Abstract

Abstract : Phase behavior containing alkyl ethoxysulfates (AES), ethanol, and H2 O over the whole concentration range was explored at 25°C. The system exhibited an isotropic solution phase (L), two different liquid crystalline phases: hexagonal phase (H), lamellar phase (Lα), and a biphasic region appearing with the ethanol concentration increasing. Polarized optical microscopy and small angle x-ray scattering were applied to characterize liquid crystalline phases. Direct two-phase titration and liquid chromatography–mass spectrometry (LC–MS) were employed to analyze the AES activity and homologues composition of the particles appearing in two-phase region.
