<p><P>PROBLEM TO BE SOLVED: To provide a cosmetic composition having all of transparency, ultraviolet-shielding property of UV-A range (320-400 nm) and wide-angle scattering property of uniformly scattering light over a wide range, and further low in cost. <P>SOLUTION: The cosmetic composition includes star-shaped zinc oxide particles each having a star shape and containing zinc oxide as a main substance thereof. An embodiment, wherein the star-shaped zinc oxide particles are formed by accumulating microparticles having a diameter of 1-100 nm so that crystallographic orientations thereof are aligned in the same direction, and are allowed to grow in a branched manner, and the star-shaped zinc oxide particles have an average particle diameter of 1-3μm, and an embodiment, wherein the cosmetic composition is a foundation, are preferable. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
