Patent ID: 10835885

Abstract:
The invention relates to a method for producing microcapsules, comprising the following steps: (a) providing a first aqueous preparation containing at least one prepolymer; (b) providing a second non-aqueous preparation containing the active substance to be encapsulated; (c) mixing the aqueous and the non-aqueous phases in the presence of at least one emulsifier and/or stabilizer in order to form an emulsion; (d) polymerizing the at least one prepolymer contained in the emulsion from step (c) in order to obtain a dispersion of microcapsules that enclose the active substance; (e) hardening and cross-linking the microcapsules obtained in step (d); and optionally (f) removing the microcapsules from the dispersion and drying the microcapsules, the method being characterized in that the emulsion is formed in the presence of at least one 1,2-diol in step (c).
