Abstract
A process for preparing nanocapsules with a liquid lipid core and a solid lipid shell, charged with at least one active agent. The process contains at least the steps of formulating a microemulsion by phase inversion of an emulsion, totally or partially forming from at least one active agent a second composition different than the microemulsion, placing the microemulsion in contact with the second composition under conditions suitable for interaction of the active agent with the microemulsion, and chill-hardening the microemulsion that has interacted with the active agent, to obtain the nanocapsules.
