This invention relates to a powder composition comprising a silicone represented by the following formula (1) comprising an alcoholic hydroxyl group, and a powder, to an oil-based powder composition formed by dispersing this powder composition in an oil, and to a cosmetic material containing these materials. R<1> aR<2> bSiO (4-a-b)/2 where, in formula (1), R<1> are identical or different organic groups selected from alkyl groups, aryl, aralkyl or fluorinated alkyl groups having 1-30 carbon atoms, R<2> is a substituent having one or more alcoholic hydroxy groups, and a, b are integers satisfying the relations: 1.0</=a</=2.5, 0.001</=b</=1, 1.5</=a+b</=2.6. The powder composition of this invention has little cohesion, excellent dispersibility and excellent stability over time as an oil-based powder composition. Therefore, cosmetics using these materials have excellent stability in use, and excellent stability over time.
