Description

本発明は、ソフトフォーカス効果を発揮し、白浮きせず、適度でかつ均一なツヤ感を有し、肌なじみの良好な粉末状化粧料に関する。 The present invention relates to a powdery cosmetic that exhibits a soft focus effect, does not float white, has an appropriate and uniform gloss, and has a good skin fit.

粉末状化粧料である粉おしろいは、タルクなどの粉体を主成分として、主として乳化ファンデーションや油性ファンデーションの上に塗布して、“あぶらびかり”やベタツキを押さえて、マットで透明感のある肌色を演出したり、汗や皮脂を押さえて化粧持ちを良くする目的で使用されている。（非特許文献１） Powdered powder, which is a powdery cosmetic, is mainly made of powder such as talc, and is applied mainly on emulsifying foundations or oily foundations. It is used for the purpose of directing skin color and improving the longevity of skin by suppressing sweat and sebum. (Non-Patent Document 1)

そこで滑らかで均一な伸び、広がりを付与するために、アスペクト比が１５０〜２５０のマイカを用いた粉末状化粧料（特許文献１参照）が開示されている。 Therefore, a powdery cosmetic (see Patent Document 1) using mica having an aspect ratio of 150 to 250 in order to impart smooth and uniform elongation and spread is disclosed.

しかしながら、高アスペクト比の粉体を用いた場合、ツヤがありすぎ、手かった印象の仕上がりになる問題点があった。そこで、本発明においては白浮きせず、適度でかつ均一なツヤ感を有し、肌なじみの良好な使用感を発揮し、しかもソフトフォーカス効果を有する粉末状化粧料を提供することを目的とした。 However, when a powder with a high aspect ratio is used, there is a problem that the glossy finish is too much and the impression is good. Accordingly, an object of the present invention is to provide a powdery cosmetic that does not appear white, has an appropriate and uniform gloss, exhibits a good feeling of familiarity with the skin, and has a soft focus effect. did.

本願発明は、（Ａ）アスペクト比が１００以上でかつ平均粒子径１０〜１００μｍのマイカと、（Ｂ）平均粒子径１〜１５μｍの真珠光沢顔料を含有する、粉末状化粧料を提供する。 The present invention provides a powdery cosmetic comprising (A) mica having an aspect ratio of 100 or more and an average particle diameter of 10 to 100 μm and (B) a pearlescent pigment having an average particle diameter of 1 to 15 μm.

本発明の粉末状化粧料はソフトフォーカス効果を発揮し、白浮きせず、適度でかつ均一なツヤ感を有し、肌なじみの良好な使用感を発揮する。 The powdery cosmetic of the present invention exhibits a soft focus effect, does not float white, has an appropriate and uniform gloss feeling, and exhibits a good feeling of familiarity with the skin.

図１は、実施例１及び比較例１〜３のソフトフォーカス効果を示す図である。FIG. 1 is a diagram illustrating the soft focus effect of Example 1 and Comparative Examples 1-3.

以下本発明を実施するための形態を説明するが、本明細書中で平均粒子径はレーザー回析式粒度分布測定により測定した値で示す。 DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described. In the present specification, the average particle diameter is a value measured by laser diffraction type particle size distribution measurement.

本発明の粉末状化粧料は、（Ａ）アスペクト比が１００以上でかつ平均粒子径１０〜１００μｍのマイカと、（Ｂ）平均粒子径１〜１５μｍの真珠光沢顔料を必須成分として含有する。 The powdery cosmetic of the present invention contains (A) mica having an aspect ratio of 100 or more and an average particle size of 10 to 100 μm, and (B) a pearlescent pigment having an average particle size of 1 to 15 μm as essential components.

