Abstract

The structural properties of nonionic surfactant Brij 35 in water and alcohol were investigated using small-angle X-ray scattering (SAXS) and dynamic light scattering (DLS) technique. At low surfactant concentrations the micelles were more or less spherical, whereas slight elongation of the micelles was observed at concentrations above 10 mass %. SAXS spectra of Brij 35/alcohol binary systems showed strong alcohol peaks at higher values of the scattering vector q. The results indicated that the transformation of the large objects into smaller structures that resembled the smaller population found in binary systems.
