The Physicochemical Basis of Perfume Performance in Consumer Products

Abstract

The literature on physicochemical aspects of perfume performance has been reviewed with emphasis on products for home and body care. Pertinent expressions related to perfume performance have been defined. For the first time a model study is presented to account for the dynamic aspects in applications of perfumed fabric softeners. A new headspace cell, which allows precise control of the atmospheric conditions and modelling of the dynamics of the drying process, has been designed. The determination of the deposition of selected fragrance chemicals and their evaporation, combined with olfactometric dose-response data, produced a reliable measurement of their performance in application.
