Description

本発明は、固形粉体化粧料に関する。 The present invention relates to solid powder cosmetics.

従来、化粧料に毛穴ぼかし効果、素肌感・透明感だけでなく塗布時の感触やすべり性を向上させる目的で、架橋シリコーン粉体(特許文献1参照)、ナイロン粉体(特許文献2参照)、アクリル粉体(特許文献3参照)、ポリ乳酸粉体(特許文献4参照)などの球状ポリマー粉体を配合することが知られている。 Conventionally, cross-linked silicone powder (see Patent Document 1) and nylon powder (see Patent Document 2) have been used for the purpose of improving not only the pore-blurring effect, bare skin feeling and transparency, but also the feel and slipperiness at the time of application. , Acrylic powder (see Patent Document 3), polylactic acid powder (see Patent Document 4) and other spherical polymer powders are known to be blended.

また、紫外線防御効果を有する粉体化粧料は、酸化チタンや酸化亜鉛、酸化セリウムなどの金属酸化物と、UVA、UVB遮断効果のある紫外線吸収剤を主な成分として含有している。しかし、紫外線防御効果を高めるために、紫外線吸収剤を多量に配合した場合、粉体同士の凝集性を高め、化粧膜の均一性や滑らかな伸び広がりといった感触などの基本品質を損なうことがある。一方、金属酸化物に関しては、紫外線防御効果を高める上で好適な粒子径や形状の金属酸化物の開発(特許文献5参照)や、それら粉体の分散性、感触を向上させる表面処理技術(特許文献6参照)が開発されている。 Further, the powder cosmetic having an ultraviolet protection effect contains metal oxides such as titanium oxide, zinc oxide and cerium oxide as main components and an ultraviolet absorber having an ultravioletA and UVB blocking effect. However, when a large amount of UV absorber is added in order to enhance the UV protection effect, the cohesiveness of the powders is increased, and the basic quality such as the uniformity of the cosmetic film and the smooth spread and spread may be impaired. .. On the other hand, regarding metal oxides, development of metal oxides having a particle size and shape suitable for enhancing the UV protection effect (see Patent Document 5), and surface treatment technology for improving the dispersibility and feel of these powders (see Patent Document 5). (See Patent Document 6) has been developed.

本発明の固形粉体化粧料は、成型性、使用感が良好でかつ高い紫外線防御効果を有するという効果を発揮する。 The solid powder cosmetic of the present invention exhibits the effects of having good moldability and usability and having a high ultraviolet protection effect.

以下、本発明を実施するための形態について詳細に説明する。ただし、本発明は以下の実施形態に限定されるものではない。 Hereinafter, embodiments for carrying out the present invention will be described in detail. However, the present invention is not limited to the following embodiments.

本発明の固形粉体化粧料に配合する球状粉体としては、化粧料に配合し得るものであれば特に限定されず、真球状のほか、楕円状や球状表面の一部又は全体に凹凸を有する略球状のものも用いることができる。また、球状であれば、全体が単一の成分で構成されるもの、コア−シェル型のように内核と外殻が異なる成分で構成されるもの、内部に異なる成分が分散しているもの、内部に空洞を有する中空粉体、更に内部に有益成分を内包、含浸させたもの等であっても特に制限されずに用いることができる。具体的には、無機球状粉体として、例えば、シリカ、酸化チタン、酸化亜鉛、酸化アルミニウム、炭酸カルシウム、酸化ジルコニウム、酸化セリウム等が挙げられ、有機球状粉体として、例えば、ナイロン粉体、ポリメタクリル酸メチル、オルガノポリシロキサンエラストマー、メチルシロキサン網状重合体、架橋型メチルポリシロキサン、ウレタン樹脂、ポリスチレン、アクリロニトリル−メタクリル酸共重合体、塩化ビニリデン−メタクリル酸共重合体、ポリエチレン、シルク、セルロース等が挙げられる。これらはフッ素系化合物、シリコーン系化合物、金属石鹸、レシチン、炭化水素、高級脂肪酸、高級アルコール、エステル、ワックス、界面活性剤等の1種または2種以上を用いて処理を施してあってもよい。 The spherical powder to be blended in the solid powder cosmetic of the present invention is not particularly limited as long as it can be blended in the cosmetic, and in addition to the true spherical shape, an elliptical shape or a part or the whole of the spherical surface is uneven. A substantially spherical object having a substantially spherical shape can also be used. In addition, if it is spherical, the whole is composed of a single component, the inner core and the outer shell are composed of different components such as a core-shell type, and different components are dispersed inside. Hollow powder having a cavity inside, and those containing or impregnating a beneficial component inside can be used without particular limitation. Specifically, examples of the inorganic spherical powder include silica, titanium oxide, zinc oxide, aluminum oxide, calcium carbonate, zirconium oxide, cerium oxide and the like, and examples of the organic spherical powder include nylon powder and poly. Methyl methacrylate, organopolysiloxane elastomer, methylsiloxane reticulated polymer, crosslinked methylpolysiloxane, urethane resin, polystyrene, acrylonitrile-methacrylic acid copolymer, vinylidene chloride-methacrylic acid copolymer, polyethylene, silk, cellulose, etc. Can be mentioned. These may be treated with one or more of fluorine-based compounds, silicone-based compounds, metal soaps, lecithin, hydrocarbons, higher fatty acids, higher alcohols, esters, waxes, surfactants and the like. ..

