PROBLEM TO BE SOLVED: To provide a colored organic silicone fine particles whose surface could be uniformly colored comparatively simply with good workability and which are excellent in spreadability and adhesion to the skin when used as a cosmetic raw material, are hard to lose the makeup due to a film, and simultaneously has a plurality of desired performance characteristics such as excellent opacifying power for blotches as well.SOLUTION: The colored organic silicone fine particles are prepared by attaching a water insoluble vegetable pigment to the surface of an organic silicone fine particles which are composed of a polysiloxane crosslinked structure and present hollow hemic-spheroids as a whole formed of, viewed from its cross-section, an inner smaller minor arc (11), an outer larger minor arc (21) covering this inner smaller minor arc, and a ridge (31) ranging from the end of the inner smaller minor arc to that of the outer larger minor arc with an average value of the width (W1) between the ends of the inner smaller minor arc (11) of 0.01-9.5 &mum, an average value of the width (W2) between the ends of the outer larger minor arc (21) of 0.05-10 &mum, and an average value of the height (H) of the outer larger minor arc (21) of 0.015-9 &mum.COPYRIGHT: (C)2009,JPO&INPIT【課題】比較的簡単に作業性良く表面を均一着色したものとすることができ、それを化粧品原料として使用する場合には肌へののりや密着性に優れ、皮膜によって化粧落ちし難く、しみ等の隠ぺい力にも優れる等、望まれる複数の性能を同時に有する着色有機シリコーン微粒子を提供する。【解決手段】下記の有機シリコーン微粒子の表面に水不溶性植物色素を付着させた。有機シリコーン微粒子:ポリシロキサン架橋構造体から成る有機シリコーン微粒子であって、縦断面で見て内側小劣弧(11)とこれを覆う外側大劣弧(21)と双方の端部間に渡る稜線(31)とで形成された、全体としては中空半球状体様を呈し、内側小劣弧(11)の端部間の幅(W1)の平均値が0.01~9.5μm、外側大劣弧(21)の端部間の幅(W2)の平均値が0.05~10μm、且つ外側大劣弧(21)の高さ(H)の平均値が0.015~9μmの範囲内にある有機シリコーン微粒子。【選択図】図1
