Summary:PROBLEM TO BE SOLVED: To provide a coated dustless powder material containing a powder material having a surface layer that is chemically immobilized with one or more surface-active agents and coated with an oil.SOLUTION: The surface-active agents are present in an amount of at least about 0.1 wt.%, based on the powder material; the oil is present in an amount ranging from about 0.1 to 180 wt.%, based on the powder material; and the combined weight percentage of the surface-active agents and oil is at least about 4.0 wt.%, based on the powder material. The oil-absorption rate of the powder material ranges from about 0.01 to about 0.70 gram of oil per gram of dry powder. The coated powder material is useful as a cosmetic. 【課題】１つ以上の界面活性剤で化学的に固定され、油でコーティングされた、表面層を有するパウダー原料を含む、コーティングされた粉のたたないパウダー原料の提供。【解決手段】界面活性剤は、パウダー原料に基づいて、少なくとも約０．１重量％の量で存在し；油は、前記パウダー原料に基づいて、約０．１〜１８０重量％の範囲；そして、前記界面活性剤と油とを合わせた重量のパーセンテージは、前記パウダー原料に基づいて、少なくとも約４．０重量％である粉のたたないパウダー原料。前記パウダー原料の油吸収速度は、乾燥パウダーの１グラム当り約０．０１〜約０．７０グラムの範囲にわたるコーティングされたパウダー原料。前記コーティングされたパウダー原料は、化粧品として有用である。【選択図】なし
