 The present invention combines the optical properties and UV protection effect of a composite powder in which a pearl pigment is coated with a spherical organic powder by combining a composite powder in which sericite is coated with rutile fine-particle titanium oxide and a pasty oily component. Solid powder cosmetic.
本発明の構成成分（Ｂ）の複合粉体において、母粒子となる絹雲母とは、天然に産出する微結晶含水ケイ酸アルミニウムカリウムであり、一般にはセリサイトと呼ばれるマイカの一種である。他のマイカに比べて、粉体に厚みがあり、皮膚に塗布する時よくのび、滑らかな使用感で絹糸様の光沢がある。合成マイカと比べても天然の絹雲母は、柔らかい感触で透明性も高い。本発明では、このような観点から天然の絹雲母を利用するが、特に透明性を重視して、ハンター方式による白色度（ＪＩＳ Ｚ ８７２２）が８８．０以上のものがより好ましい。さらには、一層の滑らかさやくすみの無さから、愛知県北設楽郡東栄町で産出される振草産絹雲母が好ましく、ハンター方式による白色度が９０．０以上のものが最も好ましい。市販品としてはセリサイト ＦＳＥ、Ｆ１００、Ｆ８８、Ｆｉｎｅ Ｍｉｃａ（いずれも三信鉱工株式会社製）等がある。 In the composite powder of the component (B) of the present invention, the sericite as the mother particle is a microcrystalline hydrous aluminum potassium silicate produced naturally, and is a kind of mica generally called sericite. Compared to other mica, the powder has a thicker thickness, it spreads well when applied to the skin, and has a silky luster with a smooth feel. Compared to synthetic mica, natural sericite has a soft feel and high transparency. In the present invention, natural sericite is used from such a point of view, and in particular, with emphasis on transparency, a hunter-type whiteness (JIS Z 8722) of 88.0 or more is more preferable. Further, from the viewpoint of further smoothness and lack of dullness, preferred is shinseki sericite produced in Toei-cho, Kitashiraku-gun, Aichi Prefecture, and most preferably has a hunter whiteness of 90.0 or more. Commercially available products include Sericite FSE, F100, F88, Fine Mica (all manufactured by Sanshin Mining Co., Ltd.), and the like.
本発明の構成成分（Ｂ）の複合粉体に用いる絹雲母の平均粒子径（レーザー回折散乱法による）は、分級により１５μｍ以下のものが好ましい。より好ましくは、７〜１２μｍであり、さらに好ましくは約１０μｍである。このとき、より高い滑らかさが得られる。 The average particle diameter (by laser diffraction scattering method) of sericite used for the composite powder of component (B) of the present invention is preferably 15 μm or less by classification. More preferably, it is 7-12 micrometers, More preferably, it is about 10 micrometers. At this time, higher smoothness is obtained.
本発明の構成成分（Ｂ）の複合粉体において、絹雲母表面に複合化する子粒子は、ルチル型の微粒子酸化チタンである。ルチル型微粒子酸化チタンは、アナターゼ型微粒子酸化チタンよりも光安定性に優れ、化粧料に配合した場合に他の原料に及ぼす影響が少なく、さらに高い紫外線遮断能と透明性を有する。 In the composite powder of the component (B) of the present invention, the child particles to be combined on the sericite surface are rutile type fine particle titanium oxide. Rutile type fine particle titanium oxide is superior in light stability to anatase type fine particle titanium oxide, has little influence on other raw materials when blended in cosmetics, and has higher ultraviolet blocking ability and transparency.
本発明の構成成分（Ｂ）の複合粉体に用いるルチル型微粒子酸化チタンの一次粒子径は、高い紫外線遮断能と可視光の透過性を考慮して、１０〜５０ｎｍ（電子顕微鏡下にて実測した長径の平均値）のものが好ましい。 The primary particle size of rutile type fine particle titanium oxide used for the composite powder of the constituent component (B) of the present invention is 10 to 50 nm (measured under an electron microscope in consideration of high ultraviolet blocking ability and visible light transmittance). The average value of the major axis) is preferred.
本発明では、上記のように優れた特性を有する絹雲母とルチル型微粒子酸化チタンを複合化することにより、高い紫外線遮断能を有しながら、肌の透明感やつやを損なわせない複合粉体を調製することを目的とした。この高い紫外線遮断能を持ちながら、肌の透明感やつやを損なわせない複合粉体とは、外部からの紫外線は遮断し、可視光領域の光である肌内部からの反射光や化粧料中に配合された他の粉体による反射光は透過させる粉体である。
このような粉体を実現するために、本発明ではルチル型微粒子酸化チタンを、予め透明性の高い板状の絹雲母表面に均一に点在化させた。
In the present invention, a composite powder that has high UV blocking ability and does not impair the transparency and gloss of the skin by combining sericite and rutile type fine particle titanium oxide having excellent characteristics as described above. Was intended to be prepared. This composite powder that has high UV blocking ability and does not impair the skin's transparency and gloss is to block UV rays from the outside and reflect light from the inside of the skin, which is light in the visible light range, and in cosmetics. The reflected light from the other powders blended in is a powder that transmits.
In order to realize such a powder, in the present invention, rutile type fine particle titanium oxide is uniformly scattered on a highly transparent plate-like sericite surface in advance.
絹雲母上で均一に点在化されるルチル型微粒子酸化チタンの間隔が適当な場合、外部からの紫外線は遮断しながら、肌内部からの反射光や化粧料中に配合された他の粉体による反射光は透過させることができる。一方、ルチル型微粒子酸化チタンが均一に点在化されていても、子粒子の間隔が広すぎる場合は紫外線を十分に遮断することができず、逆に、子粒子の間隔が狭すぎる場合は肌内部からの反射光や化粧料中に配合された他の粉体による反射光を遮ってしまう。
また、ルチル型微粒子酸化チタンが単独で互いに凝集したり、絹雲母上で局在化している場合は、当然ながら十分な紫外線遮断能は望めない。
すなわち、高い紫外線遮断能と良好な可視光透過性を示す複合粉体を調製するには、絹雲母上のルチル型微粒子酸化チタンを均一に点在化させ、さらに子粒子間の間隔を適度に調整することが必要となる。
When the interval of rutile type fine titanium dioxide uniformly scattered on sericite is appropriate, while blocking ultraviolet rays from the outside, reflected light from the inside of the skin and other powders blended in cosmetics The reflected light can be transmitted. On the other hand, even if the rutile-type fine particle titanium oxide is uniformly scattered, if the distance between the child particles is too wide, the ultraviolet rays cannot be sufficiently blocked, and conversely, if the distance between the child particles is too narrow It blocks light reflected from the skin and light reflected by other powders blended in the cosmetic.
In addition, when the rutile type fine particle titanium oxide is agglomerated with each other alone or localized on the sericite, a sufficient ultraviolet blocking ability cannot be expected.
That is, in order to prepare a composite powder exhibiting high UV blocking ability and good visible light transmission, the rutile fine-particle titanium oxide on the sericite is uniformly scattered, and the spacing between the child particles is adjusted appropriately. It is necessary to do.
