Abstract:
The invention provides a composition comprising an active ingredient with a maximum solubility in water at 20° C. of 10 g/l, and a hyperbranched polyester based on a hydrophobic dicarboxylic acid and a trifunctional alcohol. The invention further relates to the hyperbranched polyester mentioned, to a process for preparation thereof and to the use thereof for solubilizing an active ingredient with a maximum solubility in water at 20° C. of 10 g/l in aqueous solutions.
