ABSTRACT:
A stable molecular aggregate having an ordered structure comprising a surfactant containing a hydrophilic moiety and hydrophobic moiety and having in the hydrophobic moiety or between the hydrophobic moiety and the hydrophilic moiety a rigid moiety at least 10 .ANG. long is disclosed. The structure, unlike the spherical micelle formed by an ordinary surfactant in water or the loose lamellar micelle formed by a soap in a high concentration, is stable and durable in low concentrations, keeping a high degree of regularity. The structure has primarily a bilayer structure as a basic structural unit.
