Abstract

The present invention provides a composition comprising an amphiphile and an active ingredient whose solubility in water at 20° C. is not more than 10 g/L. Likewise provided is an amphiphile comprising a hyperbranched polycarbonate which is joined to at least one linear or comb-type polymer, a process for preparing the amphiphile, and the use of the amphiphile in compositions comprising an active ingredient whose solubility in water at 20° C. is not more than 10 g/L.