（Ａ）のアスペクト比が１００以上でかつ平均粒子径１０〜１００μｍのマイカとしては、化粧料に配合しうるものであれば特に限定されない。市販品の例として、山口雲母工業所社製マイカＦＡ−４５０、同ＮＣＦ−３２２、同ＴＭ−１０、同ＴＭ−２０等が挙げられる。マイカのアスペクト比が１００未満の場合、肌なじみ、きしみ感、ツヤ感、白浮き、ソフトフォーカス効果のいずれの効果も発揮しなくなる場合がある。かかるマイカの配合量は、粉末状化粧料全量に対し１０〜９９質量％が好ましく、さらには２０〜９９質量％がより好ましい。 The mica having an aspect ratio of (A) of 100 or more and an average particle diameter of 10 to 100 μm is not particularly limited as long as it can be blended in cosmetics. Examples of commercially available products include Mica FA-450, NCF-322, TM-10, TM-20, and the like manufactured by Yamaguchi Mica Industry Co., Ltd. When the aspect ratio of mica is less than 100, any of skin familiarity, creaking, gloss, whitening, and soft focus effect may not be exhibited. The amount of mica is preferably 10 to 99% by mass, more preferably 20 to 99% by mass, based on the total amount of the powdery cosmetic.

（Ｂ）の平均粒子径１〜１５μｍの真珠光沢顔料としては、化粧料に配合しうるものであれば特に限定されない。真珠光沢顔料は、真珠光沢を有する通常の雲母チタンの他に、酸化スズ被覆雲母チタン、酸化鉄被覆雲母チタン、酸化鉄被覆雲母、黒酸化鉄被覆雲母チタン、酸化鉄・黒酸化鉄被覆雲母チタン、カルミン被覆雲母チタン、カルミン・コンジョウ被覆雲母チタン、酸化鉄・カルミン処理雲母チタン、コンジョウ処理雲母チタン、酸化鉄・コンジョウ処理雲母チタン、酸化クロム処理雲母チタン、黒酸化チタン処理雲母チタン、アクリル樹脂被覆アルミニウム末（色材を含有してもよい）、酸化チタン被覆マイカ、酸化チタン被覆オキシ塩化ビスマス、酸化チタン被覆タルク、着色酸化チタン被覆マイカ、オキシ塩化ビスマス、魚鱗箔等を使用することができる。市販品の例として、ＦｌａｍｅｎｃｏＳａｔｉｎＰｅａｒｌ（ＢＡＳＦ社製）、ＴｉｍｉｒｏｎＳｕｐｅｒＳｉｌｋ（Ｍｅｒｃｋ社製）、ＰＲＥＳＴＩＧＥＳｉｌｖｅｒＰｉｇｍｅｎｔｓｓｏｆｔｓｉｌｖｅｒ（ＥＣＫＡＲＴ社製）などが挙げられる。真珠光沢顔料の平均粒子径が１５μｍを超えると、ソフトフォーカス効果が得られなくなる。かかる真珠光沢顔料の配合量は、粉末状化粧料全量に対し、０．１〜５質量％が好ましい。５質量％を超えて配合すると、白浮きや、過剰なツヤの原因となる場合がある The pearlescent pigment having an average particle diameter of 1 to 15 μm of (B) is not particularly limited as long as it can be blended in cosmetics. The pearl luster pigments are not only normal mica titanium with pearl luster but also tin oxide coated mica titanium, iron oxide coated mica titanium, iron oxide coated mica, black iron oxide coated mica titanium, iron oxide / black iron oxide coated mica titanium , Carmine-coated mica titanium, Carmine-konjo-coated mica titanium, Iron oxide-carmine-treated mica titanium, Conger-treated mica titanium, Iron-oxide-konjo-treated mica titanium, Chromium oxide-treated mica titanium, Black-titanium oxide-treated mica titanium, Acrylic resin coating Aluminum powder (which may contain a coloring material), titanium oxide-coated mica, titanium oxide-coated bismuth oxychloride, titanium oxide-coated talc, colored titanium oxide-coated mica, bismuth oxychloride, fish scale foil, and the like can be used. Examples of commercially available products include Flamenco Satin Pearl (manufactured by BASF), Timron Super Silk (manufactured by Merck), PRESTIGE Silver Pigments soft silver (manufactured by ECKART), and the like. When the average particle size of the pearlescent pigment exceeds 15 μm, the soft focus effect cannot be obtained. The blending amount of the pearl luster pigment is preferably 0.1 to 5% by mass with respect to the total amount of the powdery cosmetic. If it exceeds 5% by mass, it may cause whitening or excessive gloss.

