Abstract: Water-redispersible granules prepared by drying a water-in-oil emulsion including at least one active material in the form of a hydrophobic liquid; at least one water-soluble compound capable of forming, during the drying process, a solid continuous film in which droplets of the hydrophobic active material are trapped; water; and at least one main surfactant with a binary water-surfactant phase diagram comprising an isotropic phase which is fluid at 25° C. up to a surfactant concentration of at least 50% by weight, followed at higher concentrations by a hexagonal, cubic or lamellar liquid crystal phase that is stable at least up to 65° C.
