Comparative analysis of liquid crystal properties of lyotropic lanthanum-containing system based on nonionic surfactants with different number of oxyethylated groups was made by polarizing optical microscopy. Structural characteristics of lyotropic mesogens with different supramolecular organization in the mesophase: lamellar and hexagonal were assessed based on the data of X-Ray diffraction. It is shown that the type of mesomorphism will be determined by the structure of the hydrophilic part of the surfactant molecules.
