PROBLEM TO BE SOLVED: To provide an unsaturated fatty acid adsorbent which is excellent in absorbing ability of an unsaturated fatty acid as the main component of sebum which causes makeup deterioration and a cosmetic containing the same, and to provide an unsaturated fatty acid adsorbent which is more excellent in touch feeling than particulate zinc oxide conventionally known as a sebum adsorbent and has high ultraviolet shielding performance.SOLUTION: There is provided an unsaturated fatty acid adsorbent composed of a plate-like integrated spherical zinc oxide having a median diameter of 0.01 μm to less than 10 μm in which the lower limit preferably is 0.05 μm or more, more preferably 0.1 μm, further more preferably 0.2 μm or more, a D90/D10 of 5.0 or less, preferably 4.0 or less and more preferably 3.0 or less and a BET specific surface area of preferably 1.0 to less than 15 m2/g.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】化粧崩れの原因となる、皮脂の主成分である不飽和脂肪酸の吸着能力に優れた不飽和脂肪酸吸着剤とそれを含有する化粧料であり、また、従来から皮脂吸着材として知られている微粒子酸化亜鉛よりも感触に優れ、かつ高い紫外線遮蔽性能を持ち合わせた不飽和脂肪酸吸着剤の提供。【解決手段】メジアン径0.01~10μm未満で、好ましくは下限が0.05μm以上、より好ましくは0.1μm、更に好ましくは0.2μm以上であり、D90/D10が5.0以下、好ましくは4.0以下、より好ましくは3.0以下であり、BET比表面積が1.0~15m2/g未満であることが好ましい板状集積型球状酸化亜鉛からなる不飽和脂肪酸吸着剤。【選択図】なし
