abstract = {HypothesisThe rational design of branched-tail surfactants
is a suitable strategy to obtain low-viscosity
surfactant-rich isotropic aqueous mixtures with negligible
effects on biodegradability. This opens a way to the design
of concentrated (“water-free”) surfactant formulations,
highly attractive for their ecological and economic
benefits.ExperimentsThe aggregation behaviour of
N,N-dimethyl-2-propylheptan-1-amine oxide (C10DAO-branched)
in aqueous mixtures is investigated across the entire
composition range by polarized optical microscopy, small
angle X-ray and neutron scattering, electron paramagnetic
resonance, and pulse-gradient stimulated echo nuclear
magnetic resonance. The humidity scanning quartz crystal
microbalance with dissipation monitoring technique is
validated as a tool for the fast screening of surfactants
phase behaviour. Furthermore, the shear viscosities and
viscoelastic moduli of the systems are determined by
rheological measurements.FindingsWith respect to the linear
isomer, C10DAO-branched presents a much lower tendency to
form lyotropic liquid crystalline phases. Except for a
narrow composition and temperature range in which a lamellar
structure is observed, C10DAO-branched aqueous mixtures are
isotropic liquids whose microstructure changes, with
increasing concentration, from micellar solutions to
unstructured dispersions of hydrated surfactant molecules.
Low-viscosity was found for all these mixtures, including
the most concentrated ones. Thus, the introduction of a
single short side-chain in the tail is demonstrated to be an
effective approach to increase the active concentration in
surfactant formulations.},
