Description

粉末固形化粧料Powder solid cosmetics
 本発明は、粉末固形化粧料に関する。より詳しくは、弾性球状粉末を実質的に配合しなくても優れた使用性を実現でき、なおかつ、高い耐衝撃性を備える粉末固形化粧料に関する。 The present invention relates to powdered solid cosmetics. More specifically, the present invention relates to a powder solid cosmetic which can realize excellent usability without substantially blending an elastic spherical powder and has high impact resistance.
 粉末固形化粧料は、ファンデーションやアイシャドウ等のメーキャップ化粧料に汎用されている化粧料基剤である。一般に粉末固形化粧料は、主成分である粉末とその結合剤または付着剤として作用する油分とによって構成されている。粉末部分は、化粧料の主要な基材となるため、肌上での伸び、なめらかさ、均一な仕上がりといった使用性に大きな影響を与える。なかでも球状粉末は、皮膚上で転がることにより滑り性を向上させ、伸び広がりが軽く、さらっとした仕上がり感を実現するうえで重要な役割を有する。 Powdered solid cosmetics are cosmetic bases that are widely used in makeup cosmetics such as foundations and eye shadows. In general, powdered solid cosmetics are composed of a powder as a main component and an oil component acting as a binder or an adhesive thereof. Since the powder portion is the main base material of cosmetics, it has a great influence on usability such as spread on the skin, smoothness, and uniform finish. Among them, the spherical powder has an important role in improving the slipperiness by rolling on the skin, spreading lightly, and realizing a smooth finish.
 パウダーファンデーション等の粉末固形化粧料における球状粉末としては、特に感触のなめらかさや柔らかさを向上させるために、ポリメチルメタクリレート(PMMA)粉末、ナイロン粉末、ウレタン粉末等の合成樹脂粉末が用いられることが多い。 As the spherical powder in powder solid cosmetics such as powder foundation, synthetic resin powder such as polymethylmethacrylate (PMMA) powder, nylon powder, urethane powder, etc. may be used in order to improve the smoothness and softness of the feel. There are many.
 しかしながら、これらのうち比較的柔軟性の高い弾性球状粉末は、球状のため他の粉末との接触面が小さくなるうえに、その弾力性により固化が難しく成形性に劣る。このため、粉末固形化粧料に優れた使用性を付与することはできても、同時に十分な耐衝撃性を実現することは難しい。
 これまでに、弾性球状粉末を含む粉末固形化粧料の耐衝撃性を改善する多くの試みがなされている。例えば、結合剤としてガス中蒸発法により微粒化された固形油粉末を用いること(特許文献1)、球状ポリオレフィン樹脂粉末を配合すること(特許文献2)、特定構造の回転翼対向型混合装置を用いること(特許文献3)などが提案されている。しかし、特定の原料や特定の装置を用いなければならないといった制限を受けるほか、耐衝撃性を十分なレベルにまで改善することは依然として難しい。
However, among these, the elastic spherical powder having relatively high flexibility has a small contact surface with other powders because it is spherical, and its elasticity makes it difficult to solidify and is inferior in moldability. Therefore, although it is possible to impart excellent usability to the powdered solid cosmetics, it is difficult to realize sufficient impact resistance at the same time.
So far, many attempts have been made to improve the impact resistance of powdered solid cosmetics containing elastic spherical powder. For example, a solid oil powder atomized by an evaporation method in gas may be used as a binder (Patent Document 1), a spherical polyolefin resin powder may be blended (Patent Document 2), and a rotary blade facing mixing device having a specific structure may be used. It has been proposed to use it (Patent Document 3). However, in addition to the restrictions of having to use specific raw materials and specific equipment, it is still difficult to improve the impact resistance to a sufficient level.
 このような事情から、弾性球状粉末を配合することなく、優れた使用性と耐衝撃性とを両立するための新しい技術が求められている。 Under these circumstances, a new technology is required to achieve both excellent usability and impact resistance without blending elastic spherical powder.

 本発明は、前記実情に鑑みてなされたものであり、弾性球状粉末を配合した場合と同様の使用性を有しながら、十分な耐衝撃性を備える粉末固形化粧料を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a powdered solid cosmetic having sufficient impact resistance while having the same usability as when an elastic spherical powder is blended.

As shown in Table 4, (A) mica, (B) spherical silicic acid anhydride, and (C) boron nitride are contained, and the blending amounts of the components (A) to (C) are all of the above-mentioned predetermined blending amount conditions. When the above conditions were met, good results were obtained in both usability and impact resistance (Examples 10 to 11).
On the other hand, when the total amount of (B) and (C) deviates from the above conditions, or when the total amount of (A), (B) and (C) deviates from the above conditions, in terms of usability or impact resistance. Insufficient results were obtained (Comparative Examples 7 to 8).
<実施例12及び比較例9>
 以下の表5に掲げた実施例12及び比較例9の粉末固形化粧料を、実施例1と同様に乾式製法で調製した。
 得られた粉末固形化粧料について、上記項目を評価した。評価結果を表5に併せて示す。
<Example 12 and Comparative Example 9>
The powdered solid cosmetics of Example 12 and Comparative Example 9 listed in Table 5 below were prepared by a dry method in the same manner as in Example 1.
The above items were evaluated for the obtained powdered solid cosmetics. The evaluation results are also shown in Table 5.

 表5に示されるように、(B)球状無水ケイ酸と(C)窒化ホウ素を配合せずに、ナイロン粉末やメタクリル酸メチルクロスポリマー粉末といった従来から使用性改善のために広く用いられている弾性球状粉末を配合した場合には、使用性は優れているものの、耐衝撃性が劣る結果となった(比較例9)。
 これに対し、(A)雲母、(B)球状無水ケイ酸、及び(C)窒化ホウ素を含み、成分(A)~(C)の配合量が上記所定の配合量条件の全てを満たす場合には、弾性球状粉末を配合した比較例9と同様の使用性を有しつつ、耐衝撃性においても良好な結果が得られた(実施例12)。
As shown in Table 5, it has been widely used for improving usability, such as nylon powder and methyl methacrylate crosspolymer powder, without blending (B) spherical anhydrous silicic acid and (C) boron nitride. When the elastic spherical powder was blended, the usability was excellent, but the impact resistance was inferior (Comparative Example 9).
On the other hand, when (A) mica, (B) spherical anhydrous silicic acid, and (C) boron nitride are contained, and the blending amounts of the components (A) to (C) satisfy all of the above-mentioned predetermined blending amount conditions. Has the same usability as Comparative Example 9 in which the elastic spherical powder is blended, and good results are obtained in terms of impact resistance (Example 12).
 以下に、本発明の化粧料の処方を例示する。本発明はこれらの処方例によって何ら限定されるものではなく、特許請求の範囲によって特定されるものであることはいうまでもない。なお、配合量は全て化粧料全体に対する質量%で表す。 The formulation of the cosmetic of the present invention is illustrated below. It goes without saying that the present invention is not limited to these prescription examples, and is specified by the scope of claims. In addition, all the compounding amounts are expressed by mass% with respect to the whole cosmetics.
