The Gibbs-Duhem equation of an ionic aggregate is obtained, considering the activity coefficient of the aggregate due to the interaction between the aggregate ion and its diffusion layer. The equation is applied to mixtures of cationic and nonionic surfactants. The critical micelle concentrations of

The aggregation behavior of Synperonic A7 and A50, fatty alcohol ethoxylate nonionic surfactants (C(m)E(n)) with mean polyoxyethylene chain lengths of 7 and 50, respectively, was investigated in aqueous solution by means of surface tension, laser light scattering, steady-state fluorescence, and fluo
The aggregation behavior, critical micelle concentration (cmc) and micelle aggregation number (N), of dodecyl maltoside (DM), octyl glucoside (OG), and Hecameg has been investigated in water and in water plus one of the three water-soluble polymers, polyoxyethylene (POE), polyoxypropylene (POP), and
## Abstract Although conformational analysis by NMR of ethylene glycol indicates generally strong preferences for the __gauche__ conformation in solvents ranging from water to chloroform, the bulk of the NMR evidence indicates that intramolecular hydrogen bonding between the hydroxyl groups is unli
