Description
本発明は、乳化化粧料に関する。 The present invention relates to an emulsified cosmetic.
従来、しみ・そばかす等のカバー力を高めるため、化粧料に酸化チタン等が用いられている。しかしながら、このような化粧料では、不自然な仕上がりになってしまうため、カバー力を有し、自然な仕上がりが得られる化粧料が検討されている。例えば、特許文献１には、平均粒径３０μｍ以下の酸化チタン被覆雲母と、微粒子酸化チタン及び／又は微粒子酸化亜鉛のシリコーン懸濁液を含有する乳化化粧料が記載され、特許文献２には、微粒子酸化チタンの粒径が１０〜１０００ｎｍである微粒子酸化チタンを含有している板状二酸化ケイ素粉体を含有する化粧料が記載されている。 Conventionally, titanium oxide or the like has been used in cosmetics in order to increase the covering power of spots, freckles, and the like. However, such a cosmetic has an unnatural finish, and therefore, a cosmetic having a covering power and a natural finish is being studied. For example, Patent Document 1 describes an emulsified cosmetic containing a titanium oxide-coated mica having an average particle size of 30 μm or less and a silicone suspension of fine particle titanium oxide and / or fine particle zinc oxide. A cosmetic containing a plate-like silicon dioxide powder containing finely divided titanium oxide having a particle diameter of finely divided titanium oxide of 10 to 1000 nm is described.
従来の化粧料では、波長制御ができないため、化粧後の仕上りが不自然であった。特に、カバー力を上げようとすると白浮きや厚ぼったさを感じてしまうという課題があった。 In conventional cosmetics, wavelength control is not possible, so the finish after makeup is unnatural. In particular, there was a problem that when trying to increase the covering power, the whiteness and thickness were felt.
本発明者らは、特定の板状粉体（緑色干渉色）で特定波長の反射を高め、特定の酸化鉄被覆酸化チタンの色みを反射させることで、肌全体を自然に仕上げることができ、白浮きや粉っぽさがなく、色ムラカバー力に優れ、厚ぼったくなく、きれいで明るい仕上りを実現する乳化化粧料が得られることを見出した。 The present inventors can finish the whole skin naturally by enhancing the reflection of a specific wavelength with a specific plate-like powder (green interference color) and reflecting the color of a specific iron oxide-coated titanium oxide. The present inventors have found that an emulsified cosmetic that does not have white float or powder, has excellent color unevenness covering power, is not thick, and has a clean and bright finish can be obtained.

実施例１２
表３に示す組成の水中油型乳化化粧料（化粧下地）を製造した。
得られた化粧料は、塗布後に自然な仕上がりで、白浮きがなく、粉っぽくない仕上がりで、色むらカバー力に優れ、厚ぼったくなく、きれいで明るい仕上がりが得られた。
Example 12
Oil-in-water emulsified cosmetics (makeup bases) having the compositions shown in Table 3 were produced.
The resulting cosmetics had a natural finish after application, had no white float, were not powdery, had excellent uneven color coverage, were not thick, and had a clean and bright finish.
（製法）
粉体相成分を混合粉砕し、油相成分を混合し、粉砕した粉体成分を添加して、ディスパーで分散した。さらに水相成分を混合し、油相と粉体の混合物に添加して、乳化した。その後、ホモミキサーで粘度調整して、水中油型乳化化粧料（化粧下地）を得た。
(Manufacturing method)
The powder phase component was mixed and pulverized, the oil phase component was mixed, and the pulverized powder component was added and dispersed with a disper. Furthermore, the water phase component was mixed and added to the mixture of the oil phase and the powder to emulsify. Thereafter, the viscosity was adjusted with a homomixer to obtain an oil-in-water emulsified cosmetic (makeup base).
