    摘要: The invention relates to a method of making multilayer core/shell microcapsules for delivery of active agents such as fragrance components of perfume oils. The method includes forming an outer shell by coacervation surrounding an internal phase which contains the active agent; and forming an inner shell by interfacial polymerization at the interface between the internal phase and the outer shell. The internal phase contains the active agent. The microcapsules are typically incorporated in a consumer product wherein the multilayer shell prevents the active agent from release until desired, generally during use of the consumer product.

    摘要: The invention relates to a process for preparing a hybrid coacervate capsule by mixing a first polymer with particles to form particle/polymer complexes; interacting a second polymer with the particle/polymer complexes to form a mixture comprising hybrid complex coacervates which contain particulate inclusions; and adding a core material to the mixture so that the hybrid complex coacervates deposit as a coating layer around the core material. The capsules form another embodiment of the invention.
