Process for preparing microcapsules having a polyurea shell and a lipophilic core material
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 l...
