Abstract

The technical problem to be solved: (a) to increase stability of microcapsules having a core comprising a target lyophilic liquid with a low boiling point and which is immiscible with water, wherein said liquid is characterised in that it has the ability to hydrolyze and to form acidic products, said core being comprised in a spherical shell made of cured cross-linked polymeric material, which shell releases said target liquid when the surrounding environment has certain parameters leading to destruction of said shell; (b) to prevent the loss of the target liquid; and (c) to preserve microcapsule characteristics during long storage periods thereof. For this purpose the invention provides a method for producing microcapsules wherein a stabilising agent is added to the liquid to be encapsulated, which stabiliser suppresses the development of acidity during emulsification, coacervation and coalescence stages in a droplet of the liquid to be encapsulated and on the phase interface.
