Due to their amphiphilic properties, surfactant molecules in aqueous solution can form a large variety of different aggregates. This is related to the existence of many options to divide space into polar and apolar regions. The detailed chemical structure of the surfactant molecules determines the area of the polar group and the spontaneous curvature of the surfactant layer.