また、これら成分（Ａ）、（Ｂ）の粉体は、前記感触を損ねない範囲で、例えば、フッ素化合物、シリコーン系油剤、金属石ケン、ロウ、界面活性剤、油脂、炭化水素等による処理等、通常公知の方法で表面処理されているものを用いても良い。 Further, the powders of these components (A) and (B) may be treated with, for example, a fluorine compound, a silicone-based oil agent, a metal soap, a wax, a surfactant, an oil or fat, a hydrocarbon, etc., as long as the touch is not impaired. For example, a material that has been surface-treated by a generally known method may be used.

本発明の粉末状化粧料には、上記必須成分のほかに、通常化粧料に用いられる成分として、例えば成分（Ａ）、（Ｂ）以外の粉体、油剤、界面活性剤、紫外線吸収剤、保湿剤、防腐剤、抗菌剤、香料、抗炎症剤、酸化防止剤、金属封鎖剤、着色剤、美容剤、制汗剤等を本発明の効果を損なわない範囲で含有することができる。 In addition to the above essential components, the powdery cosmetics of the present invention include, as components usually used in cosmetics, for example, powders other than the components (A) and (B), oils, surfactants, ultraviolet absorbers, Moisturizers, antiseptics, antibacterial agents, fragrances, anti-inflammatory agents, antioxidants, metal sequestering agents, coloring agents, beauty agents, antiperspirants, and the like can be contained within a range not impairing the effects of the present invention.

ソフトフォーカス効果の測定
表１に示した実施例１及び比較例１〜３を用いてソフトフォーカス効果の測定を行った。測定は変角測色計（日本電色工業株式会社製、工学部ＧＣ，計測部シグマ９０）を用い、投光角４５°、受光角−７０°〜７０°の条件で測定した。 Measurement of soft focus effect The soft focus effect was measured using Example 1 and Comparative Examples 1 to 3 shown in Table 1. The measurement was performed using a variable angle colorimeter (manufactured by Nippon Denshoku Industries Co., Ltd., Engineering Department GC, Measurement Department Sigma 90) under conditions of a light projection angle of 45 ° and a light reception angle of −70 ° to 70 °.

図１に示した通り、本発明の実施例１は、比較例より−４０°〜２０°の反射強度が高く、３５°〜６０°にある正反射光が低く、高いソフトフォーカス効果を示していた。 As shown in FIG. 1, Example 1 of the present invention has a higher reflection intensity of −40 ° to 20 ° than that of the comparative example, lower specular reflection light at 35 ° to 60 °, and shows a high soft focus effect. It was.

表１に示したとおり使用感的には、実施例１は、肌なじみきしみ感が良好で、適度なツヤ感を有し、白浮きしないという良好な使用感であった。これに対し、アスペクト比の低いマイカを配合した比較例１，２においては全ての評価項目において良好な結果が得られなかった。また平均粒子径の大きい真珠光沢顔料を配合した比較例３は、ツヤ感がありすぎ、ソフトフォーカス効果も認められなかった。 As shown in Table 1, in terms of usability, Example 1 had a good feeling of familiarity with skin, a good gloss, and a good feeling of whitening. On the other hand, in Comparative Examples 1 and 2 containing mica having a low aspect ratio, good results were not obtained for all evaluation items. Further, Comparative Example 3 in which a pearlescent pigment having a large average particle size was blended was too glossy and no soft focus effect was observed.
