Definitions
- the present invention relates to porous pigment particles containing cellulose or a cellulose derivative, a method for producing the same, and cosmetics containing the particles.
- Inorganic pigment refers to an inorganic substance that is almost insoluble in water or organic solvents used for coloring. Inorganic pigments are inferior to organic pigments in terms of vividness of color and the like, but are excellent in light resistance, heat resistance and concealing property. For example, in cosmetics, they are used to impart coloring property and covering property. However, while the inorganic pigment has excellent solvent resistance, aggregation may occur in the base material. Aggregation of inorganic pigments causes a decrease in usability and a dull color in the cosmetics to be blended.
- An object of the present invention is to suppress the deterioration of the usability of cosmetics containing an inorganic pigment and the aggregation of the inorganic pigment that causes the color to be dull.
- the present inventors have been diligently studying particles containing cellulose or a cellulose derivative in anticipation of the development of a defocus effect (also referred to as a soft focus effect), but the present inventors have been diligently studying particles containing an inorganic pigment and cellulose or a cellulose derivative.
- the sex pigment particles are excellent in dispersibility in a base material, improve the dullness of color, suppress the aggregation of pigments, and are soft and comfortable to use due to the cellulose on the particle surface.
- the present invention is as follows.
- Porous pigment particles containing cellulose or a cellulose derivative and an inorganic pigment as main components (2) The particles according to (1) above, which have a porosity in the range of 5 to 50%. (3) The particles according to (1) or (2) above, which have a particle size in the range of 0.1 to 500 ⁇ m. (4) The particle according to any one of (1) to (3) above, wherein the light scattering rate is in the range of 50 to 230%. (5) In the measurement of the reflected light distribution, the ratio of the intensity of the reflected light in the vicinity of the regular reflection to the incident light to the intensity of the reflected light in the vicinity of the incident light is in the range of 0.5: 1 to 2: 1. The particle according to any one of (1) to (4).
- the inorganic pigment is at least one selected from the group consisting of white pigments, coloring pigments, pearl luster pigments and functional pigments.
- the inorganic pigment is selected from the group consisting of Bengara, yellow iron oxide, black iron oxide, chromium oxide, ultramarine blue, titanium oxide, zinc oxide, aluminum oxide, boron nitride and barium sulfate.
- a porous pigment particle containing cellulose or a cellulose derivative and an inorganic pigment as a main component which comprises a step of obtaining a dispersion liquid containing cellulose or a cellulose derivative and an inorganic pigment and a step of spray-drying the obtained dispersion liquid.
- Production method. (11) The production method according to (10) above, wherein the dispersion is obtained by physically pulverizing cellulose or a cellulose derivative and an inorganic pigment.
- the porous pigment particles of the present invention suppress agglomeration and are excellent in dispersibility in a base material, so that the dullness of color can be improved. Specifically, by providing the inorganic pigment as the porous pigment particles of the present invention, it is possible to improve the lightness of the white pigment and deepen the color of the colored pigment. Further, since the particles of the present invention are porous particles containing cellulose and having a wrinkle-like or fold-like uneven structure on the surface thereof (that is, pores or voids are appropriately present), they are soft and excellent in usability. Suitable for addition to cosmetics that come into direct contact with the skin.
- the particles of the present invention have an excellent optical property (light scattering property) that incident light is uniformly scattered, they can be blended in cosmetics such as foundation to have a defocus effect (also referred to as a soft focus effect). Can also be expected to occur.

- the porous pigment particles of the present invention suppress agglomeration and are excellent in dispersibility in a base material, so that the dullness of color can be improved. Further, since the particles of the present invention are porous particles containing cellulose and having a wrinkle-like or fold-like uneven structure on the surface thereof (that is, pores or voids are appropriately present), they are soft and excellent in usability. Suitable for addition to cosmetics that come into direct contact with the skin. Furthermore, since the particles of the present invention have an excellent optical property (light scattering property) in which incident light is uniformly scattered, a defocus effect (also referred to as a soft focus effect) can be expected to occur, so that the particles are directly applied to the skin. It is preferably applied to the field of touching cosmetics.

本発明は、セルロース又はセルロース誘導体と無機顔料を主成分として含む、多孔性顔料粒子に関する。本発明の「多孔性」とは、顔料粒子の表面に凹凸があり、複数の細孔を有することを意味する。具体的に、本発明の多孔性顔料粒子は、粒子の拡大像を観察した際に、皺状又は襞状の外観を有する溝状の筋目(凹凸構造)を有する。本発明の多孔性粒子は、後述する所定の範囲の空隙率を有するか、あるいは後述する実施例に記載されたような水銀圧入法による細孔分布測定において、0.1m2/g以上、好ましくは1m2/g以上、より好ましくは5m2/g以上であって、100m2/g以下、好ましくは50m2/g以下、より好ましくは30m2/g以下である細孔表面積を有することで特徴づけることができる。
本発明の粒子は、下記式(1)で表される光散乱率が、50~230%の範囲にあることを特徴とする。
{式(1)中、角度20°、70°及び5°での反射強度は、粒子に対して法線方向を0°として、粒子に-30°の角度から光を入射した時の受光器の感度を任意の値(感度調整値と呼ぶ)に設定した後、ある角度から光を入射した時の受光器の角度が20°、70°及び5°における反射光の強度を意味する。}
本発明の粒子は、セルロース又はセルロース誘導体と無機顔料との分散液を得る工程と、得られた分散液を噴霧乾燥する工程を含む方法により製造できる。
本発明の多孔性顔料粒子は、凝集が抑制され、基材への分散性に優れることから、色彩のくすみを改善することができるので、彩色性、被覆性、隠蔽性を要する化粧品又は医薬部外品への添加に適している。また本発明の粒子は、セルロースを含み、その表面に皺状又は襞状の凹凸構造を有し、その内部に適度な細孔と空隙を有することから柔らかく、使用感に優れる点からも、肌に直接触れる化粧品への添加に適している。本発明の粒子はまた入射光が均一に光散乱するという優れた光学特性(光散乱性)を有することから、肌に直接触れ、かつデフォーカス効果等の光学特性が要求される化粧品への添加に特に適している。そのような化粧品の例としては、ローション、ジェル、エマルション等のスキンケア製品、洗顔フォーム、洗顔パウダー、ボディ洗浄料等のトイレタリー製品、シャンプー、コンディショナー等のヘアケア製品、歯磨剤等のオーラルケア製品、化粧下地、パウダーファンデーション、リキッドファンデーション、BBクリーム、コンシーラー、口紅、日焼け止め等のメーキャップ化粧品等が挙げられ、これらにおいて、無機顔料として、又はデフォーカス効果を発現させるための光散乱剤として使用できる。
