We studied the temperature and concentration dependence of the POPC/C_{12}EO_{2}/water ternary system and identified and characterized the different phases occurring. The thermal behaviour is slightly dependent on the surfactant to lipid molar ratio R_{s/l}. At low surfactant content the behaviour is similar to the binary lipid/water system. Similarly at low lipid contents the system behaves similarly to the surfactant/water mixture. However, at molar ratios R_{s/l} between 2 and 3 a new hexagonal phase forms which is peculiar to the mixture. ^{2}H NMR measurements indicated the existence of a lamellar phase containing also curved surfaces additional to the flat ones. The surface area per surfactant molecule was calculated to 0.23 nm^{2} which is in good agreement with the cross-section of a paraffinic chain.
