Abstract
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 prepang 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.
