In article number 1606099 , Philipp Erni and co‐workers report a strategy to form composite coacervate/polyurea capsules for the encapsulation of low‐molecular‐weight payloads, such as volatile fragrance molecules. A polyurea layer in the capsule shell provides a diffusion barrier in harsh media, whereas the protein‐based coacervate component enhances adhesion on the targeted substrate.
