Abstract

"ENCAPSULATION PROCESS", characterized by encapsulating water-immiscible material within a polyurea shell comprising a surfactant, a protective colloid and an organic polyisocyanate; dispersing said immiscible phase in water in said aqueous phase to establish droplets of the water-immiscible phase in said aqueous phase; adjusting the pH of said aqueous phase to a value between 0 and 14; heating and maintaining the immiscible base in water and the dispersed aqueous phase on a temperature scale ranging from about 20º C to about 90º C, whereby said water-immiscible material is encapsulated within a polyurea capsular wrapper.
