PROBLEM TO BE SOLVED: To provide an aqueous composition contained in a container: which is suppressed in evaporation of the moisture content and is thus suppressed in solidification or property changes of the contents, thereby achieving excellent stability over time and which is suppressed in drying of the contents adhering to the discharge hole, thereby preventing clogging even in cases where the container that holds the aqueous composition is a spray dispenser or a pump dispenser.SOLUTION: Disclosed is an aqueous composition contained in a container, which contains the following components (A), (B) and (C): (A) a polyoxyethylene alkyl or alkenyl ether that has an alkyl group or alkenyl group with 20-24 carbon atoms, while having an average mole number of added ethylene oxide of 1.5-4 (B) a water-soluble polymer and (C) water.COPYRIGHT: (C)2012,JPO&INPIT【課題】容器入り水系組成物の水分蒸散を抑制することで内容物の固化や性状変化を抑制し、経時安定性に優れ、スプレー式容器、ポンプ式容器に用いた際にでも、吐出口に付着した内容物の乾燥を抑制し、目詰まりを防止することができる容器入り水系組成物を提供する。【解決手段】次の成分(A)、(B)及び(C):(A)アルキル基又はアルケニル基の炭素数が20~24で、エチレンオキサイドの平均付加モル数が1.5~4であるポリオキシエチレンアルキル又はアルケニルエーテル、(B)水溶性高分子、及び(C)水を含有する容器入り水系組成物。【選択図】なし
