Description

化粧料Cosmetics
　本発明は、化粧料に関する。 The present invention relates to cosmetics.
　化粧料は人の肌に塗布して使用するものであるため、皮膚から出る汗や皮脂への耐性が要求され、一般的に油浮きや化粧崩れしないことが求められる。このような要求を満たすため、化粧料に用いる粉体に様々な改良を加えることにより、化粧崩れを防止する検討が行われている。 Since cosmetics are applied to human skin and used, resistance to sweat and sebum from the skin is required, and generally it is required that oil floats and makeup does not come off. In order to meet such demands, studies have been made to prevent makeup from collapsing by making various improvements to powders used in cosmetics.
　例えば、多孔質シリカや多孔質球状炭酸マグネシウム等の無機多孔質粉体を化粧料に配合する方法が挙げられるが、これらの粉体は肌上の水分を吸収し、肌のエモリエント成分が不足して肌の乾燥やかゆみを引き起こすという問題がある（特許文献１及び特許文献２）。また、その他にもアクリルポリマー等の有機粉体が皮脂吸着剤として使用されているが、これらの皮脂吸着剤よりも、更に優れた皮脂吸着能を有する素材の開発が期待されている。 For example, there is a method of blending inorganic porous powders such as porous silica and porous spherical magnesium carbonate into cosmetics, but these powders absorb moisture on the skin and lack skin emollient components. There is a problem of causing dryness and itching of the skin (Patent Document 1 and Patent Document 2). In addition, organic powders such as acrylic polymers are used as sebum adsorbents, and the development of materials having even better sebum adsorbing ability than these sebum adsorbents is expected.
　一方、酸化亜鉛は化粧料分野ではその粒子サイズによって白色顔料や紫外線遮蔽材料として利用されている。例えば、微粒子酸化亜鉛は皮脂中の脂肪酸と反応して皮脂を固定化させ、皮脂の広がりを抑制することにより、化粧持ちを向上させることが知られている（特許文献３）。しかしながら、このような微粒子酸化亜鉛は化粧料に配合するとキシミ感が出てしまい、感触に劣るという欠点がある。このため、感触に優れ、かつ高い皮脂固化能を有する酸化亜鉛粒子を得ることができれば、化粧品分野においては非常に有用な素材になる。 On the other hand, zinc oxide is used as a white pigment and an ultraviolet shielding material in the cosmetics field depending on its particle size. For example, it is known that fine particle zinc oxide reacts with fatty acids in sebum to immobilize sebum and suppress the spread of sebum to improve makeup retention (Patent Document 3). However, such fine particle zinc oxide has a drawback that when it is blended with cosmetics, it gives a squeaky feeling and is inferior in feel. Therefore, if zinc oxide particles having an excellent feel and a high sebum solidifying ability can be obtained, it will be a very useful material in the field of cosmetics.
　また、（アクリレーツ／アクリル酸エチルへキシル）クロスポリマー１質量部に対し、酸化亜鉛を０．２～２質量部被覆した複合粉体（特許文献４）も知られているが、さらに高い皮脂固化能を発揮する粉体及び化粧料が求められている。 Further, a composite powder (Patent Document 4) in which 0.2 to 2 parts by mass of zinc oxide is coated on 1 part by mass of a crosspolymer (Acrylate / ethyl hexyl acrylate) is also known, but the sebum solidification is even higher. There is a demand for powders and cosmetics that exhibit their abilities.
