PROBLEM TO BE SOLVED: To provide a means for bringing the optical characteristic of a skin care external preparation such as a cosmetic ever closer to the optical characteristic of skin.SOLUTION: A cosmetic contains a polymer composite and a powder. In the polymer composite having inside a laminated structure of at least two kinds of polymer thin films having each different refractive index, its cross section is cut by a plane vertical to a laminate surface, and when putting the cut surface on an X-Y plane of a solid coordinate composed of three axes of X, Y and Z so that the Y-axis is in the vertical direction to the laminate surface, the length in the X-direction is 20-100 &mum, while the length in the Y-direction is 5-30 &mum, and the length in the Z-direction is 15-100 &mum.COPYRIGHT: (C)2012,JPO&INPIT【課題】化粧料などの皮膚外用剤において、その光学特性を更に皮膚の光学特性に近づける手段の提供。【解決手段】屈折率の異なる少なくとも2種の高分子薄膜の積層構造を内部に有する高分子複合体であって、その断面は積層面に対して垂直な平面で切断されたものであり、この切断面をX、Y及びZの3軸からなる立体座標のX-Y平面に積層面に垂直な方向をY軸となるように置いた場合、X方向の長さが20~100μmであり、Y方向の長さが5~30μmであり、Z方向の長さが15~100μmである高分子複合体及び該粉体を含有する化粧料。【選択図】なし
