The invention provides a composition comprising an active ingredient with a maximum solubility in water at 20&#xb0; 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&#xb0; C. of 10 g/l in aqueous solutions.

Hyperbranched polyester with a hydrophobic nucleus for solubilizing poorly soluble active substances

The present invention provides a composition comprising an amphiphile and an active ingredient whose solubility in water at 20&#xb0; 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.

Dendritic polyurea for solubilizing active substances of low solubility

The present invention provides a composition comprising an active ingredient with a maximum solubility in water at 20&#xb0; C. of 10 g/l, and a hyperbranched polyester which is joined to a polar polymer which comprises a polycondensate or a polymer comprising ethylenically unsaturated monomers. The invention further relates to the hyperbranched polyester mentioned and to a process for preparation thereof. It further relates to the use of the hyperbranched polyester for solubilizing the active ingredient in aqueous compositions.

Hyperbranched polyester having a hydrophobic core for solubilizing active ingredients of low solubility

The present invention provides a composition comprising an amphiphile and an active ingredient whose solubility in water at 20&#xb0; 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&#xb0; C. is not more than 10 g/L.
