Dependence on Oil Chain Length of the Curvature Elastic Properties of Nonionic Surfactant Films: Emulsification Failure and Phase Equilibria

Scattering Functions of Core−Shell-Struct ured Hard Spheres with Schulz-Distributed Radii

“…Indeed, similar SAXS spectra and SANS results have been interpreted on the basis of models of interacting ellipsoidal particles. 48,49 Although the fits of the model to the data are quite reasonable, further improvement is possible by allowing for some hydration of the shells surrounding the droplets. This implies that the condition φ o+s ) 4nπa 2 3 /3 is relaxed and optimization of the …”

“…31 Also, for the scattering of X-rays, the excess electron density of the shell is larger than that of the core for this system. 48 In the modeling we have used a core with an electron density F 1 ) 253 e/nm 3 , a shell with an electron density F 2 , to be determined, while the solvent electron density has been kept constant at F 3 ) 333 e/nm 3 . Similar to findings from the SANS study by Bagger-Jörgensen et al, 31 the SAXS spectra in Figure 4 superpose at large k when scaled by the volume fraction, φ o+s ) φ o + φ s , of oil and surfactant.…”

Nonionic Model Microemulsions to Study Interactions with Active Components and Antioxidant Activity

“…The effect of changing the alkane (decane changed to hexadecane) has also been studied , Balogh, Olsson & Pedersen, 2006. The surfactants and similar systems have been thoroughly investigated trough the massive work by Shinoda and Kuneida (Shinoda & Kunieda, 1973) in Yokohama, Japan and Kahlweit and Strey Göttingen, Germany, later Strey and Sottmann (Sottmann & Strey, 1996) with coworkers in Cologne, Germany.…”

“…This is a general finding for all these systems. There have also been reports on the lamellar phase and that it is not only becoming smaller but actually withdrawing gradually to high concentrations only, with aggregates volume fractions above 0.5 (Balogh, Olsson & Pedersen, 2006, Balogh, 2011. We have not seen reports if this is a general finding for these types of systems or not.…”

“…These model systems stems from research based at Lund University (Olsson & Schurtenberger, 1993) that has been thoroughly investigated and characterized (Balogh, Olsson & Pedersen, 2006, Le et al, 1999Leaver et al, 1994, Leaver et al, 1995, Olsson & Schurtenberger 1993. The effect of changing the alkane (decane changed to hexadecane) has also been studied , Balogh, Olsson & Pedersen, 2006.…”
