A solvent composition contains a tetralin compound (a) represented by the formula (I) and a polyether compound (b) represented by the formula (II). The solvent composition is excellent in safety and almost odorless, having a high capability of dissolving various organic materials, and also excellent in affinity to various substrates. The solvent composition is suitably used for various applications including various kinds of paints, adhesives, coating materials, detergents, and the like. ##STR00001## wherein x is an integer of 0 to 4; y is an integer of 0 to 8; R.sub.1 and R.sub.2 each independently represent an alkyl or alkoxy group having 1 to 10 carbon atoms or an alkenyl or alkenyloxy group having 2 to 10 carbon atoms; these groups may be substituted by a halogen atom; and when a plurality of R.sub.1 or R.sub.2 exists, R.sub.1 and R.sub.2 each may be the same or different, ##STR00002## wherein m is 1 to 10; p is 0, 1, 2, or 3; Prop represents 1,2-propylene group; R.sub.3 and R.sub.4 each independently represent an alkyl group having 1 to 10 carbon atoms; and when m is 2 or more, a methyl substituent in the 1,2-propylene group represented by Prop may be randomly positioned.