球状粉体は、本発明の固形粉体化粧料全量に対し、10〜30質量%配合する。10質量%未満の配合では、良好な使用感が得られない場合がある。30質量%を超えて配合すると、成型性の低下が認められる場合がある。 The spherical powder is blended in an amount of 10 to 30% by mass based on the total amount of the solid powder cosmetic of the present invention. If the composition is less than 10% by mass, a good feeling of use may not be obtained. If it is blended in an amount of more than 30% by mass, a decrease in moldability may be observed.

本発明の固形粉体化粧料に配合する平均粒子径が2μm以下の六角板状酸化亜鉛粒子を配合する。上記粒子径は、1.0μm以下であることがより好ましく、0.5μm以下であることが更に好ましい。また、粒子径の下限は特に限定されるものではないが、0.04μm以上であることが好ましく、更に好ましくは0.05μm以上である。粒子径が0.04μm未満であると、粒子径が小さすぎることによって、化粧料の使用感が悪化するおそれがある。 Hexagonal plate-shaped zinc oxide particles having an average particle diameter of 2 μm or less to be blended in the solid powder cosmetic of the present invention are blended. The particle size is more preferably 1.0 μm or less, and further preferably 0.5 μm or less. The lower limit of the particle size is not particularly limited, but is preferably 0.04 μm or more, and more preferably 0.05 μm or more. If the particle size is less than 0.04 μm, the feeling of use of the cosmetic may be deteriorated because the particle size is too small.

本明細書における六角板状酸化亜鉛粒子の粒子径は、透過型電子顕微鏡(TEM、JEM−1200EX II、日本電子社製)写真の2000〜50000倍の視野での定方向径(粒子を挟む一定方向の二本の平行線の間隔;画像上のどのような形状の粒子についても、一定方向で測定した)で定義される粒子径(μm)であって、TEM写真内の一次粒子250個の定方向径を計測し、その累積分布の平均値を求めたものである。 The particle size of the hexagonal plate-shaped zinc oxide particles in the present specification is a directional diameter (constant sandwiching the particles) in a field of view 2000 to 50,000 times that of a transmission electron microscope (TEM, JEM-1200EX II, manufactured by JEOL Ltd.). The particle size (μm) defined by the distance between two parallel lines in the direction (measured in a fixed direction for particles of any shape on the image), and 250 primary particles in the TEM photograph. The directional diameter was measured and the average value of the cumulative distribution was obtained.

本発明の六角板状酸化亜鉛粒子はその表面を、フッ素系化合物、シリコーン系化合物、金属石鹸、レシチン、炭化水素、高級脂肪酸、高級アルコール、エステル、ワックス、界面活性剤等の1種または2種以上を用いて処理を施してあってもよく、特にシリコーン化合物で処理を施したものを用いることが好ましい。 The hexagonal plate-shaped zinc oxide particles of the present invention have one or two types of fluorine-based compounds, silicone-based compounds, metal soaps, lecithin, hydrocarbons, higher fatty acids, higher alcohols, esters, waxes, surfactants, etc. on the surface thereof. The treatment may be carried out using the above, and it is particularly preferable to use one treated with a silicone compound.

表1に示した通り、本発明の固形粉体ファンデーションは、使用感、落下強度、UVB、UVA防御能のすべての面で優れていた。これに対し、球状粉体を7.5質量%配合した比較例1は、伸びが少し重く、少しきしみのある使用感であった。六角板状酸化亜鉛をマイカ、タルクに代替した比較例2、3は紫外線防御能、落下強度の面で劣っていた。複合板状粉体を配合していない比較例4は、伸びが重く、きしみのある使用感で、紫外線防御能も実施例には届かなかった。 As shown in Table 1, the solid powder foundation of the present invention was excellent in all aspects of usability, drop strength, UVB, and UVA protection ability. On the other hand, in Comparative Example 1 in which 7.5% by mass of the spherical powder was blended, the elongation was a little heavy and the feeling of use was slightly squeaky. Comparative Examples 2 and 3 in which hexagonal plate-shaped zinc oxide was replaced with mica and talc were inferior in terms of UV protection ability and drop intensity. Comparative Example 4 in which the composite plate-like powder was not blended had a heavy elongation and a squeaky feel, and the ultraviolet protection ability did not reach that of the examples.
