Abstract:
1. A granule made by the process of drying an inverse emulsion, dispersed in an external aqueous phase, wherein: (a) the inverse emulsion comprising 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, or at least one cationic surfactant, and (b) the external aqueous phase comprising: at least one polyalkoxylated nonionic surfactant or at least one polvalkoxylated amphiphilic nonionic polymer, and at least one water-soluble or water-dispersible polymer provided in a solid form in the presence of a water content of at most 10% by weight relative to the weight of said polymer and whose glass transition temperature is greater than 25° C., wherein the water-soluble or water-dispersible polymer present in the external aqueous phase is a polymer (i) obtained from the polymerization
