The invention relates to compositions that contain A) one or more copolymers, said copolymers containing one or more structural units obtained from a) 19.9 to 75.9 wt. % glycerin, b) 0.1 to 30 wt. % at least one dicarboxylic acid, and c) 24 to 80 wt. % at least one monocarboxylic acid according to formula (I) R1—COOH (I), in which R1 is (C5-C29)-alkyl; (C7-C29)-alkenyl; phenyl; or naphthyl, and B) one or more solvents that are not miscible with water. The invention is characterized in that said compounds either do not contain water or contain water in a quantity less than or equal to 1.0 wt. % with respect to the total weight of the respective composition. The compositions are advantageously suitable for producing pesticide compositions for example.
