This invention relates to microcapsules and processes of microencapsulation of water soluble or water dispersible compounds by reverse-phase microencapsulation, referred to agrochemicals but not as a limiting feature, and how to combine them with other oil soluble or oil dispersible compounds in suitable formulations for agriculture, in a industrially viable process that yields tiny microcapsules (<5-10 μm, preferably) and very homogeneous distribution of particle size, and overall good performance of the formulation. Further, multiple combinations of this reverse-phase microcapsules are disclosed, being specially notorious the combination with normal-phase microcapsules in order to create a Capsule Mixed Suspension (CX) where an outer oil—or alternatively water—phase contains microcapsules of two types: those with a core of water—and actives dissolved or dispersed therein—and those with a core of oil—and actives dissolved or dispersed therein—. Water Dispersable Granules (WDG) and Emulsion Concentrates (EC) and suspension concentrates (SC) combinations with the reverse phase microcapsules are also successfully performed, providing a novel concept of combinations of oil soluble with water soluble microencapsulated active ingredients. |
