Patent ID: 7589144

Claim:
A granule made by the process of drying an inverse emulsion, dispersed in an external aqueous phase, wherein: (a) the inverse emulsion comprises an internal aqueous phase comprising at least one hydrophilic active substance, dispersed in an internal organic phase, said inverse emulsion comprising at least one nonionic surfactant, at least one amphiphilic block polymer, or at least one cationic surfactant; and (b) the external aqueous phase comprises: at least one polyalkoxylated nonionic surfactant or at least one polyalkoxylated amphiphilic nonionic polymer, and at least one water-soluble or water-dispersible polymer, wherein said at least one water-soluble or water-dispersible polymer: is a solid in the presence of a water content of at most 10% by weight relative to the weight of said at least one water-soluble or water-dispersible polymer, and has a glass transition temperature of greater than 25° C.
