Abstract (en)
[origin: FR2774389A1] The invention concerns water dispersible granulates comprising: at least a hydrophobic perfume (P), in the form of droplets, finely divided in and encapsulated by a water soluble or water dispersible solid organic matrix (MO) selected among: polypeptides (PP) of plant or synthetic origin; polyelectrolytes (PE) belonging to the family of weak polyacids; or their mixtures; and at least an emulsifying agent (AE) at the droplet/matrix interface. The invention also concerns a method, in two steps, for preparing said granulates, the first step consisting in preparing an emulsion in water comprising at least a hydrophobic perfume (P), at least an emulsifying agent (AE); and said water soluble or water dispersible organic matrix (MO), the second step consisting in drying said emulsion until a granulate is formed.
