abstract = {HypothesisThe self-assembly of long-tail surfactants
results in the formation of nanoscale structures, e.g.
worm-like micelles, with the ability to modify the rheology
of the system. However, micelle formation, and thus the
alteration of the rheology, is subject to the high Krafft
temperature of saturated long-tail surfactants.
Hexadecylmaltosides are sustainable surfactants that, in
solution, form tailorable viscoelastic fluids. The
preparation of monounsaturated sugar-based surfactants is
hypothesised to reduce the Krafft point compared to the
saturated analogues, therefore increasing the temperature
range where the surfactant remains in the micellar
form.ExperimentsHere we report the synthesis and
characterisation of a novel sugar-based surfactant with an
unsaturated C16-tail, namely palmitoleyl-β-d-maltoside
(β-C16-1G2). Differential scanning calorimetry was used to
probe the temperature stability of the system. The rheology
of β-C16-1G2 solutions was investigated by means of
rotational and oscillatory rheology, and these results were
connected to the mesoscopic structure of the system as shown
by small-angle neutron and X-ray scattering, and dynamic
light scattering.FindingsThe presence of a double bond on
the alkyl chain moiety leads to a depression in the Krafft
point, allowing the surfactant to form a thermodynamically
stable micellar solution over a wide range of temperatures,
i.e. 5–95 °C. The surfactant self-assembles into
worm-like micelles which, upon entanglement in the
semi-dilute regime, result in the formation of a
non-Newtonian, viscoelastic fluid. These observations have
important implications in the development of new sustainable
formulated products, enabling the preparation of surfactant
phases with remarkable thermal resilience.},
