Micellar and Thermodynamic Properties of Sodium Dodecyl Sulfate in Binary Aqueous Solutions of Di-, Tri-, and Tetraethylene Glycols

Aggregation and adsorption properties of sodium dodecyl sulfate in water–acetamide mixtures

“…The aggregation number of SDS decreases with the addition of AA (Fig. 5), which is similar to the trend observed for N agg by the addition of nonaqueous solvent to water [2,9,10,12,18]. The value of N agg appears to reach an almost constant value equal to 13 ±2 when the AA amount becomes 30% (Fig.…”

“…These values of cmc are given in Table 1. Although dielectric constant of the water + AA medium was reported [17] to increase up to the addition of about 70% (≈0.4 mole fraction) AA, conductance of SDS solution of a particular concentration decreases with increase in the AA concentration similar to the case in other media containing water and nonaqueous solvents [2,6,[9][10][11][12][13][14]18,19].…”

“…With increase in AA content, β initially decreases and remains almost constant beyond 30% of AA. In media containing water + polar nonaqueous solvent it has been reported [2,[8][9][10][11][12]14,18,19,27] that β either decreases or remains almost constant with increase in the content of the nonaqueous component.…”

Phase behavior of the mixtures of poly(oxyethylene) (10) stearyl ether (Brij-76), 1-butanol, isooctane, and mixed polar solvents

“…Thermodynamics and micellar properties of SDS in aqueous solutions of di-, tri-, and tetraethylene glycols were determined by employing a mass action model using different techniques. Glycols were regarded as a cosolvent rather than a cosurfactant forming mixed micelles [38].…”

Effects of alcohols on micellization and on the reaction methyl 4‐nitrobenzenesulfonate + Br− in cetyltrimethylammonium bromide aqueous micellar solutions

“…There is currently a lot of interest in studying the aggregation of surfactants in nonaqueous polar solvents [1] and in mixed aqueous solutions [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Mixed alcohol-water systems have particularly been investigated, mainly because of their importance in the preparation of microemulsions [19] and because of the improvement of resolution in micellar electrokinetic capillary chromatography [20].…”
