  Provided is an aqueous composition contained in a container, where water evaporation of the aqueous composition contained in a container is inhibited, and thereby the contents are prevented from solidifying or changing in properties. As a result, excellent long-term stability is obtained, and even when the container is a spray container or a pump container, the contents adhering to the discharge opening of the container is inhibited from drying, and thereby clogging can be prevented. The aqueous composition contained in a container contains the following components (A), (B), and (C): (A) a polyoxyethylene alkyl or alkenyl ether having an alkyl or alkenyl group having 20 to 24 carbon atoms and an average molar number of ethylene oxide added of 1.5 to 4, (B) a water-soluble polymer, and (C) water.
