A process for making hydrophobicized powders of micro- and/or nanocapsules
involving the steps of: (a) providing an aqueous polymer solution
containing at least one active ingredient and at least one hydrophilic
polymer; (b) providing an oil component heated to a temperature above a
gel point of the aqueous polymer solution; (c) dispersing (a) in (b) in
the presence of a water-in-oil emulsifier to form a dispersion; (d)
cooling the dispersion to a temperature below the gel point of the
aqueous polymer solution to form micro- and/or nanocapsules containing
the active ingredient encapsulated therein; (e) harvesting the micro-
and/or nanocapsules from the dispersion; and (f) contacting the micro-
and/or nanocapsules with an oil-absorbing auxiliary ingredient.
