Abstract

The present invention relates to the field of perfumery and in particular to a delivery system, in the form of nano-capsules, and a process for making nano-capsules containing a fragrance. Said delivery system comprises an external polymeric wall encapsulating a perfuming oil. The invention's delivery system is able to protect and release in a controlled manner the oil, so as to prolong over the time the perception of the fragrance of the latter. The invention concerns also the uses in perfumery of said delivery system.
