“…The CMCs of gemini surfactants are usually two orders of magnitude smaller than those of the conventional unimers. In the present study, the CMCs of SDDC and SD are 0.750 and 74.5 mM [24], respectively. According to regular solution theory, the components with lower CMC will be enriched in the micelles in a mixed surfactant system [33].…”

“…Sodium decanote or sodium laurate was prepared by neutralizing decanoic acid or lauric acid with NaOH in ethanol; then the solvent was removed and sodium alkylcarboxylates were dried. Sodium didecaminocystine and sodium dilauraminocystine were synthesized based on the procedure previously reported [24]. The purity of all the surfactants was examined with NMR, and no surface tension minimum was found in the surface tension curve.…”

“…It is worthwhile to mention that the γ values can be accurately measured at lower concentrations near 0.01 mM. Generally, it is not easy to obtain such high γ values for gemini surfactant solutions using the Wilhelmy plate method 34,35 . By using the Gibbs adsorption equation Eq.…”

“…N-alkylamine surfactants derived from cystine and cysteine have been reported to form micelles and small lamellar vesicles in aqueous solutions [12]. Amide surfactants derived from cystine have been reported to show interesting surface properties and aggregation behaviour which allowed them to form various structures such as spherical vesicles [13]. However, there are only few reports on the synthesis and physicochemical properties of surfactants derived from methionine.…”

Amino acid based surfactants have been widely used as alternative to classical surfactants due to their interesting physicochemical properties, biological activities, biodegradability and low toxicity. The study of the physicochemical properties of surfactants such as critical micelle concentration (CMC) and Krafft temperature is an important aspect in determining their use in detergents or pharmaceutical compositions. In this study, a series of non-ionic and cationic surfactants with varying chain lengths (C8-C12), namely the O-alkyl esters of methionine and their hydrochloride derivatives respectively were synthesized and characterized by spectral data.In view of systematically studying the effect of the head group and chain length on the physicochemical properties, the critical micelle concentrations of both series were evaluated using conductivity measurements and pyrene fluorescence spectroscopy. The Krafft temperatures of selected synthesized methionine-based surfactants were also evaluated. The methionine surfactants were synthesized in good to moderate yield (54 -81%). For both ester and the hydrochloride series, the CMC of the surfactants were found to decrease with chain length, as commonly observed for all surfactants. The non-ionic O-alkyl esters of methionine displayed relatively lower CMC values compared to their ester hydrochloride derivatives for all the chain length studied. The ester hydrochloride derivatives showed an increase in the Krafft temperature with increasing chain length showing that the surfactants with longer chain length has a tendency to micellise at a much higher temperature.
