“…This necessitates the development of a new generation of cationic surfactants having a high surface activity, excellent adsorptive ability, and antibacterial activity. It has been reported that the properties of surfactants can be improved by rationally tuning their molecular structure (Akbaş et al, ; Ding et al, ; Haldar et al, ).…”

The cationic surfactants containing aromatic rings and amide bonds, N,N-dimethyl-N-dodecyl-2-pyrimidinylcarbamoylmethyl ammonium chloride (a), N,N-dimethyl-N-dodecyl-2-thiazolylcarbamoylmethyl ammonium chloride (b), and N,N-dimethyl-N-dodecylphenylcarbamoylmethyl ammonium chloride (c), were synthesized and characterized. The surface tension and conductivity values were employed to investigate the absorption and micellization behavior of the three cationic surfactants. The results showed that the synthesized surfactants have shown a low critical micelle concentration (CMC) and a high adsorption efficiency (pC 20 ) compared with the traditional cationic surfactant of N,N-dimethyl-Ndodecyl-N-benzyl ammonium chloride (BAC-12). The aromatic rings of the a, b, and c molecular structures were analyzed using the 1 H NMR spectra for electrostatic repulsion effects between hydrophilic headgroups. The size distribution of the micelles was derived using dynamic light scattering (DLS) techniques. In addition, the foaming ability of a, b, c, and BAC-12 was investigated and the antimicrobial activity of a, b, c, and BAC-12 against Escherichia coli, Staphylococcus aureus, and Bacillus subtilis was examined. The effects of amide bonds and aromatic rings on the surface properties and antimicrobial activity of a, b, and c were analyzed and compared with BAC-12 of the same alkyl chain length. The synthesized surfactants exhibited a high surface ability and better antibacterial activity compared with BAC-12.

Four novel cationic gemini surfactants with the same hydrocarbon chain lengths but different spacers have been investigated in this article. After these cationic gemini surfactants have been synthesized, their structures have been characterized by appropriate spectroscopic methods. By determining their Krafft temperatures, the effects of spacer type and structure on Krafft temperature have been examined. Micellization behaviors of the cationic gemini surfactants have been researched at temperatures above the determined Krafft temperatures. Critical micelle concentration (cmc), counterion binding degree (β), and counterion dissociation degree (α) and standard enthalpy change (ΔH mic o ), standard Gibbs free energy change (ΔG mic o ), and standard entropy change (ΔS mic o ) of micellization of cationic gemini surfactants have been calculated. The solubilization capabilities of these surfactants have been evaluated according to the molar solubilization ratio (MSR). Additionally, the emulsification powers have been measured.

N,N′‐bis [3‐(dodecanoylamino)propyl]‐N,N,N′,N′‐tetramethylhexane‐1,6‐diaminium dibromide is a cationic Gemini surfactant including quaternary ammonium salt with amide groups. Critical micelle concentration (CMC) and some thermodynamic parameters of the cationic Gemini surfactant were investigated using surface tension and conductivity methods. Mixed micellization of binary mixtures of the cationic Gemini surfactant with a conventional surfactant cetyl trimethylammonium bromide (CTAB) was investigated using the conductometric method at five different temperatures ranging from 303.15 to 323.15 K. CMC, micellar ionization degree (αm), counterion binding constant (g1), interaction parameter (β), and activity coefficients (f1M and f2M) of mixed systems were found out from data of conductivity at different mole fractions for all studied temperatures. Additionally, the effects of some inorganic salts with different concentrations on the surface properties of cationic Gemini surfactant were examined by surface tension measurements. Some surface properties of the pure cationic Gemini surfactant and mixed salts systems were calculated using the data of surface tension.
