“…The executed values of cmc and cmc id for individual SDS and TTAB along with their mixture in the different medium are summarized in Tables 1 and 2 and Table S1 (Supporting Information). The attained experimental cmc at 303.15 K for discrete SDS herein was 8.23 mmol.kg −1 while that was 8.34 mmol.kg −1 in our previous work [19] again more than one cmc was also observed by our group [30] and herein our cmc lie between this two cmc values. On the other hand, cmc of for pure TTAB was 3.76 mmol.kg −1 , and our previous work by Amin et al reported the cmc value of pure TTAB of 3.70 mmol.kg −1 [25] whereas Hoque et al reported 3.68 mmol.kg −1 at the same condition.…”

“…With the growth of the micelles, the extent of bound counterions to the stern layer dwindles which directs us for the assessment of amount of micelle ionization ( g) using the ratio of slope after and before micellization exploiting the subsequent equation: g = S 2= S 1 where S 1 and S 2 explicate the slope before and after micellization accordingly. [28][29][30] The assessment of g values was carried out by means of another method by Buckingham et al , [44] Kale et al , [45] and also by Bandhopadhyay and Moulik. [46] The knowledge of micelle firmness and the shape conversion of micelle can be obtained from the assessed g values.…”

Herein, we employed the conductometric measurement technique for the estimation of the interaction between two oppositely charged surfactants (anionic, sodium dodecyl sulfate [SDS] and tetradecyltrimethylammonium bromide [TTAB]) in two chloride (NaCl/NH4Cl) salts in the range of temperatures from 298.15 to 318.15 K. The deviation of experimental critical micelle concentration (cmc) from the corresponding ideal values of cmc (cmcid), the values of interaction parameters (β), and activity coefficients (f1 and f2) of the components reveal the existence of the interaction amongst the investigated components. The attained cmc values for SDS/SDS + TTAB decline with the rise of temperature in H2O/electrolytes medium. The reduction of cmc in the presence of electrolytes reveals the facilitated micellization in the electrolyte medium. The assessed values of the micellar mole fraction of TTAB (X1) obtained from theoretical models signify the significant contribution of TTAB in SDS + TTAB mixed micellization. The estimated negative values of free energy ( ΔGmo) and excess free energy (ΔGex) of micellization reveal that micellization is spontaneous and mixed micelles are extra stable than distinct micelle, respectively. The enthalpy ( ΔHmo) and entropy ( ΔSmo) in addition transfer energies of micellization were also evaluated and explained thoroughly.

“…CMC is a specific concentration at which surfactant monomer molecules selfassemble into nanostructures called micelles. 24,28 CMC represents surfactant concentration at which nearly maximum adsorption occurs; hence, it is of great interest regarding the practical use of surfactants. 25,27 Physicochemical, transport, and thermodynamic properties of surfactants such as activity, enthalpy, surface tension, solubilization, equivalent conductivity, density, viscosity, osmotic pressure, and turbidity, among others, are important in understanding useful surfactant interactions and behavior in solution.…”

The search for alternative, biodegradable, and sustainable raw materials to replace finite petrochemicals is an area of great interest. Triglycerides obtained from oilseed crops are such potential raw materials. In this study, sesame oil was trans-esterified to sesame fatty methyl esters (SEFAMEs) that were used as precursors in the synthesis of sesame fatty methyl esters sulfonate (SEFAMESO) surfactant. SEFAME and SEFAMESO surfactants were characterized by high-performance liquid chromatography–mass spectrometry (HPLC-MS), 1H NMR, and Fourier transform infrared (FTIR) spectra. HPLC-MS, 1H NMR, and FTIR spectra indicated successful trans-esterification and conversion of SEFAMEs to SEFAMESO. Solution properties of the SEFAMESO surfactant including hydrophilic–lipophilic balance (HLB) value, Krafft point, foam-ability, critical micelle concentration (CMC), counterion degree of binding and thermodynamic parameters such as ΔG°mic, ΔH°mic, ΔS°mic, ΔH°mic,* and T C were evaluated. The CMC values of SEFAMESO at 298.15 K were relatively lower than that of the sodium dodecyl sulfate (SDS) standard, and these values decreased to a minimum at 303.15 K and then increased with an increase in temperature. ΔG°mic values were negative indicating a spontaneous micellization process. ΔH°mic and ΔS°mic values revealed that micellization was entropy-driven at low temperatures and both entropy- and enthalpy-driven at high temperatures. ΔH°mic,* values were negative suggesting formation of stable micelles. The evaluated properties revealed the potential application of the synthesized surfactant as a cleansing agent.

Chemical permeation enhancers (CPEs) represent a prevalent and safe strategy to enable non‐invasive drug delivery across skin‐like biological barriers such as the tympanic membrane (TM). While most existing CPEs interact strongly with the lipid bilayers in the stratum corneum to create defects as diffusion paths, their interactions with the delivery system, such as polymers forming a hydrogel, could compromise gelation, formulation stability, and drug diffusion. To overcome that challenge, we explore the differing interactions present with sodium dodecyl sulfate (SDS), an ionic surfactant and a common CPE, and methyl laurate (ML), a non‐ionic counterpart with a similar length alkyl chain. Notably, we show that the use of ML effectively decouples permeation enhancement from gelation, enabling sustained delivery across TMs to treat acute otitis media (AOM) that is not possible with the use of SDS. We reveal that ML and ciprofloxacin form a pseudo‐surfactant that significantly boosts transtympanic permeation. The middle ear ciprofloxacin concentration is increased by 70‐fold in vivo in a chinchilla AOM model, yielding superior efficacy and biocompatibility than the previous highest‐performing formulation. Beyond improved efficacy and biocompatibility, this single‐CPE formulation significantly accelerates its progression toward clinical deployment.This article is protected by copyright.
