Effect of type of fragrance compounds on their location in hexagonal liquid crystal

Kayali, Ibrahim ; Qamhieh, Khawla and Lindman, Björn LU (2006) In Journal of Dispersion Science and Technology 27(8). p.1151-1155
Abstract
Three fragrances, limonene, benzaldehyde, and phenethylalcohol (that differ in their polarities), were solubilized in hexagonal liquid crystal using the polyethylene oxide-polypropylene oxide-polyethylene oxide, (EO27 PO61 EO27), P-104 triblock copolymer, and water. The interlayer spacing of the hexagonal liquid crystals were established using small-angle x-ray scattering (SAXS). The SAXS data are used to calculate the interfacial area per polyethylene oxide (PEO) block and the radius of the apolar domain in order to determine the location of each fragrance in the association structure. The results show the presence of limonene inside the core of the apolar domain while benzaldehyde is only partially located inside the core with the other... (More)

The results show the presence of limonene inside the core of the apolar domain while benzaldehyde is only partially located inside the core with the other part contributing to the interface. The third fragrance, phenethylalcohol, is present between the polar heads, thus, contributing entirely to the interface. (Less)
