Abstract

The present invention provides a composition comprising an active ingredient whose solubility in water at 20° 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 C3-C12 alkylene 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° 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.
