“…The cmc values (Table 1) of all the three gemini imidazolium surfactants, [C n Im‐3OH‐ImC n ]Br 2 (n = 12, 14, 16) were determined from the plots of absorbance (A) vs . surfactant concentrations (Alam et al, 2019) (as in Fig. 2b) and were found in confirmation with the values obtained from fluorescence measurements.…”

“…The determination of cmc from dye solubilization method is based on the observation that below cmc, there is low solubilization of dye and the amount of solubilized dye increases more linearly above cmc (Tehrani-bagha and Holmberg, 2013). The cmc values (Table 1) of all the three gemini imidazolium surfactants, [C n Im-3OH-ImC n ]Br 2 (n = 12, 14, 16) were determined from the plots of absorbance (A) vs. surfactant concentrations (Alam et al, 2019) (as in Fig. 2b) and were found in confirmation with the values obtained from fluorescence measurements.…”

The micellar, surface, and aggregation properties of biocompatible, imidazolium-based hydroxyl group-Br 2 , were studied. The surface parameters like maximum surface excess concentration at air/water interface (Γ max ), the minimum surface area occupied by surfactant molecules (A min ) and the related thermodynamic parameters such as, standard Gibbs free energy of micellization (ΔG 0 m ), standard free energy of adsorption (ΔG 0 ad ), and free energy of surface at equilibrium ðG s min ) were also determined from the surface parameters. The aggregation behavior has been elucidated from transmission electron microscopy (TEM) and dynamic light scattering (DLS) techniques which showed that these gemini surfactants have potential self-aggregation efficiency. Besides, some other physicochemical properties like foam stability, emulsifying power, and viscosity have been determined. The structural features of [C n Im-3OH-ImC n ]Br 2 enhance their surface-active properties. These features of gemini surfactants are of primary significance from pharmaceutical and biomedical viewpoints. The gemini surfactants may have great implications in drug formulations and delivery owing to their prominent aggregation and non-cytotoxic nature.

“…Surfactants (surface active agents) are compounds that contain both hydrophilic and hydrophobic parts in their chemical structure. 1 The main purpose of using surfactants for oileld applications is to decrease interfacial tension (IFT) between brine and crude oil, to promote wettability alteration of oileld rocks, to improve oil mobilization, and to help to form an oil bank. 2 Surfactants are continuously applied in a range of oil-eld applications including water shutoff, well completion, workovers, corrosion resistance, stimulation, drilling mud, rening, and enhanced oil recovery.…”

In this article, we report the salt effect on interaction of a water‐soluble polymer hydroxypropylmethyl cellulose (HPMC) with the cationic Gemini surfactant (ethane‐1, 2‐diyl bis(N,N‐dimethyl‐N‐hexadecylammoniumacetoxy) dichloride, 16‐E2‐16), and also its monomeric counterpart cetyltrimethylammonium chloride (CTAC) using the tensiometric method. Surface tension of the amphiphiles diminished in the presence of the polymer as well as salts; eventually, the polymer gets saturated with the surfactant and there is no further change of surface tension of the solution. Interaction between the polymer and surfactant starts at the critical aggregation concentration (CAC) that is stronger for 16‐E2‐16 than CTAC. CAC and critical micelle concentration (CMC) values of the surfactant‐polymer binary mixtures at various concentrations of the polymer were determined. CAC as well as CMC of 16‐E2‐16 are considerably lower than CTAC. The inorganic salts (KCl and KBr) have a considerable influence on the polymer–surfactant interaction.
