The flow patterns in a Searle gap of two dilute aqueous cationic surfactant solutions, tetradecyl trimethyl ammonium salicylate (TTASal) and hexadecyl trimethyl ammonium salicylate (HTASal), have been investigated by means of a light sheet visualization. With this technique the structures visualized in the test liquids can be studied without tracer. The results of the light sheet visualization of the TTASal and HTASal solution show that in spite of the similarity of the surfactant systems the shape and evolution of the structures are significantly different.
