Abstract

Procedure for producing microcapsules having strong cell walls, characterized in that it comprises the steps of emulsifying an oil, which has to be microencapsulated, which contains a first capsule wall-forming substance and a second capsule wall-forming substance, which forms a high molecular value compound, reacting with the first capsule wall-forming substance in a polar liquid, which is a continuous phase, and forming the microcapsules by reacting the first wall-forming substance with a third capsule wall-forming substance in a polar liquid, on the surface of the oil droplets, in the same reaction system, in which the capsule walls are formed by the reaction of the first capsule wall-forming substance with the second capsule wall-forming substance in the inside the oil droplets, so a stable, low permeability capsule wall is obtained for encapsulated contents.
