Title:
PROCESS FOR THE MANUFACTURE OF MICROCAPSULES AND MICROCAPSULES
Document Type and Number:
WIPO Patent Application WO/2024/089135
Kind Code:
A1
Abstract:
A continuous process for preparing microcapsules having an active ingredient encapsulated in a shell of cross-linked photopolymer which comprises providing a double emulsion comprising droplets of at least one active ingredient (C1) dispersed in a photopolymerizable composition C2, said droplets being dispersed in a composition C3, the compositions C2 and C3 being immiscible with each other; inducing a controlled shear rate in said double emulsion to provide a mixed double emulsion (C4); and irradiating the mixed double emulsion (C4) to prepare the microcapsules.
