PROBLEM TO BE SOLVED: To provide a method for preventing the discoloring with time of a minoxidil-containing hair grower, whereas although the discoloring of the minoxidil-containing hair grower can be suppressed to some degree by using a container made from a material entirely blocking light, the content cannot be discriminated, while a container made from a transparent material such as a glass container can hardly prevent the discoloring with time due to low light shielding property.SOLUTION: The method for preventing discoloring of a minoxidil-containing hair grower comprises filling the agent in a container substantially formed from polyethylene terephthalate plastic. Further, a container filled with the minoxidil-containing hair grower, which is substantially formed from polyethylene terephthalate plastic is also provided.COPYRIGHT: (C)2012,JPO&INPIT【課題】ミノキシジルを配合した育毛剤の容器としては、光を全く遮断する材質のものを用いればある程度変色を抑えうるが、それでは内容物を判別できない。一方、ガラス容器のごとき透明な材質のものは遮光性が低く経時的な変色を防ぐことが困難であった。ミノキシジルを配合した育毛剤の経時的な着色を防止する方法の提供。【解決手段】実質的にポリエチレンテレフタレート製プラスチックで構成される容器に充填することを特徴とする、ミノキシジル配合育毛剤の着色防止方法。さらに、実質的にポリエチレンテレフタレート製プラスチックで構成される、ミノキシジル配合育毛剤が充填された容器。【選択図】なし
