Description
本発明は、紫外線防御機能及び／又はカバー力を持ち、しっとり感や密着感に優れた固形粉末化粧料に関する。 TECHNICAL FIELD The present invention relates to a solid powder cosmetic having an ultraviolet protection function and/or covering power, and excellent moist feeling and adhesion feeling.
近年ではサンスクリーン剤や化粧下地のみならず、パウダーファンデーションなどの固形粉末化粧料においても紫外線防御機能が要求される。一般に紫外線防御機能を持つ多くの化粧料では紫外線吸収剤としてメトキシケイヒ酸エチルヘキシル等の油剤及び／又は紫外線散乱剤として酸化チタン、酸化亜鉛等の微粒子金属酸化物を使用する事で紫外線防御機能をもたせている。 In recent years, not only sunscreen agents and makeup bases, but also solid powder cosmetics such as powder foundations are required to have an ultraviolet protection function. In general, many cosmetics with UV protection function are provided with UV protection function by using oils such as ethylhexyl methoxycinnamate as UV absorbers and/or particulate metal oxides such as titanium oxide and zinc oxide as UV scattering agents. ing.
紫外線吸収剤をはじめとする油性成分は、適度に配合した場合には粉体に密着性、滑らかさ、しっとり感を与える。しかし過剰に配合するとベタツキが発生し、肌上での滑りや伸びの低下、塗りムラや化粧崩れ、またプレス製品においては取れの悪化やケーキングが発生しやすい。その為に紫外線吸収剤のベタツキを除去する方法が知られている（例えば、特許文献１参照）。また紫外線吸収剤は自身の酸化安定性が低く、多量に配合した際には特異臭が発生する事もある。さらに特定の製品中成分や容器材質の劣化を促進し商品不良が発生する事も知られている。それに加えて一部の消費者は油性の紫外線吸収剤に対して刺激を感じる事もある。従って油性成分、特に紫外線吸収剤の配合量は適量を見極める必要があり、紫外線吸収剤の配合量を増やす事による紫外線防御機能の向上は困難である。それゆえ紫外線吸収剤に依存せず、紫外線散乱剤によって紫外線防御機能を向上させる方法も広く知られている（例えば、特許文献２、３参照）。 Oily components such as UV absorbers impart adhesion, smoothness, and moistness to the powder when blended appropriately. However, if it is blended excessively, it tends to become sticky, resulting in reduced slippage and spreadability on the skin, uneven application and make-up failure, and worsening of removal and caking in pressed products. Therefore, a method for removing the stickiness of the ultraviolet absorber is known (see, for example, Patent Document 1). In addition, the ultraviolet absorber itself has low oxidation stability, and when mixed in a large amount, it may generate a peculiar odor. Furthermore, it is also known that it accelerates the deterioration of specific product components and container materials, resulting in product defects. In addition, some consumers may experience irritation with oil-based UV absorbers. Therefore, it is necessary to ascertain the appropriate amount of the oily component, especially the UV absorber, and it is difficult to improve the UV protection function by increasing the amount of the UV absorber. Therefore, methods for improving the UV protective function by using UV scattering agents without relying on UV absorbers are also widely known (see, for example, Patent Documents 2 and 3).
一方紫外線散乱剤は一般に酸化チタン、酸化亜鉛、酸化ジルコニウム、酸化セリウムなどの、金属酸化物を微粒子化して配合され、紫外線を散乱、吸収、反射等により遮蔽する。しかしこれらの微粒子金属酸化物を多量に配合する場合、分散性の悪化や、皮膚上での伸びの悪化が発生する。また粉っぽくかさついた感触となりやすい。さらに使用時に硬くなり取れが悪くなりケーキング等の不良が発生しやすい傾向がある。これを解決する手段として、微粒子金属酸化物に対し様々な表面処理を行う方法や、タルクやマイカ、セリサイト等の板状粉体、ポリメチルメタクリレート等の球状粉体の表面に微粒子金属酸化物を付着させた複合粉体を配合する方法を用いる技術が数多く知られている（例えば、特許文献４参照）。しかしいずれの方法も高い紫外線防御機能を求めた際に満足のいく使用性、分散性を得られるものではない。また表面処理や複合粉体は種類により高価となる場合も少なくない。従って紫外線散乱剤の配合量を増やす事は難しい。 On the other hand, UV scattering agents are generally blended by finely dividing metal oxides such as titanium oxide, zinc oxide, zirconium oxide and cerium oxide, and block UV rays by scattering, absorbing, reflecting and the like. However, when a large amount of these fine particulate metal oxides is mixed, deterioration of dispersibility and deterioration of spreadability on the skin occur. In addition, it tends to give a powdery and bulky feel. Furthermore, it tends to become hard and difficult to remove during use, and defects such as caking tend to occur. As a means to solve this problem, various surface treatments are applied to fine metal oxides, plate-like powders such as talc, mica, and sericite, and spherical powders such as polymethyl methacrylate are coated with fine metal oxide particles. There are many known techniques that use a method of blending a composite powder to which is attached (see, for example, Patent Document 4). However, none of these methods can provide satisfactory usability and dispersibility when a high UV protection function is desired. In addition, surface treatment and composite powder are often expensive depending on the type. Therefore, it is difficult to increase the compounding amount of the ultraviolet scattering agent.
例えば特許文献５のように紫外線散乱剤と紫外線吸収剤を併用する方法も広く行われているが、上記の通り紫外線散乱剤、紫外線吸収剤共にそれぞれの問題点により配合量を増やす事は困難である。それゆえ固形粉末化粧料において優れた使用性、分散性を持ちながら、高い紫外線防御能力を持つことは困難である。 For example, a method of using an ultraviolet scattering agent and an ultraviolet absorber together as in Patent Document 5 is also widely practiced, but as described above, it is difficult to increase the compounding amount of both the ultraviolet scattering agent and the ultraviolet absorber due to their respective problems. be. Therefore, it is difficult to have high UV protection ability while having excellent usability and dispersibility in solid powder cosmetics.
