QUANTIFICATION OF RESIDUAL PERFUME BY PY-GC-MS IN FRAGRANCE ENCAPSULATE POLYMERIC MATERIALS INTENDED FOR BIODEGRADATION TESTS

Perfume encapsulates are widely used in commercial products to control the kinetic release of odorant molecules, increase storage QUIET FRIZZ CONDITIONER stability and/or improve deposition on different substrates.In most of the cases, they consist of core-shell polymeric microcapsules that contain fragrance molecules.A current challenge is to desi
