The aggregation morphology of 2 cationic surfactants (cetyldimethylethanolammonium bromide and cetyldiethylethanolammonium bromide), an anionic surfactant (sodium dodecylbenzenesulfonate), a nonionic surfactant (Triton X‐100), and 2 gemini surfactants (16‐4‐16,2Br−[butanediyi‐1,4‐bis(dimethyldohexylammonium bromide)] and 16‐6‐16,2Br−[hexanediyi‐1,6‐bis(dimethyldohexylammonium bromide)]) in the presence of the ionic liquid (IL) 1‐ethyl‐3‐methylimidazoliumbromide [Emim][Br] is studied using various techniques such as surface tension, conductivity, and UV–visible and fluorescence spectroscopy. Increasing the concentration of [Emim][Br] results in a decrease in the critical micelle concentration (CMC) value of the surfactants. Various interfacial properties, namely the surface excess concentration (Гmax), minimum area per molecule at the air–water interface (Amin), and surface pressure at the CMC (πcmc), as well as the thermodynamic parameters such as free energy of the given air/water interface (Gmins), Gibbs free energy of micelle formation (normalΔGm°), Gibbs free energy of micellization per alkyl tail (normalΔGnormalm,tail°), Gibbs energy of transfer (normalΔGtrans°), and standard free energy of adsorption (normalΔGads°) were also investigated. The aggregation number (Nagg) was determined by the fluorescence method. It was observed that Nagg decreased with increasing weight‐percent of the IL.

This study investigates the encapsulation and controlled release of perfume within micellar systems. We explored how perfume‐surfactant interactions and micelle structure influence fragrance delivery. Two mixed‐micelle systems, one with branched‐tail and the other with linear‐tail surfactants, were subjected to varying perfume concentrations, dilution, and time. Using small‐angle neutron scattering (SANS), gas chromatography‐mass spectrometry (GC‐MS), and statistical analysis, we determined that micelle size and shape are significantly affected by perfume content and dilution. While both systems exhibited similar trends, the branched‐tail system uniquely formed a lamellar phase at higher perfume levels. Our findings reveal a strong correlation between micelle geometry and headspace perfume concentration, highlighting the role of surfactant tail structure. This research provides fundamental insights into perfume‐micelle interactions, with potential applications in materials science and active ingredient delivery.

We report a novel methyl orange paired microextraction (MOP‐ME) and diffuse reflectance‐Fourier transform infrared (DRS‐FTIR) spectral monitoring for improved signal strength of total mixed cationic surfactants (CS+) for its quantification in real water samples. To the best of our knowledge, this is the first report that describes the rapid quantitative determination of total mixed CS+ using MOP‐ME/DRS‐FTIR. The method is based on separation and preconcentration of CS+ using chloroform as the extracting solvent by the formation of ion‐pair complex with anionic methyl orange (MO−) followed by DRS‐FTIR analysis. The intense vibration peak obtained at 2919 cm−1 in the FTIR spectra was used for the optimization of all analytical parameters and for the determination of mixed CS+. The best extraction efficiency of CS+ from the aqueous solution was obtained at pH 4.0 when extracted for 3 min in chloroform at a stirring rate of 250 rpm. The linearity range obtained for the determination of total mixed CS+ in water sample was 0.150–300 μg L−1 with the limit of detection and limit of quantification as 0.05 and 0.150 μg L−1, respectively. The good recovery percentage (97.1–109.5%) from wastewater showed that the method is very selective for the determination of total CS+ in complex sample matrices. The advantages of the MOP‐ME/DRS‐FTIR method are its simplicity, selectivity, and sensitivity toward the analysis of total mixed CS+ in wastewater samples.
