This cosmetic for shower use contains as an essential ingredient a polyethylene glycol (PEG)/polyoxypropylene glycol (PPG) copolymer. The cosmetic for shower use preferably further contains polyvinyl alcohol (PVA), and more preferably a beautifying agent. Due to this feature, a constant rate of elution in cold or hot water can be ensured, while also minimizing excessive solubility so as to afford satisfactory persistence of solid shape.沐浴用化妝劑係含有聚氧化乙烯二醇(PEG)/聚氧化丙烯二醇(PPG)共聚物作為必要成分。此沐浴用化妝劑較佳係含有聚乙烯醇(PVA),更佳係含有美容劑。藉由此種構成,除了可以確保對冷水或溫水保有一定的溶出量,更可抑制過度溶解性,而可獲得固體形狀之充足持續性。50‧‧‧匣51‧‧‧匣殼51a‧‧‧槽縫51b‧‧‧閥室51c‧‧‧開口(流入口)52‧‧‧鴨嘴閥52b‧‧‧前端部53‧‧‧內管(連通路徑)53c‧‧‧連通孔(連通部)54‧‧‧藥劑收容部(化妝劑收納部)55‧‧‧出口組件57‧‧‧濾網61‧‧‧蓋組件100‧‧‧沐浴用化妝劑101‧‧‧空間
