Salt‐Induced Modulation of Self‐Assembly in C8‐10 AlkylPolyGlucoside/Fatty Alcohol Formulations

A formulation strategy based on the alkyl polyglucoside (APG) surfactant Triton CG‐110, in combination with 1‐Dodecanol as a co‐surfactant and brine as an additive, is developed. The results highlight the pivotal role of brine in modulating the rheological properties of the system, inducing a shift from viscous to viscoelastic and yield‐pseudoplastic behavior at elevated surfactant and salt concentrations. Small‐angle X‐ray scattering analysis reveals that increased salinity enhances interparticle correlations within bicellar nanostructures, which are closely associated with improved viscoelasticity and formulation stability. The salting‐out effect, combined with the ability to incorporate 1‐Dodecanol, leads to nanoscale structural transitions that provide a rational basis for tuning the performance of surfactant systems. The resulting high oil‐uptake efficiency of 82% in the final formulation demonstrates a viable pathway toward high‐efficiency, environmentally benign surfactants, supporting the broader transition to greener chemistries in industrial applications.
