“…Basic data on surfactant-QUATS interactions is essential for understanding the effects of interplay of solutesolute, solute-solvent and solvent-solvent interactions on micelle formation [11][12][13][14][15]. Such information is useful to industrial chemists, especially in the optimization and determination of various characteristic properties of surfactants.…”

The self-aggregation of sodium dodecylsulphate (SDS), an anionic surfactant, in aqueous solutions of tetraalkylammonium bromide salts (R 4 NBr, where R = propyl, butyl and pentyl) was determined at various temperatures in the range 288.15-318.15 K. The critical micelle concentration (CMC) determined from conductivity data was used to study the thermodynamics of the surfactant. The presence of bromide salts was found to affect the micellization of SDS in accordance with the hydrophobicity of the tetraalkylammonium cations, thus the CMC values follow the order no additive [ Pr 4-NBr [ Bu 4 NBr [ Pen 4 NBr. The results from conventional conductivity methods were combined with those of spectroscopic techniques like fluorescence and UV-Vis studies.

“…As it is shown in Ref. [36], the presence of two cationic heads leads to an opposite behavior: as the perfluorinated chain length increases, a 0 increases at a significant level (13% per added CF 2 ). The large a 0 values obtained are attributed to strong ionic repulsions, but the effect of the chain length on a 0 is not discussed.…”
