Abstract:
The aqueous solutions of sodium cumene sulphonate (NaCS) and its mixtures with each of cetyl trimethylammonium bromide (CTAB)
and sodium dodecyl sulphate (SDS) are characterized by small angle neutron scattering (SANS). NaCS when added to CTAB solution
leads to the formation of long rod-shaped micelles with a dramatic increase in the CTAB aggregation number. Its addition to
SDS on the other hand results in the formation of smaller mixed micelles where part of SDS molecules in the micelle is replaced
by NaCS molecules.
