PROBLEM TO BE SOLVED: To provide an aqueous composition for on-Steroidal Anti-Inflammatory Drugs (NSAIDs) containing foaming formulation having the following features: containing a surfactant having low skin stimulation property having no at an applied part and having shape retention property upon foaming.SOLUTION: The present invention relates to an aqueous composition for NSAIDs containing foaming formulation containing polyoxyethylene hardening castor oil having 20 to 60 of average addition mole number in ethylene oxide and at least one kind of nonionic surfactant selected from a group consisting of polyoxyethylene sorbitan fatty acid esters having 12 to 18 of average addition mole number in ethylene oxide and 15 to 25 of average addition mole number in carbons in fatty acid. The aqueous composition has low skin stimulation property, no-stickiness at an applied part and shape retention property upon foaming due to the total concentration of the surfactant is 0.1 to 0.5 wt% of total weight of the composition.COPYRIGHT: (C)2015,JPO&INPIT【課題】界面活性剤を配合し、皮膚刺激性が低く、塗布部位でべたつかず、かつ、泡沫化させた際に保形性を有する、非ステロイド性抗炎症薬(Non-Steroidal Anti-Inflammatory Drugs:NSAIDs)含有泡沫化製剤用水性組成物を提供することである。【解決手段】エチレンオキサイドの平均付加モル数が20~60のポリオキシエチレン硬化ヒマシ油およびエチレンオキサイドの平均付加モル数が15~25かつ脂肪酸の炭素数が12~18のポリオキシエチレンソルビタン脂肪酸エステルからなる群より選ばれた少なくとも1種の非イオン性界面活性剤を配合し、かつ、当該界面活性剤の濃度の合計が組成物全量に対して0.1~0.5重量%とすることで、皮膚刺激性が低く、塗布部位でべたつかず、かつ、泡沫化させた際に保形性を有する、NSAIDs含有泡沫化製剤用水性組成物に関するものである。【選択図】なし
