Abstract

Microencapsulation of neroline inside microcapsules having a polyurethane shell based on β-cyclodextrin (β-CD) and hexane diisocyanate was performed by interfacial polycondensation. The polyol nature of β-CD caused tight crosslinking of microcapsules wall. Microcapsules of neroline were characterized for their chemical composition and structure of the polyurethane shell by FTIR spectroscopy, thermogravimetric analysis, optical and electron microscopy, light scattering and electrophoresis measurements. Core content and encapsulation yield were 15% and 60%, respectively. Spherical microcapsules of mean diameter 29 μm were slightly cationic with an isoelectric point of 6.3. Neroline-loaded microcapsules were fixed on cotton fabric using an impregnation technique. The functionalized fabric showed improved resistance to washing cycles in comparison with previously reported diol-based microcapsules. Such microcapsules display great potential for the long-lasting release of fragrance in the framework of cosmetotextile.
