Evaluation of Performance of a Polymer‐Based Fixative ( FIXSCENT ) on the Controlled Release Kinetics and Longevity of Top and Heart Notes of Alcoholic Perfume

The development of high‐quality perfumes requires the longevity and release profile of their fragrance components, particularly the top and heart notes. There are several approaches employed to reduce the rate of evaporation of its volatile aromatic compounds; one of those is the use of effective delivery technologies to control the release and evaporation of the highly volatile aromatic components. The sustained release fragrance formulations are trade secrets of perfume manufacturers, and only a limited number of sustained release reagents are available in the market. However, the performance of such reagents on the sustained release kinetics of fragrance components remains underexplored. In the present study, the effect of varying concentrations of a modern fixative (FIXSCENT‐2%) on the evaporation and release patterns of top notes and heart notes of a model perfume formulation was studied. A series of perfume samples (20% w/w ) containing varying concentrations of FIXSCENT (0%, 5%, and 10% w/w ) was prepared, and the release of selected top notes and heart notes was monitored over 24 h using a combination of gas chromatography–mass spectrometry (GC–MS) and sensory evaluation techniques. The results indicated a sustained release pattern and a significant delay in the release of both top and heart notes upon addition of 5% FIXSCENT; however, exceeding its concentration from 5% to 10% showed lesser performance, which could be due to over‐network trapping of the perfume components. The addition of 5% fixative successfully prolonged the retention of top notes by 94.46%, while the heart notes experienced a delay in the release by 59.97%. On the other hand, the addition of 10% fixative showed a 47.50% increase in the retention of top notes and a 48.36% increase in the heart notes. These findings suggested that the controlled use of this fixative product, FIXSCENT, can effectively control the release and evaporation of volatile components in perfumes without affecting the smell intensity, and thereby can enhance their longevity, endurance, and user experience.
