Dendritic polyurea for solubilizing active substances of low solubility
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, wherein the amphiphile comprises a dendritic polyurea which is joined to at least one linear or comb-type polymer, and the joining is effected via a difunctional linker, if the repeat units of the linear polymer are composed of polymerized alkylene oxide. The invention also relates to an amphiphile comprising a dendritic polyurea and a process for preparing the amphiphile.
