    摘要: Water-redispersible granules including at least one active material in the form of a hydrophobic liquid, at least one non-ionic surfactant selected from polyoxyalkylene derivatives, and at least one water-soluble compound selected from polyelectrolytes belonging to the weak polyacid family are disclosed. A method for preparing such granules by preparing an aqueous emulsion of at least one active material, at least one non-ionic surfactant and at least one water-soluble compound, and drying the resulting emulsion, is also disclosed.

    摘要: The invention relates to a method for preparing monodispersed biodegradable microspheres consisting in a) preparing an emulsion containing at least one polymeric phase and at least one aqueous phase at a viscosity ratio between the dispersed polymeric phase and the aqueous phase ranging from 0.12 to 10, b) exposing the thus obtained emulsion to a controlled laminar shear strength, c) removing a solvent from the polymeric phase and in d) isolating the thus obtained microspheres. The use of the prepared microspheres is also disclosed.
