PROBLEM TO BE SOLVED: To provide a coated powder in which the dispersibility of the powder and the function which the powder has, and especially the affinity to a lipophilic liquid are excellent and the dispersibility or dispersion stability is excellent when surface treatment is performed to the powder for cosmetics, and which is applicable also to the powder of the field of cosmetics or others.SOLUTION: The surface-treated powder includes: a powder which can be used for cosmetics surface treating agent coated layers which are the following layer A and layer B formed on at least a part of the surface of the particle, wherein the layer A is covered on at least a part of the particle surface, furthermore the layer B is covered on the layer A. The layer A is a layer coated with an ordinary temperature solid-like surface treating agent containing a compound selected from fatty acids. The layer B is a layer coated with an ordinary temperature liquid-like surface treating agent containing a compound selected from a one side terminal functional group-modified organopolysiloxane, a one side terminal functional group-modified alkylsilane, and a branched fatty acid.COPYRIGHT: (C)2011,JPO&INPIT【課題】化粧料用粉体に表面処理を施したときに、粉体の分散性と粉体の持つ機能、特に親油性液体への親和性が良く分散性や分散安定性に優れ、化粧料やその他の分野の粉体にも適用可能な被覆粉体を提供する。【解決手段】化粧料に使用可能な粉体と、その粒子表面の少なくとも一部上に形成された下記A層及びB層の表面処理剤被覆層とを含有し、当該粒子表面の少なくとも一部上において、A層が被覆され、更にその上にB層が被覆される表面処理粉体、A層:脂肪酸の中から選択される化合物を含有する常温で固体状の表面処理剤被覆層;及びB層:片末端官能基変性オルガノポリシロキサン、片末端官能基変性アルキルシラン及び分岐脂肪酸の中から選択される化合物を含有する常温で液体状の表面処理剤被覆層。【選択図】なし
