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… More >
