Solubilization and location of phenethylalcohol, benzaldehyde, and limonene in lamellar liquid crystal formed with block copolymer and water

Research output: Contribution to journalArticle

Abstract

Three fragrances, phenethylalcohol, benzaldehyde, and limonene (that differ in their polarity), were solubilized in lamellar liquid Crystal Using the polyethylene oxide-polypropylene oxide-polyethylene oxide, (EO27PO61EO27), P-104 triblock copolymer, and water. The interlayer spacing of the lamellar liquid crystal 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 to determine the location of each fragrance in the association structure. The results show the presence of phenethylalcohol at the interface while part of benzaldehyde contributing to the interface and the other part being located inside the polar/apolar domains. The third fragrance, limonene, did not participate in the formation of the interface and is located inside the apolar domain. (c) 2005 Elsevier Inc. All rights reserved.
