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 whose solubility in water at 20&#xb0; C. is not more than 10 g/L, and an amphiphile comprising an alkoxylated hyperbranched polycarbonate, wherein the polycarbonate comprises an alcohol which is a trifunctional or higher polyfunctional polyetherol based on a C-Calkylene oxide and an alcohol which has at least three OH groups. Likewise provided is an amphiphile comprising the polycarbonate, and a process for preparing the amphiphile. The invention further relates to the use of the amphiphile for solubilizing an active ingredient whose solubility in water at 20&#xb0; C. is not more than 10 g/L, in aqueous solutions, and a method of controlling phytopathogenic fungi and/or unwanted plant growth and/or unwanted insect or mite infestation and/or of regulating the growth of plants.

Alkoxylated hyperbranched polycarbonates for solubilizing poorly soluble active ingredients

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

A process for solubilizing hydrophobic active ingredients in aqueous medium, which comprises using, as an assistant, at least one hyperbranched polymer (A) which is obtainable by reacting at least one hyperbranched polymeric compound having at least one primary or secondary amino group per molecule (a), selected from

Process for solubilizing hydrophobic active ingredients in aqueous medium

Described is a metal oxide support material containing nanoscaled iron-platinum group metal particles having a particle size in the range of 0.5 to 10 nm. At least 70% of the nanoscaled iron-platinum group metal particles are located on an outside surface layer of the metal oxide support material. The outside surface layer has an average volume of less than 50% based on the total volume of the metal oxide support material. Additionally, described is a process for preparation of metal oxide support materials containing nanoscaled iron-platinum group metal particles. Furthermore, described is the use of metal oxides containing nanoscaled iron-platinum group metal particles as catalysts, for example as a diesel oxidation catalyst for the treatment of exhaust gas emissions from a diesel engine.
