PROBLEM TO BE SOLVED: To provide a method for easily producing a solid powdered cosmetic with impact strength and molding yield made compatible with each other.SOLUTION: The method for producing a solid powdered cosmetic comprises the following processes: a raw material powder 10 is filled in a molding recess 34 followed by pressing the powder 10 by an upper pestle 32 or the raw material powder 10 is set in a state of being filled in a molding recess 34 in between an upper pestle 32 and lower pestle 33 followed by pressing the powder 10 in between both of the pestles 32 and 33. In this method, the molding recess 34 is such that: the contour 34 of the inner wall 34a is of a polygonal shape when viewed from above, having three or more straight-line sides 22 and corners 23 each situated in between two sides 22 adjacent to each other. Specifically, the press molding operation is conducted under the condition: t2>t1 in such a state that the upper pestle 32 and the raw material powder 10 are in contact with each other, wherein t1 is the gap between the upper pestle 32 and the inner wall 34a of the recess 34 at each of the corners 23, and t2 is the gap between the upper pestle 32 and the inner wall 34a of the recess 34 at each of the sides 22.COPYRIGHT: (C)2013,JPO&INPIT【課題】耐衝撃性と成形収率との両立が図られた固形粉末化粧料を容易に製造できる方法を提供すること。【解決手段】成形用凹部34内に原料粉末10’を充填し上杵32によって該原料粉末10’をプレスするか、又は、上杵32と下杵33との間に、原料粉末10’を成形用凹部34内に充填した状態で配置し、両杵間で該原料粉末10’をプレスして固形粉末化粧料10を製造する方法である。成形用凹部34は、平面視での内壁34aの輪郭34’が、3本以上の直線状の辺部22と、隣り合う2本の辺部22間に位置するコーナー部23とを備えた多角形の形状である。上杵32と原料粉末10’とが当接している状態において、コーナー部23での上杵32と成形用凹部34の内壁34aとの隙間をt1とし、辺部22での上杵32と成形用凹部34の内壁34aとの隙間をt2としたとき、t2>t1となる条件下にプレス成形を行う。【選択図】図3
