Phase Behavior of Commercial AES/Ethanol/H sub(2)O Ternary System
Phase behavior containing alkyl ethoxysulfates (AES), ethanol, and H sub(2)O over the whole concentration range was explored at 25 degree C. The system exhibited an isotropic solution phase (L), two different liquid crystalline phases: hexagonal phase (H), lamellar phase (L alpha ), and a biphasic r...

Summary: | Phase behavior containing alkyl ethoxysulfates (AES), ethanol, and H sub(2)O over the whole concentration range was explored at 25 degree C. The system exhibited an isotropic solution phase (L), two different liquid crystalline phases: hexagonal phase (H), lamellar phase (L alpha ), 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. |