また微粒子金属酸化物は隠蔽性が高い事が知られており、カバー力（しみ、毛穴、しわ等、肌の色や凹凸を隠す力）を向上させるために多用されている。カバー力の高さから、その屈折率は２．０以上が好ましく、特に酸化チタン（屈折率２．６）や酸化亜鉛（屈折率２．１）が多く用いられている。しかし高いカバー力を実現するために微粒子金属酸化物を多く配合すると、分散性が低下し、滑らかな使用性を損なう。そこでタルクやマイカ、セリサイト等の板状粉体、ポリメチルメタクリレート等の球状粉体の表面に微粒子金属酸化物を付着させた複合粉体を配合する方法を用いる技術が数多く知られている。しかしいずれの方法も高いカバー力を求めた際に満足のいく使用性、分散性を得られるものではない。 In addition, fine metal oxide particles are known to have high concealing properties, and are often used to improve covering power (ability to hide skin color and irregularities such as spots, pores, wrinkles, etc.). The refractive index is preferably 2.0 or more because of its high covering power, and particularly titanium oxide (refractive index 2.6) and zinc oxide (refractive index 2.1) are often used. However, when a large amount of fine metal oxide particles is blended in order to achieve high covering power, dispersibility is lowered and smooth usability is impaired. Therefore, many techniques are known that use a method of blending a composite powder in which fine particles of metal oxide are adhered to the surface of plate-like powder such as talc, mica and sericite, or spherical powder such as polymethyl methacrylate. However, none of these methods can provide satisfactory usability and dispersibility when high covering power is desired.
本発明の目的は、紫外線防御機能及び／又はカバー力を持ち、しっとり感や密着感に優れた固形粉末化粧料を提供することにある。 SUMMARY OF THE INVENTION An object of the present invention is to provide a solid powder cosmetic which has an ultraviolet protection function and/or covering power and is excellent in moist feeling and adhesion feeling.
係る実情に鑑み、本発明者らは鋭意研究を重ねた結果、微粒子金属酸化物、油性成分、低粘度のジメチコノール、及びシリコーンエラストマーゲルを配合する事で、紫外線防御機能及び／又はカバー力を持ち、しっとり感や密着感に優れた固形粉末化粧料を得られることを見出し、本発明を完成するに至った。 In view of such circumstances, the present inventors have conducted extensive research and found that by blending fine particle metal oxides, oily components, low-viscosity dimethiconol, and silicone elastomer gel, UV protection and/or covering power can be obtained. , found that a solid powder cosmetic excellent in moist feeling and adhesion feeling can be obtained, and completed the present invention.

Examples of commercial products of dimethiconol having a kinematic viscosity of 120 mm 2 /s or less suitable for carrying out the present invention include YF-3800A and XC96-723 manufactured by Momentive Performance Materials Japan LLC. There is no need to set a lower limit for kinematic viscosity. For example, it may be 5 mm 2 /s or more, 15 mm 2 /s or more, or 30 mm 2 /s or more. A viscosity modifier may be used in combination.
ジメチコノールの配合量は１．０質量％以上である。配合量が１．０質量％未満であると本発明に掛かる効果が十分に得ることができない。配合量の上限は設定する必要がない。ケーキング防止や、粉体の分散性や流動性や吸油量などを踏まえて当業者が適量決定できる。 The content of dimethiconol is 1.0% by mass or more. If the blending amount is less than 1.0% by mass, the effects of the present invention cannot be sufficiently obtained. It is not necessary to set the upper limit of the compounding amount.

表１及び２の結果から明らかなように、低粘度ジメチコノール、油性成分、シリコーンエラストマーゲルを配合した場合（実施例１～８）は、ジメチコノールのみを配合した場合（比較例１）、ジメチコノールを配合しない場合（比較例６）、油性成分を配合しない場合（比較例５）、シリコーンエラストマーゲルを配合しない場合（比較例２、３）、不適切な粘度のジメチコノールを配合した場合（比較例４、７）と比較して、分散性、感触の滑らかさ、しっとり感、密着感に優れていることがわかる。 As is clear from the results in Tables 1 and 2, when low-viscosity dimethiconol, an oily component, and silicone elastomer gel were blended (Examples 1 to 8), only dimethiconol was blended (Comparative Example 1), and dimethiconol was blended. (Comparative Example 6), no oil component (Comparative Example 5), no silicone elastomer gel (Comparative Examples 2 and 3), and dimethiconol with an inappropriate viscosity (Comparative Example 4, Compared to 7), it is found to be excellent in dispersibility, smooth touch, moist feeling, and close contact feeling.
また、表３の結果から明らかなように、低粘度ジメチコノール、油性成分、シリコーンエラストマーゲルを配合した場合（実施例９～１０）は、シリコーンエラストマーゲルを配合しない場合（比較例８）、ジメチコノールを配合しない場合（比較例９）、油性成分を配合しない場合（比較例１０）と比較して、分散性、感触の滑らかさ、しっとり感、密着感に優れていることがわかる。
Moreover, as is clear from the results in Table 3, when low-viscosity dimethiconol, an oily component, and silicone elastomer gel were blended (Examples 9 and 10), when no silicone elastomer gel was blended (Comparative Example 8), dimethiconol was added. It can be seen that the case of not blending (Comparative Example 9) is superior to the case of not blending an oily component (Comparative Example 10) in terms of dispersibility, smoothness of touch, moist feeling, and adhesion.
