Abstract
Description
本発明は、乳化化粧料に関する。 The present invention relates to an emulsified cosmetic.
微粒子酸化亜鉛を含有した化粧料は、カバー効果や、なめらかな使用感などが得られることが知られている。
また、自然な仕上がりで、毛穴や小じわの目立ちを見え難くするための化粧料が検討されている。例えば、特許文献１には、白色顔料を含有した複合ポリマーを含有する化粧料が記載され、特許文献２には、顔料の表面を無機珪素化合物で被覆した被覆顔料を配合した化粧料が記載されている。
It is known that cosmetics containing particulate zinc oxide can provide a cover effect and a smooth feeling of use.
In addition, cosmetics are being studied to make pores and fine lines less visible with a natural finish. For example, Patent Document 1 describes a cosmetic containing a composite polymer containing a white pigment, and Patent Document 2 describes a cosmetic containing a coating pigment in which the surface of the pigment is coated with an inorganic silicon compound. ing.
本発明者らは、着色顔料、微粒子酸化亜鉛、パラメトキシケイ皮酸オクチルを含む乳化化粧料では、肌の凹凸や毛穴のカバー力に劣るため、毛穴が目立つという課題があり、また、毛穴をカバーするためにしっかり塗ろうとすると、白浮きや粉っぽさが目立ち、厚ぼったく仕上がるので、自然な仕上りに見えないという課題を見出した。 The present inventors have a problem that the emulsified cosmetic containing a color pigment, fine-particle zinc oxide, and octyl paramethoxycinnamate is inferior to the unevenness of the skin and the covering power of the pores. When I tried to apply it firmly to cover it, I found a problem that the white finish and powderiness were conspicuous and thickly finished, so it did not look natural.
本発明者らは、着色顔料、微粒子酸化亜鉛、パラメトキシケイ皮酸オクチルを含む乳化化粧料に、平均粒子径が０．６〜４μｍの酸化鉄被覆酸化チタンを特定の割合で組み合わせて用いることにより、肌の皮丘・皮溝への付着性に優れ、毛穴の有無に影響されず、化粧後の肌の毛穴の目立ちを抑え、白浮きや粉っぽさを抑制し、厚ぼったくないきれいな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 use an emulsified cosmetic containing a color pigment, fine particle zinc oxide, and octyl paramethoxycinnamate in combination with iron oxide-coated titanium oxide having an average particle size of 0.6 to 4 μm in a specific ratio. Excellent adhesion to the skin dermis and skin groove, unaffected by the presence or absence of pores, suppresses noticeable pores in the skin after makeup, suppresses whitening and powderiness, and produces a clean finish that is not too thick It was found that an emulsified cosmetic material that achieves the above can be obtained.
本発明は、次の成分（Ａ）、（Ｂ）、（Ｃ）及び（Ｄ）：
（Ａ）平均粒子径０．６〜４μｍの酸化鉄被覆酸化チタン ０．４〜１２質量％、
（Ｂ）成分（Ａ）及び（Ｃ）を除く、着色顔料 ０．１〜２０質量％、
（Ｃ）比表面積１０〜１００ｍ2／ｇの微粒子酸化亜鉛、
（Ｄ）パラメトキシケイ皮酸オクチル
を含有し、成分（Ｂ）に対する成分（Ａ）の質量割合（Ａ）／（Ｂ）が、０．０５〜１０である乳化化粧料に関する。
The present invention includes the following components (A), (B), (C) and (D):
(A) 0.4 to 12% by mass of iron oxide-coated titanium oxide having an average particle size of 0.6 to 4 μm,
(B) Color pigment 0.1 to 20% by mass, excluding components (A) and (C)
(C) fine particle zinc oxide having a specific surface area of 10 to 100 m 2 / g,
(D) It is related with the emulsified cosmetics which contain octyl paramethoxycinnamate and the mass ratio (A) / (B) of the component (A) with respect to a component (B) is 0.05-10.
本発明の乳化化粧料は、化粧後の肌の毛穴の目立ちやキメの乱れを抑え、白浮きや粉っぽさを抑制し、厚ぼったくなく、均一できれいな仕上りを得ることができる。 The emulsified cosmetic of the present invention can suppress the conspicuous pores and texture of the skin after makeup, suppress whitening and powderiness, and can obtain a uniform and clean finish without being thick.
本発明で用いられる成分（Ａ）は、平均粒子径が０．６〜４μｍの酸化鉄被覆酸化チタンである。
ここで用いる酸化チタンは、平均粒子径が０．６〜４μｍであり、０．６〜３μｍであるのが好ましく、０．７〜２μｍがより好ましく、０．８〜１．５μｍがさらに好ましい。
