Temperature and flow stability of model sodium alkylbenzene sulfonate (NaLAS) micellar solutions

Abstract: Linear sodium alkylbenzene sulfonate (NaLAS) is one of the most extensively used anionic surfactant in the world, mainly as a biodegradable laundry detergent, with an annual production of several billions of kg. During storage and utilisation, NaLAS micellar solutions undergo temperature fluctuations and are exposed to flow fields, which affect both the thermodynamic stability and performance of NaLAS `formulations'. Certain additives, including propanediol (pdiol) can non-trivially affect the phase behaviour and thus the stability of these formulations but their role, as solvents, co-surfactants or additives, remains elusive at the molecular level. Building on extensive microscopy, SAXS and preliminary SANS data, this proposal seeks to investigate the role of cooling rate and flow on the assembly and phase transformations in NaLAS solutions.
