title: Double-chain cationic surfactant and n-pentanol: an L3 phase in the rich-water domain?
abstract: A ternary system containing water, pentanol and a quaternary cationic surfactant, dioctadecyldimethylammonium bromide (DODAB) was investigated. We present the phase diagram and ESR studies that demonstrate the existence of the well-known L3 or sponge phase in the water-rich domain of the diagram. The remarkable fact is the existence of some kind of order in such diluted conditions.
