Claim:
1. A composition comprising an amphiphile and an active ingredient having a solubility in water at 20° C. of not more than 2 g/L, wherein the amphiphile comprises a dendritic polyurea which is joined to at least one linear polymer, and wherein the joining is effected by a difunctional linker, wherein the difunctional linker is selected from the group consisting of tolylene 2,4-diisocyanate, tolylene 2,6-diisocyanate, 2,4′-diphenylmethane diisocyanate, isophorone diisocyanate, and mixtures thereof, wherein the at least one linear polymer is a block polymer comprising polycaprolactone and polyethylene glycol, wherein the polyethylene glycol is connected to the difunctional linker via the polycaprolactone; wherein the active ingredient is a pesticide, wherein the molar mass M wherein the dendritic polyurea has a degree of branching per molecule of 10% to 90% and a weight-average molecular weight from 1,000 to 50,000 g/mol, and wherein the at least one linear polymer is a polyethylene glycol monomethyl ether-block-polycaprolactone polymer.
