Abstract
Thermodynamic properties and aggregation behaviour of mixed micellar systems, comprised of sodium alkylcarboxylate salts, CnNa (where n = 8,10,12), ethoxylated alcohols, C4EOx (where EO = ethylene oxide group, X = 0,1,2,3,4), and n-alkyltrimethylammonium bromide salts, RNMe3Br (where R = octyl, decyl, and dodecy), have been studied to characterize the micellization process of the surfactants and to explore the specificity of interactions that lead to distinctive solubilization behaviour of polyethylene alkyl ether compounds in anionic and cationic micelles. The changes in the apparent molar properties of the surfactant in the monomer state, YSƒÓ,S, and in the micellar state, YMƒÓ,S; the distribution coefficient of the alcohol, KD between the micellar and aqueous phases; the change in the partial molar properties of the alcohol, ƒ¢ YMAS, and alcohol, NA
