poliéster hiper-ramificado com núcleo hidrófobo para a solubilização de substâncias ativas de baixa solubilidade |
摘要 |
The present 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 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. |
