abstract = {The phase diagram of the ternary aqueous system composed by
two polydisperse ethoxylated surfactants, commercially known
as 24-3 and 24-7, with the average molecular formula
corresponding to triethylene – and heptaethylene –
glycol dodecyl ether, has been developed at 25 °C. The
identification of the different lyotropic liquid crystalline
(LLC) structures, whose range of stability has been
preliminarily determined by visual inspection through
cross-polarizers, has been performed using polarized optical
microscopy (POM), small angle neutron and X-ray scattering
(SANS, SAXS). Data have been analyzed in terms of the
combined effects of the different length of
poly(oxyethylene) chains of the two surfactants and
hydration/dehydration of the polar headgroups, depending on
the total surfactant concentration. Peculiar effects of both
hydrophobic and hydrophilic chains polydispersity have been
highlighted. Our results shed light on the aggregative
behavior of surfactant mixtures widely used in homecare
detergent formulations.},
