Abstract
A method for manufacturing microcapsules containing an active substance, the method including: providing an aqueous solution of a surfactant, an oily phase comprising the active substance and a first monomer, and a polar phase comprising a second monomer; preparing an oil-in-water emulsion by adding the oily phase to the aqueous solution of the surfactant; adding the polar phase to the oil-in-water emulsion, in order to obtain a polymer in a reaction mixture, by polymerization of the first monomer and the second monomer; isolating the microcapsules, including a wall formed by the polymer and containing the active substance, from the reaction mixture; wherein the polymer is a poly(beta-amino ester). Microcapsules obtained by the method.
