【発明の詳細な説明】
〔産業上の利用分野〕
本発明は化粧料に関し、更に詳しくは、紫外線防護効率
の優れた化粧料に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to cosmetics, and more particularly to cosmetics with excellent ultraviolet protection efficiency.
紫外線防護効果を有する従来の化粧料は、二酸化チタン
、酸化亜鉛、酸化鉄等の無機顔料、或し）はオキシベン
ゾン、ウロカニン酸、Ｐ−アミノ、安息香酸系誘導体、
サリチル酸系誘導体等の紫外線吸収剤を単独で或いは混
合して配合したものがあり、又紫外線透過防止能を有す
る物質即ち、無機顔料、紫外線吸収剤等を含有する球状
多孔性樹脂粉体を配合した化粧料（特開昭５７−１２０
５１４号公報）、ビニル重合体の粉末の中空部に紫外線
吸収剤を内包させた化粧料（特開昭６２−１９８６１２
号公報）、及び偏平粒状樹脂微粉末に紫外線吸収剤を含
有させた化粧料（特開昭６３−２９１９号公報）等が知
られている。Conventional cosmetics with UV protection effects include inorganic pigments such as titanium dioxide, zinc oxide, and iron oxide; or) oxybenzone, urocanic acid, P-amino, and benzoic acid derivatives.
There are products that contain ultraviolet absorbers such as salicylic acid derivatives alone or in combination, and products that contain spherical porous resin powder containing substances that have the ability to prevent ultraviolet transmission, such as inorganic pigments and ultraviolet absorbers. Cosmetics (JP-A-57-120
No. 514), a cosmetic containing an ultraviolet absorber encapsulated in the hollow part of vinyl polymer powder (Japanese Patent Laid-Open No. 62-198612)
JP-A No. 63-2919), and cosmetics containing ultraviolet absorbers in flat granular resin fine powder (JP-A-63-2919).
前記の通り、従来の紫外線防護効果を有する化粧料のよ
うに単に酸化チタン等や紫外線吸収剤を配合したもので
は、多量に配合しなければ効果がないため、例えば酸化
チタン等の場合、肌に塗布したとき隠蔽力が大きくなり
、又白っぽく自然さのない化粧仕上りとなるし、又紫外
線吸収剤では皮膚刺激などの安全性の問題が生ずる。そ
して。As mentioned above, conventional cosmetics with UV protection effects that simply contain titanium oxide or UV absorbers are ineffective unless they are added in large amounts. When applied, it has a large hiding power and gives a whitish, unnatural makeup finish, and ultraviolet absorbers pose safety issues such as skin irritation. and.
前記球状多孔質粉体に紫外線吸収剤を含有させたもので
は、球状粉体の表面そのものの特性が出て、紫外線吸収
剤の効力が充分に発揮されにくいものとなり、又ビニル
重合体の粉末中空部に紫外線吸収剤を内包させたもので
は、粉末そのものが持つ乱反射効果が優先し、紫外線が
紫外線吸収剤まで到達しにくくなり、紫外線吸収剤の効
力が充分発揮できないものとなることが推測される。そ
して、又偏平粒状樹脂微粉末に紫外線吸収剤を含有させ
たものでは偏平粒子のため、球状粉体に比して延展性が

紫外線吸収効果を最大限に発揮させることのできる化粧
料素材の開発が望まれているのが現状である。When the above-mentioned spherical porous powder contains an ultraviolet absorber, the characteristics of the surface of the spherical powder itself appear, making it difficult for the ultraviolet absorber to fully demonstrate its effectiveness. It is presumed that in the case of a powder containing an ultraviolet absorber, the diffuse reflection effect of the powder itself takes precedence, making it difficult for ultraviolet rays to reach the ultraviolet absorber, making it impossible for the ultraviolet absorber to fully demonstrate its effectiveness. . Furthermore, because of the flat particle shape of resin fine powder containing an ultraviolet absorber, its spreadability is inferior to that of spherical powder, and its uniform dispersibility in cosmetic systems is inferior, and it is also difficult to spread. It has been pointed out that this problem occurs, and there is currently a desire to develop cosmetic materials that can maximize the ultraviolet absorption effect of ultraviolet absorbers.

に到達したものである。As a result of intensive research into cosmetics that can maximize the ultraviolet absorption effect, the present inventors found that the surface of an inorganic powder, inorganic spherical powder, or organic spherical powder is coated and bonded with an ultraviolet absorber in advance. The present invention was achieved by discovering that a cosmetic containing cosmetic materials can solve the above-mentioned problems.

Examples include octyl methoxycinnamate, etc.), benzophenone ultraviolet absorbers, and others (oxybenzone, urocanic acid, etc.).
これらの粉体と紫外線吸収剤との量比は、９５：５〜６

ある。The ratio of these powders to the ultraviolet absorber is 95:5 to 6.
The ratio is 0:40, preferably 80:20 to 70:30.

なり好ましくない。If the amount ratio of UV absorber is low, the amount of coverage will be small, and when added to cosmetics, sufficient UV protection effect will not be obtained.
Furthermore, an ultraviolet absorber must be added during the manufacturing process, which is not preferable. On the other hand, when the amount ratio of the ultraviolet absorber increases, the amount of coating increases, and the powder tends to become lumpy (clumps).
They have poor blending (dispersion) properties in cosmetics and are not uniformly dispersed throughout the cosmetics, making it impossible to obtain a sufficient UV protection effect, which is undesirable.

できる。In the method for producing a cosmetic material of the present invention, by mixing and deaerating powder, particularly porous powder, the coating bond retention force is increased. Also, heating promotes coating bonding of the ultraviolet absorber to the powder. Furthermore, if a UV absorber is mixed and diluted in advance with 1 to 3 times the amount of a volatile oil with medium permeability such as cyclic silicone oil, low molecular weight hydrocarbon, or fluorocarbon, it is possible to coat and bond more evenly. can.

用性が悪くなり好ましくない。The blending ratio of the cosmetic material in which the surface of the powder used in the present invention is coated and bonded with an ultraviolet absorber is preferably 2 to 60% by weight, particularly preferably 10 to 40% by weight, based on the total amount of the cosmetic. If the blending ratio of the materials used in the present invention is lower than 2% by weight, the UV protection effect will be extremely reduced, which is not preferable. On the other hand, the blending ratio of the materials used in the present invention is 60% by weight.
If the amount is higher than that, the UV protection effect will not increase in proportion to the amount added, and the effects of the cosmetic ingredients themselves will be strong, resulting in poor spreadability, a thick and sticky feel, and poor usability. I don't like it.

結合していることがわかる。As shown in Figure 2, the ultraviolet transmittance of the material ① of the present invention is 0% (1), which indicates that it efficiently protects against ultraviolet rays, and therefore the ultraviolet absorber is powder. It can be seen that the surface is coated with powder. Furthermore, when material (2) is treated with a solvent, its ultraviolet transmittance is approximately 15% (2), and the UV protection effect is reduced. The transmittance is as high as about 40% (3), and the UV protection effect of the material of the present invention is much better. This indicates that in the material of the present invention, the ultraviolet absorber is difficult to dissolve into the solvent, and indicates that the ultraviolet absorber is bound to the powder. As described above, it can be seen that in the cosmetic material of the present invention, the ultraviolet absorber is coated and bonded to the powder surface.
