Prediction of micellar molecular weights and thermodynamics of micellization of mixtures of alkyltrimethylammonium salts

Study of mixtures of n-dodecyl-β-d-maltoside with anionic, cationic, and nonionic surfactant in aqueous solutions using surface tension and fluorescence techniques

“…The weaker interaction in cationic/nonionic system is attributed to the fact that nitrogen atom in the hydrophilic group of dodecyltrimethylammonium bromide is screened by three methyl groups that hinder formation of ion-dipole interaction [33]. The small residual charge of a dodecyltrimethylammonium bromide micelle (0.23-0.36 [34][35][36]) supports this suggestion.…”

The sphere-rod transition of micelles of dodecyldimethylammonium bromide in aqueous NaBr solutions, and the effects of counterion binding on the micelle size, shape and structure

“…Such a linear relation was proposed by Barry and Russel [27] for spherical micelles of some cationics, to limited extents.…”

The Temperature Dependence of the Critical Micelle Concentrations of Foam-Forming Surfactants

“…At the same time, the degree of water holtz equation. The contributions from formulation components may in fact be small, as shown by a thermodynamic structuring (''icebergs'') diminishes, and at about 160ЊC the ''icebergs'' have vanished and the enthalpy becomes analysis of a commercial surfactant mixture (55).…”

“…The variation of CMC with temperature for the ionic surand amphoteric surfactants where the free energy of micellization was reported between 023 and 042 kJrmol 01 at 25ЊC factants in a 0.399 mol/kg ionic strength solution at 1.38 MPa (applied) was given by (18,49,55,59,60). The values in Table 2 ÉT red 0 1É 5.80 .…”

“…The mass-action model assumes that an equilibrium exists between the monomeric surfactant and the micelles. The phase separation model, used here, assumes that the aggregate with its counterions in the surrounding atmosphere is a separate phase (55). The thermodynamics is that of the solubility of ordinary solutes (56),…”
