Abstract
Provided is an aqueous composition contained in a container, maintaining an excellent water-evaporation-inhibiting effect even when an alkali metal salt or the like is contained in the aqueous composition, and having excellent long-term stability. The aqueous composition contained in a container includes the following components (A) to (D): (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, (C) a nonionic surfactant having an ethylene oxide group (but excluding component (A)), and (D) water.

A method of inhibiting water evaporation of an aqueous composition, comprising:
- incorporating, into an aqueous composition,
- (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;
- (C) a nonionic surfactant having an ethylene oxide group (but excluding component (A));
- (D) water;
- and
- (E) at least one member selected from the group consisting of a metal of Group 1 in the periodic table, a metal of Group 2 in the periodic table, and a water-soluble compound of these metals,
- wherein a content mass ratio of component (C) to component (E) is from 1:20 to 50:1.
