Fluorescence of 8-Anilinonaphthalene-1-sulfonate and Properties of Sodium Dodecyl Sulfate Micelles in Water–Urea Mixtures

Gelatin–alpha olefin sulfonate interactions studied by dynamic light scattering

“…Binding of surfactants like sodium dodecyl sulfate to gelatin sols and gels have revealed anomalous relaxations, which has been studied in details in the past [26]. The coherent picture of polyelectrolyte-surfactant interactions that has emerged from this study is consistent with the universal polymer-surfactant complexation features described earlier by others [27,28]. It is worthwhile to subject the AOS-gelatin system to similar studies to explore the universality of these relaxations observed.…”

The Interaction of Micelles with Added Species and Its Similarity to the Denaturant Binding Model of Proteins

“…It seems therefore that urea participates in the solvation of non-polar species replacing some water molecules in their hydration shell, without altering the micellar structure or modifying the organization of water. This is in agreement with recent evidence (12) …”

Influence of additives on the clouding phenomenon of chlorpromazine hydrochloride solutions

“…Urea removes water molecules from Stern and palisade layers and thus decreases the CP. Abuin et al [47] also observed that probe molecules are displaced by urea molecules at the interfacial region, causing a decrease in the slope of I/I o in the post-micellar region. Alkylureas, being bigger in size, replace more water and, therefore, CP decrease is sharper with the alkylureas (see Fig.…”
