PROBLEM TO BE SOLVED: To provide a simple method for stabilizing a component in a composition for external use.SOLUTION: A stabilization method for a component in a composition for external use includes adding an ion exchange resin to the composition for external use. The ion exchange resin is a cation exchange resin, and also the component to be stabilized is a compound which becomes unstable due to the presence of a compound selected from the group consisting of an amino group containing compound and an amine.COPYRIGHT: (C)2013,JPO&INPIT【課題】外用組成物中の成分を安定化させることができる簡単な方法を提供する。【解決手段】外用組成物にイオン交換樹脂を添加する、外用組成物中の成分の安定化方法。【選択図】図1
