“…The profiles for SDS, SDDS, and PEG8-L have a well-shaped sigmoid, as already reported in the literature. 28 , 33 On the contrary, two or more inflections in the decrease of I/III pyrene fluorescence emission are recognized for the polyethylenglicol ester surfactant PEG8-S 34 , 35 and bile salts (as NaDC). 23 These inflections are particularly evident for NaDC, reflecting the stepwise aggregation behavior of this amphiphile.…”

Critical micelle concentration (CMC) is the main chemical–physical parameter to be determined for pure surfactants for their characterization in terms of surface activity and self-assembled aggregation. The CMC values can be calculated from different techniques ( e.g ., tensiometry, conductivity, fluorescence spectroscopy), able to follow the variation of a physical property with surfactant concentrations. Different mathematical approaches have been applied for the determination of CMC values from the raw experimental data. Most of them are independent of the operator, despite not all of the fitting procedures employed so far can be applied in all techniques. In this experimental work, the second derivative of the experimental data has been proposed as a unique approach to determine the CMC values from different techniques (tensiometry, conductimetry, densimetry, spectrofluorimetry, and high-resolution ultrasound spectroscopy). To this end, the CMC values of five different surfactants, specifically three anionic (sodium dodecyl sulfate, sodium deoxycolate, and N -lauroyl sarcosinate) and two nonionic, such as polyethylene glycol ester surfactants [polyethylenglicol (8) monostearate and polyethylenglicol (8) monolaurate], have been determined by this approach. The “second-derivate” approach provides a reliable determination of the CMC values among all of the techniques investigated, which were comparable to those calculated by the other operator-free routinely methods employed, such as segmental linear regression or Boltzmann regression. This study also highlighted the strengths and shortcomings of each technique over the others, providing an overview of the CMC values of commonly used anionic and nonionic surfactants in the pharmaceutical field, determined by employing different experimental approaches.

“…This also implies the mixed micelles were formed in the system (Blagojević et al, 2016). This negative deviation originated from the enhancement in hydrophobicity of a mixed system due to two factors: (1) intercalation of BGF‐10 into the micelles of HCQAS 3a shielded the repulsive interactions between charged head groups and improved the electrostatic stabilization of the mixed micelles and (2) attractive ion–dipole interaction between headgroups of ionic and nonionic components (Nandni and Mahajan, 2013). As a result, the CMC and γ CMC independently synergized 20.59% and 1.97% when the molar ratio of 3a was 0.2, and enhanced 12.11% and 4.83% at the ratio of 0.4.…”

“…This inspires us to look for another type of surfactant that is also green and renewable in combination with BGF-10 to replace the use of TX-10 in detergent. The mixture of these surfactants hopefully results in interesting properties that will reduce the cost and the environmental pollution (Nandni and Mahajan, 2013). This has great reality and industrial significance.…”

A series of novel hydroxylated cardanol quaternary ammonium salts (HCQAS 3a-3g) with one or two hydroxyl groups, derived from renewable cardanol, a plantbased and low-cost material natural cashew nut shell liquid (CNSL), have been rationally designed and investigated as additive in detergent. CMC, γ CMC , C 20 , pC 20 , and CMC/ C 20 were employed to exhibit the surface properties of HCQAS, reflecting that the surfactivity were superior to general cationic surfactants. In addition, HCQAS revealed excellent water solubility and wettability by krafft point and contact angle tests. Moreover, emulsifiability and foamability conversions were monitored versus time and volume of foam, respectively. Also, TEM micrographs were taken to provide the aggregation morphologies of HCQAS 3a aqueous solution at different concentration. Furthermore, HCQAS 3a and BGF-10 binary composite system as well as HCQAS 3a, BGF-10, and SDBS ternary composite system were investigated by CMC, γ CMC , emulsifiability, and foamability to determine the optimum molar ratio (HCQAS 3a: BGF-10: SDBS = 0.24:0.36:0.4), and then, analysis of morphology by TEM showed that the incorporation of HCQAS 3a, BGF-10, and SDBS in aqueous solution accelerated the formation of abundant vesicles with large volume and surface area. Finally, a green concentrated detergent was designed and prepared with the filtered ratio, where the presence of vesicles greatly enhanced detergency to promisingly replace the familiar use of petroleum-based TX-10 in detergent. This study on the structure and performance of HCQAS may shed some light on the development of novel environmentally friendly surfactant.

“…The excess free energy of micellization (∆ G ex ) is an important indication to gauge the nonideal behavior of the mixed systems (Azum, Asiri, Rub, & Al‐Youbi, ; Azum, Rub, & Asiri, ; Chauhan et al, ; Kumar & Rub, ; Nandni & Mahajan, ; Rub, Khan, Sheikh, Azum, & Asiri, ). The ∆ G ex values were obtained by considering the different employed models (Rubingh’s [∆ G ex Rub ], Motomura’s [∆ G ex M ], and Rodenas’s [∆ G ex Rod ]).…”

Surfactant mixtures are used in many different industrial formulations. In this study, the mixed micelle formation behavior of 2 different cationic surfactants, namely dodecyltrimethylammonium bromide (DTAB) and benzyldimethylhexadecylammonium chloride (BDHAC), in the absence and presence of urea at various temperatures (298.15–318.15 K) was studied using the conductometric method. The attractive interaction between DTAB and BDHAC was estimated from the values of critical micelle concentration (CMC) and the CMC for ideal mixing (CMCid). Urea increases the CMC value as a result of the enrichment in the surface charge of the micelles/mixed micelles. The values of micellar mole fraction (X1Rub [Rubingh], X1M [Motomura], X1Rod [Rodenas]) and ideal micellar (X1id) of surfactant BDHAC were obtained by different models and are shown to exhibit the high contribution or effective involvement of BDHAC in mixed micelles and increase with increasing BDHAC mole fraction (α1). Activity coefficients (f1 and f2) were also evaluated from the relevant formula given in the literature. The negative values of the interaction parameters (β) show the attractive interaction among the studied components. Excess Gibbs free energy (∆Gex) of micellization revealed that the stability of mixed micelles is higher in aqueous solution than in urea solution. The thermodynamic parameters, namely the Gibbs free energy change, enthalpy change, and entropy change (∆Gom, ΔHom, and ∆Som, respectively), were also calculated from the conventional standard equations.
