The structural types of aqueous systems of surface-active substances and their X-ray diffraction characteristics

In recent years many papers have dealt with X-ray diffraction by aqueous systems of detergents and colloidal electrolytes. The results have clearly indicated the existence of several different types of fine structure due to different colloidal particles, even in the phases belonging to a single surface-active substance. It is opportune to summarize this information to serve as a basis for further work. A classification of such structures is here suggested.
