Abstract:
The application describes a process for the preparation of microcapsules, wherein the microcapsules have a volume average diameter d of 15 to 90 μηη and a percentage of the shell weight of 3 to 40%, with reference to the total weight of capsules, wherein the shell of the microcapsules comprises at least one polyurea and the core comprises at least one lipophilic component, comprising the step of adding hydroxyalkylcellulose to a dispersion of polyurea microcapsules, microcapsules and their uses.
