Title:
【発明の名称】疎水性活性物質を含む水に分散性の顆粒
Document Type and Number:
Japanese Patent JP2002501816
Kind Code:
A
Abstract:
The invention concerns water dispersible granulates comprising at least a hydrophobic organic active substance (MA) solid or with melting point less than 100° C., in the form of particles, finely divided inside and encapsulated by a solid matrix and a water soluble or water dispersible polypeptide (PP) synthetic or of plant origin and at least an ionic or amphoteric dispersing agent (D) at the active substance/matrix interface. The invention also concerns the method for preparing said granulates in two steps, the first step consisting in preparing a dispersion in water comprising at least a hydrophobic active substance, at least an ionic or amphoteric dispersing agent (D) and at least a water soluble or water dispersible polypeptide (PP) synthetic or of plant origin, and the second step consisting in drying the dispersion until a granulate is formed.
