IMPROVEMENTS IN OR RELATING TO ENCAPSULATED PERFUME COMPOSITIONS

摘要

Disclosed are perfume compositions containing perfume ingredients selected on the basis that they are able to be stably incorporated into core-shell microcapsules. Perfume selection rules are based on a molecular descriptor of the electron density distribution within a perfume ingredient – RECON VOLTAE. Perfume ingredients having known RECON_VOLTAE values larger than about 1200 Bohr3, more particularly larger than 1540 Bohr3, and more particularly still larger than about 1750 Bohr3 are particularly suitable for encapsulation.
